Abstract
This study was designed to test the effect of Korean traditional teas on lipid levels in lead (Pb)-administered rats. Male rats were divided into normal, Pb-control (rb-Con) and Pb-water extract of traditional teas (green tea: GWE, persimmon leaf: PWE, safflower seed: SWE, Solomon's seal: SSWE) groups. Pb intoxication was induced by administration lead acetate (25 mg/kg. BW, oral) weekly. The extract was administered based on 1.26 g of raw traditional tea/g BWday for 4 weeks. Net weight gain and feed intake were significantly lower in the Pb-Con group than in the normal group, whereas they were tended to increase by traditional teas supplements. Both Plasma and hepatic total cholesterol and triglyceride concentration were lower in the traditional teas supplemented groups compared to the Pb-Con group. Plasma VLDL-cholesterol and LDL-cholesterol levels were significantly increased by Pb ad-ministration, whereas HDL-cholesterol concentration was significantly lower in the Pb-Con group than in the normal group. However, water extracts of green tea, persimmon leaf, safflower seed and solomon's seal supplementation improved changes of the plasma lipoprotein-cholesterol levels in Pb administered rats.
