Congenital adrenal hyperplasia (CAH), also termed adrenogenital syndrome in older literature, is a common inherited form of adrenal insufficiency. This group of diseases is due to mutations (genetic defects) in the genes coding for several enzymes needed for the production of adrenal cortex hormones. About 95% of cases of CAH are caused by 21-hydroxylase deficiency. This enzyme is necessary for...

Objective(s): Nowadays, the electromagnetic field-emitting devices are used routinely in our lives. Controversial reports exist concerning the effects of mobile radiofrequency (RF) on different parts of the body, especially stress hormones. The main goal of the present work was to study the long-term effects of mobile RF900 MHz exposure with special focus on the adrenal gland pathophysiology an...

testosterone enanthate (te) is used by many athletes as a muscle builder. previous studies showed that high concentration of the drug in plasma may affect the natural function of endocrine glands, specially the secretion of the adrenocortical hormones. the objective of the present study was to examine the effects of high concentration of te on histometrical structure of adrenal cortex in male r...

the hypothalamo-pituitary-adrenocortical (hpa) axis is a critical adaptive system that maximizes survival potential in the face of physical or psychological challenge. the principal end products of the hpa axis, glucocorticoid hormones, act on multiple organ systems, including the brain, to maintain homeostatic balance. the brain is a target of stress, and the hippocampus is the first brain reg...

As stated elsewhere,2 among the many factors that condition the permeability of the ground substance of the mesenchyme, hormones are very important. The present study was undertaken with the view of ascertaining whether hormones from the adrenal cortex were also active in this respect. Menkin7 had already observed that extracts of the adrenal cortex mixed with testicular extracts and injected i...

The adrenal hormones play a central role in response to environmental stimuli, both internal and external. We analyzed enzymes activities (LDHlactate dehydrogenase, GLDHglutamate dehydrogenase and AcPh – acid phosphatase) in adrenal cortex through swimming exercises and under the influence of B-group vitamins. The analyzed cases in the experiment revealed significant increase of enzyme activiti...

Purpose. The interaction of hormones of the pituitary-adrenal axis and adrenal cortex-associated circulating microRNAs is mostly unknown. We have studied the effects of dexamethasone and adrenocorticotropin on the expression of five circulating microRNAs (hsa-miR-27a, hsa-miR-200b, hsa-miR-214, hsa-miR-483-5p, and hsa-miR-503) reported to be related to the adrenal cortex in plasma samples. Meth...

Background: Adrenal gland is an important endocrine that secrets several hormones play a key role in the adaptation of newborn to extra uterine life. The study was conducted explore histomorphological development adrenal glands Gohilwadi Goat (Capra hircus). Methods: research work carried out on twenty pair goat collected from local abattoir. animals were divided into three age groups, viz. gro...

Stress stimulates several adaptive hormonal responses. Prominent among these responses are the secretion of catecholamines from the adrenal medulla, corticosteroids from the adrenal cortex, and adrenocorticotropin from the anterior pituitary. A number of complex interactions are involved in the regulation of these hormones. Glucocorticoids regulate catecholamine biosynthesis in the adrenal medu...
