Drinking alcoholic beverages recently is common in many parts of the world, liver is a principal organ that involved in toxic effects of alcohol and it remains a serious health problem globally. Fatty liver (steatosis) was induced in male albino rats by alcohol 40% orally (3.76gm/kgm BW/day) for the period of 4 weeks, then green tea extract (GTE) and omega-3 (OMG-3) fish oil were used as treatments for improvement and investigating their comparison potential role for the next 4 weeks. At the end of the experiment, the rats were fasted overnight, blood samples through the cardiac puncture and liver organ were collected for biochemical and histopathological analysis respectively. Biochemical parameters including: lipid profiles: (total cholesterol (TC), triglycerides (TG), high density lipoprotein-cholesterol (HDL-C) and low density lipoprotein-cholesterol (LDL-C), serum malondialdehyde (MDA), liver function tests (LFT): (Serum albumin (ALB), serum total protein (TP), total serum bilirubin (TSB), serum alkaline phosphatase (ALP), serum alanine aminotransferase (ALT), and serum aspartate aminotransferase (AST) and finally hepatic histological changes were also investigated. Alcoholic rats were associated with significant elevation (P<0.05) in the levels of serum TC, TG, LDL-C, MDA, TSB, ALT, AST and ALP, whereas the levels of serum HDL-C and TP significantly (P<0.05) decreased with no significant change (P>0.05) of serum ALB level. treatment of alcohol-fed rats with GTE and OMG-3 oil either alone or in their combination have significant role (P<0.05) in lowering the injury effects of alcohol evidenced by reversing the results obtained on serum lipid profiles, MDA, LFTs and hepatic histological changes after their treatments during the amelioration study. Ethanol consumption impaired hepatic functions, disturbed lipid metabolism, induced hyperlipidemia and increased oxidative stress. Aqueous extracts of GT and OMG-3 oil significantly improved alcohol-induced liver injury through improvement of serum markers of hepatic injury, their hypolipidemic actions and hepatic histologic recovery. Co-treatments of GT+OMG-3 have more protective effect or faster progression against ALD than their treatments alone.

The purpose of this study was to investigate the effect of green tea extract (GTE) supplementation combined with endurance training on endurance capacity and performance in sedentary men. Forty untrained men (age: 20 ± 1 years) participated in this study. Subjects were assigned to 1 of 4 treatments: (i) placebo-control (CTRL), (ii) GTE, (iii) endurance training (Ex), and (iv) endurance training with GTE (ExGTE). During the 4-week intervention, exercise training was prescribed as 75% oxygen uptake reserve for three 20-min sessions per week, and either GTE (250 mg/day) or placebo was provided. Endurance capacity, malondialdehyde (MDA), total antioxidant status (TAS), and creatine kinase (CK) were examined. Ex and ExGTE but not GTE improved exhaustive-run time (Ex: +8.2%, p = 0.031; ExGTE: +14.3%, p < 0.001); in addition, Ex and ExGTE significantly increased maximal oxygen uptake by ∼14% (p = 0.041) and ∼17% (p = 0.017) above the values of the CTRL group, respectively. Both Ex and ExGTE significantly decreased the increase of CK by ∼11%–32% below that of CTRL following an exhaustive run (Ex: p = 0.007; ExGTE: p = 0.001). Moreover, TAS levels increased by ∼11% in ExGTE after training (p = 0.040), and GTE, Ex, and ExGTE markedly attenuated exercise-induced MDA production (p = 0.01, p = 0.005, p = 0.011, respectively). In conclusion, this investigation demonstrated that daily ingestion of GTE during endurance training does not impair improvements in endurance capacity. Moreover, endurance training combined with GTE not only increases antioxidant capacity without attenuating endurance training adaptations, but also further attenuates acute exercise-induced CK release.
