In order to investigate the antitumor effect by Dangguihwalhyultang after B-l6 cells were transplanted in C57BL/6 mice, and the immune responses in mice induced by methotrexate, the extract of Dangguihwalhyultang was orally administered to the ICR mice. Experimental studies were performed for measurance of metastasis, cell cytotoxicity in vitro, life extention, weight of cancer, natural killer cell activity. productivity of interleukin-2. The results were summarized as follows: 1. Mean survival time in Dangguihwalhyultang-treated group was prolonged, as compared with control group(14.63%) significantly(P<0.05). 2. Inhibition of metastasis in Dangguihwalhyultang-treated group was higher than control group with significance on 14th day(P<0.05). 3. On the weight of solid tumor. Dangguihwalhyultang-treated group was less than control group with significance(P<0.05). 4. On the MTT assay. Dangguihwalhyultang concentration inhibited cell viability was $368.8{\mu}g/well$. 5. Natural killer cell activity in Dangguihwalhyultang-treated group was significantly increased on 100:1, 50:1 E/T(effect cell/target cell) ratio(P<0.05). 6. Production of interleukin-2 in Dangguihwalhyultang-treated group was significantly increased(P<0.05).

Interleukin-6 (IL-6), a central proinflammatory cytokine, maintains immune homeostasis and also plays important roles in cervical cancer. Therefore, we aimed to evaluate any associations of IL-6 gene polymorphisms at positions -174 and -572 with predisposition to cervical cancer in a Chinese population. The present hospital-based case-control study comprised 518 patients with cervical cancer and 518 healthy controls. Polymorphisms of the IL-6 gene were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Patients with cervical cancer had a significantly higher frequency of the IL-6 -174 CC genotype [odds ratio (OR) =1.52, 95% confidence interval (CI) = 1.06-2.19; p=0.02], IL-6 -572 CC genotype (OR =1.91, 95% CI = 1.16-3.13; p=0.01) and IL-6 -174 C allele (OR =1.21, 95% CI = 1.02-1.44; p=0.03) compared to healthy controls. When stratifying by the FIGO stage, patients with III-IV cervical cancer had a significantly higher frequency of IL-6 -174 CC genotype (OR =1.64, 95% CI =1.04-2.61; p=0.04). The CC genotypes of the IL-6 gene polymorphisms at positions -174 and -572 may confer a high risk of cervical cancer. Additional studies with detailed human papillomavirus (HPV) infection data are warranted to validate our findings.

대장균을 이용한 재조합 인체 인터루킨-2(IL_2) 생산의 최적화를 위하여 발효조건이 세포성장과 IL-2의 생산 및 재조합 세포의 안정성 등에 미치는 영향을 조사하였다. 복합배지의 경우에는 yeast extract, peptone, corn steep liquor 등이 재조합 세포성장에 좋은 효과를 나타내었다. 재조합 세포의 안정성은 IL-2 발현 억제 조건(3$0^{\circ}C$)에서는 안정하게 유지되었으나 IL-2 생산조건(42$^{\circ}C$)에서는 selection pressure를 주었을 때조차도 현격하게 감소함을 알 수 있었다. 한편 배양배지에 항생제를 첨가한 경우에도 안정성 유지에는 별로 도움이 되지 못하고 세포성장만 억제됨을 알 수 있었다. 유전자의 발현은 대수 증식 중기에서 유도했을 때가 IL-2 생산에 가장 좋은 것으로 나타났으며 IL-2 생산은 세포성장과 플라스미르내의 다른 유전자들의 발현을 상당히 저해시킴을 알 수 있었다.

Purpose: To search the salivary factors that objectively indicate an pain in myalgia patients with temporomandibular joint disorder (TMD) and determine the possibility of the factors as pain-biomarkers. Methods: Participants consisted of pain-free 15 persons (male 7, female 8, mean age±standard deviation (SD); 26.8±16.04 years) and 45 myalgia patients with TMD (male 21, female 24, mean age±SD; 27.98±13.01 years). They were divided into a pain-free group (numerical rating scale [NRS] score 0), a mild pain group (NRS 1-4), a moderate pain group (NRS 5-6), and a severe pain group (NRS 7-10) and members of all groups were age, sex matched. Interleukin-8 (IL-8) and matrix metalloprotease 9 (MMP-9) were selected as pain biomarkers, by searching the Gene Expression Omnibus database and analyzing pain-related genes. Enzyme-linked immunosorbent assays were used to measure the concentration of IL-8 and MMP-9 in the patients' saliva. Results: IL-8 and MMP-9 levels were statistically significantly higher in pain groups than in the pain-free group. Greater differences were observed in patients with acute pain (with painful duration under 3 months) than in the control group and in female patients than in male. Conclusions: Salivary IL-8 and MMP-9 may play a role as biomarkers of myalgia in patients with TMD.

백작약은 한의학에서 보기ㆍ보혈을 위한 탕제에 이용되는 구성 생약재 중의 하나로서 본 연구에서는 백작약이 면역세포를 활성화시켜 암세포의 생장을 억제할 수 있는 능력이 있는지를 확인하고자 하였다. 그 결과 백작약 조다당분획(PJ-P)는 대식 세포를 활성화시켜 그 고유기능인 탐식 기능을 항진시켰다. 또한 암세포를 저해하는데 중요한 작용을 하는 NO와 TNF-$\alpha$, IL-1 그리고 IL-6의 분비를 향상시켰다. 이렇게 PJ-P에 의해 활성화된 대식 세포는 cytokine들과 NO를 생산함으로써 시험관 내에서 암세포를 살해하였으며, 또한 PJ-P는 암세포를 이식한 마우스의 생존기간을 연장시켰다 이같은 실험결과는 백작약의 조다당분획이 항암보조제 및 면역반응조절제로 활용될 가능성이 있음을 시사한다.

The purpose of this study is to prove the efficacy of KamiBohuh-tang(KBT) on immunoregulation and the possibility of KBT as an immunoadjuvant. KBT with solid feed was administered orally once a day for 7 days to an experimental group, a solution of salt and solid feed without KBT to a control group. After a week T cell, B cell, cytokines, nitric oxide and phagocytic activity are measured. KBT enhanced the proliferation of splenocytes and the subpopulation of Th cells in splenic T-Iymphocytes, but did not affect the proliferation of thymocytes. KBT decreased the subpopulation of T-Iymphocytes in splenocytes. KBT enhanced the production of interferon-γ. interleukin-2, interleukin-4 in mice serum and the phagocytic activity in peritoneal macrophages but it suppressed the production of nitric oxide. These results suggest that KBT is a potent prescription on immune response via the increase of the proliferation of splenocytes, the production of cytokines from splenic Th cells and the phagocytic activity in vivo.

The essential oil fraction was obtained from the underground parts o of Ligusticum chuanxiong (Umbelliferae) by steam distillation, and its main components, Z-ligustilide and butylidene phthalide, were isolated by column chromatography. Its essential oil fraction and the isolated main components were examined for effects on their anti-inflammatory properties in RAW 264.7 macrophage cells to develop a new natural anti-inflammatory drug. The results showed that the L. chuanxiong essential oil fraction and its main components, Z-ligustilide and butylidene phthalide, inhibited the production of nitric oxide significantly in lipopolysaccharide (LPS)-treated RAW 264.7 cells. LPS-induced interleukin-$1{\beta}$ (IL-$1{\beta}$), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-$\alpha$) production was also decreased in a dose-dependent manner. In addition, western blot analysis revealed that the L. chuanxiong essential oil fraction and also its main components, Z-ligustilide, and butylidene phthalide reduced the expression levels of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS).

The objective of the present study was to test the effect of platelet-activating factor (PAF) on rat alveolar macrophages. PAF alone did not stimulate superoxide secretion from alveolar macrophages. However, PAF $(10^{-5}\;M)$ significantly enhanced phagocytic activator zymosan-induced superoxide secretion from alveolar macrophages. This enhancement of PAF plus zymosan was 30% above the sum of the separate effects of PAF and zymosan. Similarly, PAF $1.3{\times}(10^{-5}\;M)$ was not a direct stimulant of alveolar macrophages, as it had no stimulatory effect on chemiluminescence generation, but potentiated zymosan-induced activation of chemiluminescence, i.e., 162% above the separate effects of each stimulant. PAF $10^{-16}{\pm}10^{-6}\;M$ also failed to stimulate IL-1 production from alveolar macrophages. In contrast, when both PAF $10^{-10}\;M$ and lipopolysaccharide(LPS) $(1 {\mu}g/ml)$ were added together at the initiation of the culture, IL-1 production was significantly increased indicating the potentiative effects of PAF on IL-1 production by alveolar macrophages. Collectively, these data suggest that PAF alone does not activate the release of bioactive products from alveolar macrophages. However, PAF appears to act as a priming mediator that potentiates stimuli-induced macrophage activity. These novel actions of PAF prove its role as a potent mediator of inflammatory and immune responses in the lung.

목적 :천축황(天竺黃)이 골대사에 미치는 영향을 검토하고자 생쥐의 골세포를 이용하여 골흡수 억제 효과를 관찰하였다. 방법 :$Interleukin-1{\beta}\;(IL-1{\beta})$는 시험관내에서 osteoblast를 조절하는 것으로 알려져 있는데, 천축황(天竺黃)이 $IL-1{\beta}$ 유발된 $PGE_2$, 생성에 관한 영향을 관찰하였다. 결과 :천축황(天竺黃)는 osteoblast체 독성을 나타내지 않았으며, $PGE_2$ 생성을 억제하였다. 특히, 천축황(天竺黃)을 1시간동안 전처리한 경우 $PGE_2$의 합성을 억제하여 골세포 보호효과가 인정되었으며, 또한 골 흡수인자인 $IL-1{\beta}$에 의해 유발된 alkaline phosphatase의 활성도 억제하였는데, 천축황(天竺黃) 전처리후 16시간째에 훨씬 높은 억제효과를 나타내었다. 유사하게 천축황(天竺黃)을 1시간 동안 전처리한 경우 osteocalcin의 생성이 증가되었다. 또한, calcitonin이 나타내는 osteoclast및 osteoblast 함유세포에서 골 흡수를 억제하였다. 결론 :천축황(天竺黃)은 osteoclast가 매개된 골흡수를 억제하는 효과가 인정되었다.
