  • Cytochrome P-450(CP-450) is one of the three components of the liver microsomal enzyme system which hydroxylates fatty acids, hydrocarbons and a variety of drugs and other foreign compounds. Female Balb/c mice were immunized with purified polychlorinated bipheny(PCB)-induced CP-450 LMII. The spleen cells derived from immunized mice were fused with $SP^2$ myeloma cells using polyethylene glycol(PEG 3500). The hybrid cells were selected by hypoxanthine-aminopterine and thymidine(HAT) medium and the culture fluid were screened by enzyme-linked immunosorbent assay to CP450 LMII. The hybrid cess(${\times}10^7$) were innoculated into intraperitoneal cavity of Balb/c mice for the purpose of production of ascitic fluids. Monoclonal antibody(Mab) was purified from ascitic fluid by DEAE cellulose ion exchange chromatography and $I^{125}$-labeled Mab was also confirmed by autoradiography and SDS-polyacrylamide gel electrophoresis (MW : 55,000 and 110,000).

  • The roots of Rumecis Radix have been used for the treatment of heat phlegm, jaundice, constipation, scabies and uterine hemorrhage. The aim of this study was to confirm whether Rumecis Radix water extract (RJWE) has a preventive effect on the development of atopic dermatitis (AD) in 2,4-dinitrochlorobenzene (DNCB)-applied BALB/c mice. Oral administration (12.5 mg/kg, 25 mg/kg) and topical application (0.5 mg/mouse, 1.0 mg/mouse) of RJWE decreased the development of AD-like skin lesions, ear swelling, spleen weight and total serum IgE. RJWE significantly also inhibited the infiltration of mast cells in the dorsal skin. Furthermore, the release of histamine from rat peritoneal mast cells (RPMCs) was suppressed significantly. These results suggest that the inhibitory effect of RJWE on AD might be associated with mast cells.

  • The behavioral phenotypes of out-bred ICR mice were compared with those of in-bred C57BL/6 and BALB/c mice. In particular, this study examined the locomotor activity and two forms of hippocampus-dependent learning paradigms, passive avoidance and object recognition memory. The basal open-field activity of the ICR strain was greater than that of the C57BL/6 and BALB/c strains. In the passive avoidance task, all the mice showed a significant increase in the cross-over latency when tested 24 hours after training. The strength of memory retention in the ICR mice was relatively weak and measurable, as indicated by the shorter cross-over latency than the C57BL/6 and BALB/c mice. In the object recognition memory test, all strains had a significant preference for the novel object during testing. The index for the preference of a novel object was lower for the ICR and BALB/c mice. Nevertheless, the variance and the standard deviation in these strains were comparable. Overall, these results confirm the strain differences on locomotor activity and hippocampus-dependent learning and memory in mice.

  • Objectives : This study was carried out to know the effect of Cordyceps sinensis(CS) on the immune inflammatory responses of spleen cells and function or immunocytes of the normal mouse. Methodes: We investigated effects of Cordyceps sinensis(CS) on normal immunocytes, gene expression of IL-12, IFN-$\gamma$ and surface-receptor expression of $CD3_{\epsilon}+$, CD4+, CD8+ and CD19+ cells were measured by PCR and FACS. Results : CS activated adhisive splenic cells morphologically as compared with the control group in the normal spleen cells of BALB/C mice. CS enhanced gene expression of interleukin-12 and interferon-gamma in a dose-dependent manner in the normal spleen cells of BALB/C mice. CS reduced the number of activating cells and surface-receptor expression of CD4+, CD8+ and CD19+. Conclusion : Cordyceps sinensis will be used as a stable remedium in the auto-immune diseases.

  • Avian infectious bronchitis virus(IBV) was propagated in SPF eggs and purified by sucrose density gradient centrifugation in order to prepare the antigen. Several fusions were made between mouse myeloma cells and spleen cells from BALB/c mouse immunized with IBV antigen and two hybridoma clones producing specific monoclonal antibody(MCA) against the IBV were established. The MCAs were classified as IgG type and revealed no neutralizing and hemagglutination inhibition activity. Using the MCA IBV antigen was detected by IFA method in tracheal smears made from chickens infected with IBV during the experimental period of 10 days.

  • Antitumor activities of a peptide fraction isolated from traditional Korean soy sauce (SSP) were investigated in vitro and in vivo using cancer cell lines and F9 teratocarcinoma-bearing BALB/c mice. SSP exerted a dose-dependent antiproliferative effect on P388D1 mouse lymphoma, F9 mouse teratocarcinoma, and DLD-l human colon cancer cells with $IC_{50}$ values of 11, 50, and $50\mug/ml$, respectively. Tumor growth in F9 teratocarcinoma-bearing BALB/c mice, orally administered with 80 and 200 mg/kg/day of SSPs, was inhibited 10.3% and 52.4%, respectively, and survival days increased by 11.9% and 22.1%, respectively, compared to the control group. The results of antitumor activities exerted by SSP in vitro and in vivo suggest the feasibility of using SSP as an antitumor agent.

  • The purpose of this research was to investigate the effect of reaction-precipitate from Coptidis Rhizoma and Glycyrrhizae Radix aqueous mixture(CGP) on the cytotoxicity. The effects of CGP on the growth of tumor cells, Balb/c 3T3 cell, mouse spleen cell and human lymphocyte were compared with those of berberine, glycyrrhizin and berberine glycyrrhizinate(BG), which were estimated by MTT colorimetric assay or cell counting. CGP, berberine and BG inhibited the growth of several tumor cells, such as Hep G2, A549, Raji, MCF-7, HeLa and KHOS-NP. Whereas, glycyrrhizin inhibited the growth of Raji and MCF-7, CGP did not affect on Balb/C 3T3 cells, mouse spleen cells and human lymphocyte at $10^{-6}{\sim}10^{-5}g/ml$. CGP increased the number of leukocyte in mice. This results indicate that CGP have the inhibitory action of the growth of human tumor cells, and the side effect of CGP is less than berberine and BG.

  • The therapeutic effectiveness of adenine arabinoside(tora-A) and its conjugate of prednisone(BR-8702-AP) was compared in Herpes simplex Virus Type 1 (HSV-1) infected BALB/C mice. The BALB/C mouse was infected with HSV-1(700 PFU/mouse) intranasally. Among mice infected intranasally with virus, a mortality rate of 100% was observed. On the oral administration of non-toxic doses of ara-A or BR-8702-AP(125 mg /kg/day) for 5 consecutive days 2 hours after virus infection, the tora-A was highly effective in reducing mortality to 0% (P<0.001) and BR-8702-AP was also effective in reducing mortality to 15% (P<0.01). In this model infection, the virus was first replicated in the lung and transmitted to the brain. Both arts-A and BR-8702-AP did not inhibit the viral replication in the lung, but they inhibited the viral transmission to the brain. However, the BR-8702-AP was less effective than the aria-A to prevent transmission of virus to brain. Therefore, the reduced mortality due to tora-A or BR-8702-AP therapy was associated with inhibition of viral transmission to brain.
