Abstract
Prepubertal period in rats is characterized by some peculiarities of the cardiac regulatory mechanisms. In 6-week-old rats atropine produced bradycardia instead of tachycardia. Similar reaction was not observed in chemically sympathectomized age-matched rats.
摘要
大鼠青春期前阶段的特点是心脏调节机制存在一些特殊之处。在6周龄大鼠中，阿托品引起的是心动过缓而非心动过速。在化学性交感神经切除的同龄大鼠中未观察到类似反应。
