Resveratrol reduces light and electron microscopic changes in acetaminophen-induced hepatotoxicity in rats: Role of iNOS expression.

Introduction: Hepatotoxicity is a major complication of acetaminophen (APAP), a widely used analgesic and antipyretic drug. Resveratrol (RSV) is a naturally occurring diphenol and it has anticancer, antioxidant, and anti-inflammatory properties.

Objectives: In this study, the beneficial effects of RSV on APAP-induced hepatotoxicity was investigated in rats.

Introduction: In the current study, the protective effect of hesperidin (HP) on carbon tetrachloride (CCl4)-induced hepatotoxicity in rats was investigated.

Material And Methods: Twenty-eight rats were divided equally into four groups. The first group was kept as a control and given only vehicle.

Histopathological, Ultrastructural and Apoptotic Changes in Diabetic Rat Placenta.

Background: The exchange of substances between mother and fetus via the placenta plays a vital role during development. A number of developmental disorders in the fetus and placenta are observed during diabetic pregnancies. Diabetes, together with placental apoptosis, can lead to developmental and functional disorders.

Anti-inflammatory Montelukast prevents toxic effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin: Oxidative stress, histological alterations in liver, and serum cytokine levels.

This study aimed to investigate the potential beneficial effects of the montelukast (ML) on oxidative stress and histological alterations in liver tissues and cytokine levels in rats intoxicated with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). Rats were divided randomly into four equal groups (control, TCDD, ML, TCDD + ML). TCDD were administered by gavages dissolved in corn oil at the doses of 2 µg/kg/week, and ML was given intraperitoneally at the dose of 10 mg/kg/day.

Histological and biochemical effects of dexmedetomidine on liver during an inflammatory bowel disease.

Inflammation in the liver is an extraintestinal manifestation that is frequently seen during inflammatory bowel diseases (IBD). The authors investigated histopathologycal, ultrastructural and antioxidant effects of dexmedetomidine (Dex) on liver during trinitrobenzene sulfonic acid (TNBS)-induced inflammatory bowel disease. Thirty-two BALB/c mice were divided (n = 8) as follows: control; Dex (dexmedetomidine) (30 μg/kg) for 6 days; TNBS 150 μL, TNBS + ethanol (50% w/v) intrarectally; TNBS + Dex.

The protective effects of Prunus armeniaca L (apricot) against methotrexate-induced oxidative damage and apoptosis in rat kidney.

This study was conducted to evaluate a possible protective role of apricot in apoptotic cell death induced by methotrexate (MTX) and renal damage by different histological and biochemical parameters. Twenty-eight rats were divided into four groups, control, apricot, methotrexate, and apricot + methotrexate. Methotrexate induced renal failure, as shown by significant serum creatinine and urea elevation.

Prunus armeniaca L (apricot) protects rat testes from detrimental effects of low-dose x-rays.

Exposure to low x-ray doses damages the spermatozoa, mainly by late-onset (ie, after 3 months) oxidative stress. Antioxidants ameliorate oxidation and prevent tissue damage. Prunus armeniaca L (apricot), rich in carotenoids and vitamins, is a potent natural antioxidant.

Protective effect of apricot (Prunus armeniaca L.) on hepatic steatosis and damage induced by carbon tetrachloride in Wistar rats.

The present study was planned to investigate the protective effect of 10 % and 20 % apricot-containing feed on carbon tetrachloride (CCl4)-induced hepatic steatosis and damage. Adult male Wistar rats (n 42) were divided into six groups of seven each, as follows: control group; CCl4 group; CCl4+10 % apricot group; CCl4+20 % apricot group; 10 % apricot group; 20 % apricot group. All apricot groups were fed with 10 % or 20 % apricot-containing feed for 5 months.

Apricot ameliorates alcohol induced testicular damage in rat model.

In this study, we intended to determine the possible preventive effects of dietary apricot on oxidative stress due to ethanol usage in rat testes. The animals were divided into six groups as follows: Group 1 was control. Group 2 received ethanol.

The effect of resveratrol in tracheal tissue of rats exposed to cigarette smoke.

Objective: The aim of this study was to evaluate the effect of resveratrol on the tracheal tissue of rats exposed to cigarette smoke.

Materials And Methods: 40 adult Wistar albino rats were divided into four groups for an experiment of 6 weeks. Animals in group 1 were controls (n = 10).

Beneficial effects of apricot-feeding on myocardial ischemia-reperfusion injury in rats.

The present study was undertaken to evaluate the cardio-protective potential of apricot-feeding in the ischemia-reperfusion (I/R) model of rats in vivo. Rats were divided into three groups of 12 rats each. Group 1 was fed with a standard rat chow, groups 2 and 3 were fed with a standard rat chow supplemented with 10% or 20% dried apricot during 3 months before the beginning of I/R studies.

Antiapoptotic and antioxidant effects of beta-carotene against methotrexate-induced testicular injury.

Objective: To investigate the effect of beta-carotene against testicular injury induced by methotrexate (MTX).

Design: Experimental study.

Setting: Animal and histology laboratory at Inonu University.

The beneficial effects of pentoxifylline on caerulein-induced acute pancreatitis in rats.

In this study we aimed to investigate the effect of pentoxifylline on caerulein-induced acute pancreatitis (AP) by detecting oxidative stress markers and performing histopathological examination. Twenty-one adult female Sprague-Dawley rats were divided into three groups as follows: control, caerulein, and caerulein + pentoxifylline groups. Pancreatic tissues of rats from all groups were removed for light and electron microscopic examination and determination of oxidative stress markers.

Potent protective effect of apricot and beta-carotene on methotrexate-induced intestinal oxidative damage in rats.

Several studies have well confirmed the contribution of oxidative stress in the pathogenesis of methotrexate (MTX)-induced damage in the small intestine. Many agents have been tried experimentally to reduce or inhibit the oxidative stress. To our knowledge, there is no study about apricot consumption on the MTX-induced damage in the small intestine.

Oral L-arginine protects against cyclosporine-induced hepatotoxicity in rats.

Cyclosporine A (CyA) leads to liver injury, probably by causing the production of free radicals and resulting in nitric oxide (NO) deficiency. We evaluated CyA-mediated liver damage histopathologically to determine the possible beneficial effects of L-arginine (L-Arg). In this study, 7 groups of Sprague-Dawley rats; (1) Control group; (2) 0.
