Because of the time factor involved, it would be an impossible task to present the vast body of biochemical information accumulated during the last decade on the endocrine aspects of pregnancy. However, certain key points can be made concerning the feto-placental unit and the hormone levels and effects in normal gestation. These concepts will be discussed not merely for their academic value, bu...

Introduction: Psychological stresses influence brain functions such as learning and memory. Environmental factors like types and durations of stress affect brain responsiveness. This study investigated the effects of two subchronic social and isolation stresses on learning, memory, adrenal glands weight and corticosterone levels in the hippocampus and frontal cortex. Methods: Eighteen male ...

The adrenal glands consist of an outer cortex and an inner medulla, and their primary purposes include hormone synthesis and secretion. The adrenal cortex produces a complex array of steroid hormones, whereas the medulla is part of the sympathetic nervous system and produces the catecholamines epinephrine and norepinephrine. In the mouse, GATA binding protein (GATA) 4 and GATA6 transcription fa...

Abstract The adult human adrenal cortex produces steroid hormones that are crucial for life, supporting immune response, glucose homeostasis, salt balance and sexual maturation. It consists of three histologically distinct functionally specialized zones. fetal forms from mesodermal material predominantly C19 steroids its zone, which involutes after birth. Transition to the occurs immediately bi...

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...

The salicylates have been used in the symptomatic treatment of rheumatic disorders for over 50 years. They are capable of producing a striking change in the clinical picture of acute rheumatic fever and possess a smaller, but still definite, effect in rheumatoid arthritis. Their value as suppressive drugs appears to be concerned with alleviating the symptoms produced by the inflammatory process...

Psychologic states produced by environmental or physiologic stresses are usually associated with hypersecretion of adrenal hormones, particularly epinephrine and the glucocorticoids (hydrocortisone in humans or corticosterone in rats). A common mechanism links the secretion of these hormones, even though the adrenal medulla and cortex have different embryologic origins and biochemical propertie...

During the past several years, an investigation has been made of the relationships between various hormones of the adrenal cortex, the enzyme hyaluronidase, and its substrate hyaluronic acid, with specific reference to tissue permeability and collagen diseases. As the studies progressed, several problems were investigated: (i) which fractions of the adrenal cortex were responsible for the resul...

The adrenal glands produce a variety of hormones that play a key role in the regulation of blood pressure, electrolyte homeostasis, metabolism, immune system suppression, and the body's physiologic response to stress. Adrenal neoplasms can be asymptomatic or can overproduce certain hormones that lead to different clinical manifestations. Oncocytic adrenal neoplasms are infrequent tumors that ar...
