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.

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.

This study was designed to examine the tissue levels of interleukin-$1{\alpha}$(IL-$1{\alpha}$), interleukin-$1{\beta}$(IL-$1{\beta}$) and tumor necrosis factor-${\alpha}$(TNF-${\alpha}$) in inflamed human dental pulps and periapical lesions, and to determine the relationship between each cytokine and pulpal and periapical pathosis. The pulps used in this experiment, were obtained in routine endodontic treatment and the periapical lesions in periapical surgery after clinical diagnoses were performed. These specimens were divided into four groups as normal pulp group(control group, n=9), acute pulpitis group(n=g), chronic pulpitis group(n= 10) and periapical lesion group(n= 18) and stored in liquid N2. For extract preparation, tissues were finely minced with a scalpel, and the fragments were incubated in $0.5m\ell$ homogenizing buffer (0.1 mol/L potassium chloride, 0.02 mol/L TRIS; pH=7.6) for two hours and grinded with glass homogenizer. Debris was removed by centrifugation and supernatants were immediately tested with enzymelinked immunosorbent assay (ELISA, R&D Co., Minneapolis, USA). Following results were obtained; 1. The concentrations of IL-$1{\alpha}$ in all experimental groups were significantly higher than in control group(p<0.05). And the concentrations of IL-$1{\alpha}$ in periapical lesion group were somewhat higher than in two pulpitis groups, but the differences among those groups were not stastically significant (p>0.05). 2. The concentrations of IL-$1{\beta}$ in all experimental groups were significantly higher than in control group (p<0.05), and all the experimental groups expressed similar concentrations. 3. The concentrations of TNF-${\alpha}$ in all experimental groups were higher than in control group but only the differences between chronic pulpitis group and control group were statistically significant(p<0.05). And the concentrations of TNF-${\alpha}$ in acute and chronic pulpit is groups were higher than in periapical lesion group but only the differences between chronic pulpitis group and periapical lesion group were statistically significant (p<0.05). 4. There was significant correlation only between IL-$1{\alpha}$ and IL-$1{\beta}$ in periapical lesion group (p<0.05).

Objective: The presence of the various cytokines in human peritoneal fluid has been evaluated incompletely. Changes in cytokine levels may be related to activation of peritoneal macrophage and T-lymphocyte, development of endometriosis, and infertility. This study assesses peritoneal fluid levels of interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-10 (IL-10) and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) in infertile women with endometriosis and normal women without endometriosis. Design: Prospective and case-control study in university hospital. Materials and Methods: Cytokine levels in peritoneal fluid obtained during laparotomy or laparoscopy from 21 patients in infertile patients with endometriosis and 24 controls undergoing laparotomy or laparoscopy with no evidence of pelvic endometriosis were determined by enzyme-linked immunosorbent assay. Results: The mean levels of interleukin-6 in infertile patients with endometriosis and controls were $72.7{\pm}23.7$ pg/ml and $18.5{\pm}9.7$ pg/ml respectively (p=0.02). Similarly, the mean levels of interleukin-8 in infertile patients with endometriosis was significantly higher than that of controls ($445.0{\pm}89.6$, vs $45.1{\pm}48.4$, p=0.04). The mean concentration of interleukin-10 in infertile patients with endometriosis was significantly lower than that of controls ($1.09{\pm}0.04$ vs $2.19{\pm}0.03$, p=0.03). The level of tumor necrosis factor-${\alpha}$ was not significantly different between the two study groups. Conclusions: Increased IL-6 and IL-8 and decreased IL-10 levels in the peritoneal fluid may be related to pathogenesis in the endometriosis and infertility, suggesting that partially contribute to the disturbed immune regulation observed in infertili women with endometriosis.

Recombinant interleukin-2 (IL-2) has demonstrated as an antineoplastic agent in mice and human, but the relatively low response rates observed in clinical trials. Therefore, the present study was undertaken in order to evaluate therapeutic activities of IL-2 for the establishment of therapeutic applications. At the onset of the experiment, normal C3H/HeN mice were injected with $3{\times}10^6$ RD-995 tumor cells, murine ultraviolet radiation-induced fibrosarcoma, subcutaneously. Beginning on day 25, experimental groups were treated with a 5-day course of IL-2 (subcutaneous injection of 30,000 IU every 12 hours for 5 days). The result of this experiment revealed that RD-995 tumor grew progressively in control mice. Subcutaneous IL-2 therapy decreased tumor growth until day 23, then the tumor grew progressively. No significant difference in the survival of IL-2 therapy decreased tumor growth until day 23, then the tumor grew progressively. No significant difference in the survival of IL-2 therapy decreased tumor growth until day 23, then the tumor grew progressively. No significant difference in the survival of IL-2 treated mice were observed compared with the control mice.

Myocardial infarction is one of the leading causes of mortality globally. Currently, the pleiotropic inflammatory cytokine interleukin-6 (IL-6) is considered to be intimately related to the severity of myocardial injury during myocardial infarction. Interventions targeting IL-6 are a promising therapeutic option for myocardial infarction, but the underlying molecular mechanisms are not well understood. Here, we report the novel role of IL-6 in regulating adverse cardiac remodeling mediated by fibroblasts in a mouse model of myocardial infarction. It was found that the elevated expression of IL-6 in myocardium and cardiac fibroblasts was observed after myocardial infarction. Further, fibroblast-specific knockdown of Il6 significantly attenuated cardiac fibrosis and adverse cardiac remodeling and preserved cardiac function induced by myocardial infarction. Mechanistically, the role of Il6 contributing to cardiac fibrosis depends on signal transduction and activation of transcription (STAT)3 signaling activation. Additionally, Stat3 binds to the Il11 promoter region and contributes to the increased expression of Il11, which exacerbates cardiac fibrosis. In conclusion, these results suggest a novel role for IL-6 derived from fibroblasts in mediating Stat3 activation and substantially augmented Il11 expression in promoting cardiac fibrosis, highlighting its potential as a therapeutic target for cardiac fibrosis.

The purpose of this study was to investigate the anti-inflammatory effects and cellular mechanism of piperine on murine peritoneal macrophages. To evaluate the effects of piperine, we examined the production of nitric oxide (NO), interleukin (IL)-10 and IL-12. To investigate inhibitory mechanism of piperine, we examined the MAPKs and Ik-Ba in murine peritoneal macrophages, Piperine itself does not have any cytotoxic effect and reduced lipopolysaccharid (LPS), Poly(I:C), CpG-ODN -induced production of NO, IL-10 and IL-12 in peritoneal macrophages. Piperine inhibited the activation of extracelluar signal-regulated kinase (ERK 1/2) and c-Jun NH2-terminal kinase (JNK 1/2) not the activation of p38 and the degradation of inhibitory kappa B a (Ik-Ba) in the LPS-stimulated murine peritoneal macrophages.ln conclusion, Piperine down-regulated LPS-induced production of NO, IL-10 and IL-12, which could provide a clinical basis for anti-inflammatory properties of piperine.

Although interleukin-11 (IL-11) has been reported to be elevated in hypoxic tumors and has been associated with a poor prognosis in various cancers, little is known about its precise role in promoting metastasis in hypoxic tumors. In the present study, the molecular mechanism underlying the effects of IL-11 on MDA-MB-231 breast cancer cells migration and invasion in relation to metastasis under hypoxic conditions has been defined. Inhibition of IL-11 expression or function using small interfering RNA (siRNA) or a neutralizing antibody attenuated hypoxic MDA-MB-231 breast cancer cell migration and invasion through down-regulation of matrix metalloproteinases (MMPs) and activation of epithelial-to-mesenchymal transition (EMT) related gene expression. In addition, hypoxia-induced IL-11 increased STAT3 phosphorylation and STAT3 knockdown suppressed hypoxic MDA-MB-231 breast cancer cell invasion due to reduced MMP levels and reprogrammed EMT-related gene expression. These results suggest that one of the hypoxic metastasis pathways and the regulation of this pathway could be a potential target for novel cancer therapeutics.

Cerebral embolic infarction is the most common neurologic complication of cardiac myxoma (CM). Development of cerebral aneurysms in CM is very rare. We present a 64-year-old woman with acute cerebral infarction and multiple cerebral aneurysms complicated by CM. The aneurysms were multiple, fusiform-shaped, and located in distal branch of major cerebral arteries. The serum interleukin (IL)-6 was highly elevated, which was normalized after surgical resection of CM. There was no regression of aneurysms on follow-up neuroimaging. Multiple cerebral aneurysms in CM are rare condition. Highly elevated serum IL-6 may be associated with increased risk of cerebral aneurysmal formation.

Single nucleotide polymorphisms (SNPs) in the promoter region of the IL-1B (interleukin-1) gene have been implicated in a variety of diseases that have an inflammatory component. However, there has been significant heterogeneity among study results, especially between Caucasian and Asian populations. Recently, it has been reported that SNPs in the IL-1B gene affect transcription, according to haplotype context, and genetic association studies may be more informative if functional SNP haplotypes of population are analyzed. Therefore, we estimated the distribution of IL-1B promoter haplotypes in 433 Koreans using the three major functional IL-1B promoter SNPs (IL-1B -1464, -511, and -31) and compared the results with those in Caucasians. The difference in IL-1B promoter haplotype frequency between Korean and Caucasian populations was statistically significant. The potentially more inflammatory haplotypes had higher frequencies in Koreans when compared with Caucasians. These Korean haplotype data will be useful for future association studies between IL-1B SNPs and disease risk.
