1-Objective:- Polyphenols are biochemical compounds with antioxidant activity against differences diseases related to Lipid peroxidation such as diabetes mellitus. Polyphenols distributed widely in medical plants, the aim of the study is to extract and analyze some polyphenolic compounds from grape seeds and examine their effects on (STZ) induced diabetic mice. 2-Methods:- In the present study , a group of polyphenols has been extracted from Iraqi grape seeds by ethanol and the extract has been analyzed by using High Performance Liquid Chromatography (HPLC) coupled to ultra violet (UV) detection. Five fractions were eluted from the column : procyanidin B1, gallic acid , quercetin , catechin and epicatechin. The detection was recorded at (280 nm). The reactive action of the above polyphenols on glucose, and malondialdehyde (MDA) levels and glutathione – S – transferase (GST) activity was tested in (30) streptozotocin (STZ) induced diabetic mice which treated with extracted grape seeds polyphenols to examine the antioxidant effect of these compounds . Grape seeds polyphenols action on the above parameters was determined before treatment and after (1 week), ( 2 weeks) and (3 weeks) of treatment with this reactive extract. 3-Results:- The data have shown that glucose levels were increased in (30) diabetic mice (after injection with streptozotocin) compared with control group (p<0.001) but after treatment with grape seeds polyphenols , glucose levels were decreased relatively (p<0.001) after (1 week), (p<0.001) after (2 weeks) and (p<0.01) after (3 weeks) of treatment with these polyphenolic compounds. MDA levels were increased for diabetic mice (after injection with streptozotocin) compared with control group (p<0.001) but after treatment with grape seeds polyphenols , MDA levels were decreased relatively (p<0.01) after (1 week) ,(p<0.01) after (2 weeks) and (p<0.05) after (3 weeks) of treatment. GST activity was increased in diabetic mice (after injection with streptozotocin ) compared with control group (p<0.001) but after treatment with grape seeds polyphenols , GST activity was decreased relatively (p<0.01) after (1 week), (p<0.01) after (2 weeks) an (p<0.05) after (3 weeks)of treatment with these antioxidant compounds. 4-Conclusion:- Our data indicated that glucose , MDA levels and GST activity correlated positively with oxidative stress related to diabetes mellitus.
Abstract The dissemination of knowledge is no longer confined to schools and universities, not even books. For nearly two centuries, the media have become prominent in disseminating knowledge and culture, in its public and particularly political aspects. After the development of the media from newspapers and magazines to the visual media, their role has increased from the dissemination of abstract information and abstract knowledge towards the process of forming new knowledge through what it publishes and broadcasts from different programs such as drama, news and talk shows. The impact of the media has changed the overall community awareness. Half a century ago the media was not so powerful and widespread. The evolution of the 1990s made

Anadrol (oxymetholone) is an active androgenic anabolic steroid that has been clinically studied in numerous diseases since the 1960s. It is used in the treatment of anemia and the replacement of male sex steroids. Unfortunately, in attempts to improve physical performance, Anadrol could be misused by athletes, that can lead to poisoning contributes to hepatotoxicity.
The aim of this study was to investigate the impact of anadrol on the liver function in rat model, via assessment of liver enzymes and histopathological study.
A forty male rats, weights about (200-300 gm), aged 8-12 weeks, after acclimatization, the rats were randomly divided into four groups (10 rats in each group) as follow: control group (in w

At the present time there are no sufficient evidences of positive effect of these medications on bone coming from randomized controlled trials; knowledge of additional effects of those drugs on the bone metabolism will allow doctors to choose optimal treatment of hypertension, taking into account the state of bone tissue. At the same time it will also allow to prevent osteoporosis in patients having osteoporosis risk factors or initial signs of bone loss.

Effective attentional control can enhance an athlete’s ability to react to dynamic game situations. The nomination of ideas strategy. Objective: This study aims to examine the effectiveness of the nomination of ideas strategy in enhancing divided and selective attention and its subsequent impact on volleyball skill performance. Methodology: A controlled experimental design was employed, involving volleyball players divided into an experimental group and a control group. The experimental group integrated the nomination of ideas strategy into their training sessions,

The experiments were conducted in a factorial experiment under complete randomized design with three replications. The results showed that the PS of 2.483 km.hr-1 was significantly better than the PS of 4.011km.hr-1 in all studied conditions.

Show MoreThe liver protective effects of pentoxifylline were studied through pre-treatment of rats with various intraperitoneal (IP) doses (25, 50 and 100mg/kg/day) 14 days before induction of liver toxicity by carbon tetrachloride (CCl4). The parameters of oxidative stress, malondialdehyde (MDA) and reduced glutathione (GSH) were measured in liver homogenate in addition to histopathological examinations. Analysis of data revealed significant amelioration of oxidative stress in groups of animals pre-treated with different doses of pentoxifylline (PTX) compared to group of animals intoxicated by CCl4 as evidenced by lowering MDA contents and elevation of GSH levels in liver tissue homogenate but the levels still signifi
