Objective To investigate the efficacy of acupoint injection of Astragalus on contents of SOD,HYP and MDA in skin of aging mice in-duced by D-galactose. Methods The mice were randomly divided into normal group,model group,Astragalus group,and saline group(n=15). Except for the normal control group,the mice of other groups were treated with continuous subcutaneous injection of D-galactose to establish mice ag-ing model. The Astragalus group mice was injected with 0.01mL Astragalus in Sanzuli acupoint per day,The saline group mice received an injection of same amount of saline. SOD,HYP and MDA changes in the skin tissue and serum were evaluated after 21 days. Results All the index in the skin tissue and serum showed significant difference(P<0.01)between model group mice and normal control group. Compared with model group,SOD activity and MDA content in the skin tissue and serum of the Astragalus group mice were significantly raised,HYP content was significantly reduced (P<0.01). There also were significant differences of these index between the saline group mice and the model group(P<0.05),but the effect was not as good as the Astragalus group mice. Conclusion Acupoint Injection of Astragalus can prevent and protect against skin aging induced by D-galactose.

Cordyceps sinensis is an expensive and tonic-valuable famous herb in China. Due to a narrow growing distribution, a low parasitic rate and a harsh living environmental condition, its wild recourse is not abundant. In re-cent years, with the improvement of living standards, people’s awareness of health care has increased strongly. That is because of people’s over-excavation need;and the natural resources are becoming increasing scarcity. In order to meet the demand for Cordyceps, domestic researchers conducted vigorous studies. Since 1987, four or five cul-tured Cordyceps species have been developed, namely fermented Cordyceps sinensis. Through subsequent unceasing research, they were put into a lot of production, bringing a certain benefits for income and society. Currently, there are four commercial brands on the market. They are Bailing, Jinshuibao, Xinganbao and Ningxinbao. This paper summarized the studies of its chemical compositions and clinical applications on fermented Cordyceps militaris in the recent five years. It will let scholars understand its value of the cultured Cordyceps militaris more comprehen-sively and supply more information for scholars in its further research.
