Abstract
본 연구는 선형가속기의 고에너지 엑스선을 조사한 생쥐 간에 대한 백삼과 동충하초의 방사선방호효과를 연구하였다. ICR계 수컷생쥐 군에 7일 동안에 경구적으로 백삼(150 mg/kg/day)과 동충하초(200 mg/kg/day)를 각각 방사선조사 전에 투여했고 다른 생쥐 군에 5 Gy(1.01 Gy/min)의 방사선량으로 전신조사를 했고 대조군에 생리적 식염수 (0.1 ml)를 투여 한 후 간 조직에서 환원형 글루타치온(GSH)과 산화형 글루타치온(GSSG)의 함량을 각각 검사하였다. 그 결과 방사선조사군(Rad)보다 동충하초투여군(EF+Rad)과 백삼투여군(WG+Rad)에서 환원형 글루타치온 (GSH)함량이 유의성 있게 증가했으나 산화형 글루타치온(GSSG)의 함량은 유의성 있게 감소하였다. 총 환원형 글루타치온(total GSH)과 산화형 글루타치온(GSSG)의 함량 비율은 방사선조사군(Rad)보다 동충하초투여군(EF+Rad)과 백삼투여군(WG+Rad)에서 유의성 있게 감소하였다. The radioprotective effects of white ginseng and Entomopathogenic Fugi Extract on liver damage induced by X-ray were investigated. To one group of ICR male mice were given white ginseng(150 mg/kg/day for 7days, orally) and Entomopathogenic Fugi (200 mg/kg/day for 7days, orally) before X-ray irradiation. To another group were irradiated by 5 Gy(1.01 Gy/min) dose of X-ray. Contrast group were given with saline(0.1 ml). The levels of reduced(GSH) and oxidized(GSSG) glutathione in liver tissue were measured. The ratio of GSSG/total GSH was significantly decreased in the white ginseng and Entomopathogenic Fugi (200 mg/kg/day)(150 mg/kg/day) groups than irradiation group.
