In this study, the effects of intake of Acer mono Max. seed oil, and Magnolia denudata seed oil on the lipid levels of mouse blood were compared to those of commercially available vegetable oils. Five ICR mice were each fed a corn oil, Acer mono Max. seed oil, and Magnolia denudata seed oil supplemented diet for a total of 8 weeks. The serum profiles of mice fed Acer mono Max. seed oil and Magnolia denudata seed oil were high in palmitic acid, oleic acid, and linoleic acid. The saturated fatty acid contents of mice fed Acer mono Max. seed oil and Magnolia denudata seed oil were 3.95% and 0.88%, whereas the unsaturated fatty acid contents were 8.71% and 4.60%, respectively. The liver and spleen weights of mice fed Acer mono Max. seed oil were higher than those fed corn oil (p<0.05). Total cholesterol level was highest in mice fed Acer mono Max. seed oil (p<0.05), whereas there were no significant changes in the cholesterol levels of mice fed Magnolia denudata seed oil and corn oil. The HDL-cholesterol levels in mice fed Acer mono Max. seed oil ($175.80{\pm}27.66mg/d{\ell}$) and in those fed Magnolia denudata seed oil ($145.20{\pm}19.10mg/d{\ell}$) were higher compared to those of mice fed corn oil (p<0.05). In conclusion, there were no significant differences in fatty acid composition between mice fed Acer mono Max. seed oil and Magnolia denudata seed oil. Future study on the antioxidant effects of seed oils should be carried out.

Effect of combined preparation (DWP715) containing Alaska pollack extract, maltol, ascorbic acid and nicotinamide on decreasing of blood alcohol was evaluated in human blood. Treatment of DWP715 prior to administration of 25% alcohol (100 mL) decreased alcohol concentration in blood and showed significant difference after 2 hours. The pharmacokinetic parameters such as area under the concentration-time curve (AUC), $C_{max},\;T_{max}\;and\;T_{1/2}$ were also decreased and delayed when compared with control values. Effects of DWP715 on anti-fatigue and anti-oxidation activities were also studied in the restraint stress model using various parameters (GOT, GPT, LDH values and organ weights) on mild condition and examined through the content of lipid peroxide induced by 2% $CCl_4$ in mouse livers. While GPT level, thymus and adrenal weight were not influenced by DWP715 dosing, LDH, GOT level and spleen weight used as a parameter against fatigue and stress states were recovered almost to the nomal level. Furthermore, lipid peroxidation due to $CCl_4$ was significantly inhibited by DWP715 treatment. These results suggest that DWP715 seems to metabolize the blood alcohol rapidly and to restore the damaged liver and fatigue conditions which was caused by alcohol metabolism to normal condition.

Recently Atopic Dermatitis(AD) is increasing along with allergic disease. At present, there is no infallible cure for AD. Then AD patients undergo great suffering. This study is carried out to see whether or not the administering Danggwieumja(DG) along with Samhwangseje-gamibang(SG} as a medicine for external aplication, is effective in treating atopic dermatitis. To examine the effectiveness of the above prescription, the author made an observation of diverse immune responses. through the model of NC/Nga atopic mice. Results provided evidence that the DG administration along with SG can be used as a treatment means to atopic dermatitis. The results are as follows: The extent of Clinical skin severities in 13 and 16 week old NC/Nga mice treated with DG and SG, were reduced by 50.9%, 53.9% respectively, compared to the control NC/Nga mice with no drug treatment. IgE, IL-4, IL-5, IL-6, IgM and IgG1 levels in the serum of the NC/Nga mice treated with DG and SG were significantly decreased compared to those of the untreated control mice. In contrary, to the $IFN-{\gamma}$ level, significantly increased. The spleen weight of the NC/Nga mice treated with DG and SG significantly decreased compared to those of the untreated control mice. CCR3 gene expression in the skin tissue of NC/Nga mice treated with DG and SG were highly decreased, and the IL-6 expression significantly decreased, and the $IFN-{\gamma}$ gene expression increased compared to those of the untreated control mice. Histological observation of the ear and dorsal skin tissue of the NC/Nga mice treated with DG and SG, showed that the extents of inflammation and infiltrated immune cells in the epidermal tissue and dermis, were highly reduced compared to those of the untreated control mice. In the model inducing COX-2 activity in RAW 264.7 cell, the denser DG became, the more COX-2 activity was inhibited, compared to those of the untreated control group. $IL-1{\beta}$, and $TNF-{\alpha}$, IL-6 gene expression in RAW 264.7 cell with DG, significantly decreased, compared to those of the untreated control group. According to the assessment of cell toxicity in L929 cell, the rate of cell multiplication increased by 3% in consistency to 100ppm of DG compared to the untreated control group and in more than the 200 ppm consistency, cell toxicity was occurred.

DW-166HC ($^{166}$Holmium-chitosan) is a complex of $^{166}$Ho, $\beta$- and $\gamma$-ray emitter, and chitosan, a polymer of glucosamine, with radiotherapeutic potential. The current study was performed to determine the acute toxicities of $^{165}$Ho-chitosan in mice by two different routes of administration. The both sex mice were given a single intravenous bolus injection of $^{165}$Ho-chitosan complex at doses of 12, 10, 6, 5 and 4 mg/kg or subcutaneous administration at doses of 600, 500, 400 and 300 mg/kg. Chitosan was dosed to control animals as 16 and 800 mg/kg, intravenously and subcutaneously, respectively. The doses of $_{165}$Ho-chitosan complex were expressed as $_{165}$holmium nitrate pentahydrate and the ratio of $^{165}$Ho$(NO_3)_3$).$5H_2O$ to chitosan was 3/4 Severe convulsion and respiratory failure were followed by death within 10 min after intravenous dosing. Transient unilateral hindlimb hypokinesias were found in two mice of 5 mg/kg dosing group during the study period. No abnormalities were observed during the necropsy of survived animals in intravenous dosing group. Only one male animal was found dead in 500 mg/kg subcutaneously dosed group. Alopecia with or without cutaneous ulcer were found in most mice including control animals. During necropsy, omental adhesion was observed in all dose ranges and enlarged spleen was found in several animals including control group. It is suggested that the acute intravenous >).$LD_{50}s$ for male and female mice were 4.90 and 6.03 mg/kg, respectively. The lowest lethal dose in male was 500 mg/kg by subcutaneous administration.

A Recent discovery of surface antigens in cells has led to the success of quantitative measurement of T-cell subpopulations, and this has especially opened the way for an epoch-making development in the understanding and classification of cellular immune mechanisms. It is known that phenotypes of T-cell subpopulations exist in many forms according to the variation of species or animal experimental models. In Korea, Clonorchis sinensis still gives rise to public concern as it infects more than eighty million people and threatens the public by causing cirrhosis of the liver, or liver cancer when liver infection becomes prolonged and chronic. Up until now there has been much progress in research and improvement in the classification system of Clonorchis sinensis in the area of humoral immunity, but as for research in the area of cellular immune mechanisms, there is almost none. Knowing all these circumstances, the authors delved for the characterization of Iymphocyte subpopulations with mice as Clonorchis sinensis in the area of cellular immunity, and obtained the following results. That is, we injected Clonorchis sinensis antigens mixed in Freund's ajuvant solution intraperitoneally in mice and measured the T-cell subpopulation characterization of spleen lymphocytes with flow cytometry. The results of these measurements showed that CD2, CD5 and CD8 decreased early following injections but then in-creased again seven weeks after the injections. CD4, however, showed a slight increase shortly after the injection but then a fair increase seven weeks after the injection.

Among the various receptor molecules discovered so far the ${\beta}$2-adrenergic receptors have been regarded as excellent model systems for the so called 7 transmembrane helix receptor and have been the focus of extensive studies. For the analysis of receptor structure and function a monoclonal antibody plays a crucial role, thus providing useful tools for the study of receptor. However, because of the minute quantity of receptor molecules which could be obtained from natural sources, the generation of specific monoclonal antibody against receptor molecules from the purified receptors has been regarded as virtually impractical in consideration of cost and experimental times. The purpose of the present study was to generate and characterize a monoclonal antibody against human ${\beta}$2-adrenergic receptor. For the production of antibody, C-terminal regions of the human ${\beta}$2-adrenergic receptor was produced as a fusion protein with Glutathion S-transferase (GST) in E. Coli. The expression of the fusion protein was identified by SDS-PAGE and Western blot using monoclonal anti-GST antibody. The fusion protein was purified to an apparent homogeniety by affinity chromatography with Glutathion Sepharose CL-4B and used as an antigen for the immunization of BALB/C mice. The Production of monoclonal antibody was achieved by fusion of the immunized spleen cells and SP/2-0 myeloma cells. Positive hybridomas were screened by ELISA and were cloned by two consecutive rounds of limiting dilution. The monoclonal antibody produced in this study (mAb${\beta}$C02) was IgM type and purified by immunoaffinity chromatography using anti-mouse IgM agarose as an affinity matrix. MAb${\beta}$C02 showed strong and specific immunoreactivity against both the fusion protein and human ${\beta}$2-adrenergic receptor in ELISA and Western blot. The molecular weight of immunoreactive band was 64 kDa and exactly coincided with the previously reported molecular weight of ${\beta}$2-adrenergic recepters. The results of the present study suggest that mAb${\beta}$C02 may be used for the study of receptor function and regulation in normal or nonphysiological status.

TIAF1 is a TGF-${\beta}$1-induced anti-apoptotic factor that plays a critical role in blocking TNF (tumor necrosis factor) cytotoxicity in mouse fibroblasts and participates in TGF-${\beta}$-mediated growth regulation. In this study, we obtained the full-length cDNA sequence of the porcine TIAF1 gene. Real-time PCR further revealed that the TIAF1 gene was expressed at the highest level in liver and kidney with prominent expressions detected in uterus, and lower levels detected in heart, spleen, lung, stomach, small intestine, skeletal muscle and fat of Large White pigs. Sequence analysis indicated that a 6 base-pair deletion mutation existed in the exon of the TIAF1 gene between Meishan and Large White pigs. This mutation induced deletion of Gln and Val amino acids. PCR-RFLP was used to detect the polymorphism in 394 pigs of a "Large White${\times}$Meishan" $F_{2}$ resource population and four purebred pig populations. The frequencies of the A allele (with a 6 bp deletion) were dominant in Chinese Meishan and Bamei pigs, and the frequencies of the B allele (no 6 bp deletion) were dominant in Large White and Landrace pigs. Association analyses revealed that the deletion mutation had highly significant associations (p<0.01) with meat marbling score of the thorax-waist longissimus dorsi (LD) muscle (MM1) and intramuscular fat percentage (IMF), and significant associations (p<0.05) with carcass length (CL). The results presented here supply evidence that the 6 bp deletion mutation in the TIAF1 gene affects porcine meat quality and provides useful information for further porcine breeding.

Oral administration of antigen has long been considered as a promising alternative for the treatment of chronic autoimmune diseases including rheumatoid arthritis (RA), and oral application of type II collagen (CII) has been proven to improve pathogenic symptoms in RA patients without problematic side effects. To further current understandings about the immune suppression mechanisms mediated by orally administered antigens, we examined the changes in IgG subtypes, T-cell proliferative response, and proportion of interleukin (IL)-10 producing Th subsets in a time course study of collagen induced arthritis (CIA) animal models. We found that joint inflammation in CIA mouse peaked at 5 weeks after first immunization with CII, which was significantly subdued in mice pre-treated by repeated oral administration of CII. Orally tolerized mice also showed increase in their serum level of IgG1, while the level of IgG2a was decreased. T-cell proliferation upon CII stimulation was also suppressed in lymph nodes of mice given oral administration of CII compared to non-tolerized controls. When cultured in vitro in the presence of CII, T-cells isolated from orally tolerized mice presented higher proportion of $CD4^+IL-10^+$ subsets compared to non-tolerized controls. Interestingly, such increase in IL-10 producing cells were obvious first in Peyer's patch, then by 5 weeks after immunization, in mesenteric lymph node and spleen instead. This result indicates that a particular subset of T-cells with immune suppressive functions might have migrated from the original contact site with CII to inflamed joints via peripheral blood after 5 weeks post immunization.
