80% extract of Gamigwaruhaebaekbaekju-Tang (GGHBT), Gagamgwaruhaebaekbaekju-Tang (GGGHBT) and Gamigwaruhaebaekwhanggum-Tang (GGHWT) remarkably showed inhibitory effects on HMG-CoA reductase, lipid peroxidation of rat liver and LDL oxidation, and DPPH free radical scavenging effect in a dose-dependent manner. Especially, GGHWT which is formulated with Trichosanthis Fructus, Pinelliae Tuber, Aurantii Immatures Fructus, Magnoliae Cortex, Allii Macrostemi Bulbus, Cinnamomi Ramulus and Scutellariae Radix on the basis of Gwaruhaebaekbaekiu-Tang listed on the traditional medicinal references showed more effective hypocholesterolemic activities in vitro bioassay than the other prescriptions.

In the previous reports, we selected 80% MeOH extract of 7 herbs including Scutellariae Radix(SR), Paeoniae Radix Rubra(PRR), Moutan Cortex(MC), Angelicae Gigantis Radix(AGR), Crataegi Fructus(CF), Bambusae Caulis in Taeniam(BCT) and Cinnamomi Ramulus(CR), which exhibited the inhibitory effect on HMG-CoA reductase and DPPH free radical scavenging effect in vitro, and antihyperlipidemic effects on antihyperlipidemic rats induced by Triton WR 1339 in vivo. Among them, SR, MC, AGR and BCT showed significant suppression of elevated serum LDL-cholesterol level, and AGR and CF showed significant liver weight increase on high cholesterol diet induced hyperlipidemic mice. And, SR, PRR, AGR, BCT and CR significantly suppressed the elevated serum total cholesterol and triglyceride levels on corn oil induced hyperlipidemic rats. Then, in order to research new antihyperlipidemic agents from the oriental medicinal herbs, we chose SR, AGR, CR and BCT which have the antihyperlipidemic effect in vitro and in vivo, and those herbs were systematically fractionated with organic solvent. EtOAc fraction of SR, hexane fraction of BCT, AGR and chloroform fraction of CR exhibited remarkably inhibitory effect on HMG-CoA reductase activity.

Renal tissues of ICR mouse were intraperitoneally injeced with Monostroma nitidum extract(ME) after Triton WR-1339(TX) injection were observed to investigate the lipid accumulation suppressive effect of ME. The renal tissues were obtained at hour 24, 48, and 72 after TX injection that were fixed in fromol-calcium solution and were cryocut. The tissue stained by H&E for general morphology, sudan black B for lipid and perchloric acid-naphthoquinone method for cholesterol. The parietal layer of Bowman's capsule is swatted as cuboidal type at hour 48 after TX injection and the lipid blot and cholesterol particle were noticeably increased in glomerulus than control group and these appeared in convoluted tubule, collecting tubule, and Helen's loop. But the parietal layer of Bowman's capsule was shaped as squamous type that was looked like as normal morphology in ME treated group after TX injection and the lipid blot and cholesterol particle were considerably decreased in glomerulus than TX group. As results indicated that the accumulation of lipid including cholesterol caused by TX injection were mitigated in renal tissues by the antihyperlipidermic effect of ME.

An extrapolation of bioflavone through biotransformation used Phellinus banmill KCTC16882 applied to 6 different rats group were carried out. Male Sprague-Dawley rats were fed with bioflavone free (normal: NO) diet, high-fat diet (control: CO) and diets containing 0.35%, 0.7% and 3.0% isoflavone for 8 week. Hyperlipidemia was induced by adding lard 200 g and cholesterol 10 g to CO and 0.35, 0.7 and 3.0% bioflavone diet. Bioflavone diet arrested increases in body weight without affecting feed intake in the rats. BFP-3.0 treated group showed signigicant reduction in the serum level of TG, TC and LDL-cholesterol (p<0.05) compared to the CO, while HDL-cholesterol was increased (p<0.05). The atherogenic index, ALT and AST were decreased in the BFP treated groups (p<0.05). These results suggest that consumption of BFP may lead to extrapolation of an ameliortaion of metabolic syndromes as well as a reduction of cardiovascular disease and hyperlipidemia through increasing the of HDL-cholesterol, and decreasing the level of TG in serum.

The physiological functionalities such as antimicrobial activity, antioxidative activity, angiotensin-I converting enzyme (ACE) inhibitory activity and bile acid binding capacity were measured for the solvent-fractionated methanol extracts of Alaska pollack sik-hae at various time intervals during fermentation. Two temperature schemes of fermentation were studied: constant temperature of 2$0^{\circ}C$ (A) and stepwise change from 2$0^{\circ}C$ (10 days) to 5$^{\circ}C$ (B). The methanol extracts of Alaska pollack sik-hae showed antimicrobial activities against 9 kinds of micro-organisms including pathogenic and food poisoning strains. Among these, gram positive bacteria, in particular Staphylococcus aureus, showed more sensitivity to the extracts than gram negative bacteria and fungi. Antioxidative activity (EDA$_{50}$) increased until 15 days (A, 0.92 mg/$m\ell$) or 16 days of fermentation (B, 0.94 mg/$m\ell$), and then gradually decreased. ACE inhibitory activity was observed in all fermentation time except 0 day, and bile acid binding capacity at 15 days (A) and 16 days (B) only.

This study investigated the antioxidant capacities and inhibitory activity of peeled lotus root (Nelumbo nucifera) as a food material on angiotension-converting enzyme (ACE). The antioxidant effects on total polyphenol and total flavonoid contents were not signicant. However, DPPH radical scavenging activity decreased from 85.07% to 80.70% by peeled treatment. SOD-like activity decreased from 20.84% to 17.97%, and ACE inhibitory activity decreased from 53.4% to 50.1% by peeled treatement. Thus, consumption of non-peeled lotus root should increase.

In this study, we investigated the antioxidant activities, alcohol metabolizing activities, nitrite scavenging ability, angiotensin converting enzyme (ACE), and elastase inhibitory effects of hot water extract from Makgeoly (HWM). Antioxidant activities were measured by using 2,2.diphenyl.1.picryl.hydrazyl (DPPH) free radical scavenging activity and SOD (superoxide dismutase).like activity. The DPPH radical scavenging activity and SOD.like activity of HWM were remarkably increased in a dose.dependent manner and were 48.0% and 98.7% at 10 mg/ml, respectively. To determine the influence of HWM on alcohol metabolizing activity, the generating activities of reduced.nicotinamide adenine dinucleotide (NADH) by alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) were measured. The facilitating rates of ADH and ALDH activity by HWM were remarkably increased in a dose.dependent manner and were 70.2% and 64.1% at 10 mg/ml, respectively. The inhibitory activity against angiotensin converting enzyme (ACE) of HWM was increased in a dose.dependent manner and was 74.2% at 10 mg/ml. The nitrite scavenging ability of HWM showed the most remarkable effect at pH 1.2 and 2 mg/ml. These results indicated that HWM may have valuable biological properties owing to their antioxidant activities, ADH and ALDH activity, nitrite scavenging ability, and ACE inhibitory activity.

The goal of this study was to screen a useful yeast for Korean traditional pear Yakju (KTPY) brewing and develop its brewing process. Cooked non-glutinous rice and nuruk were mixed, and added into pear juice with various Saccharomyces cerevisiae and then fermented at $25^{\circ}C$ for 7 days. Among several alcohol fermentation yeasts, ethanol contents was the highest in pear Yakju made by S. cerevisiae K-7 and also showed high ethanol content in pear Yakju which was made by commercial S. cerevisiae C-2. Therefore, we selected S. cerevisiae K-7 and S. cerevisiae C-2 as suitable yeasts for brewing of KTPY. Maximal ethanol production (10.4%) was obtained when cooked non-glutinous rice (100 g) and nuruk (30 sp/g) were mixed and added into pear juice (600 ml) with S. cerevisiae K-7 (5%) and fermented at $25^{\circ}C$ for 7 days and also its antihypertensive angiotensin I-converting enzyme (ACE) inhibitory activity was 57.2%. Addition of antihypertensive starchy materials into the mash was not affected in ACE inhibitory activity and total acceptability of KTPY.
