The angiotensin I-converting enzyme (ACE) converts the inactive angiotensin I molecule to the active angiotensin II. ACE is rich in epithelium, endothelium, and neuroepithelial cells and it found largely on the brush border of intestine and kidney proximal tubules. ACE also presents in the serum. Some pulmonary and renal toxic drugs change the serum and tissue ACE contents. In this research ACE...

Objective(s):The purpose of the present study was to investigate the protective effect of oxytocin on cisplatin (CP)-induced renal damage in rats. Materials and Methods: Fourteen adult Sprague Dawley rats, weighing 200 to 210, were administered by cisplatin (CP, 2 mg/kg/day) twice a week for five weeks. Then, they were randomly divided into two groups and treated with either saline (1 ml/kg/day...

the correlation of vesicoureteral reflux (vur), urinary tract infection (uti) and renal scarring is well known. several risk factors for renal parenchymal lesions have been reported previously. we determine the incidence of renal parenchymal damage and outcome in the siblings of children with primary vur. a total of 96 siblings of patients with vur, were evaluated with direct voiding cystograph...

Clinical data showed consumption of buckwheat played a very positive role in the relief of diabetes and its complications. The purpose of this study was to explore the effects and mechanisms of the overall flavonoids from buckwheat flowers and leaves (TFBFL) on renal damage in type 2 diabetes mellitus (T2DM) rats. Seventy male Wistar rats were selected. Ten rats were randomly allocated into a n...

Reactive oxygen species (ROS) are elevated in humans with hypertension many of which develop end-stage renal disease (ESRD), and antioxidant capacity is decreased. About one-half of essential hypertensives have a salt-sensitive type of hypertension, and the amount of renal damage that occurs in salt-sensitive hypertensives greatly exceeds that of non-salt-sensitive hypertensives. Antioxidant th...

abstract background: screening for patients at risk of renal scarring is a challenge in children with acute pyelonephritis (apn). diuretic tc-99m mercaptoacetyltriglycine (mag3) scintigraphy with zero time injection of furosemide (mag3-f0) was observed to display focal parenchymal disorders. the advantages of mag3 include: lower radiation dose and short duration of the test. the aim of this stu...

background: previous studies have shown increases in endothelin (et) concentration of plasma and renal tissues in acute renal failure (arf).  et has a potent vasoconstrictor effect, through binding with its et a receptors, and may play some roles in renal hemodynamic dysfunction in arf. objective: to examine the beneficial effect of a selective et a -receptor antagonist on renal dysfunction and...
