  • 동물세포에 미치는 웅담의 영향을 조사하기 위해서 원숭이 kidney cell 유래의 COS-7 cell과 hybridoma cell(murine myeloma cell과 rat의 spleen cell을 융합)을 가지고 이들 세포의 생육과 단백질 발현기작에 미치는 영향을 조사했다. COS-7 cell과 hybridoma cell을 웅담이 첨가된 10% FCS DMEM complete medium에서 78시간 배양한 결과 COS-7 cell에는 거의 영향을 미치지 않았으나 myeloma cell과 spleen cell과의 융합세포는 48시간내에 거의 모든 세포가 사멸됐다. 또한 cDNA를 COS-7 cell에 transfection에서 발현되는 단백질양을 조사한바 웅담이 첨가된 배지에서의 단백질 생산량이 첨가되지 않은 배지에서 보다 $30{\sim}40%$ 감소되었다.

  • This study was carried out to determine effectively the sex of rabbit embryos using H-Y antiserum. H-Y antiserum was obtained from inbred SD strain female rat which was immunized by injection of testis cell of inbred SD strain male rate into its spleen. The titer of antiserum was identified by sperm cytotoxicity test and culture of rabbit embryos with antiserum. The developed or undeveloped embryos were separated by exposure the embryos to the antiserum with H-Y antibody. Developed embryo were transferred to the recipients and sex of offspring were examined. 1. In the sperm cytotoxicity test, the rate of dead sperm showed no difference between two antisera from spleen and testis cell as antigens. It is confirmed that H-Y antibody in antiserum was absorbed by H-Y antigen in male rat spleen cells. 2. When rabbit morulae were exposed to antiserum and complement, the rate of embryos developed or arrested was 51 and 49% respectively and the rate was closely same as natural sex ratio of 50:50%. 3. When rabbit morulae were cultured for 12h in the medium containing antiserum produced by antigen of testis cell, the rate of embryos developed or arrested was 48 and 52% respectively and the rate was closely same as natural sex ratio of 50:50%. 4. Eighty rabbit embryos which were not affected by H-Y antiserum were transferred to four recipients. Two recipients were pregnant and born 13 pups among which 2 (14%) were male and 11 (86%) were female. In conclusion, existence of H-Y antibody in the serum from female rat immunized by injecting testis cell from newborn male rat to the spleen of the female rat was confirmed. When rabbitmorulae were exposed to H-Y antiserum and complement, about a half of embryos were developed to blastocysts. When the rabbit embryos not affected by H-Y antiserum were transferred, the rate of female offspring was 86%. Therefore, it was identified that most of embryos which were not affected by H-Y antiserum were female.

  • These expriments were carried out to investigate existence of H-Y antibody in the rat serum immunized against H-Y antigen from rat spleen cells and effect of H-Y antiserum on development of mouse male embryos. The results obtained were summerized as follows : 1. When mouse embryos were cultured for 48∼72 hrs in the Ham's F10 containing 16% of FBS(fetal bovine serum) or RNS(rat normal serum), percentages of embryos developed from 2, 4, 8 and 16-cell embryo to morulae were 20, 27, 94 and 100%, respectively, in FBS and 8, 7, 94 and 100%, respectively, in RNS. Eight to 16-cell embryos showed no difference in development rate between FBS adn RNS. 2. When 8∼16-cell mouse embryos were cultured for 24∼48 hrs in the Ham's F10 containing FBS, RNS+GPC(guinea pig complement) and RAS(rat antiserum)+GPC, proportions of embryos developed to the expanded blastocyst stage were 100, 82.4 and 52.1∼53.6%(ave.52.9), respectively, so that it was suggested that rat antiserum suppressed development of male embryos. 3. When 8∼16-cell mouse embryos were cultured for 24∼48 hrs in the Ham's F10 containing FBS, RNS, RNS+GPC and RAS+GPC, proportions of embryos developed to the expanded blastocyst stage were 94.5, 90.9, 82.3 and 47%, respectively, and the embryos developed in the medium containing RAS+GPC seemed to be female. These results indicated that the antisera prepared through immunized against H-Y antigen from rat spleen cell, possessed H-Y antibody which supressed development of male embryos.

  • In order to investigate the immunostimulating effect of mycelia extract of Phellinus linteus (PLM) on human monocyte THP-1 and rat peritoneal macrophage cell, we examined measuring cytokine secretion (IL-6 and TNF-${\alpha}$). The production of IL-6 and TNF-a in human monocyte THP-1 was slight increased dose-dependently when the cells were challenged with PLM for 72 hrs. It was also observed that the treatment of PLM with LPS augmented the production of IL-6 and TNF-a in human monocyte THP-1. It was also observed that the treatment of PLM with LPS augmented the production of IL-6 and TNF-${\alpha}$ in human monocyte THP-1. The production of IL-6 and TNF-${\alpha}$ in rat peritoneal macrophage was significantly enhanced when the cells were treated PLM with LPS for 72 hrs. Moreover, the proliferation rate of rat spleen cells was increased in a dose dependent manner as the cells were treated with PLM and Concanavalin A.

  • Objectives : To investigate the effects of herb-acupunctures of Qi tonification herbs or formula on the rat immune depression induced by an anticancer drug, methotrexate (MTX) Methods: Animals were divided into 5 groups; Normal control group was not given any treatment. Immune depression was induced by oral administration of 1mg/kg MTX b.i.d for 4 days in Control, Sample I, II, and III groups. We treated on CV 4 (Guanyuan) with saline, Bojoongiggi-tang (Buzhongyiqi-tang), Ginseng Radix and Astragali Radix herb-acupunctures in Control, Sample I, II, and Ill groups, respectively. In both blood and spleen, the assessment of CD4+ T-cell count, CD8+ T-cell count, CD4/CD8 T-cell ratio was performed. Results: Here we show that 3 herb- acupuncture groups have an influence, to some extent, on CD4+ and CD8+ T-cell counts and CD4/CD8 T-cell ratio in both blood and spleen. Astragali Radix herb-acupuncture, in particular, was found to have significantly increased CD4+ T-cell count in blood and CD4/CD8 T-cell ratio in blood and spleen. Conclusions: The results of this study suggest that herb-acupunctures of Bojoongiggi-tang (Buzhongyiqi-tang), Ginseng Radix and Astragali Radix may have an influence over rat immune depression induced by MTX.

  • These experiments were carried out to clarify the optimalconditions and interspecific cross reaction of H-Y antibody activity. H-Y antiserum was prepared in inbred SD female rats and Balb/c female mice by repeated immunization of rat newborn testis homogemate, rat and mouse spleen cells obtained from males of same strain. The activity of H-Y antibody in antiserum was tested by ELISA and biological tests. The cross reactivity of H-Y antibody was confirmed by culturing mouse and rabbit embryos in medium containing H-Y antibody and complement obtained from rat and guinea pig, respectively. The optimal condition for the activity of H-Y antibody was also investigated by culturing embryos in medium with different pH and complement concentration. The results obtained in these experiments were summarized as follows: 1. The formation rates of H-Y antibody in rats immunized with newborn testis and spleen cell were 40.0 and 50.0% respectively, and that in mouse immunized with spleen cell was 48.4%. 2. The activity of H-Y antibody was not affected by pH in range of 6.5 to 8.0, and the same was true for the relative concentration of complement to the H-Y antibody. 3. Minimum time needed for the activity of H-Y antibody was confirmed to be 0.5 to 1 hour and 24 to 48 hours respectively for the zona free embryos and intact embryos. 4. When mouse and rabbit embryos were treated with H-Y antibody obtained from rat, 46.4 and 54.8% of embryos were retarded or destroyed. From these results it could be said that H-Y antibody had strong interspecific cross reactivity.

  • Natural Killer cells are considerd to play an important role in antitumor immune surveilance mechanism. In this study, 21 putative anticancer drugs selected from reference were assessed by evaluating the effect on rat Natural Killer cell activity (NKCA). All 21 herb drugs were extracted in boiling water, lyophilized, autoclaved, and then used for experiment. Culture supernatant of concanavalin-A (Con-A)-stimulated rat spleen cells as a source of lymphokine was also used as a control of comparison. Rat spleen cells were used as effector and NKCA was measured in 4hr $^{51}Cr-release$ assay against Yac-1 mouse lymphoma cell line. In order to determine the optimal conditions for NKCA augmentation, effector cells were treated with 3 different concentrations of each drug for 24, or 48 hrs before testing of NKCA, In optimal conditions determined from previous results, the effect of herb drugs on NKCA were assessed in 3 to 5experiments. NKCA was significantly enhanced by treatment with 4 herb drugs(Ponciri Fructus, Houttuyniae Herba, Aurantii Pericarpium, Nepetae Herba). Culture supernatant of Con-A-stimulated spleen cells also augmented the rat NKCA more significantly. The results show that 4 of the herb medicines supposed to display anticancer effect may have activity as a biological response modifier through augmentation of NKCA.

  • Leptin is a circulating non-glycosylated protein that is mainly produced in adipocytes. Leptin acts in the brain to regulate food intake and energy expenditure. Previously we reported our success in the isolation of a partial cDNA of the long form of the leptin receptor, OB-Rb, from rat spleen, and showed that leptin might also play a role in peripheral immune organs. In the present study, for the first time, the complete coding region of OB-Rb cDNA was cloned from rat splenocytes, and its nucleotide sequence was determined. The cDNA was then further expressed in E. coli and mammalian cells, thereby confirming the functional integrity of this receptor. Prokaryotically overexpressed OB-R protein was then used as an immunizing antigen in BALE/c mice to produce leptin receptor-specific antibodies. By using them, we confirmed the cell surface expression of OB-Rb in transfected CHO cells. It is our belief that the reagents, as produced in this study, will be of great use in further studies of the biological role of rat leptin.
