25. Effects of stress on catecholamine stores in central and peripheral tissues of long-term socially isolated rats
Both the peripheral sympatho-adrenomedullary and central catecholaminergic systems are activated by various psycho-social and physical stressors. Catecholamine stores in the hypothalamus, hippocampus, adrenal glands, and heart auricles of long-term socially isolated (21 days) and control 3-month-old male Wistar rats, as well as their response to immobilizati

26. Diagnostic and therapeutic approach in adrenal masses clinically silent: review of the literature / "Diagnóstico e tratamento das massas adrenais clinicamente silenciosas: revisão de literatura"
Introduction: Clinically silent adrenal masses, incidentally diagnosed during imaging methods performed for other clinical conditions (incidentalomas) have been more frequently detected due to the constant improvement in imaging methods. There are several causes, diagnoses and treatments for these masses. Thus, whenever a physician comes across such lesi

27. "Estudo duplo-cego comparativo entre prednisona e dexametasona na avaliação da reserva adrenal em crianças e adolescentes com leucemia linfocítica aguda" / Evaluation of adrenal reserve in children and adolescents with acute lymphocytic leukemia through a double-blind comparison between Prednisone and Dexamethasone
Para avaliar a reserva adrenal após o uso de glicocorticóide na fase de indução de remissão em pacientes com Leucemia Linfocítica Aguda, estudo duplo-cego foi realizado em 29 crianças e adolescentes de 1,7 a 15,9 anos (média:6,8 anos], que receberam por escolha aleatória, Prednisona na dose de 40 mg/m²/dia ou Dexametasona, 6 mg/m²/dia, via oral, p

28. Diazepam effects on tumor growth and on immunity of Ehrlich tumor bearing mice / Efeitos do diazepam sobre o crescimento tumoral e imunidade de animais portadores do tumor ascítico de Ehrlich
Benzodiazepines (BDZ) are drugs widely used due to their anxiolytic and sedative properties, acting on specific sites coupled to GABAA complex in the Central Nervous System (CNS). Besides these central receptors, BDZ have affinity for peripheral-type receptors (PBR), which have been found in immune cells, such as lymphocytes and macrophages, in tumor cells a

29. Role of endogenous glucocorticoids in hyperalgesia and edema in old arthritic rats
We compared the intensity and frequency of arthritis in old (8-12 months, N = 12) and juvenile (2 months, N = 10) rats and determined the role played by adrenal glands in this disorder. Arthritis was induced by subcutaneous injection of Mycobacterium butyricum at the base of the tail of female Holtzman rats at day zero. Paw edema and hyperalgesia were monito

30. Estudo da função das glandulas supra-renais em pacientes asmaticos em uso de beclometasona e fluticasona
Bronchial asthma is widely known as a chronic inflammatory disease of the airways and corticosteroids are the most effective drugs for asthma treatment since they block many of the inflammatory mechanisms of the disease and they have prophylactic action. In the last decades, with the introduction of inhaled corticotherapy, there was a reduction in the period

31. Clonagem do Receptor de ACTH de células adrenocorticais Y-1 de camundongo e expressão em fibroblastos 3T3 e células de AR-1 para elucidação de vias de transdução de sinal / Cloning of ACTH receptor from mouse Y1 adrenocortical cells and expression in to mouse 3T3 fibroblasts and AR-1 cells for the study of signal transduction pathways.
The adrenocorticotropic hormone, ACTH, regulates both function and proliferation of adrenocortical cells binding to a specific receptor, ACTHR, which belongs to superfamily of GPCR (G-protein coupled receptors). ACTHR was cloned a few years ago, but the molecular mechanisms underlying the mitogenic and anti-mitogenic actions of ACTH remain unknown, whose elu

32. Biosynthesis and metabolism of steroid hormones by human adrenal carcinomas
Over a 15-year period, our university-based laboratory obtained 125 adrenal tumors, of which 15 (12%) were adrenal cortical carcinomas. Of these, 6 (40% of the carcinomas) occurred in patients with clear clinical manifestations of steroid hormone excess. Adrenal cortical carcinoma cells derived from the surgically resected tumors in 4 of these patients were

33. Estudo dos efeitos do diabetes induzido por estreptozotocina sobre as glandulas supra-renais e testiculos de camundongos
ln the present study, morphometrical and morphological (histological and ultrastructural) parameters of the adrenal and testicle glands of mice treated with estreptozotocin (STZ) were evaluated. Sixteen male mice, with 90 days, were divided in the following experimental groups: Group 1 - control; Group II - diabetic. During the treatment, weekly tests of uri

34. Expression of p21(WAF1/CIP1/SDI1) and p53 in apoptotic cells in the adrenal cortex and induction by ischemia/reperfusion injury.
p21(WAF1/CIP1/SDI1), an inhibitor of cyclin-dependent kinases, is expressed at varying levels in human adrenal glands removed during surgery or organ recovery. In glands with p21 mRNA, nuclear p21 immunoreactivity, which was occasionally extensive, colocalized with p53 immunoreactivity and DNA damage, as evidenced by in situ end-labeling. Many cells showed m

35. Release of enkephalins and enkephalin-containing polypeptides from perfused beef adrenal glands.
Enkephalins and enkephalin-containing polypeptides were released from perfused bovine adrenal glands by nicotine and Ba2+, agents that release catecholamines. All the enkephalin-containing polypeptides that are normally found in the adrenal medulla were released by the two secretagogues in approximately the same proportions as are present in adrenal chromaff

36. A simple technique for identifying the adrenal glands at necropsy.
There is no detailed and practical description of how to identify the adrenal glands at necropsy. A simple technique is described, based on anatomical location. After removing the aorta by the Rokitansky method, the inferior vena cava is opened. The orifice of the right adrenal vein is identified just above the right renal vein, and a probe is inserted into
