A case of 49-year-old woman with a retroperitoneal undifferentiated foregut cyst attached to the right adrenal gland is reported. The bronchogenic cyst is a type of foregut cyst with a cartilage component, but in this case the multicystic tumor lacked both cartilage and gland. It is quite rare among retroperitoneal tumors and has not been reported so far to have malignant potential. The preoper...

The morphological and stereological structure of rat adrenal gland was analysed by light microscopy after an acute (60 min) exposure to high ambient temperature (38 degrees C). A significant increase in plasma corticotrophin (ACTH) and serum corticosterone (CORT) concentrations was observed, confirming that acute heat exposure has a strong stressful effect. Under these conditions the adrenal gl...

OBJECTIVES Cold exposure induces glycogen and lipid depletion in the liver and the adrenal gland, respectively. However, no previous study has determined the effects of electrical countershock on those tissues. We aimed to evaluate the effects of electrical countershock on lipid depletion in the adrenal gland and on glycogen depletion in the liver. METHODS We used 40 male Wistar rats divided ...

Functioning adrenal adenomas are well-described entities that can rarely occur outside the adrenal gland in the ectopic adrenal tissue. Similarly, myelolipoma is an another benign lesion of the adrenal tissue which can rarely occur outside the adrenal gland. We report the first case of a testosterone producing an extra-adrenal adrenocortical oncocytoma accompanied by a myelolipoma. The patient ...

background although neuregulin-1 （nrg1）and its receptors have been indicated at the mrna level in partial human endocrine organs and its functional roles have been evaluated in vitro, their morphological distribution in higher animals are not fully studied. the present research focused on expression of nrg1 and its main receptors erbb2 and erbb4 in main endocrine organs of the rhesus monkey. ma...

The current Coronavirus disease outbreak requires that physicians work in collaboration with other especially intensive care and emergency units. To fight against this new disease, whose pathogenesis, effects, results have not been clearly demonstrated, patients the pre-existing chronic special expertise perspectives. Due to need for dynamic glucocorticoid treatment at different stages of adren...

In mammals, circadian rhythms of various organs and tissues are synchronized by pacemaker neurons in the suprachiasmatic nucleus (SCN) of the hypothalamus. Glucocorticoids released from the adrenal glands can synchronize circadian rhythms in other tissues. Many hormones show circadian rhythms in their plasma concentrations; however, whether organs outside the SCN can serve as master synchronize...

extra-skeletal ewing’s sarcoma is a rare soft tissue malignant neoplasm, morphologically indistinguishable from skeletal ewing’s sarcoma. the usual sites of involvement are the soft tissues of para-vertebral region, chest wall, and lower extremity. extra-skeletal ewing’s sarcoma is rare in the head and neck region and very few cases are reported in the parotid gland. the cytological features of...

The renin-angiotensin (ANG) system has been implicated in the development of hypertension in spontaneously hypertensive rats (SHR). Because SHR are more susceptible to stress than normotensive Wistar-Kyoto rats (WKY), we measured the mRNA expression of AT1A, AT1B, and AT2 receptors in the hypothalamo-pituitary-adrenal (stress) axis of male SHR in comparison to age-matched WKY at prehypertensive...

Adenoid cystic carcinoma is a rare malignant neoplasm of the salivary gland. Salivary gland neoplasms constitute 3% cancers all sites, which, 10–15% are malignant. Though adenoid most common tumor submandibular, sublingual and minor glands, it accounts for only 15% parotid cancers. They generally slow-growing spread relentlessly to adjacent structures. Hematogenous more than lymphatic spread, s...
