Objective To investigate the effect of dietary calcium on plasma lipoprotein profile in castrated and ovariectomized hamsters.Methods Male,castrated,female and ovariectomized hamsters(n=36 each group) were randomly divided into three sub-groups(n=12) and fed one of the three diets containing 0,2,and 8 g calcium per kg diet for a period of six weeks.Changes in plasma lipoprotein profile were monitored at the end of week 0,3 and 6.Results Plasma total cholesterol(TC),non-high density lipoprotein cholesterol(non-HDL-C),triacylglycerols(TG) and TC/HDL-C were decreased only in intact female and ovariectomized hamsters.In contrast,three levels of dietary calcium had no effect on lipoprotein profiles in both intact male and castrated hamsters.Conclusion Beneficial modification of lipoprotein profile by dietary calcium was gender-dependent at least in hamsters.

Methods Male, castrated, female and ovariectomized hamsters (n = 36 each group) were randomly divided into three sub-groups (n = 12) and fed one of the three diets containing 0,2, and 8 g calcium per kg diet for a period of six weeks. Hearts in plasma lipoprotein profiles were monitored at the end of week 0,3 and 6. Results Plasma total cholesterol (TC), non -high density lipoprotein cholesterol (non-HDL-C), triacylglycerols (TG) and TC / HDL-C were decreased only in intact female and ovariectomized hamsters.In contrast, three levels of dietary calcium had no effect on lipoprotein profiles in both intact male and castrated hamsters.
