C-22 is one of health food made in Han Kook Shin Yak. For studying its antitumor activity, the 50% ethanol extract from C-22 was tested on BDF1 mice bearing LLC tumor cell by Teruhiro’s method. The samples were intraperitoneally injected to mice once a day with a daily dose of 50, 100, and 200 mg/kg for 14 consecutive days. Taxol was used as positive control with a dose of 50 mg/kg. As a result, the C-22's extracts dose dependently inhibited the tumor volume with the IRTV values of 28.7, 46.7, 58.9% and the IRTW values of 28.1, 46.0, 57.8% in 50, 100, and 200 mg/kg, respectively, while the Taxol showed antitumor activity with IRTV and IRTW values of 68.5 and 67.3% in 50 mg/kg. No loss of body weight was observed at any samples. This data suggested that the C-22's antitumor activity was enough to use as a cancer chemopreventive agent, and it will be used for preventing cancer as health food.

A protein-polysaccaride fraction Kp(53.9% polysaccharide, 14.2% protein) was separated from the shake-cultured mycelia of a basidiomycetous fungus, Phellinus linteus, and its antitumor activity against sarcoma 180 in ICR mice was investigated. When administered after the tumor implantation, Kp exerted antitumor activity by inhibiting the growth of the sarcoma 180 solid tumor by 71.5% and increasing the life span of the sarcoma 180 ascitic mice by 51.5% at 100 mg/kg. In pretreatment tests, in which Kp was administered once daily for 9 days before the tumor implantation, Kp inhibited the growth of the solid and ascites form of sarcoma 180, respectively, by 35.4% and by 80.3% at 100 mg/kg. However, Kp showed no in vitro cytotoxic activity against a murine leukemia L1210 and a human gastric tumor SNU.1 upto the concentration of $200\;{\mu}g/ml$. From these results, it is clear that the antitumor activity of Kp is exerted through its immunomodulating activity on the host's immune system.

The immunomodulating activity of Kp, an antitumor protein-polysacchanide preparation from the shake-cultured mycelia of Phellinus linteus, was investigated in ICR mice subcutaneously implanted wit $1\times10^6$ cells of sarcoma 180. The mice were intraperitoneally administered with Kp at a does of 100 mg/kg once daily for five consecutive days starting from 24 hrs after the tumor implantation. Ten days after the last injection, the mice were immunized with $1\times10^7$ or $4\times10^8$ sheep red blood cells (SRBC) and five days later, the antibody-forming immune response were assessed by direct hemolytic plaque assay. To an immunization does of $1\times10^7$ SRBC, the Kp-treated mice elicied a successful humoral immune response despite the turmor-burden and produced $259\times10^3$ plaque-forming cells (PFC)/spleen, while the corresponding tumor-bearing control mice showed virtually no reponse $(2.0\times10^3$ PFC/spleen) (the stimulation index=129.5). However, to an immunization dose of $4\times10^8$ SRBC, both of the control mice and Kp-treated mice showed almost the same level of strong humoral immune response. From these data it is clear that Kp effectively restores the humoral immune response of the turmor-bearing ICR mice.

Previous work demonstrated that an ethanol extract (HS0608) of a mixture of three medicinal plants of Curcuma longae radix, Phellinus linteus, and Scutellariae radix markedly inhibits $A{\beta}$ (25-35)-induced neurotoxicity. The present study was performed to further verify the neuroprotective effect of HS0608 on oxidative and ischemic cerebral injury using cultured rat cortical neurons and rats. Exposure of cultured cortical neurons to $100\;{\mu}M$ hydrogen peroxide ($H_2O_2$) induced neuronal apoptotic death. At $10-100{\mu}g/ml$, HS0608 inhibited neuronal death, elevation of intracellular calcium concentration ($[Ca^{2+}]_i$), and generation of reactive oxygen species (ROS) induced by $H_2O_2$ in primary cultures of rat cortical neurons. In vivo, HS0608 prevented cerebral ischemic injury induced by 2-h middle cerebral artery occlusion (MCAO) and 24-h reperfusion. The ischemic infarct and edema were significantly reduced in rats that received HS0608 (200 mg/kg). These results suggest that the anti-oxidative properties of HS0608 may be responsible for its neuroprotective effect against focal cerebral ischemic injury and that HS0608 may have a therapeutic role in neurodegenerative diseases such as stroke.

The present study investigated an ethanol extract (HS0608) of a mixture of three medicinal plants of Curcuma longae radix, Phellinus linteus, and Scutellariae radix for possible neuroprotective effects on neurotoxicity induced by amyloid $\beta$ protein ($A{\beta}$) (25-35) in cultured rat cortical neurons and antidementia activity in mice. Exposure of cultured cortical neurons to $10\;{\mu}M$ $A{\beta}$ (25-35) for 36 h induced neuronal apoptotic death. At $1-50\;{\mu}g/m{\ell}$, HS0608 inhibited neuronal death, elevation of intracellular calcium concentration ($[Ca^{2+}]_i$), and generation of reactive oxygen species (ROS) induced by $A{\beta}$ (25-35) in primary cultures of rat cortical neurons. Memory loss induced by intracerebroventricular injection of ICR mice with 15 nmol $A{\beta}$ (25-35) was inhibited by chronic treatment with HS0608 (25, 50 and 100 mg/kg, p.o. for 7 days) as measured by a passive avoidance test. From these results, we suggest that the antidementia effect of HS0608 is due to its neuroprotective effect against $A{\beta}$ (25-35)-induced neurotoxicity and that HS0608 may have a therapeutic role in preventing the progression of Alzheimer's disease.

In this study, we analyzed and quantified the amounts of bioactive phenolic constituents, xanthotoxin (1), oxypeucedanin (2), and imperatorin (3) in each part of the root of Angelica dahurica by HPLC, which validated by ICH guide lines comparing the linearity, intra day precision, inter-day precision. As a result, the amount of imperatorin 2.96% in the rootlet was two fold higher than that of the main root 1.32%. On the other hand, the amounts of xanthotoxin and oxypeucedanin in the rootlet showed similar to those of main root. In addition, the cortex of root is more plentiful of three consitituents (0.66%, 0.53%, and 1.85%) than those of xylem (0.29%, 0.05%, and 0.07%). These results show that the rootlet and cortex contain a large amount of bioactive phenolic constituent including xanthotoxin, oxypeucedanin, and imperatorin than other parts of the root.

To produce a thermostable cyclodextrin by using thermotolerant cyclomaltodextrin glucanotransferase(CGTase), a thermophilic and alkalophilic bacterium isolate, designated B-13 showing the highest CGTase activity was isalated from natural sources and identified as Bacillus cereus B-13 based on the morphological and physiological characteristics, and 16S rRNA sequence. The maximal CGTase activity (130 U/ml) was obtained when Bacillus cereus B-13 was cultured in SYC medium containing 2.0% soluble starch, 1.0% yeast extracts, 1% corn steep liquor and 1% $Na_2CO_3$ (pH 8.5) at $50^{\circ}C$ for 24 h and about 80% of maximal activity was also showed in he culture broth of $60^{\circ}C$ for 18 h. Optimum reaction temperature and pH of the partial purified CGTase for soluble starch were $65^{\circ}C$ and pH 8.5-9.0 respectively. The partial purified CGTase were also stable below $80^{\circ}C$ and pH 5.0-10.0. When 1% soluble starch was digested with the partial purified CGTase, the yield of cyclodextrin was 49%.
