[Effect of Qinggong Zhixue Granule on low immunity mice].
OBJECTIVE
To probe into the pharmacological mechanism of the Chinese medicinal compound Qinggong Zhixue Granule (QGZXG), which has an effect of replenishing qi to activate blood and expelling stasis to stop bleeding, in treating irregular vaginal bleeding after medical abortion.


METHODS
Healthy female KM mice and mice with immunodeficiency caused by cytoxan (CTX) were chosen as experimental subjects. The effects of QGZXG on the phagocytization of the mice's monocytes (by using the method of carbon particles expurgation), the delayed type hypersensitivity caused by 2,4-dinitrochlorobenzene (DNCB) and the content of antibody of hemolysin in the mice's serum were observed.


RESULTS
(1) QGZXG improved the ability of the liver and spleen of immunodeficient mice to expurgate carbon particles. There was an significant statistical difference between the CTX treated group and the low dose group as well as the high dose group (P < 0.01) and a statistical difference between the CTX treated group and the medium dose group (P < 0.05). (2) QGZXG boosted the cellular immunity of immunodeficient mice. The ear swelling of mice in low, medium and high dose group was more obvious than that in the CTX treated group, and this difference was significant in statistics (P < 0.01). (3) QGZXG raised the content of the antibody of hemolysin in the serum of immunodeficient mice. A statistical difference occurred between the high dose group and the CTX treated group. The low and medium dose also had a tendency of such effect.


CONCLUSIONS
QGZXG can improve both the specific and non-specific immunity of the immunodeficient mice, and therefore accelerate the recovery of the whole body and endometrium after parturition and abortion. In consequence, it leads to shorter duration and less quantity of vaginal bleeding after medical abortion.
