Oxidative stress is involved in both the pathogenesis and complications of diabetes. ACE inhibitors can slow the progression of cardiac and renal impairments related to diabetes. The effect of enalapril treatment on oxidative stress and tissue injury was studied in hearts, kidneys, and livers from streptozotocin-induced diabetic rats. Twenty-four rats were divided into the following groups: str...

the present study was aimed at elucidating the protective effect of ferulic acid (fa), a natural polyphenol against nicotine-induced tissue damage, including lung, liver and kidney of experimental rats. female albino rats of wistar stain were used for the experimental study. lung toxicity was induced by subcutaneous injection of nicotine at a dose of 2.5 mg/kg body weight (5 days a week, for 22...

We evaluated the preventive effects of Terminalia chebula (T. chebula) aqueous extract on oxidative and antioxidative status in liver and kidney of aged rats compared to young albino rats. The concentrations of malondialdehyde (MDA), lipofuscin (LF), protein carbonyls (PCO), activities of xantione oxidase (XO), manganese-superoxide dismutase (MnSOD), catalase (CAT), glutathione peroxidase (GPx)...

Background: This study examined the effect of grape seed proanthocyanidin extract (GSPE) on lipid peroxidation content and activity of tissue antioxidant enzymes, including catalase, superoxide dismutase and glutathione peroxidase in diabetic rats. Methods: Thirty male rats were divided into three groups of 10 rats each: control, diabetic and diabetic groups that received 500 mg/kg GSPE for 6 w...

  Objective(s): Because of the high total phenolic contents of Feijoa sellowiana , its nephroprotective effect was determined in 3,4-methylene dioxymethamphetamine (MDMA) treated mice.   Materials and Methods: Animals received 10, 20 and 40 mg/kg doses of aqueous or methanol extract of F. sellowiana leaves, intra-peritoneally. After one hour, an acute administration of MDMA (20 mg/kg, IP)...

The present study focuses on the role of Costus pictus extract (CPE) against the oxidative stress caused by hypeglycemia in liver and kidney of alloxon administered rats.Hyperglycemic rats were administered with two dose levels(200 and 400mg/kg body weight) of CPE for 30 days.At the end of treatment,blood glucose,serum marker enzymes alanine amino transfrease(ALT),aspartate amino transferase(AS...

Background: Diabetes-related dysfunctions are the major causes of mortality and morbidity for diabetic patients. Objectives: Selenium is a potent antioxidant. In the present study, we examined antioxidative activities of sodium selenite and possible protective effect of it on serum, liver and kidney lipid peroxidation and glutathione in alloxan-induced type 1 diabetic rats. Materials and Method...

Calcium oxalate monohydrate (COM) crystals are the commonest component of kidney stones. Oxalate and COM crystals in renal cells are thought to contribute to pathology via prooxidant events. Using an in vivo rat model of crystalluria induced by hyperoxaluria plus hypercalciuria [ethylene glycol (EG) plus 1,25-dihydroxycholecalciferol (DHC)], we measured glutathione and energy homeostasis of kid...

Changes in functional activities of mitochondria from kidney cortical slices incubated with cisplatin and the glutathione depletor diethylmaleate were examined. Diethylmaleate, which decreased the glutathione level in the slices, enhanced the cisplatin-induced decreases in glutathione level and calcium uptake in the mitochondria. The movement of cisplatin into mitochondria in the slices was not...
