Erythrocyte glutathione peroxidase activity and serum lipid pattern: A comparison between Indian immigrants and Danes

A comparative data on erythrocyte glutathione peroxidase (GSH-Px) activity, serum cholesterol and serum fatty acid pattern between Indian immigrants and Danes have been presented. The erythrocyte GSH-Px activity in the Indian immigrants has been found to be significantly increased as compared to that in the Danish group when t-buthylhydroperoxide was used as a substrate. Also a significant correlation (R less than or equal to 0.09) was found in the GSH-Px activities in the Indian group with the three peroxides, viz., hydrogen peroxide, cumene hydroperoxide and t-butylhydroperoxide, used. This correlation was, however, missing in the Danish group. Serum cholesterol was found to be significantly lower in the Indian group as compared to the Danes. Also total serum fatty acid patterns between the two groups differed considerably.
