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.

The purpose of this study was to examine the in vitro effects of body and visceral portion of Haliotis discus hannai on angiotensin converting enzyme (ACE) activity and antioxidant and anticoagulant capacity. Extracts from both abalone body and visceral portion using 80% ethanol showed a high ACE-inhibitory effect. While ACE-inhibitory effect of extracts of the body part was dose-dependent, visceral extracts did not show any difference by the level of concentration. ACE-inhibitory effect of the visceral portion was much higher than that of the body. Antioxidant capacity was increased with increasing concentration of 80% ethanol body extracts although the capacity was low. The 80% ethanol visceral extracts showed a similar level of antioxidant capacity to the body extract in low concentration. Water extracts showed a dose-dependent increase in the activity. There was no significant difference in the antioxidant activity between the body and the visceral part. Anticoagulant capacity of 80% ethanol extracts, which was measured using prothrombin time(PT), was higher in the body part than the visceral part. Water extracts of Haliotis discus showed no any significant effect on anticoagulant capacity. The in vitro effects were also examined after Haliotis discus was refrigerated for 48 hours. Higher ACE-inhibitory effect was observed for the visceral portion than the body, in particular, before the sample was refrigerated. Antioxidant effect of Haliotis discus increased with increasing level of the sample before it was refrigerated. However, there was a significant difference between the body and the visceral part, which showed significantly higher capacity. There was no significant difference between the body and visceral part in PT regardless of refrigeration. While activated partial thromboplastin time (APTT) showed no significant difference between body and visceral part, there was a significant difference in the capacity between before and after the refrigeration, which showed much lower coagulant capacity.
