ABSTRACT
Objective To explore the effects of zinc selenium tea (ZST) on glucose and lipid metabolism.Methods Rats were divided into groups C,CH,CHT and ZTH.After being fed on high-fat,high-sugar diets for seven weeks,group ZTH was irrigated with ZST for eleven weeks,while group CHT was irrigated with green tea.FBG was measured weekly.Levels of blood glucose and lipid were detected.Results FBG at 45,60,or 120 min was lower in ZTH than in CHT in week 12 (P ＜ 0.01).In the 6th and 1 lth week,level of FBG was in group CHT ＞ CH ＞ ZTH ＞ C.FBG in week 11 was lower in group ZTH than in group CHT (P ＜ 0.05).Levels of TG,TC,HDL-C,and LDL-C were lower in group ZTH than in group CH (P ＜ 0.05).Conclusions Zinc selenium tea can lower blood levels of glucose,lipid,and cholesterol in rats fed with high-fat,high-sugar diets.
ABSTRACT
Objective: To study the health effects of selenium tea on cardiovascular system. Methods : Four groups of Wistar rats were fed standard diet and water, standard diet and selenium tea , high fat diet and water ,high fat diet and selenium tea respectively. Twelve weeks later, the plasma apoA , apoB, body weight, whole blood viscosity , plasma viscosity , and hematorcrit were determined while plasma fibrinogen and inhibition of erythrocyte aggregation were calculated. Results: At the end of the experiment ,the plasma apoA level of selenium tea groups was significantly higher than that of control group, while the ratio of apoB/apoA was significantly lower than that of control group. Selenium tea decreased the whole blood viscosity, plasma viscosity and inhibited erythrocyte aggregation and body weight. Conclusion: Selenium tea could significantly improve the lipoprotein metabolism and hermorrheology and decrease body weight of the rats fed high fat diet.
