Dopamine (DA) is a principal natriuretic hormone that defends extracellular fluid volume from a Na load. Natriuresis is effected partly through inhibiting the proximal tubule Na/H exchanger NHE-3. Changes in NHE-3 phosphorylation is one mechanism by which NHE-3 activity is regulated.

Involuntary visual spatial attention is captured when a salient cue appears in the visual field. If a target appears soon after the cue, response times to targets at the cue location are faster relative to other locations. However, after longer cue-target intervals, responses to targets at the cue location are slower, due to inhibition of return (IOR). IOR depends on striatal dopamine (DA) levels: It varies with different alleles of the DA transporter gene DAT1 and is reduced in patients with Parkinson's disease, a disease characterized by reduced striatal dopaminergic transmission. We examined the role of DA in involuntary attention and IOR by administering the DA D2 receptor-specific agonist bromocriptine to healthy human subjects. There was no effect of either DAT1 genotype or bromocriptine on involuntary attention, but participants with DAT1 alleles predicting higher striatal DA had a larger IOR. Furthermore, bromocriptine increased the magnitude of IOR in participants with low striatal DA but abolished the IOR in subjects with high striatal DA. This inverted U-shaped pattern resembles previously described relationships between DA levels and performance on cognitive tasks and suggests an involvement of striatal DA in IOR that does not include a role in involuntary attention.

In ten patients with amenorrhea-galactorrhea who had hyperprolactinemia, ovulation could not be induced clomiphene citrate or exogenous gonadotropins. Treatment with bromocryptine in eight of these patients resulted in suppression of PRL in all, cessation of galactorrhea and ovulation in seven and conception in five.

Pathophysiological mechanisms of peripartum cardiomyopathy are not yet completely defined, although there is a strong association with various factors that are already known, including pre-eclampsia. Peripartum cardiomyopathy treatment follows the same recommendations as heart failure with systolic dysfunction. Clinical and experimental studies suggest that products of prolactin degradation can induce this cardiomyopathy. The pharmacological suppression of prolactin production by D2 dopamine receptor agonists bromocriptine and cabergoline has demonstrated satisfactory results in the therapeutic response to the treatment. Here we present a case of an adolescent patient in her first gestation with peripartum cardiomyopathy that evolved to the normalized left ventricular function after cabergoline administration, which was used as an adjuvant in cardiac dysfunction treatment. Subsequently, despite a short interval between pregnancies, the patient exhibited satisfactory progress throughout the entire gestation or puerperium in a new pregnancy without any cardiac alterations. Dopamine agonists that are orally used and are affordable in most tertiary centers, particularly in developing countries, should be considered when treating peripartum cardiomyopathy cases.

A few cases of psychosis induced by clomiphene citrate have been described so far. However, data on the prevalence of psychotic symptoms among women treated for infertility are inconclusive. Still a little is known about possible psychiatric complications of medications used in assisted reproduction techniques (ART). We present a case of a patient who developed transient psychotic symptoms in the course of the in vitro fertilization procedures. To our kiiowledge, this is the first case of 'mid-stimulation psychosis', which has been observed during ART using clomiphene.citrate and bromocriptine. The aim of this study is to describe the determinants ofpharmacotherapy undertaken in ART,.which can result in the development of psychotic symptoms.

A 68-year-old male patient presented with visual impairment due to a large pituitary tumor. After transsphenoidal adenomectomy the elevated serum FSH levels were lowered but not normalized. Deterioration of the vision was detected five years later and tumor regrowth was evidenced. The patient was treated with the long-acting and repeatable form of bromocriptine (Parlodel-LAR). Three days after the first intramuscular injection it already resulted in an important improvement of the visual field defects. Serum FSH concentration was suppressed during a prolonged period, but no change in the size of the pituitary adenoma was recorded on CT scan. Long-term oral treatment with bromocriptine resulted in a sustained suppression of the serum FSH levels, without further visual improvement, but with a significant reduction of the volume of the adenoma. The rapid and prolonged effect of Parlodel-LAR upon the FSH secretion, with a possible correction of the visual field defects and a reduction of the tumor mass, could make this medication appropriate as adjunctive treatment in some gonadotroph cell adenomas.

bromocriptine parlodel dosage

The response of prolactin receptor and lactose synthetase to suppression of plasma concentrations of prolactin was examined in normal and occluded (teat-sealed) mammary glands of Sprague-Dawley rats, Rats, with mammary glands unilaterally occluded, were given bromocriptine (2.5 mg/kg per 12 h) between 5 and 8 post partum. Bromocriptine reduced plasma prolactin concentrations from 460.4 +/- 120.8 (mean +/- s.e.m.) to 2.56 +/- 0.89 ng/ml within 12h whilst concentrations in control rats were 553.4 +/- 110.25 ng/ml. Lactose synthetase activity declined rapidly, within 24h, in occluded glands of both groups but was maintained for 24 h in normal glands of bromocriptine-treated rats and decreased thereafter. Prolactin receptors also declined significantly within 24h in occluded glands. Desaturation of the prolactin receptor by bromocriptine treatment in vivo was compared with desaturation by exposure of membranes to MgCl2 in vitro. Both treatments enhanced prolactin binding but the increase after treatment with MgCl2 may have been partly artefactual since there was a selective loss of protein from the membranes. These results indicate that the prolactin receptor in rat mammary gland may be maintained after acute suppression of prolactin secretion.

The prevalence of known cases of acromegaly in Northern Ireland in 1984 was 6.3 per 100,000 population. The incidence of newly-diagnosed cases over the preceding 25 years was 5.5 patients per year, or 0.4 patients per 100,000 population per year. This rate would be equivalent to about 200 new cases per year in the United Kingdom. Four options have been available to most of these patients--surgical hypophysectomy (transfrontal or transsphenoidal), pituitary radiotherapy (usually external cobalt beam), drug treatment with bromocriptine, or no treatment. Choice of treatment has been mainly influenced by tumour size, with the larger pituitary adenomas having surgery initially. No single form of treatment has been successful in achieving a clinical remission or cure in more than a minority of cases. The most successful outcome has been where total pituitary ablation has been achieved. Life-table analysis for the whole group shows life expectancy which is not markedly different for that of an age-matched population from Northern Ireland. Morbidity related to long term osteoarthritis and treatment complications remain a major problem. The incidence of malignant tumours is higher than would be expected.

The neuroleptic malignant syndrome (NMS) occurs as a hypersensitivity response in certain patients exposed to neuroleptics. It is a relatively rare, but potentially lethal complication, the incidence of which may have been underestimated. Recent interest in NMS has arisen due to the recognition that specific therapy may now be available. This review summarises the clinical features and discusses recent ideas regarding aetiology and treatment.

bromocriptine parlodel dose

Five patients, 3 women and 2 men, with macroprolactinomas characterized by extrasellar extension and basal plasma prolactin levels ranging from 4.6 to 102 U/l received six monthly injections of 50-100 mg Parlodel LAR, an injectable long-acting repeatable form of bromocriptine. The following observations were made: 1. Plasma prolactin levels fell dramatically in all patients and values in the normal range were obtained in 3 patients. 2. In all patients, the onset of tumour reduction was visible on CT scans made one week after the first Parlodel LAR injection. After six Parlodel LAR injections, tumour size was reduced by more than 75% in 3 patients and by 50-75% in two patients. 3. Diminished visual acuity (one patient), bitemporal hemianopia (2 patients), and oculomotor and trochlear nerve dysfunction (one patient) were restored to normal after the first Parlodel LAR injection. 4. Hypogonadism normalized in 2 patients and improved in one patient, whereas plasma gonadotropins remained low in the 2 postmenopausal women. In one patient with hypothyroidism and hypocorticism, thyroid and adrenal functions normalized. It is concluded that bromocriptine retard (50-100 mg monthly) is a useful alternative for oral treatment of patients with prolactinomas, especially in those patients with compliance problems on oral bromocriptine therapy.

Slices for immunohistochemical pathology were randomly selected from 37 paraffin-embedded prolactinoma tissue sections. LC3 was detected by immunohistochemistry. GH3 and MMQ cells were treated by BRC and/or rapamycin (RAPA). Cell viability and the cell cycle were measured by CCK-8 and flow cytometry, respectively. ELISA measured prolactin secretion. Protein expression was detected by Western blot or immunofluorescence.

Seventy-three hyperprolactinaemic women were followed up with radiographic examinations (lateral and posteroanterior coned down views) of the sella turcica for 5 to 13 years during which time all but one had received treatment with bromocriptine. Progression of the sellar asymmetry occurred in 25 women (7 during pregnancy), 14 had regression of their changes in the pituitary fossa while 34 did not show any changes in the configuration of the sella turcica. Prolactin levels in serum, duration of bromocriptine therapy or sellar configuration could not predict later radiographic progressive or regressive changes of the sella turcica. The clinical course was benign in the majority of the women with signs of prolactin-producing adenomas. The risk of serious tumour enlargement seems to be very small. We were not able to demonstrate any parameter which could predict the growth or shrinkage of the tumour. Routinely repeated radiographic sellar examinations are unnecessary in the vast majority of hyperprolactinaemic women.

Eight monkeys developed a severe parkinsonian syndrome after i.v. administration of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Treatment with bromocriptine (5 mg/kg) relieved the parkinsonian symptoms, but the efficacy of this treatment appeared to decrease slightly with time. The addition of SKF38393 (5 mg/kg) to the bromocriptine treatment in four monkeys prevented and even reversed the tendency to decreased efficacy with an increased response in three out of four animals. Neither of these two treatments induced dyskinesia in these monkeys. Dopamine D1 and D2 receptors, assayed in the caudate nucleus, the putamen and nucleus accumbens with [3H]SCH 23390 and [3H]spiperone binding respectively, were not significantly different in MPTP monkeys treated with bromocriptine or with bromocriptine plus SKF38393. Monkeys in the two treatment groups had a similar extent of denervation of the striatum and accumbens as assessed by the content of dopamine and its metabolites. These results suggest that in MPTP monkeys, the behavioral response to the D2 agonist bromocriptine can be enhanced by concomitant activation of the D1 receptors while this combination of agonists does not induce dyskinesia. The addition of the D1 agonist does not appear to cause further alteration of the D1 or D2 receptors.

We performed a case-controlled analysis on the effectiveness of dantrolene and certain dopamine agonists--bromocriptine, amantadine 3,4-dihydroxyphenylalanine, (DOPA)--for the neuroleptic malignant syndrome (NMS). This was based on a review of all known published studies using as controls those cases not treated with these drugs and/or electroconvulsive therapy. In this control group, the NMS-related death rate was 21 percent. Dantrolene alone reduced the death rate to 8.6 percent, bromocriptine alone to 7.8 percent, and amantadine alone to 5.9 percent. We also stratified patients into five levels of severity based on state of consciousness and temperature and showed that the relative reduction in death rate held up at all levels. The dopamine agonists and dantrolene have a therapeutic effect independent of each other.

Women are most susceptible to psychotic reactions during the postpartum period, a time of intense psychological and physiological stress. Mania and depression are particularly common at this time, especially in women with past or family histories of major or minor affective disorders, specifically cyclothymia and dysthymia. Close attention after childbirth is warranted to alleviate and prevent these episodes in such women. Sympathomimetic drugs such as bromocriptine and the over-the-counter diet aids, which are linked to the induction of manic episodes, are frequently used in the puerperal period and may act as catalysts. This case report documents a postpartum manic episode in a cyclothymic woman who was prescribed bromocriptine, a dopamine agonist, for prevention of lactation.

Ropinirole is a non-ergot dopaminergic agonist with a high affinity for D2 dopaminergic receptors which improves the symptoms of Parkinson's disease (PD) and delays the appearance of motor complications. It is different to the first generation of dopaminergic agonists in that, because it lacks an ergolinic structure, it does not have the side effects that usually appear with the use of this pharmacological group.

Despite the availability and application of more effective antihypertensive drugs over the past 3 decades, hypertension continues to be a major risk factor for the development of premature cardiovascular disease. Moreover, failure to elucidate the pathogenesis of essential hypertension, noncompliance, and difficulties in defining the appropriate level of blood pressure elevation requiring therapy, continue to mitigate against the adequate control of hypertension. Some of these problems may be overcome by the availability of depot forms of antihypertensive medication or implantable drug delivery systems, or by the use of several recently developed antihypertensive drugs. These include dopaminergic agonists, selective alpha-adrenergic agents, calcium antagonists, medullary neutral lipids, gamma-aminobutyric acid agonists, and inhibitors of renin or phenethylamine N-methyl-transferase. In addition, the potential involvement of morphinomimetic peptides, prostaglandins, tonin, and bradykinin in blood pressure control or certain hypertensive states suggests that drugs developed to block or potentiate the actions of these substances may have important therapeutic applications.

One of the most important causes of anticancer treatment failure is the development of multidrug resistance (MDR). The main characteristics of tumor cells displaying the MDR phenomena are cross-resistance to structurally unrelated cytotoxic drugs having different mechanisms of action and the overexpression of the MDR1 gene, which encodes a transmembrane glycoprotein named P-glycoprotein (P-gp). This study evaluated whether bromocriptine, a D2 dopaminergic receptor agonist, influenced anticancer drug cytotoxicity and P-gp activity in a P-gp-expressing cell line compared to a non-expressing subline. The K(i) values for P-gp of cyclosporine and verapamil were 1.09 and 540 microM, respectively, and that of bromocriptine was 6.52 microM in a calcein-AM efflux assay using porcine kidney epithelial LLC-PK1 and L-MDR1 cells, overexpressing human P-gp. Bromocriptine at 10 microM reduced the IC50 of doxorubicin (DXR) in K562-DXR from 9000 to 270 ng/ml and that of vincristine (VCR) in K562-VCR from 700 to 0.30 ng/ml, whereas the IC50 values of DXR and VCR in the K562 subline were only marginally affected by these drugs. Bromocriptine restored the anticancer effect of DXR, VCR, vinblastine, vinorelbine and etoposide on MDR-tumor cells overexpressing P-gp. These observations suggest that bromocriptine has the potential to reverse tumor MDR involving the efflux protein P-gp in the clinical situation.

Injection of an ovulation-blocking dose of pentobarbitone sodium given in the early afternoon of pro-oestrus in rats decreased follicular oestradiol production in vitro the next day (2.42 +/- 0.11 ng/4 h/follicle in pro-oestrous rats, 0.49 +/- 0.04 ng/4 h/follicle in pentobarbitone-treated rats). Pentobarbitone, given 1 day earlier (at dioestrus II), prevented the increase in oestradiol production that normally occurs between di-oestrus II and pro-oestrus. Injection of a subovulatory amount of hCG (0.5 i.u.) given after pentobarbitone injection inhibited the decrease in follicular oestradiol production induced by pentobarbitone. The pentobarbitone-induced decrease in oestradiol production was also prevented by bromocriptine (1 mg) given at di-oestrus II (15:00 h) and pro-oestrus (09:00 h). Bromocriptine is an effective inhibitor of prolactin secretion and this suggests therefore that the decrease in follicular oestradiol production after pentobarbitone is due to the preovulatory surge of prolactin. However, pretreatment with bromocriptine also inhibited the effect of pentobarbitone on oestradiol production when pentobarbitone was given at di-oestrus II. Moreover, when ergocornine (another inhibitor of prolactin secretion) was used instead of pentobarbitone to block ovulation, follicular oestradiol production was also decreased the next day. In contrast to bromocriptine, ergocornine was not able to prevent the pentobarbitone-induced decrease in follicular oestradiol production. These results indicate that the decrease in follicular oestradiol production after pentobarbitone injection is due to inhibition of the serum concentrations of LH rather than the preovulatory surge of prolactin. How bromocriptine (but not ergocornine) prevents the pentobarbitone-induced decrease in oestradiol production is not clear.

Significantly more embryos were cleaved and had superior morphology in group 1 than group 2. Clinical and ongoing pregnancy rates per oocyte pick-up were significantly higher in group 1 (42% and 38%, respectively) than group 2 (24% and 21%, respectively). The mean PRL concentration was significantly higher in the group 1 than group 2. A significant correlation between the number of superior embryos and PRL concentrations was observed in group 1, but not in group 2.

The clinical use of bromocriptine (2.5 mg twice daily) was investigated in 40 women attending an infertility clinic and presenting with secondary amenorrhoea (18) or with ovarian dysfunction (22) which had failed to respond to anti-oestrogen therapy. Patients in each group were sub-divided into those with raised and those with normal prolactin levels, and re-examined at 3 and 12 months after the start of treatment. The results confirmed that bromocriptine is effective in the treatment of hyperprolactinaemic states whether there is amenorrhoea or not. Moreover, in cases of ovarian dysfunction as well as of amenorrhoea where the prolactin levels were within the normal range, there was evidence to suggest that bromocriptine can be associated with a return of ovulation, although the mechanism by which it might do so still needs evaluation.

In 27 pregnant subjects (21 treated women and six control subjects), the effect of buy parlodel L-dopa (500 to 1,000 mg orally) on vascular sensitivity to angiotensin II amide (Hypertensin, Ciba) was examined in 16 of these women, 1,000 mg of L-dopa resulted in a significant decrease in vascular responsiveness to angiotensin, i.e., an increase in angiotensin pressor dose from 16.9 +/- 5.0 to 19.6 +/- 4.5 ng . kg-1 . min-1 (mean +/- SD). In women with an initially low angiotensin pressor dose, the changes were more pronounced. In six control subjects, in whom two angiotensin infusion tests were performed consecutively without additional administration of L-dopa, an increase in vasopressor response to angiotensin was demonstrated. Possible causes for the L-dopa-induced decrease in angiotensin sensitivity are discussed: an inhibition of sympathetic nervous activity, a directly lowered total peripheral resistance, a natriuresis and diuresis, and an altered dopaminergic activity in the hypothalamus. It is hypothesized that long-term treatment with L-dopa or bromocriptine might not only decrease angiotensin sensitivity but also elevated pregnancy-induced hypertension.

Slices of rabbit caudate nucleus were preincubated with 3H-dopamine and then superfused. 3H-dopamine and its metabolites were separated by column chromatography. The basal outflow of tritium consisted of 68% DOPAC, 21% OMDA metabolites (most of which was HVA), 6% dopamine and 5% MTA. Except for an increase in 3H-dopamine, the basal outflow was little changed by nomifensine or cocaine. Amezinium reduced the outflow of 3H-DOPAC and 3H-OMDA metabolites and increased that of 3H-dopamine and 3H-MTA; its effect was antagonized by nomifensine. Haloperidol 10(-7) M selectively enhanced the outflow of 3H-DOPAC and 3H-OMDA metabolites. At haloperidol 10(-5) M, a large increase in these two fractions was accompanied by a small increase in 3H-dopamine and 3H-MTA. Nomifensine diminished only slightly the outflow of 3H-DOPAC caused by buy parlodel haloperidol. The overflow of tritium elicited by electrical stimulation at 3 Hz consisted of 74% DOPAC, 15% OMDA metabolites, 10% dopamine and 0.4% MTA. Lowering the frequency reduced the overflow of total tritium and caused a decrease in the percentage of 3H-DOPAC and an increase in the percentage of 3H-dopamine. Nomifensine or cocaine greatly diminished the evoked overflow of 3H-DOPAC and 3H-OMDA compounds and increased the evoked overflow of 3H-dopamine and 3H-MTA. The effects of apomorphine and bromocriptine were similar to those caused by decreasing the stimulation frequency. The major pathways of the metabolism of previously taken up dopamine, under the conditions of our experiments, are as follows. When the neurones are at rest, dopamine metabolism is initiated by leakage of the amine into the axoplasm, where it is degraded through the aldehyde to DOPAC. Part of the DOPAC is methylated extraneuronally to HVA. Traces of MTA are formed by extraneuronal methylation of dopamine. When action potentials arrive, dopamine metabolism is initiated by exocytosis. The bulk of the extracellular dopamine is taken up back into the neurones. When the stimulation frequency is 3 Hz, most of the axoplasmic dopamine is subsequently transformed to DOPAC; little seems to be re-stored. HVA and MTA are generated essentially as during neuronal rest. When dopamine release is low (stimulation at low frequency; addition of apomorphine or bromocriptine), a larger portion seems to be re-stored, thus leading to a decrease in the percentage of DOPAC. Haloperidol, apart from its receptor blocking properties, acts on dopaminergic axons in a manner akin to the effect of reserpine.

The effects of bromocriptine (CB-154) on the proliferative capacities of prolactinoma and somatotropinoma were investigated by immunocytochemical staining indices of proliferating cell nuclear antigen (PCNA) and Ki-67 (with MIB-1 antibody), and silver staining of nucleolar organizer region (NOR) number in histological sections. Patients with prolactinoma and somatotropinoma were divided into two groups: no preoperative treatment (control group), and treated with CB-154 for 2 weeks before adenomectomy (CB-154 group). The prolactinoma CB-154 group showed a significantly lower PCNA staining index (n = 6, 13.1 +/- 2.0%) and Ki-67 staining index (n = 6, 0.2 +/- 0.03%) than the control group (n = 4, 27.1 +/- 2.1%; n = 8, 1.9 +/- 0.5%; respectively) (p < 0.01). The somatotropinoma CB-154 group showed a significantly lower Ki-67 staining index (n = 5, 0.7 +/- 0.07%) than the control group (n = 11, 1.2 +/- 0.2 buy parlodel %) (p < 0.05), but there was no significant difference in PCNA staining index (control: n = 5, 19.1 +/- 2.8% vs. CB-154: n = 5, 20.2 +/- 1.4%). However, variable intensities of PCNA staining between the cells were observed, resulting in an extraordinarily high staining index. NOR numbers did not vary significantly between the two prolactinoma groups (control: n = 4, 2.0 +/- 0.3 vs. CB-154: n = 6, 1.7 +/- 0.1) and two somatotropinoma groups (control: n = 5, 1.3 +/- 0.1 vs. CB-154: n = 5, 1.4 +/- 0.2).(ABSTRACT TRUNCATED AT 250 WORDS)

Pertussis toxin, a protein exotoxin produced by Bordetella pertussis, markedly reduced or eliminated the ability of dopamine or the dopamine agonist bromocriptine to inhibit prolactin release from anterior pituitary cells in vitro. Toxin-mediated reversal of the effect on dopamine agonist inhibition of prolactin release occurred with a lag of greater than 6 h, was maximal by 24 h, and persisted for at least 6 days after removal of the toxin from the medium. The toxin reduced dopamine agonist efficacy without altering potency or directly modifying the dopamine receptor (as measured by [3H]spiperone binding). The ability of dopamine to reduce cellular cyclic AMP content was also antagonized by pertussis toxin, supporting the hypothesis that reduction of cellular cyclic AMP content and inhibition of prolactin secretion may buy parlodel be causally related. These data demonstrated that pertussis toxin can prevent the typical inhibitory action of dopamine agonists on anterior pituitary prolactin release and suggest that this receptor-mediated inhibitory hormone system is analogous to other inhibitory receptors coupled to adenylate cyclase.

At 49 years of age, he developed depression and was administrated 50 mg amoxapine, 4 mg cloxazoram and 3 mg biperiden per day. The daily dose of amoxapine was gradually increased up to 150 mg at 58 years of age. At 61 years of age and after having been taking amoxapine for twelve years, he noticed a rotating left arm and muscle pain in his left shoulder and arm while walking. At 62 years of age, he stopped taking these three drugs. However, the dystonic movements and pain both continued to get worse. buy parlodel Neurological findings revealed no abnormality except for a dystonic posture and movements in the neck and bilateral arms while sitting, standing and walking. Positron emission tomography with C-11 raclopride revealed a mild decrease in the dopamine D 2 receptor numbers in the bilateral striatum. However, two dopamine agonists, pergolide and bromocriptine, worsened his dystonia. In contrast, the daily administration of 2 mg of trihexyphenidyl, an anti-cholinergic agent, markedly ameliorated the dystonia symptoms. As a result, the long-term co-administration of biperiden, an anti-cholinergic agent, may mask the toxicity of amoxapine, which may induce tardive dystonia.

An acceptable level of motor improvement allows the patient to do the physical tasks necessary for independent functioning. Patients achieve this level of improvement, on an average, with less than six tablets daily of 25/100 carbidopa/L-dopa. Bromocriptine mesylate, one of the dopamine agonist drugs, may be used in patients without the concomitant use of other agents. However, my experience suggests buy parlodel it is more effective in conjunction with carbidopa and L-dopa.

This article summarizes the prevention and treatment of malignant syndrome (MS) in Parkinson's disease. MS is often induced by sudden withdrawal of levodopa. However, many other events can be responsible for the induction of MS, including concomitant infections, dehydration, hot weather, discontinuation of other antiparkinsonian drugs, and 'wearing off' phenomenon. MS should be suspected when the body temperature rises above 38 degrees C without an apparent cause. The early detection and its prompt commencement of treatment buy parlodel are essential for improving the prognosis of the disease. The treatment consists of ample intravenous fluid, cooling the body, antiparkinsonian drugs (particularly, levodopa and bromocriptine), dantrolene sodium, and antibiotics if infection is present.

Gilts were assigned as controls (CTL, n = 6) or received orally 10 mg buy parlodel of bromocriptine thrice daily from d 110 of gestation until farrowing, (BRPP, n = 7), from d 1 to 6 postpartum (PP) (BRL1, n = 6), from d 7 to 13 PP (BRL2, n = 7), from d 14 to 20 PP (BRL3, n = 6), or from d 21 to 27 PP (BRL4, n = 6). Weights of pigs were recorded at birth, 24 h later, and on d 7, 14, 21, 28, 31 (weaning), 42, and 56 PP. Jugular blood samples were collected from sows on d 109 of gestation and every other day until farrowing, as well as on d 1, 6, 13, 20, and 27 PP. Behavioral observations of sows and litters were taken every 3 min for a 24-h period beginning 48 h after the onset of the treatments. In experimental sows, bromocriptine induced marked reductions in prolactin levels during treatment (P < .001). Compared to CTL sows, concentrations of IGF-I were higher at d 21 (P = .01) and 28 (P = .003) PP in BRL3 and BRL4 sows, respectively. In bromocriptine-treated sows, weight gain of litters was either drastically reduced or abolished (P < .001) during the week of treatment. Treatments also altered significantly the suckling behavior of pigs at all stages studied. Therefore, the present results strongly suggest that prolactin is essential for the initiation and the maintenance of milk production in sows. Results also indicate that prolactin does not seem to be involved in the maintenance of lactational anestrus during a 4-wk lactation.

A 28 year-old man with chronic hepatitis B was administered interferon-alpha (5 x 10(6) IU) intramuscularly once a day for 28 days. Eight days after the end of interferon treatment, he showed signs of inability to sit still for ten seconds and walked around constantly. His akathisia symptoms worsened thereafter. Clonazepam, thioridazine, beta-blockers, anticholinergics, and bromocriptine did not ameliorate his akathisia. Two days' administration of levomepromazine 100 mg led him to a coma for 2 days. Intravenous levodopa 25 mg ameliorated his akathisia symptoms drastically. He became completely premorbid 2 weeks after administration of levodopa. The present report illustrates a rare case of refractory akathisia after interferon-alpha treatment and also that levodopa treatment would be theoretically and practically useful in reducing the neurotoxicity associated Zantac 150 Tablets with interferon-alpha.

Seventy-three patients with active acromegaly were treated for three to 25 months with bromocriptine 10-60 mg/day. Seventy-one patients showed symptomatic and objective clinical improvement. This included reduction in excessive sweating, hand and foot size, and Lamictal Increased Dosage the number of headaches; improved facial appearance; and increased energy and libido. Abnormal visual fields became normal in two patients, one of whom had concomitant radiotherapy. Mean circulating growth hormone levels, obtained by averaging serial samples through the day, fell by more than 7 microng/l or became undetectable in 58 patients (79%) but did not reach normal values: only 15 patients had mean levels on treatment of 5 microng/l or less. Twenty-three patients were diabetic before treatment, and glucose tolerance became normal in 15 and improved in a further five. Provided the drug was started slowly side effects were minor when compared with the considerable clinical benefit obtained.

Effects of dopamine agonists upon phrenic output were studied in decerebrate, vagotomized, paralyzed, carotid-body denervated dogs. Intravenous administration of dopamine was without effect in these dogs. Apomorphine (APO) increased phrenic minute activity while bromocriptine (BRO) decreased phrenic minute activity following intravenous injection at doses of 100 micrograms/kg for each drug. BRO-induced decreases in phrenic minute activity were associated with decreases in phrenic amplitude; burst frequency remained unchanged. Conversely, APO-induced increases in phrenic minute activity resulted from significant increases in both frequency and amplitude. Both APO and BRO significantly prolonged inspiratory duration and shortened expiratory duration. Responses to APO and BRO were abolished with haloperidol. These results confirm previous evidence for the existence of dopaminergic receptors within the central nervous system, which are inaccessible to exogenous dopamine, and Priligy With Alcohol which can alter timing as well as amplitude characteristics of the integrated phrenic neurogram. Both excitation and inhibition of phrenic activity following administration of APO and BRO are mediated by mechanisms within or below the caudal brainstem.

Microiontophoretic experiments were performed to determine whether inhibition mediated by the ventral tegmental area neurons of the nucleus accumbens, receiving input from the parafascicular nucleus of thalamus, is mediated by dopamine D1 or D2 receptors, using rats anesthetized with chloral hydrate. Spikes, elicited by test stimuli applied to the parafascicular nucleus were inhibited by conditioning stimuli to the ventral tegmental area, given 30 msec before the test stimuli. This inhibition was antagonized by iontophoretic application of SCH 23390, a D1 antagonist, in 18 of 25 neurons of the nucleus accumbens, but in only 3 of 22 neurons of the nucleus accumbens during application of domperidone, a D2 antagonist. The reduction by conditioning stimulation of the ventral tegmental area of the mean number of spikes of the 25 neurons upon stimulation of the parafascicular nucleus, was abolished by SCH 23390. In contrast, domperidone did not affect the mean number of spikes of the 22 neurons upon stimulation of the parafascicular nucleus in the presence of conditioning stimulation of the ventral tegmental area. In addition, spikes elicited by stimulation of the parafascicular nucleus were dose-dependently inhibited by iontophoretic application of both Desyrel Online SKF 38393, a D1 agonist and bromocriptine, a D2 agonist. These results suggest that inhibition by dopamine, derived from the ventral tegmental area of neurons of the nucleus accumbens, receiving input from the parafascicular nucleus, is mediated mainly by dopamine D1 receptors, although both D1 and D2 receptors are expressed on the same neuron of the nucleus accumbens, which is also inhibited by exogenously applied D2 agonists.

Prolactin (PRL), growth hormone (GH), placental lactogen (PL), chorionic gonadotropin (CG), estradiol (OE), progesterone (P4) and sex hormone-binding globulin (SHBG) were measured in serum throughout gestation in 9 women with PRL-producing pituitary adenomas. They had been treated at least 1 year with the dopamine agonist bromocriptine before pregnancy occurred. All women bore healthy babies of normal birthweight. Their PRL levels did not show the successive increase seen in normal pregnancies; serum PRL was unphysiologically increased in all patients up to the 20th week of gestation, whereafter PRL levelled off and fell within the normal range. Serum PL levels were lower in the women with prolactinoma compared to healthy pregnant women, despite normal placental weight. The serum GH levels in the patients determined with an immunoassay Coreg Normal Dose based on a monoclonal antibody, were low or nondetectable, similar to healthy pregnant controls. In contrast, high molecular weight GH in serum as determined with a monoclonal antibody which also recognizes PL appeared to be increased in comparison with healthy pregnant women. The serum levels of CG, OE, P4 and SHBG were all within the normal range. These results show that the unphysiological secretion of PRL in pregnant women with PRL-producing pituitary adenomas is associated with decreased serum levels of PL.

Prolactinomas are one of the most frequent tumors of the human anterior pituitary. Dopamine agonists are the choice in the medical treatment of this disease. Bromocriptine (BC) is a well known anti-neoplasic agent in human PRL secreting adenomas although its effect on PRL cells is far from clear. We decided to investigate its influence on Ceftin Tabs cell proliferation parameters: (3H)thymidine incorporation, expression of c-myc and c-fos, and number of estrogen receptors present in the samples. A total of 28 patients were included in this protocol. They were treated with BC (5-7.5mg day(-1) patient(-1)) or with vehicle orally 15 days before surgery. We found that in BC treated patients (3H)thymidine incorporation was lower than in vehicle treated patients. The oncogenes expression were diminished in BC comparing with vehicle-treated patients. No difference in the number of estrogen receptors was observed in the samples from BC or vehicle-treated patients. These results clearly demonstrate that one mechanism to reduce the size of human PRL secreting adenomas by BC is the inhibition of DNA duplication.

Chronic administration of an estrogenic agent is well known to attenuate the drinking response of rats to treatment with a variety of dipsogenic agents, and to increase plasma concentration of prolactin. Treatment with prolactin is also known to reduce the drinking response to administration of the dipsogenic agent, isoproterenol. Hence, a possibility existed that the antidipsogenic effect of chronic treatment with estrogen was Adalat Xl Reviews mediated by an increased plasma prolactin concentration. Since bromocriptine, a dopaminergic agonist, is known to reduce plasma prolactin concentration in estrogen-treated rats, it was administered (1.0 mg/kg, IP) 15 min prior to treatment with either isoproterenol (25 micrograms/kg, SC) or angiotensin II (200 micrograms/kg, SC). The results suggest that the antidipsogenic effect of chronic treatment of rats with estradiol benzoate (30.4 and 45.7 micrograms/kg/day) can be reversed, at least partially, by acute administration of bromocriptine.

The characteristics of [3H]spiperone interactions with rat striatal dopamine D-2 receptor were investigated. Although the association of [3H]spiperone occurred monoexponentially, the pseudo-first order rate constant of association showed a hyperbolic dependence on ligand concentration. The data were therefore analyzed with the assumption of a two-step binding reaction leading to ligand-induced receptor isomerization. For the first equilibrium, the dissociation constant (KD) was 1.2 nM, while for the second equilibrium, the association and the dissociation rate constants were 71.6 X 10(-3) sec-1 and 0.9 X 10(-3) sec-1, respectively. The dissociation rate constant of the overall binding reaction, as determined by inducing the dissociation of [3H]spiperone from its binding sites by 1 microM (+)-butaclamol, was 0.92 X 10(-3) sec-1. However, the kinetically derived KD (15 pM) of the binding reaction differed significantly from the KD (218 pM) obtained from equilibrium binding experiments. This inconsistency between the two KD values appeared to have arisen from using different receptor concentrations in deriving kinetic and equilibrium data. The KD of the equilibrium binding reaction indeed showed significant variation with the receptor concentrations in an inverse way, implicating the involvement of a third component in the two-step binding reaction to form a high affinity ternary complex rather than a simple ligand induced receptor isomerization. Pretreatment of the membrane with 0.1 mM guanosine 5'-imidodiphosphate [Gpp(NH)p] reduced the affinity of the equilibrium binding reaction to a value (KD = 1.2 nM) which corresponded to the kinetically derived KD of the first step of the binding reaction, indicating the involvement of a guanine nucleotide-binding protein or G protein in inducing the formation of the high affinity ternary complex. The affinity of the binding reaction in Gpp(NH)p-pretreated membranes, however, increased with the duration of incubation, indicating that the ligand receptor complex still can couple with the G protein even in the presence of Gpp(NH)p. Pretreatment of the membrane with pertussis toxin irreversibly decreased the affinity of the binding reaction without significantly affecting the total number of binding sites, implying the involvement of the Gi subclass of G protein in the interaction of [3H]spiperone with D-2 receptors. Inhibition of the [3H]spiperone binding by a dopamine receptor agonist, bromocriptine, also yielded a monophasic dose response curve both in the presence Cipro Otic Dosage and in the absence of Gpp(NH)p.(ABSTRACT TRUNCATED AT 400 WORDS)
