The effect of Herricium erinaceus on the mutagenicity in salmonella assay and quinone reductase activity in hapalclc7 cells were studied. Antimutagenic as evaluated by Ames test, the extract and fractions of JHerricium erinaceus had no effects on the mutagenicity by themselves. However, methanol extract and fractions from Hericium erinaceus showed strong inhibitory effect on the mutagenesis induced by N-methyl -N'-nitor-N- nitroso-guanidine (MNNG) and benzo(a)pyrene (B(a)P). Among the solvent fractions of methanol extract, the hexane fraction, the chloroform fraction and the ethylacetate fraction exhibited stronger inhibitory activity against MNNG and B(a)P induced mutagenesis than butanol and water fractions. The methanol extract, the extract, the chloroform and the ethylacetate fractions of Hericium erinaceus induced the activity of quinone reductase, an anticarcinogenic marker enzyme, in murine hepalclc7 cells while the others did have little effect on the enzyme activity.

In recent years, Hericium erinaceus became famous for comsumer because it contains some materials to assist in human health. This study was carried out to find the difference of occurring pattern of H. erinaceus by pinheading induction methods. Harvest period of T1, T2 treatments were longer than T3~T6. All treatments fresh weights were not significantly different, but T3, T6 treatments's dry weight in 2nd flush were lower than others. T5 treatment's 2nd flush's regeneration rate was the highest than others and looks best quality. Therefore, it is suggested that pinheading induction method would be changed not T1, T2 treatment which were used some farm as Pluerotus ostreatus cultivation, but to scratch surface method which is T5 treatment for cultivation of high quality H. erinaceus.

Alcohol concentration in the blood was effectively decreased by extracts from Hericium erinaceum hypha cultivated with Artermisia capillaris medium(HEAC), Hericium erinaceum hypha and Artermisia capillaris after dirnking. Also, the activities of alcohol dehydrogenase and acetaldehyde dehydrogenase in the blood was studied. As a result of testing an alcohol concentration in the blood, the alcohol in the blood was not detected after 170 min, in case of HEAC and after 210 min, in case of Hericium erinaceum. Compared to control, each activities of alcohol dehydrogenase of HEAC and Hericium erinaceum hypha was showed up to 154% and 148% respectively. The activities of the acetaldehyde dehydrogenase of both extracts from HEAC and Hericium erinaceum was maintained in the range of 104 to 110% compared to control. In conclusion, such extracts represent significant effect to facilitate decomposition of alcohol.

We investigated inhibitory effects of Hericium erinaceus on the growth of cancer cells and the expression of cell cycle regulators, cyclins. Anticancer effects of Hericium erinaceus extract and fractions against cancer cell lines including HepG2 and HT29 were investigated. The methanol extract, the hexane fraction, the chloroform fraction and the ethylacetate fraction of Hericiu erinacew inhibited growth of cancer cells but they had no effect on the cytotoxicity of normal human liver cells under the same conditions. As shown by western blot analysis, the expression of cyclin B1 known as cell cycle regulator was markedly decreased after treatment with Hericium erinaceus extract in HepG2 cells. These results suggest that antiproliferative effect of Hericaum erinaceus extract is associated with markedly decreased expression of cyclin B1.

The purpose of this study was to investigate the antioxidant, nitrite scavenging, angiotensin-converting enzyme (ACE), and tyrosinase inhibition activities of ethanol extracts from Hericium erinaceus (HE) cultured in Angelica keiskei (AK) and Angelica keiskei pomace (AKP). Antioxidant activities of the HE, AK, AKP, HE+AK, and HE+AKP extracts were higher than that of control, but lower than those of BHT and Vit C. Tyrosinase inhibition activity was the highest in AKP+HE extract (90%), whereas those of HE, AK, AKP, and AK+HE extracts were about 57, 61, 82, and 78%, respectively. Nitrite scavenging abilities of various samples were above 80% at pH 1.2, and there was no significant difference between the HE, AK, AK+HE, and AKP+HE extracts at pH 3.0, excepting the AKP extract. ACE inhibition activity was the highest in AKP extract (60%), whereas those of HE, AK, AK+HE and AKP+HE extracts were about 42%, 50%, 35% and 40%, respectively. These results suggest that H. erinaceus cultured in AK and AKP may be used as a raw material for functional foods, and food additives, as well as in the cosmetic industry as a natural source of bioactive compound after further investigation in vivo.

This study was carried out to investigate the effects of Hericium erinaceum (HE) powder and extract on the quality characteristics of noodles. The water binding capacity of the HE powder was higher than that of pure wheat flour. Gelatinization temperature of HE powder-wheat flours gradually were increased and initial viscosity at $95^{\circ}C$, viscosity at $95^{\circ}C$ after 15 min and maximum viscosity of those composites were decreased, as measured by a amylograph. The noodles showed decreased L values and increased a and b values with increasing HE powder in the wheat flour composite. The mechanical properties of the control cooked noodles showed the highest hardness, which decreased with the addition of HE powder. Springiness, cohesiveness, and gumminess decreased with increasing amounts of added HE powder. While the higher adhesiveness of noodles increased with more preferred than the control, and considerably the greatest overall acceptability of noodles was for those containing 2% HE powder.

Macrophage-derived nitric oxide (NO) plays an important role in immune responses. Overproduction of NO by inducible nitric synthase(iNOS) is known to be closely correlated with the pathology of a variety of diseases and inflammations. This study investigated the inhibitory effect of extract from various mushrooms(Phellinus linteus(PL), Inonotus obliquus(IO), Sarcodon aspratus(SA), Hericium erinacium(HE), and Russula cutefracta(RC)) on NO production and its molecular mechanism in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. Among the mushrooms, HE extracts exhibited the strongest NO-inhibition activity. It was also found that HE extract inhibited LPS-induced iNOS and COX-2 expression in RAW264.7 cells. The present results give the understanding of biological activities of mushrooms and encourage their application for supplements and cook.

To utilize the abandoning byproducts after manufacturing fresh vegetable juice, Hericium erinaceum (H. erinaceum) was cultured using Angelica keiskei (AK) and the byproducts of Angelica keiskei (BAK) as anutrient and the chemical composition of the culture extract was analyzed. When H. erinaceum was cultured using culture media of AK and BAK, it showed 107{\sim}112 mm of growth during 40 days. The moisture contents of AK and BAK extracts were 94.36 and 97.36%, respectively; however, those of extracts of H. erinaceum cultured in AK and BAK decreased to 90.95 and 94.20%, respectively. Reversely, other chemical compositions were increased. The vitamin A content of AK extract was 20.78 IU/100 mL and was higher than those of other extracts. However, vitamin A was not detected in extracts of H. erinaceum cultured with AK and BAK. In contrast, vitamin $B_2$ and C in the extracts of H. erinaceum cultured were higher than those of AK and BAK. Total ash content including Fe, P, Mg, and Ca increased in the extracts of H. erinaceum cultured when compared with AK and BAK extracts. Total amino acid content was also higher in the extracts of H. erinaceum cultured (231.08 and 372.25 mg%) than those in the extracts of AK (177.17 mg%) and BAK (149.99 mg%).

This study was carried out to investigate the anti-oxidative and anti-inflammatory actions of Hericium erinaceus mycelia in BALB/C mice injected with lopopolysaccharide (LPS), called endotoxin. Mice (6 weeks of age) weighing approximately $24.73\pm0.11$ g were divided into 5 groups and were fed on the experimental diets containing Hericium erinaceus mycelia powder (HMP) for 1 week. Experimental groups were NC (normal control), HMP-C (HMP control), LC (LPS control), HMP 3%, and HMP 10%. Endotoxin shock was induced by intraperitoneal injection of LPS (100 mg/kg BW). NC and HMP-C groups were injected with saline solution (100 mg/kg BW). Food efficiency ratio were significantly (p<0.05) decreased in the HMP supplementation groups. Total fat and $\beta$-glucan excretion were higher in HMP supplementation groups than NC and LC groups, while plasma TG level was not different among groups. Plasma ALT levels were significantly (p<0.05) lower in the HMP supplementation groups than in LC group at 8 hr after LPS injection, while tumor necrosis factor-$\alpha$ and interleukine-6 levels of plasma were not different among groups. Hepatic superoxide dismutase, glutathione-reductase (GSH-red), and glutathione-peroxidase activities were higher in the HMP supplementation groups than in LC group at 4 hr after intraperitoneal injection of LPS. Hepatic GSH levels and protein expression of GSH-red was significantly (p<0.05) higher in the HMP supplemented groups than in LC group at 1 hr, 4 hr and 8 hr after LPS injection. From the above results, it is concluded that Hericium erinaceus mycelia may ameliorate hepatic oxidative stress by LPS through the elevation of hepatic glutathione level and antioxidant enzyme activities, which support the hepatoprotective effect of Hericium erinaceus mycelia.
