The goal of the present study was to examine baroreflex control of heart rate during pregnancy in chronically instrumented unrestrained rats. The same rats (n = 6) were studied before conception, again on gestational days 5, 12, and 19, and last on postpartum day 6; thus each rat served as its own control. Time control experiments were also conducted in a separate group of virgin rats (n = 7). Resting mean arterial pressure decreased by 10 mmHg on gestational day 19 (P less than 0.01 vs… CONTINUE READING
