Purpose : Cuscuta chinensis Lam. is utilized extensively as important medicines for threatened abortion habitual abortion. However, objective data related to an embryo is not existed until now. Therefore, this study is focused to find out stability of Cuscuta chinensis Lam. about an embryo during pregnancy based on data related to stability of nerve cell and antioxydative effect by using neural cell line, PC 12 cell. Methods : Experimentation concerns cytotoxic effects and antioxydative effect through methods such as MTT ssay, western botting after abstracting an undiluted solution from domestic Cuscuta chinensis Lam. Results : 1. As a result of experimentation on MTT assay according to each magnification from Cuscuta chinensis Lam. extraction solution with different abstraction methods, cytotoxic effect is not observed to all extract except an undiluted solution which is abstracted from MeOH stiring. Also, an undiluted solution in stiring with MeOH could not confirm whether come from Cuscuta chinensis Lam. or not. 2. As a result of revelation of Bax and GSK-3${\beta}$ which is responsive to the first stage from general stress in order to observe antioxydative effects of Cuscuta chinensis Lam. revelation of Bax by Cuscuta chinensis Lam. appeared to decrease. Conclusion : Cytotoxic effects with Cuscuta chinensis Lam. about PC12 cell is not discovered and it assume that it would be anti apoptotic effect by ROS as Bax and GSK-3${\beta}$ inviable effect. In the future, this study could be used as basic data for additional research on Cuscuta chinensis Lam. and effect and stability of complicated prescriptions for keeping pregnancy.

본 연구에서는 미역이나 다시마에 많이 분포하면서 항산화작용이 탁월한 알긴산올리고당의 방사선 방어효과를 알아보기 위해 3 Gy 방사선이 전신 1회 조사된 마우스를 가지고 IL-6을 측정하였다. 측정 결과 방사선조사대조군과 비교하여 볼 때 소장과 간 조직 모두 방사선조사 전 7일간 알긴산올리고당의 처치를 시행한 그룹에서 IL-6 생성이 억제됨을 관찰하였다(p < 0.001). 이는 알긴산올리고당이 항산화작용을 통해 방사선이 피폭된 생체조직을 방어함으로써 IL-6의 생성을 억제한 것으로 사료된다. 결론적으로, 본 연구를 통해 알긴산올리고당의 일부 방사선 방어효과를 규명했고 아울러 화학적 독성이 없는 자연산생물이 방사선 방어제로 활용될 수 있을 가능성을 확인하였다.
