This study was designed to investigate the influence of Eosungcho (Houttuynia cordata Thunb) mixture on the plasma lipids of pigs. Experimental groups were divided into 3 groups: control group(0%), 5% and 10% Eosungcho feeding groups. Plasma concentration of total cholesterol, atherosclerotic index, free cholesterol and cholesteryl ester were significantly lower in the Eosungcho powder 5% and 10% feeding groups than control group. Plasma contents of HDL-cholesterol, cholesteryl ester ratio, triglyceride and phospholipid were significantly different between 10% Eosungcho feeding group and control group. Plasma concentration of LDL-cholesterol was significantly love in 10% Eosungcho feeding group($76.5{\pm}5.4mg/dL$) than in control group($86.5{\pm}5.6mg/dL$). Plasma concentration of VLDL and chylomicron were showed similar tendency to LDL-cholesterol. Also, blood sugar, GOT and GPT concentration were significantly lower in 10% Eosungcho feeding group than in control group. In control group, the ratio of saturated fatty acid to unsaturated fatty acid was 58.1 : 51.9, but in 5% and 10% Eosungcho feeding groups, those were 42.1 : 57.9 and 41.0 : 59.0, respectively. The component of main fatty acid was different between control group and Eosungcho feeding groups. In Eosungcho feeding groups, main unsaturated fatty acids were oleic acid(18:1) and linoleic acid(18:2). From the results, addition of Eosungcho powder might be effective in improving the plasma lipid components in pigs.

The study was designed to investigate the influence of feeding Eosungcho(houttutnia cordata Thunb) on the meat quality of porks. Experimental groups were divided into control group(C), 5%(T1) and 10%(T2) Eosungcho powder feeding group, and than administered for 12 weeks. And then pork's loins were storaged at $4^{\circ}C$, for 23 days after vaccum packed. TBARS was increased(P<0.05) during storage days in all samples, while it's contents were lower Eosungcho feding groups than control group. Total cholesterol contents of pork's loin, were $48.9{\pm}0.2\;mg/100\;g$ in control group, $39.1{\pm}0.2\;mg/100\;g$ in T1 group and $37.8{\pm}0.3\;mg/100\;g$ in T2 group. 4 kinds of cholesterol oxides($7{\beta}-hydroxycholesterol$, 19-hydroxycholesterol, ${\alpha}-$ and ${\beta}-epoxide$) detected in pork's loin. Cholesterol oxides concentration of pork's loin was increased during storage and lowest in T2 group.

This study was carried out to investigate the influence of feeding eosungcho (Houttuynia cordata Thunb) powder on the meat quality of porks at chilled storage. Experimental groups were divided into control group (0%, C), 5% (T1) and 10% (T2) eosungcho powder feeding group, and then administered for 12 weeks. The results of sensory evaluation for softening value and scorched smell showed the highest preference in T1 group. Overall acceptability was also the highest in T1 group than the others. Physicochemical components were analyzed for pork loins that were stored at $4^{\circ}C$ for 23 days after vacuum packing. The moisture contents of pork loins were higher in T1 group than the others. Crude lipid contents were lower in T1 and T2 groups than the control group. The pH values were not significantly different in experimental groups during storage days. The Hunt L and a values increased significantly according to storage days. The Hunt b value was increased for the initial storage days but it did not change after 9 storage days. The Warmer-Bratzler share force of all experimental groups were greatly decreased between 2 and 9 storage days and then little exchanged afterwards.

Objectives : This study was performed to investigate the anti-fibrogenic effect and the effect on cell growth and apoptosis in YJCGT, YJCGT YSO and YJCGT YSCO on thioacetamide-induced rat liver tissue and the immortalized human hepatic cell line LX2. Materials and Methods : LX2 cells were treated with various concentrations (0, 50, 150, 300 ug/ml) of YJCGT, Y+YSO, and Y+YSCO extract for 24, 48 and 72 hours. After the treatment, cell viability was measured by using MTT assay. Caspase inhibitor assay, and cell viability were determined by a colorimetric assay with PMS/MTS solution. Rat liver fibrosis was induced by intraperitoneal thioacetamide injection 150 mg/kg 3 times a week for 5 weeks. After the treatment, body weight, liver & spleen weights, liver function test, the complete blood cell count and the change of portal pressure were studied. After YJCGT, Y+YSO, and Y+YSCO treatment, percentages of collagen in thioacetamide-induced rat liver tissue were measured. Results : The viability of the LX2 cell decreased in a dose- and time-dependent manner. Exposure of LX2 cells to YJCGT, YJCGT+YSO and YJCGT+YSCO induced caspase-3 activation, but co-treatment of YJCGT, YJCGT+YSO and YJCGT+YSCO with the pan-caspase inhibitor Z-VAD-FMK, and the caspase-3 inhibitor Z-DEVE-FMK, blocked apoptosis. There was no difference in rat body weight between the thioacetamide only group and the YJCGT, YJCGT+YSO and YJCGT+YSCO groups. In the YJCGT, YJCGT YSO and YJCGT YSCO groups, the serum level of GPT significantly went down compared with the thioacetamide only group. In the YJCGT, Y+YSO, Y+YSCO groups, white blood cell elevated by thioacetamide injection decreased but RBC, Hgb, and Hct increased. In the Y+YSO group, the portal pressure elevated by thioacetamide injection significantly decreased. In the histological finding, thioacetamide injections caused severe fibrosis, but YJCGT, Y+YSO, and Y+YSCO treatment significantly reduced the amounts of hepatic collagens. Conclusions : YJCGT, Y+YSO, and Y+YSCO inhibit the growth of LX2 cells by inducing apoptosis through caspase activity. YJCGT, Y+YSO, and Y+YSCO have beneficial effects on the treatment of cirrhotic patients as well as patients with chronic hepatitis.
