Abstract:

Diazinon is an organophosphate which is extensively used in trade and agriculture. Due to its widespread application, its toxicity is common. Several studies have shown that organophosphates are able to induce oxidative stress by generating free radicals and depletion of endogenous antioxidants. Pomegranate seed oil (PSO) possesses anti-inflammatory and antioxidant effects. In this study, the effect of PSO was evaluated on diazinon-induced nephrotoxicity in rat. Wistar male rats were randomly divided into four groups, 6 each. Group one received saline, 1 mL/kg, group 2 received diazinon 100 mg/kg. Groups 3 and 4 received PSO, 0.32 and 0.64 mg/kg, one hour before diazinon 100 mg/kg respectively. After 24 h, animals were anesthetized. Blood samples were taken out by cardiac puncture for measuring the level of serum urea and creatinine. 24 h urine samples were also collected for measuring glucose and protein concentration. The right kidney was removed and homogenized for measuring malondialdehyde and thiol content Compare to control group, DIZ increased urea and serum creatinine, urinary glucose, and malondialdehyde, but did not modify significantly urinary protein and thiol content. In groups received PSO+ DIZ, serum creatinine, urinary glucose and MDA were significantly decreased. DIZ induced acute nephrotoxicity and oxidative stress. Probably, increasing of serum creatinine and urinary glucose are appropriate markers for diagnosis of kidney damage. In addition increasing of MDA level emphasizes that DIZ plays role in pathogenesis of kidney via oxidative stress mechanism. PSO reduced DIZ toxicity by antioxidant activity.

Protective effect of resveratrol against sub-acute diazinon-induced oxidative stress in rat kidney

Introduction: Diazinon is used as an organophosphate pesticide in agriculture. Studies showed that a lot of organophosphates can produce free radicals and disrupt antioxidant system. Resveratrol as an antioxidant can reduce oxidative stress in kidney tissue. The study aimed to investigate the protective role of resveratrol on oxidative stress induced by sub-acute diazinon exposure in kidney tis...

Protective Effect of Pomegranate Seed Oil against Mercuric Chloride-induced Hepatotoxicity in Rat

Mercuric chloride (HgCl2) is an environmental and industrial toxicant that affects many tissues. Considering oxidative stress is an important component of mercury induced hepatotoxicity, antioxidants are expected to play a protective role against it. The present study was designed to investigate the probable effects of pomegranate seed oil (PSO) on hepatotoxicity induced by HgCl2 administration...

Protective effect of pomegranate seed oil against H2O2 -induced oxidative stress in cardiomyocytes

Objective: It has been well documented that oxidative stress is involved in the pathogenesis of cardiac diseases. Previous studies have shown that pomegranate seed oil (PSO) has antioxidant properties. This study was designed to investigate probable protective effects of PSO against hydrogen peroxide (H2O2)-induced damage in H9c2 cardiomyocytes.Materials and Methods: The cells were pretreated 2...
