  • In order to know the pathogenesis of adult respiratory distress syndrome (ARDS) in association with the oxidative stress by neutrophils, the role of platelet activating factor (1-0-alkyl-2-acetyl-snglycero-3-phosphocholine, PAF) was investigated during acute lung injury induced by interleukin- $1{\alpha}$ (IL-1) in rats. An insufflation of IL-1 into the rat's trachea increased the acetyltransferase activity in the lung and the increase of PAF content was followed. As evidences of acute lung injury by neutrophilic respiratory burst, lung leak index, myeloperoxidase activity, numbers of neutrophils in the bronchoalveolar lavage fluid, neutrophilic adhesions to endothelial cells and NBT positive neutrophils were increased after IL-1 treatment. In addition, a direct instillation of PAF into the trachea caused acute lung leak and the experimental results showed a similar pattern in comparison with IL-1 induced acute lung injury. For the confirmation of oxidative stress during acute lung leak by IL-1 and PAF, a histochemical electron microscopy was performed. In IL-1 and PAF treated lungs of rats, the deposits of cerrous perhydroxide were found. To elucidate the role of PAF, an intravenous injection of PAF receptor antagonist, WEB 2086 was given immediately after IL-1 or PAF treatment. WEB 2086 decreased the production of hydrogen peroxide and the acute lung leak. In ultrastructural study, WEB 2086 mitigated the pathological changes induced by IL-1 or PAF. The nuclear factor kappa B (NFkB) was activated by PAF and this activation was inhibited by WEB 2086 almost completely. Based on these experimental results, it is suggested that the PAF produced in response to IL-1 through the remodeling pathway has the major role for acute lung injury by neutrophilic respiratory burst. In an additional experiment, we can also come to conclude that the activation of the NFkB by PAF is thought to be the fundamental mechanism to initiate the oxidative stress by neutrophils causing release of proinflammatory cytokines and activation of phospholipase $A_2$.

  • The purpose of this study was to investigate probiotic characteristics and immune enhancing effects of Bifidobacterium (B.) longum KBB1-26 and BIF-4, B. breve KBB5-22 isolated from human intestine for probiotic use in humans and animals. We measured acid, bile and heat tolerance, antimicrobial activity against pathogenic bacteria, Escherichia (E.) coli, Salmonella (S.) Enteritidis, Staphylococcus (S.) aureus, and Listeria (L.) monocytogenes. Immune enhancing effects of B. longum and B. breve were investigated by measuring nitric oxide (NO), nuclear factor ($NF-{\kappa}b$), $interleukin-1{\beta}$ ($IL-1{\beta}$), interleukin-6 (IL-6), interleukin-12 (IL-12) and tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) in RAW 264.7 cells or RAW BLUE cells. B. longum KBB1-26 was survived at pH 2.0. B. longum KBB1-26 and BIF-4, B. breve KBB5-22 also showed tolerance to 0.3% of oxgall bile salt. B. longum KBB1-26 was able to survive at $70^{\circ}C$ and $80^{\circ}C$ for 20 min. KBB1-26 showed the antimicrobial inhibition zone to pathogenic bacteria such as E. coli (12 mm), S. Enteritidis (14 mm), S. aureus (14 mm) and L. monocytogenes (41 mm). The production of NO ($4.5{\pm}0.00{\mu}M/mL$) and $IL-1{\beta}$ ($39.7{\pm}0.55pg/mL$) of KBB1-26 significantly higher than BIF-4 and KBB5-22, respectively. In addition, KBB1-26 and KBB5-22 induce the production of high level of $TNF-{\alpha}$ and IL-6 in macrophages. Collectively, B. longum KBB1-26 have acid, bile, heat tolerance, antimicrobial activity and immune enhancing effects. These results suggest that KBB1-26 can be used as probiotics for humans and animals.

  • Purpose : High interleukin-1 beta(IL-$1{\beta}$) expression in the skin biopsy specimens of patients with Henoch-$Sch\ddot{o}nlein$ Purpura(HSP) has been observed. We examined IL-$1{\beta}$ gene polymorphism in patients with HSP. The purpose of this study is to examine the relationship between IL-$1{\beta}$ gene polymorphism and renal involvement in HSP. Methods : Patients from mideast Korea with HSP were studied. All patients had at least 6 months of follow up. Patients and ethnically matched controls were genotyped for IL-$1{\beta}$ gene polymorphism by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP). Results : Thirty-four patients(all younger than 15 years old) who had been diagnosed with HSP and 27 controls were examined. No allele or genotype differences between the HSP and control groups were observed. No significant association between the carriage of IL-$1{\beta}$(-511) T allele and renal involvement(P=0.525, OR:1.417, CI:0.545-3.686) was found. Conclusion : In unselected patients with HSP, carriage of IL-$1{\beta}$(-511) T allele does not appear to influence renal involvement.

  • BACKGROUND/OBJECTIVES: We investigated the anti-osteoarthritic effects of deer bone extract on the gene expressions of matrix metalloproteinases (MMPs) and collagen type II (COL2) in interleukin-$1{\beta}$-induced osteoarthritis (OA) chondrocytes. MATERIALS/METHODS: Primary rabbit chondrocytes were treated as follows: CON (PBS treatment), NC (IL-$1{\beta}$ treatment), PC (IL-$1{\beta}+100{\mu}g/mL$ glucosamine sulphate/chondroitin sulphate mixture), and DB (IL-$1{\beta}+100{\mu}g/mL$ deer bone extract). RESULTS: The results of the cell viability assay indicated that deer bone extract at doses ranging from 100 to $500{\mu}g/mL$ inhibits cell death in chondrocytes induced by IL-$1{\beta}$. Deer bone extract was able to significantly recover the mRNA expression of COL2 that was down-regulated by IL-$1{\beta}$ (NC: 0.79 vs. DB: 0.87, P < 0.05) and significantly decrease the mRNA expression of MMP-3 (NC: 2.24 vs. DB: 1.75) and -13 (NC: 1.28 vs. DB: 0.89) in OA chondrocytes (P < 0.05).CONCLUSIONS: We concluded that deer bone extract induces accumulation of COL2 through the down-regulation of MMPs in IL-$1{\beta}$-induced OA chondrocytes. Our results suggest that deer bone extract, which contains various components related to OA, including chondroitin sulphate, may possess anti-osteoarthritic properties and be of value in inhibiting the pathogenesis of OA.

  • Purpose: Febrile seizures are induced by fever and are the most common type of seizures in children. Although numerous studies have been performed on febrile seizures, their pathophysiology remains unclear. Recent studies have shown that cytokines may play a role in the pathogenesis of febrile seizures. The present study was conducted to identify potential links between serum interleukin-1beta (IL-$1{\beta}$), tumor necrosis factor-alpha (TNF-${\alpha}$), and febrile seizures. Methods: Ninety-two patients with simple or complex febrile seizures (46 patients per seizure type), and 46 controls with comparable age, sex, and severity of temperature were enrolled. Results: The median concentrations of serum IL-$1{\beta}$ in the simple, complex febrile seizure, and control groups were 0.05, 0.1, and 0.67 pg/mL, respectively (P=0.001). Moreover, the median concentrations of TNF-${\alpha}$ in the simple, complex febrile seizure, and control groups were 2.5, 1, and 61.5 pg/mL, respectively (P=0.001). Furthermore, there were significant differences between the case groups in serum IL-$1{\beta}$ and TNF-${\alpha}$ levels (P<0.05). Conclusion: Unlike previous studies, our study does not support the hypothesis that increased IL-$1{\beta}$ and TNF-${\alpha}$ production is involved in the pathogenesis of febrile seizures.

  • 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.
