[A comparative study on the effect of absorbable components of several drugs on the growth and population doublings of rat diploid fibroblast].

Embryonic skin fibroblast of Sprague-Dawley rats cultivated in vitro was used in this experiment. The cultural medium was added with absorbable components of several drugs. The result reveals that Yan Shou recipe, vitamin E and Huan Jing Jian have conspicuous promotive effect on the growth of diploid fibroblast and also help to increase population doublings. The experiment suggests that all these drugs possess anti-aging effect on the skin diploid fibroblast of rats.
