摘要

在妊娠第12、19和21天，测定了初孕大鼠和妊娠大鼠肝脏、后腿骨骼肌、脑、肾周白色脂肪组织、肩胛间棕色脂肪组织和血液以及胎盘、胎肝和胎血的(Na+-K+)- atp酶活性，以评价其在妊娠代谢物运输过程和产热过程中的相对作用。与对照组相比，妊娠大鼠肝脏、血液和白色脂肪组织中的(Na+-K+)- atp酶活性没有变化。妊娠期肌肉、脑和肩胛间棕色脂肪组织(Na+-K+)- atp酶活性降低，妊娠第21天胎盘(Na+-K+)- atp酶活性较妊娠第12天升高。胎儿肝脏和胎儿血液均未见明显变化。

(Na+-K+)-ATPase activities in rat tissues during pregnancy.

(Na+-K+)-ATPase activities of liver, hind leg skeletal muscle, brain, perirenal white adipose tissue, interscapular brown adipose tissue and blood as well as placenta, fetal liver and fetal blood were determined in virgin rats and pregnant rats on days 12, 19 and 21 of gestation in order to evaluate its relative contribution either to metabolite transport processes or/and to thermogenesis during pregnancy. No changes were found in (Na+-K+)-ATPase activity in liver, blood and white adipose tissue in pregnant rats versus controls. (Na+-K+)-ATPase activity from muscle, brain and interscapular brown adipose tissue decreased during pregnancy and placenta showed an increase of (Na+-K+)-ATPase on day 21 of gestation in respect to day 12. No significant changes were observed either in fetal liver or fetal blood.
