Sprague-Dawley 흰쥐에 고지방식이로 6주간 식이하면서 천궁 열추출액을 경구투여하여 혈장, 간장 및 부고환조직에서 지방성분, 지단백질의 분포, 변중의 담즙산과 중성스테롤들의 배출량을 측정하여 다음과 같은 결과를 얻었다. 고지방식이와 천궁(CR군)열수추출액을 각각 투여한 흰쥐의 혈청중 총콜레스테롤, 중성지질 및 유리지방산의 농도는 고지방식이로만 사육한 군(CON군)에 비해 낮았다. 한편 인지질과 HDL-cholesterol의 농도는 다소 높았다. 또한 간장과 부고환의 지방성분들을 조사한 경우에도 위와 같은 결과를 얻었다. 고지방식이가 급여되는 동안 정상군보다 대조군에서 low density lipoprotein(LDL)과 very low density lipoprotein(VLDL)이 다같이 증가하고 high density lipoprotein(HDL)의 농도는 감소하였다. 천궁투여군에서는 대조군에 비하여 LDL, VLDL이 감소하였고 HDL은 증가하였다. 그리고 천궁투여군은 대조군에 비하여 분변을 통한 담즙산과 중성스테롤의 배설량이 증가하였다. 이상의 결과를 종합해 보면 천궁투여군이 지방축적 및 고지혈증의 완만한 개선경향을 나타내었다.
This study was carried out to evaluate the effect of Cnidi rhizoma(CR) water extract on fat accumulation in fatted rats induced by the oral high fat administration for six weeks. Total cholesterol, neutral lipid and epididymal fat pad of CR groups were lower than the control group. On the other hand, high density lipoprotein(HDL)-cholesterol was somewhat higher in CR than in the control group. In addition, the same result as the above case was obtained when examining adipose for liver and epididymal fat components. During the feeding experiment, level of low density lipoprotein(LDL) and very low density lipoprotein(VLDL) increased while HDL was decreased. The degree of LDL and VLDL was decreased however, and HDL was increased in CR groups as compared with the control group. Insulin and cortisol were higher than the control group, due to the fat accumulation. Experiment group showed the increased excretion as compared with the control group, in the excretion of bile acid and neutral sterol. The liver of the control group observed by the light microscope appeared to the fatty liver, but CR groups showed some improvement of the fatty liver. Based on the above results, it was shown that it is possible to improve fat accumulation induced by high fat dietary through using the oral administration of Cnidi rhizoma boiling extract solutions.
