本文通过离体兔肠平滑肌实验证明:卷柏对肠平滑肌的蠕动及张力都有明显抑制作用;且可拮抗BaCl_2及Ach增强肌张力的作用。而木贼使肠蠕动增强。对肌张力几无影响。两药对肠平滑肌的不同影响可能是卷柏复方产生双向作用的基础。
In this article, the experimental results of isolated rabbit intestinal smooth muscle demonstrate that Selaginella has a significant inhibitory effect on the peristalsis and tension of intestinal smooth muscle, and it can antagonize the effect of BaCl 2 and Ach on muscle tension. The wood thief enhances peristalsis. Little effect on muscle tone. The different effects of the two drugs on the intestinal smooth muscle may be the basis for the two-way effect of the Selaginella compound.
