RESUMEN
Traditional Chinese medicine injection(TCMI) is a new preparation developing recent years, which is spreading because of the significant effect. Doctors acquire information of medicine from the prospectuses mainly. But due to many reasons, there are a lot of shortcomings such as lack of items, unknown of composition, the narrow scope, etc. Unreasonable drug use in field and dose happened frequently. Adverse reactions are often reported. They restricted the use of TCMI severely. We must pay attention to the market evaluation of TCMI, and improve the prospectuses gradually on the basis of clinical evidence. One hand, the use of drugs can be reference to it. On the other hand, it can avoid unreasonable use of drugs. We have done it in order to contribute to the clinical application of TCMI.

The effect of angiotensin II (Ang II) on the follicular development was studied by using an animal model of follicular atresia induced by pregnant mare s serum gonadotropin (PMSG). The results showed that: (1) a large number of atretic follicles were found in the ovary of 24-day-old mouse after 6-day treatment of PMSG. Deoxyribonucleic acid (DNA) extracted from granulosa cells clearly showed a ladder band under agarose gel electrophoresis analysis. (2) the contents of Ang II in the ovary extremely increased with the development of follicular atresia. (3) Ang II significantly antagonized the stimulating effect of the follicle-stimulating hormone (FSH) on estradiol (E(2)) generation of granulosa cells. It is suggested that Ang II may be involved in the regulation of follicular atresia in mouse.
