Background: The aim of this study was to evaluate the possible protective effect of sodium selenite on serum, liver, and kidney antioxidant enzymes activities in alloxan-induced type 1 diabetic rats. Methods: Forty Sprague-Dawley male rats were randomly divided into four groups; Group one as control, Group two as sham-treated with sodium selenite by 1 mg/kg intraperitoneal (i.p.) injections ...

During sepsis, the alarmin HMGB1 is released from tissues and promotes systemic inflammation that results in multi-organ damage, with the kidney particularly susceptible to injury. The severity of inflammation and pro-damage signaling mediated by HMGB1 appears to be dependent on the alarmin's redox state. Therefore, we examined HMGB1 redox in kidney cells during sepsis. Using intravital microsc...

The toxic effects of paraquat on the anti-oxidant defense system of male albino rats were evaluated, after administering either a single dose (1.5 and 7.5 mg/kg of body weight) or continuous daily doses (same as above, i.e., 1.5 mg/kg and 7.5 mg/kg of body weight) for 3 and 7 days. Glutathione levels in blood cells, liver, lung and kidney tissues decreased in a dose and time dependent manner. G...

background: the pathogenesis of ethanol in the liver and kidney is associated with an increase in free radicals and oxidative stress that leads to structural and functional abnormalities in these vital organs. methods: forty-eight male wistar rats were placed in eight groups and were treated as follows: control group (normal saline), group of ethanol (4 g/ kg), three doses of ardeh and honey co...

Liver homogenates could synthetize S-(isopropylcarboxymethyl) glutathione (GSIV) from isovaleric acid and glutathione, and GSIV thus formed was cleaved into L-allo-isovalthine by kidney glutathionase preparation. Isovaleric acid-l-C14 incorporated into GSIV without prior cleavage by the in vitro system. The discrepancy of configuration between urinary and in vitro synthesized isovalthine was di...

Objective: The present study was conducted to determine the hypoglycemic and antioxidant potential of polyherbal formulation in alloxan induced diabetic rats. Study Design: In five different groups an aqueous suspension of herbal mixture containing equal amounts of– Azadirachta indica, Gymnema sylvestre, Momordica charantia, Syzigium cumini, Trigonella foenum was administered orally once a day ...

The radioprotective effects of Liv.52 on tissue-reduced glutathione (GSH) levels were studied in rats. Adult female Sprague Dawley rats were exposed to whole body gamma radiation of 4 Gy and 8 Gy. Prior to radiation exposure, Liv.52 was fed, one ml per rat, daily for 15 days. Three days after radiation exposure, reduced glutathione levels in the liver, spleen, kidney and blood were studied.

introduction: the impact of chromium exposure was studied on liver, kidney, testis, spleen, cerebrum and cerebellum of male wistar rats (80-100 g body weight). material & method: it was observed that treatments of rats with chromium (i.p. at a dose of 0.8 mg / 100 g body weight per day) for a period of 28 days caused significant increase in chromium content while declining the body weight along...

background & aim: mammea africana sabine (guttiferae) stembark commonly used traditionally to treat various diseases and ailments was evaluated for nephroprotective activity against paracetamol – induced kidney injury in rats to confirm its use in the treatment of kidney diseases. experimental:  the nephroprotective effect of the extract was evaluated by the determination of some kidney fun...

Chronic renal failure (CRF) is associated with oxidative stress, the precise mechanism of which is yet to be elucidated. The present study was undertaken to investigate in renal insufficiency the expression of catalase and glutathione peroxidase, which play a critical role in antioxidant defense system by catalyzing detoxification of hydrogen peroxide (H2O2) and organic hydroperoxides. Rats wer...
