Fowl typhoid caused by Salmonella gallinarum has increased dramatically since 1992 and has caused a great economic losses in chicken industry by characterizing with high mortality. In these studies, we investigated the immunogenicity and protectivity in chickens which were immunized with outer membrane protein(OMP) extracted from isolates of S gallinarum against challenge with live microorganism. Outer membrane proteins were composed of various sizes of molecular weight including 14K, 22K, 31K, 36K, 40K and 55K and the most of them responded strongly against rabbit antisera in immunoblot analysis. The chickens vaccinated with OMP or vaccinated with whole-cell combined with OMP($200{\mu}g$/chickens) complex showed higher delayed type hypersensitivity(DTH) response than that of whole-cell vaccinated group. The protective rates of OMP or whole-cell combined with OMP complex group against challenge of S gallinarum were higher (above 75%) than those (45~50%) of whole-cell vaccinated group. All vaccines were safe and the body weight-gains of all vaccinated groups were not significantly different (p<0.05) from those of nonvaccinated control group. In vitro tests, OMP stimulated both the proliferation of lymphocytes and T-lymphocytes, and OMP-induced lymphocyte proliferation was higher in the cells of the immunized chickens with OMP than in those from the control chickens.

To know the effects of Gentiana macrophylla(GM) on the immune response, this study was undertaken. GM is one of the well-known oriental medicines for a lomg time used for the treatment of such diseases as arthralgia, headache, hepatitis, SLE, hemiparesis, and so on. To evaluate the effects of GM on immune response in the collagen induced arthritis, phagocytic activity of macrophages, proliferation of T-lymphocytes, secretion of nitric oxide in urine, and production of ROIs, $TNF-{\alpha}$ and nitric oxide in synoviocytes were measured. The results obtained in this study were as follows: 1. During the progress of CIA, the administration of GM enhanced phagocytic activity of macrophages in vivo and vitro. 2. During the progress of CIA, the administration of GM inhibited production of ROIs in synoviocytes. 3. During the progress of CIA, the administration of GM inhibited production of TNF- a in synoviocytes. 4. During the progress of CIA, the administration of GM inhibited proliferation of T lymphocytes. 5. During the progress of CIA, the administration of GM inhibited production of nitric oxide in synoviocytes. 6. During the progress of CIA, the administration of GM inhibited secretion of nitric oxide in urine. According to the above results, during the progress of CIA, it might be considered that GM has a curative effect on rheumatoid arthritis by controling immune response.

Astragalus membranaceus Bunge (黃?), Atractylodes macrocephala Loidz (白朮), Angelica sinensis(Oliv) Kiels (當歸), Lycium chinense Mill (枸杞子), Ligustrum lucidum Ail (女貞子) are Herbs that are frequently used in a lot of prescriptions to reduce the side effects of anti-cancer therapies, especially like chemotherapy and radiotherapy. The radioprotective and hemopoietic effects of these Herbs on BALB/c splenocytes and bone marrow cells are measured. In order to evaluate the Hemopoietic effects, Thymidine uptakes and secretion of colony stimulating factors(CSFs) of splenocytes and myelocytes treated with herbs were measured. Radioprotective effects were accessed by the method of immunocompetence of murine lymphocytes cultured with herbs before irradiation and with LPS, ConA after irradiation. The results are as follows. 1. The orders of Proliferative effects of herbs on splenocytes were Atractylodes macrocephala Loidz (白朮), the higest of all, Astragalus membranaceus Bunge (黃?), Angelica sinensis(Oliv) Kiels (當歸). Lycium chinense Mill (枸杞子) and Ligustrum lucidum Ait (女貞子), the lowest of all. At Optimal concentration, the proliferation ratios of herb-treated splenocytes compared to non-treated ones were like these. Atractylodes macrocephala Loidz (白朮) 44.3, Astragalus membranaceus Bunge (黃?) 17.7, Angelica sinensis(Oliv) Kiels (當歸) 10, Lycium chinense Mill (枸杞子) 6.4, Ligustrum lucidum Ait (女貞子) 2.0.(p<0.05) 2. When splenocytes were cultured during different periods, Atractylodes. macrocephala Loidz (白朮) and Astragalus membranaceus Bunge (黃?) showed the higest proliferation on 3th day, Angelica sinensis(Oliv) Kiels (當歸), Lycium chinense Mill (枸杞子) on 4th day,(p<0.05) and Ligustrum lucidum Ait (女貞子) until 5th day but with no significant increase. 3. The orders of Proliferative effects of herbs on Bone Marrow(BM) cells were Atractylodes macrocephala Loidz (白朮), the higest of all, Astragalus memhranaceus Bunge (黃?), Angelica sinensis(Oliv) Kiels (當歸), Lycium chinense Mill (枸杞子) and Ligustrum lucidum Ait (女貞子), the lowest of all too. At Optimal concentration, the proliferation ratios of herb-treated BM cells compared to non-treated ones were like these. Atractylodes macrocephala Loidz (白朮) 21.7, Astragalus membranaceus Bunge (黃?) 9.9, Angelica sinensis(Oliv) Kiels (當歸) 4.9, Lycium chinense Mill (枸杞子) 2.3, Ligustrum lucidum Ait (女貞子) 1.4(p<0.05). 4. The secretion ratio of colony stimulating factors(CSFs) of each herb-treated group, compared to control, was Atractylodes macrocephala Loidz (白朮) 9.4, Astragalus membranaceus Bunge (黃?) 9.0, Angelica sinensis(Oliv) Kiels (當歸) 4.4, Lycium chinense Mill (枸杞子) 3.8 (p<0.05) but no significant increase in Ligustrum lucidum Ait (女貞子). 5. The mitogen(ConA, LPS) stimulated-lymphocytes cultured with each herb before irradiation of 1-3 Gy showed more enhanced proliferation than control(p<0.05). When compared to each non-irradiated group of all groups, the orders of percentage increase of irradiated group were Atractylodes macrocephala Loidz (白朮), the higest of all, Astragalus membranaceus Bunge (黃?), Angelica sinensis(Oliv) Kiels (當歸), Ligustrum lucidum Ait (女貞子), Lycium chinense Mill (枸杞子). Each percentage showed significant enhancement compared to control group(p<0.05). According to the results, Atractylcdes macrocephala Loidz (白朮), Astragalus membranaceus Bunge (黃?) are suggested to be the most effective hemopoietic and radioprotective herbs, and Angelica sinensis(Oliv) Kiels (當歸), Lycium chinense Mill (枸杞子) the next, but Ligustrum lucidum Ait (女貞子) showed lower effects than expected.

The studies were conducted to investigate the combined effects of several combined preparation of crude drugs and mitomycin C(MMC). The combined effects on the proliferation of Molt-4 cells and activation of human lymphocytes were estimated by MTT colorimetric assays. The drugs itself enhanced the proliferation of Molt-4, but the inhibitory action of MMC was not affected by the combined treatment of the drugs and MMC. Among 9 kinds of the drugs, Sip Jeon Dae Bo Tang(SDT), Saeng Maek San(SMS) and Kwi Bi Tang(KBT) did not inhibit the action of MMC, but activated lymphocytes. When the mice were treated by MMC, the number of leukocytes was decreased significantly at the 1st day, but recovered at the 7th day. In the groups of MMC treated with SDT or KBT, the number of leukocytes was increased significantly than the group of MMC treated only at the 3rd day. The combined treatment of SDT, SMS and MMC retained the body weight of mice at the level of normal mice. The SDT, SMS and KBT did not change the number of plaque forming cells(PFC) and the proliferation of T cells. The combined treatment of SDT and MMC increased the number of PFC significantly than the MMC treated group. The combined treatment of SDT, SMS, KBT and MMC increased the T cell proliferation significantly than the MMC treated group. In conclusion, it is suggested that SDT, SMS and KBT can recover the side effects of MMC, such as weight loss, leukopenia and immunosuppression, without any intercalating the anti-proliferative action of MMC in vivo.

The maintenance of a viable pregnancy has long been viewed as an immunological paradox. The deveolping embryo and trophoblast are immunologically foreign to the maternal immune system due to their maternally inherited genes products and tissue-specific differentiation antigens (Hill & Anderson, 1988). Therefore, speculation has arisen that spontaneous abortion may be caused by impaired maternal immune tolerance to the semiallogenic conceptus (Hill, 1990). Loss of recall antigen has been reported in immunosuppressed transplant recipients and is associated with graft survival (Muluk et al., 1991; Schulik et al., 1994). Progesterone $(10^{-5}M)$ has immunosuppressive capabilities (Szekeres-Bartho et al., 1985). Previous study showed that fertile women, but not women with unexplained recurrent abortion (URA), lose their immune response to recall antigens when pregnant (Bermas & Hill, 1997). Therefore, we hypothesized that immunosuppressive doses of progesterone may affect proliferative response of lymphocytes to trophoblast antigen and alloantigen. Proliferative responses using $^3H$-thymidine ($^3H$-TdR) incorporation of peripheral blood mononuclear cells (PBMCs) to the irradiated allogeneic periperal blood mononuclear cells as alloantigen, trophoblast extract and Flu as recall antigen, and PHA as mitogen were serially checked in 9 women who had experienced unexplained recurrent miscarriage. Progesterone vaginal suppositories (100mg b.i.d; Utrogestan, Organon) beginning 3 days after ovulation were given to 9 women with unexplained RSA who had prior evidence of Th1 immunity to trophoblast. We checked proliferation responses to conception cycle before and after progesterone supplementation once a week through the first 7 weeks of pregnancy. All patients of alloantigen and PHA had a positive proliferation response that occmed in the baseline phase. But 4 out of 9 patients (44.4%) of trophoblast antigen and Flu antigen had a positive proliferative response. The suppression of proliferation response to each antigen were started after proliferative phase and during pregnancy cycles. Our data demonstrated that since in vivo progesterone treated PBMCs suppressed more T-lymphocyte activation and $^3H$-TdR incorporation compare to PBMCs, which are not influenced by progesterone. This data suggested that it might be influenced by immunosuppressive effect of progesterone. In conclusion, progesterone may play an important immunological role in regulating local immune response in the fetal-placental unit. Furthermore, in the 9 women given progesterone during a conception cycle, Only two (22%) repeat pregnancy losses occured in these 9 women despite loss of antigen responsiveness (one chemical pregnancy loss and one loss at 8 weeks of growth which was karyotyped as a Trisomy 4). These finding suggested that pregnancy loss due to fetal aneuploidy is not associated with immunological phenomena.

알코올 중독자의 폐렴관리와 같은 건강관리에 필요한 비특이 면역력, 면역기능을 측정하기 위하여 알코올 중독 의존형으로 입원한 신,구환자군에 대하여 다음과 같은 결과를 얻었다. 대조군에 대한 알코올 중독증은 MCV, 혈당, $\gamma$GTP를 이용한 생물학적 측정 결과에 의하여 확인하였으며, 기타 측정 항목은 대조군과 유사한 결과를 나타내었다. 림프구 아형 분석 결과 대조군은 한국인 참고치와 매우 유사하였으며, 실험군 CD4+를 제외한 CD3+, CD8+, CD19+이 감소되었고, CD4+/CD8+비율은 통계적으로 유의하게 증가되어 있음을 알 수 있었다. 따라서 실험군의 면역기능과 림프구 증식능은 대조군에 비하여 현저하게 저하되었으며, 탐식세포 탐식능 및 유주능도 대조군에 비하여 현저하게 감소되었다. 탐식세포의 유주능과 CD4+의 증가, CD4+/CD8+비율의 증가와 PHA에 의한 림프구 증식능의 감소 및 CD3+, CD19+ 감소등은 상호관련성을 가지고 일치된 결과를 보여 대조군에 비하여 현저하게 저하된 탐식세포의 탐식기능과 함께 알코올 중독자의 비특이 면역계, 면역기능이 현저하게 저하되어 있음을 알 수 있었다. 그러나 알코올 중독 의존형으로 입원한 신,구환자간의 비교 분석 결과 총단백질, 혈색소, 림프구 증식능, 탐식세포 탐식능, 유주능에서 신환자군에 비하여 구환자군이 대조군에 다소 근접되어가는 결과로부터 치료에 따라 숙주의 세포성, 체액성 면역기능이 회복되어가고 있음을 알 수 있었다. 또한 결과 알코올중독자의 비특이적 면역능의 측정을 위한 탐식세포 탐식능, 유주능은 숙주, 미생물측의 활성화 자극인자가 모두 포함된 phagocytic plaque film법에 의하여 측정함이 의의 있는 평가를 할 수 있을 것으로 보며, CD4+/CD8+ 림프구 아형 비율을 이용한 면역기능의 측정은 알코올 중독자의 건강 관리를 위한 면역력 측정에 유용한 방법이라고 생각된다사이에서는 차이를 인정할 수 없었다. 그러나 25개월 운동군은 대조군에 비하여 유의한 차이로 감소하였다. 연령증가에 따른 사립체 내막 표면밀도와 사립체수는 대조군과 운동군 사이에는 유의한 변화는 없었다. 본 연구의 성적을 검토한 결과 젊은층(3개월군)과 중령층(10개월군)의 횐 쥐에서는 반복된 지구력운동이 심장에 미치는 역효과를 인정할 수 없었으며 젊은 층의 횐 쥐에서는 오히려 심장기능 강화를 보이는 경향이 나타났으며, 노화층(20개월군)에서 운동군에서는 스트레스로 작용하여 심장기능의 저하를 초래하였다고 생각된다.서 낭송된다. 그러나 이 연구의 기본은 시인과 독자의 율형(Metrical Pattern)에 대한 의식과 의도(intention)가 전제된다. 이것은 이 연구의 문제임과 동시에 장점이다. 시율의 분석은 보는 율형이 아니라 읽고 낭송하는 율형으로 분석되어야 함을 보여 준 것이 이 연구의 기여이다.ight reduction but the rapid weight gain was noticed right after the diets ceased.나 인과 질소 평형에는 큰 영향을 미치지 않았다.더덕은 20(種)이었다. 9.

Infectious mononucleosis(IM) Is an acute self-limiting lymphoproliferative disorder associated with infection by the Epstein-Barr Virus(EBV), with the characteristic triad of fever, sore throat, and cervical or generalized lymphadenopathy. And also there are atypical lymphocytes in the peripheral blood. Cytological findings of IM lymphadenitis are characterized by a florid immunoblastic and atypical lymphoid cell proliferation. However, the small number of cases were studied by fineneedle aspiration cytology(FNAC) even though there was a complexity of lymph node pathology. It is important to recognize the reactive pattern of IM that would initiate EBV study and to avoid unnecessary biopsy We studied findings of lymph node FNAC from 4 patients with EBV infection confirmed by EBV-specific serologic studios. All of the cases were positive for viral capsid antigen(VCA) and one case was positive for anti-EBV nuclear antigen(EBNA). Cytologically, all of the cases exhibited high cellularity and atypia with great numbers of large immunoblastic lymphocytes.

The purpose of this research was to investigate the immuno-modulatory effect and anti-carcinogenic property of Cordyceps militaris(CM) and/or Paecilomyces japonicus (PJ). The proliferation of cultured splenocytes and thymocytes were enhanced by the addition of 10 ㎍/ml of CM and/or PJ. B lymphocytes subpopulation in splenocytes were increased both CM and/or PJ administered(p.o. for 7 days)-mice. Thymic T lymphocytes, especially TH cells were significantly increased in CM-administered mice. CM and/or PJ treatment inhibited the cell viability of L 1210 mouse leukemia and HL60 human leukemia cells and induced the apoptosis of L1210 and HL60 cells. In addition, CM and/or PJ increased the hemaggutination(HA) titer against SRBC. These results suggest that CM and/or PJ have an immuno-modulatory action and anti-carcinogenic property.

Bordetella (B.) bronchiseptica is a causative agent of swine atrophic rhinitis that promotes colonization of the mucous membrane of the swine nasal cavity by Pasteurella (P.) multocida. Mixed infection with B. bronchiseptica and P. multocida leads to growth inhibition of pigs, resulting in significant economic loss. There are many commercial vaccines for atrophic rhinitis, including B. bronchiseptica as a killed vaccine antigen (Ag). However, the immunogenicity of killed B. bronchiseptica Ag has not yet been elucidated; therefore, this study was conducted to investigate the immunogenicity of killed B. bronchiseptica Ag and the type of immune response it induces. In vitro assays using mouse spleen cells and flow cytometry revealed that B. bronchiseptica Ag induced high proliferation capability of lymphocytes, especially B lymphocytes, and the proliferating cells showed a significant response to interleukin (IL)-2. B. bronchiseptica Ag also enhanced the production of IL-12, a representative cytokine for cell-mediated immunity. In vivo experiments using mice showed that the injection of B. bronchiseptica Ag markedly induced Ag-specific antibody. Taken together, these results indicate that B. bronchiseptica Ag has high immunogenicity by itself.
