introduction: complete androgen insensitivity syndrome (previously called testicular feminization) is specified by a 46 xy karyotype and negative sex chromatin, bilateral undescended testes, female genitalia appearance, and lack of mullerian derivatives. discussion: our medline search revealed that this is the first reported case of bilateral sertoli–leydig cell tumor (slct) in androgen insensi...

desmoplastic small round cell tumor (dscrt) is a rare variant of sarcoma with a highly aggressive behavior. it usually affects abdominal cavity and has a male predominance. its correct diagnosis and treatment is sophisticated and requires an experienced multidisciplinary team. hereby we present a 25 yrold man from kerman province in 2013 with abdominal mass and ascites who underwent sonograghy ...

Bartter's Syndrome is characterized by renal potassium wasting with hypokalemia, metabolic alkalosis, increased renin-angiotensin-aldosterone system, normal blood pressure, resistance to the pressor effects of angiotensin II and juxtaglomerular cell hyperplasia. Most of the cases have been noted in the pediatric age group and adult-onset cases are very rare. We report a case of adult-onset Bart...

Macrophages have been identified in mouse kidney by immunohistochemical localization of the macrophage-specific antigen F4/80. They constitute the majority of the renal medullary interstitial cell population and are also found in contact with cortical distal and proximal tubules and Bowman's capsule. They are a physical component of the juxtaglomerular complex.

introduction: the aim of this study was to investigate the effect of the hsp-70 (heat shock protein-70) induction in the lysate of heat shocked tumor cells on splenocyte proliferation, nitric oxide production by peritoneal macrophages, and fibrosarcoma tumor size reduction in balb/c mice. material and methods: wehi 164 cells (mouse fibrosarcoma cell line) were injected subcutaneously into the r...

The aim of the present study was to investigate the endothelial influence on renin secretion of isolated juxtaglomerular cells. Specifically the role of nitric oxide (NO) and of endothelin was studied. Coculture of primary cultures of juxtaglomerular cells with aortic and microvascular endothelial cells decreased renin secretion. Inhibition of NO formation by absence of l-arginine or presence o...

IN A SYMPOSIUM devoted to angiotensin, it is appropriate to consider briefly the juxtaglomerular apparatus. Angiotensin makes its appearance in the body as a direct result of the proteolytic action of renin, and there is considerable evidence to support the hypothesis that all the renin in a kidney comes from the juxtaalomerular apparatus. Before reviewing this evidence, the anatomy of the juxt...

background and aims: plants as medicines have always played a vital role in human life. tumor necrosis factor alpha (tnf)-α is one of the macrophage-derived inflammatory cytokine with pleotropic effects in the inflammation process. some studies have been demonstrated that some of the echinops species have anti-inflammatory activity. in fact, echinops lasilepis is introduced as one of the native...

objective: recent evidences suggest that tumors arise from a small subpopulation of cells, the cancer stem cells (cscs) or tumor initiating cells. cscs are able to resist the conventional methods of cancer therapy due to existence of abc transporters on their surface. this leads to csc resistance and maintenance resulting in post-treatment relapse and metastasis. therefore, precise identificati...
