  • Bujeonghangamtang(扶正抗癌湯) has been used for cure of tumor as a traditional medicine without any experimental evidence to support the rational basis for its clinical use. This study was carroed out to evaluate the possible therapeutic or antitumoral effects of Bujeonghangamtang extract against tumor, and to carry out some mechanisms responsible for its effect. Some kinds of tumor were induced by .the typical application of 3-methylcholanthrene (MCA) or by the implantation(s.c) of malignant tumor cells such as leukemia cells(3LL cells) or sarcoma cells(Sl80 cells). Treatment of the Bujeonghangamtang water-extract (dailly 1mg/mouse, i. p.) was continued for 7 days prior to tumor induction and after that the treatment was lasted for 20 days. Against squamous cell carcinoma induced by MCA, Bujeonghangamtang decreased not only the frequency of tumor production but also the number and the weight of tumors per tumor bearing mice (TBM). Bujeongmngamtang also significantly suppressed the development of 3LL cell and S180 cell-implanted tumors in occurence-frequency and their size, and some developed tumors were regressed by the continuous treatment of Bujeonghangamtang extract into TBM. In vitro, treatment of Bujeonghangamtang extract had no effect on the growth of some kinds of cell line such as FsaII, A431 strain but significantly inhibited the proliferation of 3LL, S180 cells and augmented the DNA synthesis of mitogen-activated lymphocytes. Bujeonghangamtang also stimulated the migrative ability of leukocyte, the MIF and IL-2 production of T lymphocytes, but not IL 6 production of B cells. Bujeonghangamtang-administration to mice enhanced NK cells attivities. These results demonstrated that Bujeonghangamtang extract exhibited a significant prophylactic benefits against tumors and its antitumor activity was manifested depending on the type of tumor cells. And these results also suggested that effect of Bujeonghangamtang might be chiefly due to nonspecific enhancement of NK cell activities and cell-mediated immune responses.

  • This study was undertaken to assess the effect of ginseng administration on T lymphocyte induced local xenogenic graft-versus-host(GVM) reactions which were induced with thymocyte, spleen cell and lymph node cell of ICR mice. Mice received daily 10mg of 70% alcohol ginseng extract oral1y for 100days and control mice remained untreated for the same period of time. The cells from donor mice were injected intradermally into the closely shaven abdominal skin of Sprague-Dawley rats for GVH tests. The thymocyte from control(ginseng-untreated) mice showed a negative local GVH reaction, whereas thymocyte from experimental(ginseng-treated) mice showed a positive reaction with the rate of 17.4%. When spleen cells were injected, the incidence of positive local GVH reaction was 66.7% among ginseng-treated mice, as opposed to incidence of 45.5% of positive local GVH reaction among control mice. The incidence of positive local GVH reaction of the lymph node cells when injected into a recipient was 71.4% among ginseng-treated mice as compared with that of 18.9% among control mice. The relationship between spleen cell inoculum and intensity of the local GVH reaction was assessed in ginseng-untreated mice. The intensity of GVH reaction clearly appears to be dose related. In ginseng-treated mice, a minimum of $1{\times}10^7$ spleen cell was required for production of positive local GVH reaction with almost linear relationship up to an inoculum of $5{\times}10^8$ cells. In control mice, however, a minimum of $1{\times}10^8$ spleen cells was required for positive GVH reaction. These results strongly suggest that the ginseng administration augments significantly the local xenogenic GVH reaction which was used to assess T lymphocyte function and immunocompetence of mice and in addition to this, these results appear to support previous suggestions that the local GVH reaction consitutes a qualitative test of the functional activity of T lymphocytes. These results may be the first to induce local GVH reaction, employing rats as recipient and mice as donor. This study was also desingned to investigate some of the effects of ginseng extract on lymphocyte-macrophage interactions. This was accomplished by in vitro quantification of 1) migratory inhibitory factor(MIF) synthetic capacity of splenic lymphocytes in mice previously primed with ginseng 2) MIF responsiveness of mouse peritoneal macrophages or chicken peripheral leucocytes under the presence of ginseng extract 3) migration ability of chicken peripheral leucocytes by direct stimulation of ginseng extract or ginseng saponin and 4) immunosuppressive effects of immunosuppressants such as cyclophosphamide, cyclosporin A or dexamethasone. Mice divided equally into the ginseng and the saline groups, which received intraperitoneally daily 0.2ml of ginseng absolute alcohol-extract(5mg/ml) and same amount of saline for 15 days, respectively. The cellular immune responsiveness of these mice was assayed 15 days after ginseng pretreatment. Splenic lymphocytes of mice treated with ginseng, when stimulated with sensitized specific-antigen such as sheep red blood cells or toxoplasmin, or with polyclonal activator concanavalin A, produced significantly more MIF than those of control saline group. MIF responsiveness of normal mouse macrophages was significantly augmented when assayed under the presence of ginseng extract (1mg/ml). The migratory ability of normal chicken leucocytes in the absence of MIF was significantly decreased by the stimulation of ginseng extract alone. MIF response was significantly decreased by immunosuppressants and this impaired response was not restored by ginseng pretreatment. This study was additionally performed to evaluate the effect of ginseng on the expulsion of adult Trichinella spiralis in mice. ICR mice were infected experimentally by esophageal incubation of 300 T. spiralis infective muscle larvae prepared by acid-pepsin digestion of infected mice. and received oral administration of 70% alcohol ginseng extract(10mg/mouse/day) for the indicated days plus 4 days before infection. At various times after infection, the number of adult T. spiralis worms in small intestines was determined. Interestingly, ginseng-treatment was accompanied by accelerated expulson of T. spiralis. These results led to the conclusion that Panax ginseng caused some enhancing effect on GVH reaction, macrophage migration inhibition reaction and expulsion of T. spiralis. In addition these results suggested that the mechanisms responsible for this enhancement of ginseng may be chiefly or partially due to nonspecific stimulation of cell-mediated immune response.

  • 복합 생약재 열수추출물(6종 혼합)을 농도별 기간별로 사료에 흡습시켜 12주 동안 넙치에 급여 후 비특이적 면역 및 질병저항성에 대한 효과를 조사하였다. 복합 생약재 열수추출물의 첨가는 어류 성장에는 아무런 영향을 미치지 않았으며 혈액생화학적인, 결과도 넙치의 생리에는 아무런 영향을 미치지 않았다. 라이소자임 활성은 0.01%의 복합 생약재 열수추출물 농도로 흡습시킨 사료 그룹에서 라이소자임 활성이 증가됨을 알 수 있었다. 복합 생약재 열수추출물의 투여에 따른 넙치 장기의 병리조직에 영향이 없음을 알 수 있었다. 에드와드균의 인위감염에 의한 질병저항성은 0.01% 복합 생약재 열수추출물 농도에서 상대생존율이 높게 나타났다. 이상의 결과를 종합하여 볼 때 넙치에 복합 생약재 열수추출물을 투여시에는 어류의 비특이적 면역력 증강 및 질병 저항성 증강을 나타내는 것으로 사료되었다.

  • 비브리오 패혈증의 원인균인 V vulnificus에 대한 어류의 저항성을 증강시키기 위한 연구로써, 비브리오 백신이 경구로 투여된 넙치에서의 특이 또는 비특이적 면역반응을 조사하였다. 넙치에 대하여 UHKB (uncoated heat killed bacterin of V. vulnincus)를 20rng1kg b.w.의 농도로 경구를 통하여 4주 연속 투여 (4W) 또는 1주 동안 투여하고 2주 동안 투여하지 않다가 다시 1주 동안 투여 (1-2-lW) 하는 두 가지 방법으로 실시한 후 형성된 혈청내 특이 항체량을 비교한 결과 1-2-1W group은 4W group에는 도달하지 못하였지만 명백히 증가된 특이 항체량을 보여주었다. UHKB를 1주일에 2회씩 4주 연속 투여한 실험구가 최종 투여 후 2주 째부터 가장 높은 항체가를 보여 주었고 이러한 경향은 전 실험기간 동안 계속 유지되었다. 이러한 실험 결과는 단일세포수준에서 분석된 특이항체 생성세포 (SASC) 수의 계측에서도 확인되었는데 백신의 최종 경구투석 후 1주 째부터 대조구에 비하여 증가를 보인 실험구의 SASC수는 최종 투여 후 8주 째까지 유지되었다. 그러나 내산성으로 제조된 백신 (ECHB)은 V.vulnificus에 대한 항체생성 면역반응 그리고 인위 감염시킨 V vulnifcus (1$\times$10 CFU/kg b.w.) 생균의 체내 제거능력 분석 양쪽 모두에서 UHKB에 비하여 낮은 결과를 보여 주었다. 그러므로 넙치에 경구 투여된 UHKB는 V vulnificus의 오염을 억제 할 수 있는 효과적인 방법으로 확인되었으나 내산성으로 제조된 ECHB는 면역반응 증가를 유도하지 못하는 것으로 나타났다.
