Changes in blood parameters and the expression of coagulation-related genes in lactating Sprague-Dawley rats.

ABSTRACT: This study measured blood parameters, particularly those related to coagulation, and alterations in the expression levels of blood-coagulation-related genes in lactating Sprague-Dawley rats. The day of delivery was designated as lactation day 0 (LD 0). On the day after delivery (LD 1), prothrombin time and overall activity of vitamin-K-dependent coagulation factors were decreased, whereas fibrinogen contents, platelet counts and antithrombin III concentrations were increased as compared with those in nonpregnant rats. In addition, hepatic expression of blood-coagulation-related genes in the liver was increased at LD 0 as compared with that in nonpregnant rats. These changes may be physiologic responses to prevent prolonged bleeding at delivery. Except for fibrinogen content, which remained
