    Abstract:
    OBJECTIVE: To study the pathophysiological changes and effective treatment of intrauterine growth retardation (IUGR). METHODS: Eighty-five cases with normal pregnancy and 58 IUGR women maternal red blood cell superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), serum lipid peroxide (LPO) and thromboxane B2 (TXB2), 6-keto-PGF1 alpha(6KP) were examined. IUGR group was divided into Ligustrazine group (LIG, 47 cases) and amino acid group (AAG, 11 cases) and treated accordingly. RESULTS: In IUGR group, LPO increased and SOD, GSH-Px activity, 6KP value decreased abnormally, TXB2/6KP ratio significantly increased, which was negative correlated with SOD, GSH-Px activity and positive correlated with LPO level markedly. After treatment, all the changes were improved and almost reached normal range. The fetal outcome showed that the total effective rate was 95.7% in LIG, markedly higher than that in AAG (81.8%, P < 0.05), there was significant difference between LIG and AAG. CONCLUSIONS: The balance of body oxidate/antioxidate system was disturbed and the uteroplacental-fetal circulation was obstracted in IUGR. Ligustrazine could inhibit oxygen free radical, rise SOD, GSH-Px activity, regulate TXA2/PGI2 balance, promote fetal growth.
