  • 연구목적 : Cytokine은 유해 미생물에 대한 숙주의 방어기전으로서의 염증반응에서 숙주세포 상호간의 작용을 매개해 주는 역할을 하며, 인간의 치수조직에서도 그 존재가 확인된 바 있다. Interleukin-6와 Interleukin-10은 염증의 초기에 작용하는 cytokine으로 알려져 있으나, 치수 및 치근단 질환에서의 역할과 상호작용에 대해서는 잘 알려져 있지 않다. 본 연구에서는 치수염의 원인균으로 알려진 Prevotella nigrescens를 이용하여 백서의 치수염을 유도한 후 시간의 변화에 따른 Interleukin-6, Interleukin-10의 농도의 변화를 측정하여 이들의 치수염에서의 작용을 알아보는 것을 목적으로 한다. 방법 : 실험적으로 치수의 염증반응을 일으키기 위하여 치수염의 원인균으로 알려진 Prevotella nigrescens를 이용하였다. 실험동물의 하악절치의 incisal tip부분을 절단한 후(n=120), 치수강을 개방시켰다. 실험군에서는 Prevotella nigrescens를 멸균된 면구에 묻혀서 개방된 치수강 내에 접종하였으며, 대조군에서는 균을 접종하지 않고 멸균된 면구만을 개방된 치수강 내에 위치시켰다. 그 후 1, 2, 5일이 경과되었을 때 실험에 사용된 치아를 발치하여, 치수조직을 적출하였다. Amersham사의 ELISA kit를 사용하여 적출된 치수조직내의 Interleukin-6와 Interleukin-10의 양을 측정하였으며 그 결과를 Mann-Whitney rank sum test를 사용하여 통계학적 유의성을 검증하였다. 조직학적 검사를 위해서는 발치된 치아를 nitric acid를 사용하여 탈회시킨 후 헤마톡실린-에오신 염색을 시행한 후 관찰하였다. 결과 : 1) Interleukin-6의 농도는 균접종 후 1일, 2일, 5일 모두에서 실험군에서 대조군보다 높게 나타났으며, 균접종 1일째의 결과는 통계적 유의성이 있었다(P<0.05). 2) Interleukin-10의 농도는 균접종 후 1일, 2일, 5일 모두에서 실험군에서 대조군보다 높게 나타났으며, 균접종 1일째의 결과는 통계적 유의성이 있었다(P<0.05). 3) Interleukin-10/1nterleukin-6 ratio는 실험군과 대조군 모두에서 1일보다 2일째의 결과에서 더 높은 값을 보였으며 대조군에서는 통계적 유의성을 보였다(P<0.05). 4)조직학적 관찰결과 균접종 후 2일째의 조직표본에서는 림프구의 침윤과 부분적인 조직의 괴사 등 염증반응의 양상을 관찰할 수 있었으며, 균접종 5일째의 조직표본에서는 염증의 정도가 감소되는 양상을 확인할 수 있었다.

  • The purpose of this study was to investigate the effects of Kami boatang(KBT) on the immune cells in Balb/c mice. KBT (500mg/kg) was administerd p.o. once a day for 7 days. KBT enhanced the proliferation of thymocytes and splenocytes. KBT enhanced the subpopulation of helper T(Th) cells, but did not affect the subpopulation of Thyl/B220 cells and Th/Tc cells in splenocytes. KBT enhanced the production of ${\gamma}$-interferon and interleukin-2 in thymocytes, but decreased the production of interleukin-4. KBT enhanced the production of ${\gamma}$-interferon, interleukin-2 and interleukin-4 in splenocytes and serum. KBT suppressed the production of nitric oxide, and enhanced the phagocytic activity in peritoneal macrophages. These results suggest that KBT has a potent activity on the immune response via the increase of the production of cytokines and phagocytic activity in vivo.

  • Objective : Growth factor receptors on the tumor cells are known to be expressed highly allowing the tumor cells to bind growth factors to stimulate cellular division. Immunotoxin therapy is one of the novel approaches to the primary malignant brain tumor, and expression of cell-surface receptor is essential for the immunotoxin to have specific anti-tumor activity. Despite promising cytotoxic activity of immunotoxin, tumor responses are not curative on clinical trials, and additional studies are needed regarding various factors influencing the efficacy of the immunotoxin. The purpose of this study is to detect the expression of various growth factor receptors on brain tumor cell lines which are going to be used in these studies. Materials and Methods : The authors detected transferrin receptor(TR), insulin-like growth factor-1 receptor(IGF-1R), and interleukin-4 receptor(IL-4R) on medulloblastoma cell line(Daoy) and glioblastoma cell lines(U373 MG and T98 G) by flow cytometric analysis. Results : TR was expressed on Daoy, U373 MG, and T98 G. IGF-1R was expressed on Daoy and U373 MG, but not on T98 G. IL-4R was expressed on all cell lines tested. Conclusion : The transferrin and interleukin-4 receptors might be good targets for immunotoxin therapy. The results should be considered in additional in vitro and in vivo studies regarding immunotoxin and in establishing the proper treatment model of the immunotoxin therapy including selection of the adequate immunotoxin.

  • Objectives ; This study was to investigate the anti-cancer effects of herbal acupuncture with distilled fresh ginseng. The herbal acupuncture was injected to Chung-wan($C.V_{12}$) and Wisu($BL_{21}$) of mice that were subjected to Sarcoma-180 adbominal cancer cell and A549 human epithelial lung cancer cells in vitro. Methods : Anti-cancer effects of distilled fresh ginseng herbal acupuncture were tested by measruing Cox, Bcl-2, and Bax by using RT-PCR in A549 human epithelial lung cancer cells in vitro. And four weeks old Balb/c line male mice weighing around $20\;{\pm}\;3g$ were used to measure survival rate and anti-cancer effect to outputs of interleukin-2 and interleukin-4 using flow cytometry, possibility of mRNA menifestation using RT-PCR, and Cox mRNA. The results are as follows. Results : 1. In measuring mRNA menifestation in Cox, Bcl-2, and Bax by using RT-PCR in A549 human epithelial lung cancer cells in vitro, the result showed that fresh ginseng decreased Cox-2 which is directly involved in Inflammation process. 2. Survival rate was measured in an anti-cancer effect experiment against Sarcoma-180 abdorminal cancer. Median survival time of controlled group was 27 days, of experiment group I was 21 days, and of experiment group II was 27 days. Therefore, experiment group I showed -22.2% increase in survival rate and experiment group II showed no difference compare to controlled group. 3. There was no difference between condition group and controlled and experiment group in measuring outputs of interleukin-2 and interleukin 4 by using flow cytometry 4. In measuring outputs of interleukin-2 by using ELISA, there was no significant difference between condition group and controlled group and there was decrease in experiment group II compared to conditioned and controlled group. 5. In measuring cytokine mRNA menifestation by using RT-PCR, experiment group I showed increase of mRNA menifestation in interleukin-2,4 and $interferon-{\gamma}$ and experiment group II showed no significant difference in $interferon-{\gamma}$. Conclusion : According to the results, fresh ginseng herbal-acupuncture took a little effects in cancer. In using distilled fresh ginseng herbal acupuncture has effect on Cox-2 decrease. However, the difference in concentration of fresh ginseng showed no effect on killing cancer cell. It is assumed that inaccurate concentration of herbal acupuncture and fresh ginseng component could be the reason for this result. Therefore, future consideration will be studies on herbal acupuncture concentration.

  • Objectives: This study aimed to assess and compare the levels of interleukin-1beta (IL-$1{\beta}$) and interleukin-6 (IL-6) in the crevicular fluid around healthy implants, implants with peri-implantitis, and healthy teeth. Materials and Methods: This study evaluated 16 dental implants in 8 patients (4 males and 4 females). These patients had at least one healthy implant and one implant with peri-implantitis next to healthy teeth. The crevicular fluid was collected using absorbent cones and transferred to the laboratory. Specimens were evaluated by ELISA for interleukin levels. Data were analyzed using repeated measures ANOVA and Bonferroni tests (P<0.05). Results: Levels of IL-$1{\beta}$ in the crevicular fluid around implants with peri-implantitis were significantly higher than around healthy implants (P=0.002); the latter was significantly higher than around healthy teeth (P=0.015). A significant difference was found in the level of IL-6 in the crevicular fluid around implants with peri-implantitis and healthy implants (P=0.049) and also between implants with peri-implantitis and healthy teeth (P<0.001). Conclusion: Within the limitations of this study, significant differences exist in the levels of IL-$1{\beta}$ and IL-6 in the crevicular fluid of implants with peri-implantitis, healthy implants, and healthy teeth. More studies with larger sample sizes in different populations are necessary.

  • Objectives : Scutellariae Radix (Hwanggeum in Korean) is the root of Scutellaria baicalensis Georgi. Scutellariae Radix is well known to be used as a medicine for common cold, upper respiratory infections, and to strengthen and regulate the immune system and anemia etc. Little is understood about the roles of Scutellariae Radix in the cytokine and chemokine secretion by immune cells. This study was designed to find out the effects of Scutellariae Radix on the cytokine and chemokine secretion in human mast cells (HMC-1). Methods : We treated hwanggeum according to consistency on HMC-1 and measured cytokines and chemokines levels using flow cytometry CBA system. Results : In hwanggeum treated group, the expression of interferon-inducible protein 10 (IP-10), monocyte chemoattractant protein-1 (MCP-1), chemokine (C-X-C motif) ligand 9 (CXCL9, MIG), interleukin 8 (IL-8), interleukin 2 (IL-2), interleukin 4 (IL-4), interleukin 5 (IL-5), interleukin 10 (IL-10), and interferon ${\gamma}$ (IFN-${\gamma}$) were decreased significantly. Conclusion : These results suggest that hwanggeum may support some of immune diseases by means of amiliorating some chemokines or cytokines such as IP-10, MCP-1, MIG, IL-8, IL-2, IL-4, IL-5, IL-10, and IFN-${\gamma}$.

  • Purpose: According to the recent studies, it is shown that the polymorphism of Interleukin $1\beta$ gene is associated with the incidence of gastric cancer caused by the Helicobacter pylori infection. Interleukin $1\beta$ is a cytokine markedly inhibiting gastric acid secretion. Interleukin $1\beta$ production associated with Helicobacter pylori gastric infection may exacerbate mucosal damage including chronic gastritis and atrophic gastritis, may induce eventual neoplasia. Among these Interleukin $1\beta$ gene polymorphisms, polymorphisms at -31 portion and -511 portion may associated with these processes, eventually increase the risk of gastric cancer. We investigated the risk of gastric cancer according to the Helicobacter pylori infection and genetic polymorphism of Interleukin $1\beta$ in gastric cancer patients. Materials and Methods: 176 individuals with gastric cancer and 40 healthy controls were analyzed. Each group was divided into two groups whether they infected with Helicobacter pylori or not. DNA was extracted from the peripheral blood in all groups. The PCR-RFLP method was used for investigating the distribution of genotype of C/C, C/T, T/T at -31 portion and -511 portion. Results: T/T genotype at -511 portion was $19.3\%$ in gastric cancer cases and $10\%$ in controls, which was statistically significant. (P=0.0432) The risk of gastric cancer was increased 4.86 ($1.26\∼18.77$) in group which had T/T genotype. In gastric cancer cases, C/C genotype at 31 portion was $27.6\%$ in group with Helicobacter pylori infection and $12.8\%$ in group without infection, which was statistically significant. (P=0.0047) The risk of gastric cancer was increased 4.82 ($1.81\~12.81$) in group which had C/C genotype. Conclusion: T genotype at -511 portion among the Interleukin $1\beta$ genetic polymorphisms may be the risk factor of gastric cancer. And, with Helicobacter pylori infection, C genotype at -31 portion may be the risk factor of gastric cancer.

  • Several plant-derived cannabinoids and endogenous ligands for cannabinoid receptors such as 2-arachidonyl-glycerol have been known to inhibit interleukin-2 (IL-2) expression. In the present study, we utilized arachidonylethanolamide (AEA), a putative endogenous ligand for cannabinoid receptors, to determine whether AEA modulated the expression of IL-2. AEA inhibited phorbol 12-myristate 13-acetate (PMA) plus ionomycin (Io)-induced IL-2 protein secretion and mRNA expression in EL-4 mouse T-cells as determined by ELISA and RT-PCR, respectively. To further characterize the inhibitory mechanism of AEA at the transcriptional level, we performed promoter study for IL-2 gene in PMA/Io-stimulated EL-4 cells. AEA decreased the transcriptional activity of the nuclear factor of activated T-cells (NF-AT) as well as the IL-2 promoter activity. These results suggest that AEA suppresses IL-2 expression and that the inhibition is mediated, at least in part, through the down-regulation of NF-AT.
