We have studied the physico-chemical change and pharmacological transformation of traditional herbal medicines with processing. Evodia fruit (EF) has processed for the purpose of detoxification and reduction of its bitter taste. There are various methods of processing EF in Oriental medicinal reference. Among them, we processed EF according to the method of Sang-han theory, the most famous medicinal reference. We processed EF with washing in hot water, and then dried. Processed EFs(PEFs) were prepared according to the above procedure through repetition of 1,3,5 and 7 times respectively. The contents of weight loss, water extract, diluted ethanol extract, ether extract, total ash, acid insoluble ash, alkaloids and limonin in non-processed EF (NPEF) and PEFs were examined. The weight loss, and contents of water extract and dilute ethanol extract in PEF showed decrease in proportion to increase of washing time, while the contents of ether extract, total ash and acid insoluble ash showed little change as compared with those of NPEF. And the content of evodiamine and rutaecarpine was not changed distinctly. However, the content of limonin decreased in the final processed material in proportion to increase of washing times with hot water. And the intense of bitter taste in PEF was also reduced. These results were ascribed to the flowing-out of the water-soluble portion. The biological activities of NPEF and PEF were also investigated. In the test of DPPH scavenging effect, xanthine oxidase inhibition effect and TBA-Rs effect, PEF was more effective than NPEF in vitro. Also, both NPEF and PEF showed potent analgesic and anti-inflammatory effects against in mice. Especially, PEF by 3 times washing with hot water was more effective than other PEFs. From these results, it is considered that PEF should be prepared by 3 times washing with hot water.

The purpose of this research was to investigate the effects of dried orange peel compound intaking and exercise training on the physique, body fat, and concentration bloodlipid in obese women. Ninety-seven volunteers(mean age 21.47 ${\pm}$ 1.47 yrs), all over 30% of body fat, agreed to Participate and were placed in 4 groups: dried orange peel compound intaking and exercise group(n=25), only exercise group(n=25), only dried orange peel compound intaking group(n=24), and control group(n=20). The subjects who joined this project were asked to take dried orange peel compound(2 times/day, 30 ml/time) or participate in exercise program(3 times/week, 70 min/day), depending on particular group for 12 weeks. They were tested on their height, weight, circumference of chest, abdomen, hip, and thigh, body fat%, total-cholesterol(TC), HDL-C, LDL-c, and triglyceride(TG) at the beginning and the end of the 12-weeks program. For data analysis, paired t-tests and ANCOVAs were used. The intaking of dried orange peel compound was influenced on weight, circumference of chest, abdomen, hip, and thigh, body fat%, HDL-C, LDL-C, and TG. The exercise participation had almost same effects on those dependent variables. Furthermore, the dried orange peel compound intaking along with exercise training was the most effective on those dependent variables among them. Therefore, these results indicate that dried orange peel compound intaking, like exercise, may be useful for controling weight, body fat, HDL-C, LDL-C, and TG.

As a part of searching tot the natural components which inhibit the skin aging and wrinkle formation, the $80\%$ methanolie extracts of 121 species of traditional herbal medicines used to treat lung and skin disease were investigated for their in vitro anti-oxidative activity against 1,1-diphenyl-2-picrylhydrazyl (DPPH) and superoxide radicals, and inhibitory activity against elastase. We selected 9 kinds of the traditional herbal medicines showing inhibitory activities of winkle formation. The effective concentrations of 9 candidates for anti-wrinke/skin firming activity was less than 0.1 mg/mL, and there is no toxicity to cell viability at these concentrations. Through analysis of human skin primary patch test data, the traditional herbal medicines represented non-irritant materials. We suggest that these 9 candidates with ability to help anti-wrinkle/skin firming may be useful for functional cosmetic materials.

In the previous results, we developed an effective products to apply as functional foods for overcome of radiation damage and reduction of side effects in radiotherapy. To verify the prevention of UVB-induced immunosuppression of immune cell function by HemoHIM, we studied on the mechanism of the skin immune function for the protection in UVB irradiation. In studies presented here, we showed that HemoHIM can prevent UVB-induced impairment of skin immune cell function by in vitro and in vivo assay. Exposure of freshly cultured murine dendritic cells (DCs) with IL-4/GM-CSF to UVB irradiation resulted in impairment of accessory function. This suppression could be prevented by addition of HemoHIM before or after to the cultures of UVB-irradiated DCs. We also tested the effects of HemoHIM on the suppression of contact hypersensitivity (CHS) treated oral or intraperitoneal administration. This UVB-suppressed CHS was prevented by administration of HemoHIM to UVB-irradiated mice. These results suggest that HemoHIM may prevent UVB-induced immune suppression in the skin.

Sixty $[(Duroc \times {Yorkshire)} \times {Landrace]}$ nursery pigs$(11.44\pm{0.13Kg}$ average initial body weight) were evaluated to know the effects of dietary Astragalus Membranaces and dried-onion meal complex(AO) on the growth performance and nutrient digestibility. There were three pigs per pen and five pens per treatment. Dietary treatments included 1) corn-SBM based diet(CON; basal diet), 2) AO 0.2(basal diet＋0.2% AO), 3) AO 0.4(basal diet＋0.4% AO) and 4) AO 0.6(basal diet＋0.6% AO). ADG was increased as the concentration of AO in the diets was increased(Linear effect, P =0.01). DM and N digestibilities were increased as the concentration of AO in the diets was increased(Linear effect, p =0.01). Thirty $[(Duroc \times {Yorkshire)} \times$ Landrace] growing pigs $(37.97\pm{0.54Kg}$ average initial body weight) were fed dietary treatments included 1) corn-SBM based diet(CON; basal diet) and 2) TRT(basal diet+0.3% AO). Pigs fed TRT diet were significantly(P<0.05) increased in ADG, ADFI and gain/feed compared to pigs fed CON diet. DM and N digestibilites of pigs fed TRT diets was higher than that of pigs fed CON diet(P<0.05). In conclusion, the results obtained from this feeding trial suggest that the dietary AO for nursery and growing pigs had improved growth performance and nutrient digestibility.

Higenamine, dl-1-( 4-hydroxybenzyl)-6, 7-dihydroxy-1 ,2, 3 ,4-tetrahydroisoquinoline has been synthesized and evaluated for hemodynamic actions using rabbits under pentobarbital anesthesia. Concentration-related fall of mean blood pressure was observed, where diastolic blood presure was significantly lowered at 10 ug/kg/min or above (p<.05), while the systolic blood pressure was slightly increased or unaffected, thereby, causing increment of pulse pressure. No significant change was occured in heart rate, however, carotid artery blood flow was significantly (p<.05) increased. These actions were inhibited with pretreatment of 0.3 mg/kg of propranolol, beta-adrenoceptor antagonist, 5 minutes before infusion of higenamine indicating that higenamine compete with propranolol for the so-called beta adrenergic receptor. As comparison, the same procedure was applied to isoproterenol as well, where typical antagonism of propranolol against isoproterenol was shown. From these findings the vasodilating and diastolic blood pressure lowing effects could be explained in terms of cardiac beta stimulating action, however, dopamine receptor activation could not be excluded because no significant changes observed in chronotropism.

Allium hookeri is a plant species native to India, Sri Lanka, Myanmar, and China. The plant is widely cultivated in Korea lately as a medicinal food item. This study was conducted to evaluate the effects of Allium hookeri (A. hookeri) on lipid metabolism in Type II diabetic mice (n=8/group, 5 groups). High fat diets with dextrin as a positive control (Dex), leaf (AL), root (AR), and fermented root (FAR) at 3% of diet were fed to all experimental mouse, respectively for 8 weeks. Body weight gain, liver and epididymal fat weights, and excreted fecal lipid levels were measured. Serum and hepatic lipid profiles were analyzed, and fat accumulation in liver was evaluated. In this study, body weight gain and epididymal fat weight were lower in the FAR group, while serum HDL-cholesterol level and excreted fecal total lipid and triglyceride levels were higher in AL or FAR groups. These results suggest that A. hookeri, specially fermented root can be a useful food item to control lipid metabolism in diabetic mice.

Korean mistletoe (Viscum album) extract has been found to posses immunostimulatory activity. In this study, Korean mistletoe extract, M11C (non-lectin components), was used to know whether this extract might activate mouse splenic macrophages to produce tumor necrosis $factor-{\alpha}\;(TNF-{\alpha}$) and might play a role in anticancer. To know the effect of M11C on the production of $TNF-{\alpha}$, the splenic macrophages were treated by the M11C, and then collected the supernatant (M11C stimulated splenic macrophage-conditioned media; MSCM). MSCM was analyzed for the $TNF-{\alpha}$ secretion by means of ELISA and immunoblotting, and mRNA expression was analyzed by RT-PCR. The S-180 murine sarcoma model was established to know the effect of M11C on the inhibition of tumor growth. M11C had the effect of $TNF-{\alpha}$ production from splenic macrophages performed by ELISA technique. This ELISA data was reconfirmed by immunoblotting assay. The effects of M11C on the expression of $TNF-{\alpha}$ mRNA from the macrophages was also shown. M11C also had the inhibitory effect of S-180 tumor growth. These data suggest that Korean mistletoe extract M11C may be used for an immunomodulator.

We analyzed the contents of polyphenol compounds, the antioxidant activity and the physiological activity to investigate the functional effects of extracts from Angelica dahurica by the reflux water extraction (RW), reflux ethanol extraction (RE) and pressure heating water extraction (PW). The content of phenolic compounds of PW was the highest at 156.30 mg/g, and those of RW and RE were 31.69 mg/g and 26.34 mg/g, respectively. The electron donating ability (EDA) were in the range of 30.56% $\sim$ 52.74% and superoxide dismutase (SOD) like activity were 10.96% $\sim$ 23.24% at 1,000 ${\mu}g/mL$. The nitrite scavenging ability of PW at pH 1.2 was 61.47%, higher than those of RW (16.81%) and RE (17.78%). The xanthine oxidase inhibitory were 90.91% and tyrosinase inhibitory rate of RE was the highest (51.71%) at the concentration of 5,000 ${\mu}g/mL$. All extracts were increased with increments of the extract concentrations.

The herb mixtures that are known to lower blood pressure were selected through oriental medical books and prescriptions and the physicochemical properties of their water extracts were analyzed to examine the possibility as functional food materials. The total yield of 28 water extracts was in the range of $5.33{\sim}36.71%$. Total phenolics and flavonoid content were $204.89{\sim}2543.29mg%\;and\;59.79{\sim}1430.55mg%$, respectively, and especially No. 2, 5, 9, 17, 18, 20, 22, and 26 showed high rates of above 800 mg%. Electron donating ability (EDA) was $7.81{\sim}98.18%$, and the samples that showed high values in EDA were similar to the samples with high values in total phenolics and flavonoid content. Phenolics and flavonoid compounds of the herbs are considered to perform a major role in antioxidation. Nitrite scavenging ability reached the highest at pH 1.2 ($11.70{\sim}96.47%$) and the lowest at pH 6.0 (below 12.77%), which indicates that nitrite scavenging ability decreases when pH increases.
