Another study from Shanghai observed the clinical effectiveness of Chinese herbal medicine on endometriosis and the uterine arterial blood flow. The study group consisted of 53 women with endometriosis who manifested with dysmenorrhea, menoxenia, ovarian chocolate cysts and enlarged uterus. The control group consisted of ten women with normal regular menstrual cycle. This article deals with the method of using the hemodynamic index of uterus arterial blood flow. After treatment the blood flow amount of uterus arteries of 53 cases (study group) obviously decreased and their uterus arterial blood flow speed reduced markedly as compared with pre-treatment status, (P < 0.001 and P < 0.01 respectively), while pre-treatment group was significantly higher than that of control group (P < 0.001). After medical treatment for 3.5 months, symptoms such as dysmenorrhea and menstrual disorder basically disappeared. 22 ovarian chocolate cysts became smaller and 16 disappeared. The pregnancy rate was 45%. The data of this study suggest that the mechanism of treatment of promoting blood circulation to remove stasis might be closely related to the regulation of physico-chemical characteristics of blood and the adjustment of hemodynamics.
