It is well established that an administration of histamine results in a marked increase in adrenal cortical (Suzuki et al. 1963, Katsuki et al. 1967, Tanigawa 1967) as well as adrenal medullary (Wada et al. 1940, De Schaepdryver 1959, Robinson and Jochim 1960, Athos et al. 1962, Staszewska-Barczak and Vane 1965) secretion. Since the differential response of the adrenal cortex and medulla to bac...

Steroid hormone biosynthesis by the fetal adrenal gland is crucial to the integrity and continuation of pregnancy, growth of the fetal and maternal tissues, as well as perinatal homeostatic adaptation for extrauterine survival. The adrenal cortex in the primate undergoes a remarkable morphological and functional remodeling such that the fetal adrenal cortex transforms into an adult adrenal cort...

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...

BACKGROUND Newer, energy-based devices like the ultrasonic coagulator (Harmonic Scalpel, Ethicon Endo-Surgery, Inc., Cincinnati, OH) and the LigaSure vessel-sealing system (Valleylab, Boulder, CO) are increasingly being used in advanced laparoscopic procedures. Use of these devices has resulted in shorter operative time, less blood loss, and lower conversion rates. We present our experience wit...

Orexin-A and orexin-B are hypothalamic peptides that act via two G protein-coupled receptors, named orexin type 1 and type 2 receptors (OX1-Rs and OX2-Rs). The most studied biological functions of orexins are the central control of feeding and sleep, but in the past few years findings that orexin system modulates the hypothalamic-pituitary-adrenal (HPA) axis, acting on both its central and peri...

Lewy body disease is defined as Lewy body-related neuronal degeneration involving the nigrostriatal system, limbic-neocortical system, and peripheral autonomic nervous system (PANS). We investigated whether the adrenal gland, which is evolutionarily related to sympathetic ganglia and is routinely examined in general autopsy, could be used to assess pathology of the PANS in Lewy body disease. Br...

allgrove syndrome also known as triple-a syndrome is an autosomal recessive disorder characterized by alacremia, achalasia and acth-resistant adrenal insufficiency. although this syndrome is rare, herein we report four cases with different clinical manifestations. they were referred to the gastrointestinal ward during a one year period with complaints of vomiting and dysphagia. the diagnosis of...

The mechanisms regulating cortisol production when ACTH of pituitary origin is suppressed in primary adrenal causes of Cushing's syndrome (CS) include diverse genetic and molecular mechanisms. These can lead either to constitutive activation of the cAMP system and steroidogenesis or to its regulation exerted by the aberrant adrenal expression of several hormone receptors, particularly G-protein...

Extra-adrenal pheochromocytomas are rare tumors that originate from the chromaffin tissue of the sympathetic nervous system. Ovarian extra-adrenal pheochromocytoma is even more rare. The present study reports a rare case of an extra-adrenal pheochromocytoma that was localized to the right ovary, but was gynecologically asymptomatic. Computed tomography angiography (CTA) detected the tumor and i...
