Abstract

Haw (Crataegus pinnatifida Bunge) has been used in traditional medicine for treating various ailments such as obesity and digestive trouble in Far East countries, including Korea. The present study was carried out to investigate the effects of feral haw on hepatic functional enzymes in dyslipidemic rats. Four groups of male rats (Sprague Dawley strain) were fed different diets for 5 weeks: NND (normal-nondyslipidemic diet) group, NNDH (normal-nondyslipidemic diet + haw extract) group, CDD (control-dyslipidemic diet) group and DDH (dyslipidemic diet + haw extract) group. ALP (alkaline phosphatase), LDH (lactate dehydrogenase), AST (aspartate aminotransferase) and ALT (alanine aminotransferase) activities were significantly higher in the CDD group than the NND group. However, haw extract supplement significantly reduced hepatic functional enzyme activities compared to the CDD group. Lipid deposition of the DDH group decreased compared to the CDD group. The size of adipose tissue decreased significantly in the DDH group compared to the CDD group. These results suggest that feral haw could be used as a food resource and functional food material.

산사(Crataegus pinnatifida Bunge) 중의 생리활성물질이 이상지질혈증에 있어서 간 조직 및 간 기능 대사효소의 활성 변화 등에 생리적 효능이 있을 것으로 판단되어 Sprague Dawley계 수컷 흰쥐를 이용하여 실험을 수행하였다. 대조군인 NND군, 대조군에 산사 추출물을 섭취시킨 NNDH 군, 이상지질혈증군인 CDD 군, 이상지질혈증군에 산사 추출물을 섭취시킨 DDH 군으로 나누어 5주간 실험 사육하였다. ALP(alkaline phosphatase), LDH(lactate dehydrogenase), AST(aspartate aminotransferase) 및 ALT(alanine aminotransferase) 활성은 모두 동일한 경향을 나타내었다. NND 군과 NNDH 군 간에는 유의적인 차이가 없었다. 이상지질혈증군인 CDD 군이 가장 높은 활성을 보였고, 이상지질혈증군에 산사 추출물을 섭취시킨 DDH 군에서 감소하는 것으로 나타났다. 간장의 조직학적 검사는 NND 군과 NNDH 군에서는 어떠한 이상 소견도 발견하지 못하였으나, CDD 군에서 지방 세포의 수와 크기증가, 지방 변성 및 염증 세포 등이 관찰되었고, DDH 군에서 지방 세포의 수와 크기가 줄어들었으며, 지방 변성 등이 감소된 것을 관찰할 수 있었다. 따라서 산사 추출물은 지방세포 분화 억제 및 지방 분해 작용과 간 기능 개선 효과 있는 것으로 추정되며, 간 보호 기능성 물질로서 활용 가능성이 우수할 것으로 사료된다.
