EFFECTS OF SUPRANUTRITIONAL LEVELS OF YEAST-SELENIUM ON ANTIOXIDATION STATUS AND IMMUNE FUNCTION IN MICE WITH TUMOUR / 营养学报

ABSTRACT

Objective:To study the effects of supranutrional levels of yeast-selenium on antioxida-tion status and immune function in mice with tumour.Method:Sixty KM mice were divided into three groups control group,yeast-selenium Ⅰ group and Ⅱgroup.The mice were supplemented with 0.5ml normal saline,3.2 ?g and 6.4 ?g yeast-selenium respectively by gavage on time a day based on the low selenium diet.The mice were inoculated with Ehrich ascites carcinoma(EAC) after 13 d.The tumour weight and immune function and antioxidative indices in blood were measured after 23 d.Results: The two yeast-selenium levels increased the activities of GSHPx(P
