Abstract

Plasma atrial natriuretic factor (ANF) was measured in 16 marmots at various times of the year. Nonhibernating males (n = 6) had an average plasma concentration of 56 +/- 8 pg/ml; nonhibernating females (n = 6) had an average plasma concentration of 61 +/- 4 pg/ml. During hibernation an additional group of females (n = 4) showed an average of 25 +/- 5 pg/ml. Plasma ANF of both groups of nonhibernating marmots was significantly higher (P less than 0.01) than that the hibernating group, but there was no difference between nonhibernating males and females.

摘要

在一年中的不同时间对16只土拨鼠的血浆心房利钠因子（ANF）进行了测量。非冬眠雄性土拨鼠（n = 6）的血浆平均浓度为56±8皮克/毫升；非冬眠雌性土拨鼠（n = 6）的血浆平均浓度为61±4皮克/毫升。在冬眠期间，另一组雌性土拨鼠（n = 4）的血浆平均浓度为25±5皮克/毫升。两组非冬眠土拨鼠的血浆ANF均显著高于冬眠组（P<0.01），但非冬眠的雄性和雌性土拨鼠之间没有差异。
