  • This study examined the effects of dietary ${\beta}$-cyclodextrin (${\beta}CD$) on the cholesterol of blood and tissues of swine. Thirty six male castrated swine ($Landrace{\times}Yolkshire{\times}Duroc$) weighing 50 kg were randomly assigned to one of four dietary groups until their weight reached 110 kg. The groups were: basal diet without ${\beta}CD$ (control) and basal diets containing 1.5%, 3.0%, or 5.0% ${\beta}CD$. Diets and water were offered ad libitum. No significant difference was found between treatments in terms of feeding performance measured by daily intake, daily weight gain, and feed efficiency. Addition of ${\beta}CD$ to the diets significantly reduced total lipid, triglyceride and total cholesterol levels in swine blood, particularly in the group receiving 5.0% ${\beta}CD$, which showed decreases (p<0.05) of 21.9%, 55.6% and 27.7%, respectively. Cholesterol levels in back fat, loin, belly and ham portions of swine fed ${\beta}CD$ significantly differed (p<0.05) from controls, especially in the 5.0% ${\beta}CD$-fed group, with reductions of 26.0%, 27.5%, 17.9% and 18.3%, respectively. These results suggested that the addition of ${\beta}CD$ to the diet of swine could reduce their body cholesterol by decreasing the migration of cholesterol through the blood.

  • Plasma protein which has been known as one of nonspecific immunostimulators was added to feedstuff to examine its effect on the enhancement of cellular immune response in porcine immune system. A total of 40 piglets, 20 male and 20 female each, were fed for 30 days with or without plasma protein. The peripheral blood were collected and analyzed for the investigation of leukocyte subpopulations and their activities by using a panel of monoclonal antibodies specific to porcine leukocyte differentiation antigens and flow cytometry. The results obtained as follows. 1. Total weight gain, daily feed intake and feed conversion rate for 10 days were significantly improved to 56%, 20% and 22% in the piglets fed plasma protein, respectively. 2. A significant increase in N (null or non T/non B) cells was also noticed. Leukocyte proportion from piglets fed plasma protein was 20.2-24.7%, otherwise that from piglets fed without plasma protein was 12.3-13.4%, respectively. 3. A significant increase in the proportion of B cells and cells expressing poCD1 was not found in piglets fed plasma protein. 4. Reaction with monoclonal antibodies specific to adhesion molecules, poCD11a, poCD11b, poCD44 and poCD45A and poCD45B, has shown that leukocyte subpopulation from piglets fed plasma protein did not significantly higher than that from piglets fed without plasma protein. 5. Total proportion of granulocytes and monocytes was about 50% in both group and the proportion after treated with Hypaque/Ficoll was 2.7% and 5.8% in each group, respectively.

  • Cyclodextrin glucanotransferase from B. stearothermophilus KJ16 that can produce both cyclodextrin glucanotransferase and cyclodextrinase was purified by ammonium sulfate precipitation, DEAE-cellulose chromatography, Sephadex G-100 chromatography, and FPLC. The molecular weight of the purifice enzyme was about 65,000 dalton by SDS-PAGE. The optimal pH and temperature were 6.0 and $60^{\circ}C$, respectively. The enzyme was stable at $50^{\circ}C$ for 1 hr and in the pH range of 5.5 and 8.5. Mercaptoethanol and dithiothreitol inhibited the enzyme activity strongly. The enzyme produced 60% cyclodextrin(CD) from 5% soluble starch with the $^{\alpha}$, $^{\beta}$, $^{\gamma}$-CD ratio of 42:46:12. Amylopectin was the most suitable substrate with 67% conversion to CD.

  • 목 적 : H. pylori의 감염은 세균의 병독 인자, 숙주 인자, 환경 인자가 복합적으로 작용하여 다양한 위장관 병변을 일으킨다. H. pylori의 병리 기전으로 지금까지는 주로 세균의 병독성에 초점을 맞추었으나 최근에는 숙주의 위점막 면역반응이 주목을 받고 있다. 소아는 술, 담배, 약물과 같은 환경 인자의 영향이 적어 연구에 적합한 대상이며 감염 초기를 반영한다는 측면에서 중요한 의의가 있음에도 불구하고 소아에서 위점막 면역반응에 관한 연구가 거의 없다. 이에 H. pylori 감염 소아에서 위점막 림프구를 분석하여 소아에서 H. pylori 감염으로 인한 국소 면역반응의 특징을 알아보고자 하였다. 방 법 : H. pylori 양성 소화궤양군 10명, H. pylori 양성 위염군 15명, H. pylori 음성 대조군 20명에서 얻은 위전정부 생검조직에서 hematoxylin-eosin 염색과 modified Giemsa 염색을 시행하여 개정된 시드니 체계에 따라 위염의 정도를 점수화하였다. 위점막에서 림프구 면역표현형을 알기 위해 CD3, CD4, CD8 T세포와 CD20 B세포에 대한 면역조직화학염색을 시행하였으며 점막 고유층에서는 400배 고배율 현미경 하에서 $0.0625m^2$ 당 양성 림프구 수를 기록하였고, 상피세포 내에서는 100개 상피세포 당 양성 림프구 수를 기록하였다. 결 과 : 림프구 침윤은 점막 고유층에서 상피세포 내보다 확연히 많았다. 점막 고유층에서 H. pylori 양성군에서 대조군에 비해 CD3, CD4, CD8 T세포와 CD20 B세포가 유의하게 증가하였고(P<0.01) H. pylori 양성 소화궤양군은 위염군과 달리 대조군에 비해 CD8 T세포가 유의하게 증가하였다(P<0.01). 한편, 상피세포 내에서는 H. pylori 양성 소화궤양군과 위염군 모두 대조군에 비해 CD4 T세포가 유의하게 증가하였다(P<0.01). H. pylori의 밀도, 다핵형 중성구의 활동성, 만성 염증 정도와 림프구 수는 점막 고유층에서 상피세포 내보다 더 밀접한 상관관계가 있었다. 결 론: H. pylori에 감염된 소아의 국소 면역반응은 주로 위점막 고유층에서 일어나며 T세포와 B세포가 함께 관여하였다. H. pylori 양성 소화궤양군에서 점막 고유층의 CD8 T세포가 유의하게 증가하여 임상질환과 점막면역의 연관성을 추정할 수 있었다. 향후 H. pylori 감염에서 국소 면역반응으로 야기되는 점막 손상, 연령과 인종에 따른 차이, 임상질환과의 연관성 등에 대하여 더 많은 연구가 이루어져야 할 것이다.

  • For 16 years after the finding of HIV as an agent of AIDS in 1981, HIV therapeutic drugs of reverse transcriptase inhibitors (AZT, ddI, ddC, d4T) and protease inhibitors have been developed. Recent studies also were focused on a combination therapy by using HIV therapeutic drugs or natural compounds. Korean red ginseng (KRG) of natural compounds has been well known as a good reinforcement agent in Asia. The percentage of CD3+CD4+ T cell in nine HIV-infected patients without KRG treatment averaged 17.8% on baseline and decreased 15.8% after 6 months, whereas the percentage of the cell in fifteen HIV-infected patients with KRG treatment averaged 15.3% on baseline and increased up to 18.9% after the same period. The average percentage of CD3+CD8+ T cell of KRG-nontreated and KRG-treated HIV patients increased after 6 months 47.8% to 50.7% and 44.7% to 51.4%, respectively; and the average percentage of B and NK cell in the KRG-nontreated and KRG-treated HIV patients decreased 9.4% to 7.9% and 13.0% to 9.7%, 8.9% to 8.5% and 16.2% to 11.6%, respectively. KRG, therefore, didn't have any effects on the CD3+CD8+ T cell, B cell, and NK cell. However, it seems that KRG has a potential activity for stimulatiing the CD3+CD4+ T cell and some inhibition on destroying of this cell with no significance.
