1. Antler cycles of six adult male axis deer of southern Texas were relatively well synchronized within the herd. The old antlers were cast from December to March and regenerated antlers polished between March and June. The rutting season occurred in June and July. 2. LH and FSH exhibited little seasonal variation (LH 0.7-1.3 ng/ml; FSH 32-65 ng/ml). Prolactin levels were lowest in December (20...

Adrenocortical tumours of the adrenal glands are formed when cells cortical layer grow. The morphological and histological structure benign is variable, which complicates their early diagnosis. study levels hormones in cortex along with analysis symptoms disease will allow not only to differentiate hormone-producing tumours, but also predict direction metabolic processes, make it possible choos...

JANUARY 2009 I REVIEW OF ENDOCRINOLOGY I 19 C ushing’s syndrome is the clinical manifestation of glucocorticoid excess. When the most common cause, exogenous glucocorticoid intake, is excluded, one is left with a group of disorders in which a tumor (or rarely hyperplastic tissue) either produces excess cortisol or stimulates excess cortisol production indirectly through overproduction of either...

ABSTR ACT: Cortisol production is normally under the regulation of adrenocorticotropic hormone (ACTH). Hypercortisolism or Cushing’s syndrome, characterized by excessive cortisol levels, may be caused by ACTH-independent mechanisms. The present work aims to review the current knowledge on ACTH-independent mechanisms through aberrant expression of hormone receptors in adrenal tumors and adrenoco...

In estrogen-dependent rat adrenocortical carcinomas, thymidine kinase activity decreased during tumor regression following removal of estrogen from the host. The change in the kinase activity could be prevented by estrogen administration but not by the administration of growth hormone or adrenocorticotropic hormone. The alterations in kinase activity were not due to changes in the activity of c...

To study the effects of electroconvulsive therapy (ECT) on hormone release, we measured circulating concentrations of adrenocorticotropic hormone (ACTH), prolactin (PRL), growth hormone (GH) and cortisol (CORT) immediately before and at 2 min, 5 min, 15 min, and 30 min following ECT. Compared to pre-ECT concentrations, there were significant increases in post-ECT plasma ACTH, PRL and CORT. GH d...

The rise in hepatic DNA synthesis in response to partial hepatectomy was accelerated in rats subjected to surgery 4.5 to 8 hr or 3 days before hepatectomy. Bovine growth hor mone, in doses from 0.03 to 2.0 mg, also accelerated the response to hepatectomy, but cortisone, hydrocortisone, and adrenocorticotropic hormone were ineffective. Neither surgery nor growth hormone stimulated DNA synthesis ...
