Abstract

Dandelion(Taraxacum officinale), an oriental herbal medicine, has been shown to favorably affect choleretic, antioxidative and protection of gastric mucosa. The protective effects of common dandelion leaf and root extract were investigated by irradiation in Sprague-Dawley rats. Male SD rats, 6weeks, were orally injected with dandelion extract(100mg/kg) for 10days. Immediately after final injection, rats were whole body irradiated with 10Gy used irradiation facility(Elekta Linac, Sweden). At 24h-15days after irradiation, complete blood counted test and apoptosis in jejunal crypt cell. Stimulated recovery by the extract was observed in platelet but was not showed in the erythrocyte and leucocyte. The jejunal crypt cells were protected significantly(p<0.05) and the radiation-induced apoptosis was reduced(p<0.05). The survival rate were carried for 15days, the survival ratio was 15% and 85% for the control and experimental group. Observations intestinal inhibition of cell death, intestinal mucosa and tissue decreased systemic inflammation and vacuole. Base on these data, we propose that dandelion may be a useful radioprotector, especially since it is a relatively nontoxic natural product.

민들레는 한방에서 산화방지, 위장 점막 보호 및 담즙 등에 탁월한 효과가 있다고 알려져 있다. 민들레 잎과 뿌리에서 추출한 물질을 SD Rat에 투여한 후 10Gy 방사선 조사 후에 생존율, 혈액변화, 소장조직변화 및 간 조직 변화를 관찰하였다. 관찰결과 민들레 추출물을 투여한 실험군에서 생존율이 4배 이상 높았으며 백혈구, 혈소판 등의 혈액변화에서도 뚜렷한 차이가 보였다. 또한 소장 조직 관찰결과 소장점막세포 소멸 억제 및 소장 점막근판 조직의 염증과 공포가 감소되었다. 따라서 민들레 추출물이 방사선 조사에 따른 혈액구성세포와 소장 조직 손상에 대한 방사선 방호효과를 확인하였다.
