[Effect of Zea pollinium on the structure and function of erythrocyte membrane in rats].
The aged-related changes of ATPase activity as well as the contents of MDA, sulfhydryl and sialic acid of erythrocyte membrane had been observed in many studies. In this paper, the effect of Zea pollinium on the structure and function of erythrocyte membrane in rats was observed. 12 male rats were divided randomly into pollen and control groups, the former was fed with diet containing 10% Zea pollinium; while no pollen for the latter.


RESULTS
After feeding for 10 weeks, the Na+, K(+)-ATPase and Ca2+, Mg(2+)-ATPase activities were 311.5 +/- 35.5 and 813.8 +/- 43.4 nmolPi/mg protein.h respectively in pollen group, significantly higher than that of the control group (209.9 +/- 23.9 and 624.9 +/- 23.3 nmolPi/mg protein.h). The contents of sulfhydryl and sialic acid were also increased, but the content of MDA was markedly decreased with the use of Zea pollinium. These results indicated that Zea pollinium could inhibit formation of lipid peroxidates, protect the structure and function of erythrocyte membrane from the injury of peroxidate.
