Gender difference in activation of platelets in septic rats / 第二军医大学学报

ABSTRACT

Objective:To investigate the influence of gender difference on the activation of platelets in septic rats.Methods: Totally 20 female and 20 male SD rats were randomly divided into four groups male sham-operated group,female sham-operated group,female septic group,and male septic group,with each group containing 10 rats.Sepsis model in the last two groups was produced by cecal ligation and puncture(CLP);rats in the sham-operated group received no CLP.The rats were sacrificed 24 hours after surgery;the blood samples were collected for blood routine test;and the serum ?-TG levels were detected by ELISA assay.Serum estrogen(E2) levels were detected by radioimmunoassay.Results: The blood platelet counts were decreased in both septic rats of both genders;the count in female rats was significantly higher than in the male rats(P
