Purpose : The experiments was undertaken to evaluate the effects of herbal medicine, Ojeoksan, in pregnant rats
Methods : Female Sprague-Dawley rats were orally administered with the Ojeoksan at dose of 5mg/kg/day for 20 days. Pregnant rats were sacrificed at 20th day of gestation, and observed internal and reproductive organs. Approximately live fetuses in the 20th day of gestation were randomly selected and fixed in 95% ethanol.
Results : Maternal body weight of Ojeoksan treated group has a tendency to increase compared to that of control group. There were no significant difference in internal and reproductive organs. There were no significant changes between two groups in blood chemistry and hematological values. There were no significant changes in number of corpus luteum, implantation, live fetuses and sex ratio. But Ojeoksan administered group showed higher delivery rate, early resorption rate than the control group. Also Ojeoksan administered group showed higher implantation rate, late resorption rate than the control group.
Conclusion : From these results, it can be concluded that Ojeoksan showed no toxicity effects on maternal body weight and number of live fetuses. There were no significant changes in organ weight, hematological data, reproductive organs. We need more precise study to investigate the mechanism of early or late resoption by the herbal medicines such as Ojeoksan.
