고지방식이 흰쥐에서 산초나무 Butanol 및 Methylene Chloride분획의 항혈전 및 항염증 작용

This study was performed to investigate anti-thrombogenic, anti-inflammatory effects of n-BuOH (B) and $CH_2Cl_2$ (MC) fractions extracted from Sancho (Zanthoxylum. schinifolium) leaves in rats fed high fat diets. The experimental animal groups were consisted of eight including one 5% fat (N) and one 20% fat (H) without the test materials in diets and six H groups of feeding three levels (50, 100 and 150 mg/day) of the B and the MC fractions from Z. schinifolium, respectively. Plasma activated partial thromboplastin times and thrombin times of H group were decreased compared to the N group, but they were increased by feeding the MC fraction of 50 mg and over. Polymorphonuclear leukocyte 5#-lipo-xygenase activities and leukotriene $B_4$ contents of the H group were significantly increased compared to the N group, but they were decreased in the 100 mg and 150 mg of B fraction or the 150 mg of MC fraction fed groups. Liver cytochrome $P_{450}$, $O_2^-$, $H_2O_2$ and GSSG contents were increased by the high fat diet but decreased by feeding the B fraction or the MC fraction, while GSH content and glutathione S-transferase activity lowered by high fat diet were increased by feeding the two solvent fractions. The effects of the solvent fractions were evident at the level of 100 mg/day and over. The present results confirmed that two solvent fractions from the leaves of Z, schinifolium have enhancing effects on anti-thrombosis and anti-inflammation partly by antioxidant action and partly by direct modulation of the respective processeds. In conclusion, the n-BuOH and $CH_2Cl_2$ fractions from leaves of Z, schinifolium can be utilized as the proper ingredients of functional foods for preventing chronic degenerative disease. 본 연구에서는 in vitro에서 검색된 산초나무 잎의 용매분획의 항혈전 및 항염증작용을 in vivo에서 확인하고자 고지방식이를 섭취한 흰쥐에게 n-butanol 분획과 methylene chloride분획을 1일 50, 100, 150 mg을 4주간 경구투여 하였다. 혈장 APTT 및 TT는 정상식이군에 비해 고지방식이군에서 유의적으로 감소되었으며, 고지방식이군에 methylene chloride분획 50 mg 이상 공급군은 유의적으로 증가되어 100 mg 이상 공급군은 정상식이군 수준이었다. 다형핵 백혈구 5#-lipoxygenase 활성과 leukotriene $B_4$ 함량이 정상식이군에 비해 고지방식이군에서 증가되었으며, 5#-lipoxygenase 활성은 두 용매 분획을 100 mg 이상 공급한 군들이 모두 감소하였다. 백혈구의 leukotriene $B_4$ 함량은 n-butanol 분획에 의하여 역시 100 mg 이상 공급으로 감소하였으나 methylene chloride 분획에 의하여는 150 mg 공급군에서만 감소하였다. 간 조직 마이크로솜의 cytochrome $P_{450}$ 함량은 정상식이군에 비해 고지방식이군에서 유의적으로 증가되었으며, 두 용매분획의 투여로 감소하는 경향이었으나 butanol 분획 150mg 투여군에서만 유의적으로 감소하였다. 간 조직 $O_2^-$M의 함량과 $H_2O_2$ 함량도 정상식이군에 비해 고지방식이군에서 증가되었으며, butanol 분획 100 mg 이상투여로 $O_2^-
