Article: Opuntia ficus indica f. inermis fruit juice alleviates ethanol-induced kidney injury in rats
[show abstract] [hide abstract]
ABSTRACT: The present work studied the protective effect of Opuntia ficus indica f. inermis fruit juice (OFIJ) against ethanol-induced renal dysfunction in rats. Chronic ethanol administration (3 g/kg b.w) during 12 weeks to Wistar rats, significantly (p < 0.01) increased the serum and kidney malondialdehyde (MDA), the serum contents of urea, creatinine, gamma glutamyl transferase (GGT) and the urinary glucose and protein levels. Whereas, copious ethanol intoxication significantly (p < 0.01) decreased the vitamin E and C levels in serum and kidney tissue as well as the glutathione content (GSH) and the activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px) and caused a severe renal histological injuries. Rivalry pre-treatment of ethanol-fed rats with OFIJ (20 and 40 ml/kg b.w., orally), interestingly attenuated the increases in serum and kidney MDA, and enhanced the antioxidant status of the rats by increasing the levels of SOD, CAT, (GSH-Px), GSH and vitamins. The biochemical findings positively corroborate with the amelioration of kidney histological morphology. The results suggest that the renal protective effect of Opuntia ficus indica f. inermis fruit juice (OFIJ) is by attenuating oxidative stress induced by copious ethanol supplement.Asian Journal of Biomedical and Pharmaceutical Sciences. 05/2013; 3(19):15-21. -
Article: Phytochemical, antioxidant and protective effect of Rhus tripartitum root bark extract against ethanol-induced ulcer in rats.
[show abstract] [hide abstract]
ABSTRACT: Rhus tripartitum (sumac) is an Anacardiaceae tree with a wide phytotherapeutic application including the use of its roots in the management of gastric ulcer. In the present study the Rhus tripartitum root barks extract (RTE) was phytochemical studied, in vitro tested for their potential antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and reducing power assay and in vivo evaluated for its ability to prevent ethanol-induced gastric ulcer in rats. The RTE was rich in phenolics, flavonoids, tannins and polysaccharide contents and exhibited a low but not weak in vitro antioxidant activity when compared with (+)-catechin. Pre-treatment with RTE at oral doses 50, 200 and 400 mg/kg body weight was found to provide a dose-dependent protection against ethanol-induced ulcer by averting the deep ulcer lesions of the gastric epithelium, by reducing gastric juice and acid output, by enhancing gastric mucus production by preserving normal antioxidant enzymes activities, and inhibiting the lipid peroxidation. The antiulcerogenic activity of RTE might be due to a possible synergistic antioxidant and antisecretory effects.General Physiology and Biophysics 03/2013; 32(1):115-27. · 1.19 Impact Factor -
Article: Evaluation of Opuntia ficus indica f. inermis fruit juice hepatoprotective effect upon ethanol toxicity in rats.
[show abstract] [hide abstract]
ABSTRACT: The aim of our present study is to investigate the effect of Opuntia ficus indica f. inermis prickly pear juice (PPJ) against ethanol-induced liver injury in rats. Chronic ethanol administration (3 g/kg b.w.) during 90 days to Wistar rats, significantly (p < 0.01) increased the liver lipid and protein oxidation, reduced the glutathione content and the activities of liver antioxidant enzymes such as superoxide dismutase, catalase, glutathione peroxidase and conversely elevated the liver injury biochemical markers like aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, gamma glutamyl transferase, lactate dehydrogenase, cholesterol, triglycerides and caused a severe histopathologic injuries. Conversely pre-treatment of ethanol-fed rats with PPJ (20 and 40 ml/kg b.w., orally), interestingly reduced liver lipid and protein oxidation, histopathologic lesions and inhibited the alterations of antioxidant enzymes and the release of biochemical markers. The hepatoprotective effect of PPJ could be due to their capacity to end free radicals chain reactions or to enhance the endogenous antioxidants activities.General Physiology and Biophysics 09/2012; 31(3):335-42. · 1.19 Impact Factor -
Article: Protective effect of Opuntia ficus indica f. inermis prickly pear juice upon ethanol-induced damages in rat erythrocytes.
[show abstract] [hide abstract]
ABSTRACT: Juice from the fruit of the cactus Opuntia ficus indica is claimed to possess several health-beneficial properties. The present study was carried out to determine whether O. ficus indica f. inermis fruit extract might have a protective effect upon physiological and morphological damages inflicted to erythrocytes membrane by chronic ethanol poisoning, per os, in rat. Chemical analysis of the extract revealed the presence of polyphenols, flavonoids, ascorbic acid, carotenoids, and betalains. Ethanol administration (3 g/kg b.w, per day for 90 days) induced an increase of malondialdehyde (MDA) and carbonylated proteins levels and a decrease of glutathione (GSH) level in erythrocyte. Ethanol administration also reduced the scavenging activity in plasma and enhanced erythrocytes hemolysis, as compared to control rats. In addition, ethanol intake increased the erythrocyte shape index by +895.5% and decreased the erythrocyte diameter by -61.53% as compared to controls. In animals also given prickly pear juice during the same experimental period, the studied parameters were much less shifted. This protective effect was found to be dose-dependent. It is likely that the beneficial effect of the extract is due to the high content of antioxidant compounds.Alcohol (Fayetteville, N.Y.) 03/2012; 46(3):235-43. · 2.41 Impact Factor -
Article: Ameliorative effect of Opuntia ficus indica juice on ethanol-induced oxidative stress in rat erythrocytes.
[show abstract] [hide abstract]
ABSTRACT: The aim of the present study was to investigate the efficacy of Opuntia ficus indica f. inermis fruit juice (OFIj) on reversing oxidative damages induced by chronic ethanol intake in rat erythrocytes. OFIj was firstly analyzed with HPLC for phenolic and flavonoids content. Secondly, 40 adult male Wistar rats were equally divided into five groups and treated for 90 days as follows: control (C), ethanol-only 3g/kg body weight (b.w) (E), low dose of OFIj 2ml/100g b.w+ethanol (Ldj+E), high dose of OFIj 4ml/100g b.w+ethanol (Hdj+E), and only a high dose of OFIj 4ml/100g b.w (Hdj). HPLC analysis indicated high concentrations of phenolic acids and flavonoids in OFIj. Ethanol treatment markedly decreased the activities of erythrocyte superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px), and the level of reduced glutathione (GSH). Changes in the erythrocyte's antioxidant ability were accompanied by enhanced oxidative modification of lipids (increase of malondialdeyde level) and proteins (increase in carbonyl groups). Interestingly, pre-administration of either 2ml/100g b.w or 4ml/100g b.w of OFIj to ethanol-intoxicated rats significantly reversed decreases in enzymatic as well as non enzymatic antioxidants parameters in erythrocytes. Also, the administration of OFIj significantly protected lipids and proteins against ethanol-induced oxidative modifications in rat erythrocytes. The beneficial effect of OFIj can result from the inhibition of ethanol-induced free radicals chain reactions in rat erythrocytes or from the enhancement of the endogenous antioxidants activities.Experimental and toxicologic pathology: official journal of the Gesellschaft fur Toxikologische Pathologie 01/2012; · 1.43 Impact Factor
