采用脂代谢紊乱模型法—预防性给予不同地区不同剂量的红茶（剂量为成人每日饮用量的5倍、10倍和20倍 3 种），观察小鼠体重、血脂、相关酶及肝脏形态的变化。结果表明：与高脂模型对照组相比，红茶剂量组能极显著（P＜0.01）降低血清总胆固醇（TC）、低密度脂蛋白（LDL-C）、肝脏丙二醛（MDA）、肝脏指数；极显著（P＜0.01）升高血清载脂蛋白 A1（apoA1）、脂蛋白脂酶（LPL）、肝脂酶（HL）、总脂酶、肝脏超氧化物歧化酶（SOD）及谷胱甘肽过氧化物酶（GPX），血清高密度脂蛋白（HDL-C）有所上升，小鼠体重也得到了一定的抑制，肝脏病变程度得到了相应的减轻，说明红茶具有一定的调节血脂及减小肝脏因高脂饮食所带来的损伤。

The lipid metabolic disturbance model method was used to investigate the regulatory effects of Black Tea (BT) at different dosages (5 times, 10 times and 20 times of adult daily consumption) on serum lipid levels in hyperlipoidemia mice. In present study, blood lipid levels, body weight, and related enzymes of liver and serum were measured, and the histopathological changes in tissues of liver were also examined. It was found that the serum levels of total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C), liver malondialdehyde (MDA) and liver index were significantly lower (P<0.01) in BT-treated mice compared with the high hyperlipoidemia model mice, while serum levels of apoA1, lipoprotein lipase (LPL), hepatictriglyceridelipase (HL) and total lipase, and liver superoxide dismutase (SOD) actives and glutathione peroxidase (GSH-Px) actives were significantly higher after treatment with BT (P<0.01). Additionally, serum levels of high density lipoprotein cholesterol (HDL-C) was slightly increased. Moreoverr, body weight was reduced, and the liver lesions were attenuated to some degree in BT-treated mice. The results suggested that BT showed a positive effect on regulating the serum lipid and reducing the liver injury induced by high fat diet.
