ABSTRACT
Objective:
To investigate the biological function of soybean selenoprotein by the study of anti-oxidation,immunological and anticarcinogenic efficacy.Method:
The soybean selenoprotein at different doses of Se were fed intra-gastrically in Kunming mice. A low Se feedstuff was used as basic diet.Result:
(1) when dose is below 202.5 ?g/kg bw Se, the number of white cell and red cell was increased remarkably, and the activity of GSH-Px and SOD in liver and serum was increased at dose dependent manner, but LPO in serum and liver was decreased noticeably. At level of 607.5?g/kg, all the indices were reversed; (2) A dose-dependent cancer protective effect was expressed in range of 22.5-202.5?g/kg Se of soybean selemoprotein in the diet. Feeding soybean selenoprotein can postpone the death of mice with carcinoma . Total tumour yield was consistently reduced by 78% with 202.5?g/kg supplementation; (3) Any abnormal response was never noticed during all trial by supplementing 202.5?g/kg selenoprotein.Conclusion:
The increased effect of anti-oxidation and immunological modulation might be the mechanism of tumour suppression by soybean selenoprotein, and Kunming mice tolerated the soybean selenoprotein very well without any side effects.
