Abstract

This study was performed to observe the effects of the feeding Prunus persica Batsch var davidiana Max. extract on the improvement of the free fatty acid, creatine phosphokinase and lecithin cholesterol acyltransferase(LCAT) activities in the serum of dietary hypercholesterolemic rats(S. D. strain, male) fed the experimental diets for. 5 weeks. Concentration of electrolyte(Na, K, Cl) in serum were fairly reduced in the group BCP(basal diet + cholesterol + Prunus persica, $5.0\;g\%$ extract) than in the group BCW(basal diet + cholesterol + water). However, no significance was found in the effect of an electrolyte concentration among the groups. Concentrations of free fatty acid, lipid peroxide and creatine phosphokinase activity in serum were significantly higher in the cholesterol administration groups(group BCW, BCP) than those in the control group(group BW, basal diet + water). However, concentrations of free fatty acid, lipid peroxide and creatine phosphokinase activity in serum were remarkably lower in the group BCP than those in the group BCW The LCAT activity in serum was increased in the Prunus persica $5.0g\%$ extract administration group(group BCP) than in the cholesterol of diet group(group BCW). From these results, the Prunus persica Batsch var davidiana Max. extracts were found to be effective on the improvement of the lipid compositions in serum of dietary hypercholesterolemic rats.

식이성 고콜레스테롤혈증 유발 Sprague Dawley계 숫 흰쥐를 사용하여 돌복숭아(Prunus persica Batsch var. davidiana Max.) 생리활성물질 추출액을 급여하므로서, 혈청 유리지방산, creatine phosphokinase 및 lecithin cholesterol acyltrasferase(LCAT) 활성 등 생체 내 지질 대사 이상 및 혈청 지질 개선 효과를 생리생화학적 측면에서 검토하기 위하여 본 실험을 수행하였다. 기본 식이에 물 급여군인 대조군(BW군)과 돼지기름, 콜레스테롤 등에 의한 고콜레스테롤 유발 식이에 물 급여군(BCW군), 고콜레스테롤혈증 유발 식이에 돌복숭아 $5.0 g\%$ 추출액을 급여한 군(BCP군)을 5주간 실험 사육하였다. 혈청 중 전해질 농도(Na, K, Cl)는 고콜레스테롤혈증 군에 돌복숭아 추출액을 급여하므로서 농도가 다소 감소되는 경향을 보였지만 전해질 농도의 저하효과는 유의성 있게 관찰되지 않았다. 혈청 중 유리지방산, 과산화지질 농도 및 creatine phosphokinase 활성 등은 돌복숭아 추출액을 급여한 군에서 농도와 활성이 감소되는 것으로 나타났다. 반면, 혈청 LCAT 활성은 고콜레스테롤 유발군에 돌복숭아 추출액 급여에 의해 증가되는 것 등으로 미루어 보아, 돌복숭아 중의 생리활성물질이 식이성 고콜레스테롤혈증 흰쥐에 대한 혈청 지질 개선 효과가 있는 것으로 사료된다.
