Purpose : Investigate the effects of Haeganjeon water extract (HGJ) on immobilization-stress or cold-stress in C57BL/6J mice. Methods : Male C57BL/6J 30 mice of weighting 18${\pm}$2g, were divided into sixs groups including the immobilization-stress group(5heads), after immobilization-stress HGJ oral administration(500mg/kg) groups(5heads), cold-stress group(5heads) and after cold-stress HGJ oral administration(500mg/kg) groups(5heads). then we observed changes in the serum histamine and corticosterone level and changes immune system. Results : HGJ decreased the serum level of histamine and corticosterone increased by immobilization-stress or cold-stress. HGJ inhibited the release of histamine from mast cells. In addition, HGJ enhanced the cell viability of thymocytes decreased by immobilization-stress or cold-stress and decreased DNA fragmentation of thymocytes increased by immobilization- stress or cold-stress. Also, HGJ increased the cell viability of splenocytes decreased by cold-stress and decreased DNA fragmentation of splenocytes increased by cold-stress. HGJ decreased the population of thymic CD4+ cells increased by immobolization-stress. HGJ increased the population of B220+ cells decreased by immobilization-stress and decreased the population of Thy1+ cells increased by immobilization-stress. Also, HGJ decreased the population of splenic CD4+ cells increased by immobolization-stress. HGJ enhanced the production of ${\gamma}-interferon$ decreased by immobilization-stress or cold-stress and increased the production of interleukin-4 decreased by immobilization-stress. Furthermore, HGJ enhanced the phagocytic activity decreased by immobilization-stress or cold-stress and enhanced the level of nitric oxide decreased by immobilization-stress or cold-stress. Conclusion : HGJ may be useful for the prevention and treatment of stress via suppression of serum histamine and corticosterone level and enhancement of immune response.

In order to investigate the effect of Naetakchungumsankamibang(NTCGS) water extract on the skin tumor induced by 3-MCA and immunological responses in mice, the cytotoxicity against SK-MEL-2 cells and total number of tumors induced by 3-MCA were measured. The numbers of WBC, platelets and RBC, plaque forming cells, hemagglutinin titer, hemolysis titer, carbon clearance, proliferation of splenocyte by thymidine uptake assay, splenic leukocyte by FACS analysis and $TNF-{\alpha}$ were also measured for the evaluation of the immunological responses. The results were obtained as follows: 1. In cytotoxicity against SK-MEL-2 cells, concentration inhibiting cell growth up to below $20\%$ of control was recognized at 1mg/ml of NTCGS. 2. In Inhibitory effect on the skin tumor induced by 3-MCA, the results showed a strong inhibitory effect of NTCGS. 3. In hematological changes in the tumor bearing mice, the numbers of WBC decreased significantly in NTCGS treated group as compared with control. 4. In hematological changes in the tumor bearing mice, the numbers of platelets increased significantly in NTCGS treated group as compared with control. 5. In hematological changes in the tumor bearing mice, the numbers of RBC increased with no significance in NTCGS treated group as compared with control. 6. Effects of the plaque forming cells in the tumor bearing mice, NTCGS treated group exhibited a significant effect compared with control. 7. In terms of the effects on hemagglutinin titer, NTCGS treated group showed higher level than control, without significance. 8. In terms of the effects on hemolysis titer, NTCGS treated group showed higher level than control, without significance. 9. In terms of the effects on phagocytic index K in Balb/C mice, NTCGS treated group showed significant difference from control. 10. In terms of the effects on proliferation of splenocyte by thymidine uptake assay, NTCGS showed significant effect at the concentration of 0.5mg/ml. 11. In terms of the effects on splenic leukocyte of Balb/C mice by FACS analysis, NTCGS treated group showed significantly higher level of helper T cell, B cell and macrophage than in control. 12. In terms of the effects on the secretion of $TNF-{\alpha}$, the treated group showed significant effect at the concentration of 1mg/ml of NTCGS. Based on the results summarized above, NTCGS is considered to have antitumor activity and immunological responses against skin tumor, and to be usable fur the treatment.

Water extract of Coix locrvmn seeds (Co-Ex) was separated into several components; dissolved with Tris-Cl buffer and the supernatant (WC 1), ammonium sulfate treatment supernatant (WC2) and the pellet nvc31,9AE column chromatography of WC 1 and the peak portions; WC4, WCS and WC6. Murine peritoneal macrophages in DMEM containing 10% heat-inactivated FCS were infected with tachyzoites of ToxopIQsmc gondii, RH strain, in uifo. By adding modulators such as Co-Ex, WC 1,2,3,4.5,6 and LPS or IFN-γ for 24 hrs . toxoplasmastatic activity of macrophages was examined in relation to nitrite production. Nitrite production of macrophages was enhanced especially in the series of WC2, WC1 and the combination sample (WC1 + WC2 + WC3) by order than other components or fractions (WC4, WC5, WC6) tested . Toxoplasmastatic actions such as percentage of the inacrophages infected by T. gonnii and fold increase of T gondii in macrophages showed retroverse relations with the amount of nitrite production; i.e. as nitric oxide (NO) increased the phagocytic index of macrophages and the fold increase of tachyzoites in macrophages decreased . Nitrite (NO-2) production was increased by adding IFN-γ in all cases together with enhancement of biostatic effects. Through the results obtained, it is speculated that some components other than the non-proteinous and defatted components in Coix lacrwmn seeds may contribute to activate macrophages through induction of NO for the biostatic activity.

The water-soluble materials extracted from fruit bodies and mycelium of H. erinaceum were prepared. In-vitro anticancer activities on cancer cells and In-vivo proliferation effect on mouse peritoneal exudate cell and spleen cell of samples were investigated. Also, nitric oxide (NO) generation of peritoneal exudate cell, IL-2 production capacity of spleen cells and phagocytic activity of peritoneal macrophages were examined. The water extracts of H. erinaceum suppressed the proliferation of cancer cell (HeLa, Raw264.7, Jurkat, KATO3, EL4, LyD9) with concentration-dependent. The water extract from fruit body showed better suppression effect than that from mycelium in most of cancer cells used. The anticancer effect of water extract of fruits body in the range of 0.01 and 10 mg/ml for Raw 264.7 and EL4 cell lines were the same as the Taxol with one thousandth equivalent of fruit body concentration. Water extracts of fruit body and liquid-cultured products of H. erinaceum induced nitric oxide (NO) generation of peritoneal exudate cell and increased NO generation by stimulus of lipopolysaccharide. Water extracts alone did not induce the proliferation and IL-2 production capacity of spleen cells. However, spleen's proliferation and IL-2 production were induced significantly by the addition of lipopolysaccharide and Con A (concanavalin A) or Con A alone, and the effectiveness of mycelium extract with water were more active than those from fruit body.

Two-day-old chickens{\;}and{\;}mallards were orally inoculated with one of % doses varying from $2{\;}{\times}{\;}10^2{\;}to{\;}2{\;}{\times}{\;}10^6$ of C. bailevi oocysts per individual. Generally, the more oocysts Inoculated were, the longer the patent periods were, and the more oocysts shedding were. Meanwhile increasing the inoculative dose, the prepatent periods were shortened except that mallards inoculated with $2{\;}{\times}{\;}10^2and{\;}2{\;}{\times}{\;}10^3$ oocysts foiled to produce the oocysts. The more parasites involving oocysts appeared from the chicken in comparison to the mallard. In the chickens challenged with a single dose of $2{\;}{\times}{\;}10^6$ oocysts, a small number of oocysts were detected from feces on days 4-14 after challenge infection (ACI) in all of carrageenan administered groups and in the control groups inoculated with $2{\;}{\times}{\;}10^2{\;}and{\;}2{\;}{\times}{\;}10^3$ oocysts. In the mallards, a few oocysts were also recognized on days 5-15 ACI in all of carrageenan treated groups and in the control groups inoculated with $2{\;}{\times}{\;}10^2,{\;}2{\;}{\times}{\;}10^3{\;}and{\;}2{\;}{\times}{\;}10^4$ oocysts. Just prior to challenge infection, phagocytic activity of peritoneal macrophages (Me) and the number of peripheral Mc in both birds were significantly decreased in the carrageenan treated groups as compared to the control groups. Mild challenge inection in both birds denoted that the immunogenicity of C. bailelli to the birds was very strong, despite MB blocker carrageenan administration.

5-Aminolevulinic acid phosphate (5-ALA-p) is a substance obtained by eluting 5-ALA (a natural delta amino acid) with aqueous ammonia, adding phosphoric acid to the eluate, and then adding acetone to confer properties suitable for use in photodynamic therapy applications. However, its pharmacological efficacy, including potential mechanisms of antioxidant and anti-inflammatory reactions, remains unclear. This study aimed to investigate the effects of 5-ALA-p on oxidative and inflammatory stresses in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. Our data showed that 5-ALA-p significantly inhibited excessive phagocytic activity via LPS and attenuated oxidative stress in LPS-treated RAW 264.7 cells. Furthermore, 5-ALA-p improved mitochondrial biogenesis reduced by LPS, suggesting that 5-ALA-p restores mitochondrial damage caused by LPS. Additionally, 5-ALA-p significantly suppressed the release of nitric oxide (NO) and pro-inflammatory cytokines, such as tumor necrosis factor α (TNF-α), interleukin (IL)-1β, and IL-6, which are associated with the inhibition of inducible NO synthase and respective cytokine expression. Furthermore, 5-ALA-p reduced the nuclear translocation of nuclear factor-kappa B (NF-κB) and inhibited phosphorylation of mitogen-activated protein kinases (MAPKs), indicating that the anti-inflammatory effect of 5-ALA-p is mediated through the suppression of NF-κB and MAPK signaling pathways. Based on these results, 5-ALA-p may serve as a potential candidate to reduce inflammation and oxidative stress.
