Serum prolactin levels were studied before and during long-term administration of phenothiazines on a twice daily schedule to 27 newly admitted schizophrenic patients. An increase in serum prolactin is believed to be a reflection of inhibition of dopamine receptors in the hypothalamopituitary axis. By 72 hours after the initiation of treatment, all 27(More)
Peripheral plasma or serum concentrations of glucose, insulin, C-peptide, glucagon, and cortisol and insulin secretory rates (ISR) were determined at 15-min intervals in eight normal subjects during a constant iv infusion of 4.5 mg glucose/kg.min for a 24-h period. During each sampling interval, the secretory rate of insulin was calculated by deconvolution(More)
The acute effects of thyroid hormones on glucocorticoid secretion were studied. Venous blood samples were collected from male rats after they received intravenous 3,5,3'-triiodothyronine (T3) or thyroxine (T4). Zona fasciculata-reticularis (ZFR) cells were treated with adrenocorticotropic hormone (ACTH), T3, T4, ACTH plus T3, or ACTH plus T4 at 37 degrees C(More)
The authors determined serum prolactin levels in 13 patients receiving clozapine, an antipsychotic drug that does not produce extrapyramidal side effects. Morning serum prolactin levels, 11 hours after the last dose, were not elevated during chronic treatment with clozapine in any subject despite its therapeutic effects. Serum prolactin levels were(More)
Thyroid function was evaluated in 46 patients with end-stage kidney disease and 42 normal subjects. Patients were studied before and after the institution of maintenance hemodialysis (HD) and after renal transplantation (RT). Serum total triiodothyronine concentrations (TT(3), ng/100 ml, mean+/-SD) were 63+/-17 and 83+/-22 in the non-HD and HD groups,(More)
Eight rats were subjected to total sleep deprivation, paradoxical sleep deprivation, or high amplitude sleep deprivation until they showed major deprivation-induced changes. Then they were allowed to sleep ad lib. Three rats that had shown the largest temperature declines died within two to six recovery days. During the first 15 days of ad lib sleep,(More)
A patient with classical Albright's pseudohypoparathyroidism was investigated because of oligomenorrhoea. Hypo-oestrogenism was associated with elevated basal gonadotrophin values [mean basal serum LH and FSH were 272 +/- 84 (SD) ng/ml and 593 +/- 83 ng/ml, resplectively (normal less than or equal to 220 and less than or equal to 400, respectively)]. The(More)
Evaluation of testicular function in 13 hemodialyzed patients revealed the following: plasma testosterone (ng/100 ml) was low (less than 300 ng/100 ml) in 6 and low normal in 7 patients; sperm counts ranged from 0 to 8 million/ml and motility from 0 to 8 per cent; testicular tissue from 2 patients showed an abnormal histologic picture ranging from(More)
This follow-up study presents the effects of DES on the genital tract of male and female offspring of mothers who were part of a double-blind, placebo-controlled investigation during 1951 and 1952 aimed at determining the effect of DES on pregnancy. Epididymal cysts, hypotrophic testes, and capsular induration were the more common genital lesions found in(More)
