Objective : This experiment was designed to investigate the effect of the GYZB hot water extract & ultra-fine powder on the Alzheimer's disease model induced by amyloid ${\beta}$ protein (${\beta}A$). Method : We measured the effects of the GYZB hot water extract on expression of $IL-1{\beta}$, IL-6 mRNA and production of IL-6, $TNF-{\alpha}$ in the BV2 microglial cell line treated with lipopolysaccharide (LPS). The effects of the GYZB hot water extract & ultra-fine powder on (1) the behavior, (2) expression of $IL-1{\beta}$ and $TNF-{\alpha}$, (3) glucose in serum, (4) the infarction area of the hippocampus, and brain tissue injury in mice induced with Alzheimer's diseased by ${\beta}A$ were investigated. Results : The GYZB hot water extract suppressed the expression of $IL-1{\beta}$ and IL-6 mRNA and significantly suppressed the production of IL-6 and $TNF-{\alpha}$ in the BV2 microglial cell line treated with LPS. The GYZB hot water extract & ultra-fine powder showed a significant inhibitory effect on the memory deficit of the mice with Alzheimer's disease induced by ${\beta}A$ in the Morris water maze experiment, which measured stop-through latency and distance movement-through latency. The GYZB ultra-fine powder significantly suppressed the expression of $IL-1{\beta}$ and $TNF-{\alpha}$ protein, and the GYZB hot water extract significantly suppressed the expression of $TNF-{\alpha}$ protein in the microglial cell of mice with Alzheimer's disease induced by ${\beta}A$. The GYZB hot water extract & ultra-fine powder reduced the infarction area of hippocampus in the mice with Alzheimer's disease induced by ${\beta}A$. Conclusions : These results suggest that GYZB hot water extract & ultra-fine powder may be effective for the prevention and treatment of Alzheimer's disease. Investigation into the clinical use of GYZB for Alzheimer's disease is suggested for future research.

Anthrax lethal toxin, which consists of two separate protein, protective antigen (83 KDa) and lethal factor (85 KDa) is responsible for major symptoms and death from systemic infection of Bacillus anthracis. High concentrations of this toxin are cytolytic to macrophages, whereas sublytic concentrations of lethal toxin induce these cells to produce interleukin $1{\beta}$ ($IL-1{\beta}$). It is proposed that melatonin and dehydroepiandrosterone (DHEA) may play an important role in modifying immune dysfunction. In this study, we investigated whether or not melatonin and DHEA could prevent $IL-1{\beta}$ production that is induced by anthrax lethal toxin in mouse peritoneal macrophages. Treatment of melatonin or DHEA alone, as well as together, prevented the production of $IL-1{\beta}$ caused by anthrax lethal toxin. We found that melatonin at a concentration of $10^{-6}-10^{-7}$ M inhibits $IL-1{\beta}$ production induced by anthrax lethal toxin. As expect, treatment of DHEA at a concentration $10^{-6}-10^{-7}$ M also suppressed production of $IL-1{\beta}$ by lethal toxin stimulated macrophages. The results of these studies suggest that melatonin and DHEA, immunomodulators, may have an important role in reducing the increase of cytokine production in anthrax lethal toxin-treated macrophages.

Purpose : Febrile seizure (FS) is the most common type of seizure. The role of genetic factors in FSs has long been recognized. A positive family history can be elicited in 25-40% of patients with FSs; nonetheless, the genes responsible for FSs in the majority of the population remain unknown. Interleukin-$1{\beta}$ ($IL-1{\beta}$) is a pro-inflammatory cytokine that acts as an endogenous pyrogen. Thus, $IL-1{\beta}$ could be involved in the pathophysiology of FSs. Methods : To determine whether or not single nucleotide polymorphisms of the $IL-1{\beta}$ gene are associated with susceptibility to simple FSs, $IL-1{\beta}$ promoter -31 and -511 genotyping was performed by means of polymerase chain reaction-restriction fragment (PCR-RF) length polymorphism in 40 FS patients (20 sporadic and 20 familial FS patients) and 33 controls. Results : There were no significant differences in the frequencies of -31 C/T and -511 C/T in the $IL-1{\beta}$ promoter gene, between simple FS patients and controls. Conclusion : The frequency of CT/CT increased relatively in familial FS patients. A study examining a larger number of FS patients is needed.

This study investigated the effects of Oligonol intake on cortisol, interleukin (IL)-$1{\beta}$, and IL-6 concentrations in the serum at rest and after physical exercise loading. Nineteen healthy sedentary male volunteers participated in this study. The physical characteristics of the subjects were: a mean height of $174.2{\pm}2.7$ cm, a mean weight of $74.8{\pm}3.6$ kg and a mean age of $22.8{\pm}1.3$ years. Each subject received 0.5 L water with Oligonol (100 mg/day) (n = 10) or a placebo (n = 9) daily for four weeks. The body composition, the white blood cell (WBC) and differential counts as well as the serum cortisol, IL-$1{\beta}$, and IL-6 concentrations were measured before and after Oligonol intake. The cortisol concentration and serum levels of IL-$1{\beta}$ and IL-6 after Oligonol intake were significantly decreased compared to before treatment (P < 0.01, respectively). In addition, the rate of increase of these factors after exercise was decreased compared to the placebo group. There was no change in the WBC and differential cell counts. These results suggest that oral Oligonol intake for four weeks had a significant effect on inhibition of inflammatory markers in healthy young men.

Background: This research was performed to investigate the effects of Pulsatilla Koreana NAKAI pharmacopuncture (PPA) therapy on intestinal disease in rats with dextran sulfate sodium (DSS)-induced colitis. Methods: The subjects were divided into five groups : A control group, saline group, pharmacopuncture group PPA1 ($0.2mg/1kg/40{\mu}{\ell}$), pharmacopuncture group PPA2 ($0.5mg/1kg/40{\mu}{\ell}$), and pharmacopuncture group PPA 3($1mg/1kg/40{\mu}{\ell}$). The experimental model of colitis was induced by infection of dextran sulfate sodium (DSS) for eighteen days. After colitis was induced, PPA therapy was practiced on the Chunchu (ST25) once every two days for a total six times. Thereafter Disease Activity Index (DAI), colon length, damage to the colonic mucosa, body weight, IL-6, IL-10, $IL-1{\beta}$, $IFN-{\gamma}$, $TNF-{\alpha}$, $TGF-{\beta}1$, IL-23 and IL-17 were measured. Results: The results were as follows. 1. DAI was significantly decreased in the PPA groups. 2. Colon length was significantly increased in the PPA groups. 3. Damage of colonic mucosa was observed less in the PPA groups. 4. Body weight was significantly increased in the saline group and the PPA groups. 5. The PPA2 group showed a significant decrease in the intensity of IL-6, $IL-1{\beta}$, $IFN-{\gamma}$ and $TNF-{\alpha}$ levels and the mean of IL-23. 6. The PPA3 group showed a significant increase in the intensity of IL-10 and $TGF-{\beta}1$ levels. 7. No significant differences were shown in the mean of IL-17. Conclusion: These results suggest that PPA therapy on Chunchu (ST25) can be used as an effective treatment for inflammatory bowel disease.

Extracellular interleukin 1 alpha (IL-$1{\alpha}$) released from keratinocytes is one of the endpoints for in vitro assessments of skin irritancy. Although cells dying via primary skin irritation undergo apoptosis as well as necrosis, IL-$1{\alpha}$ is not released in apoptotic cells. On the other hand, active secretion has been identified in interleukin-1 receptor antagonist (IL-1ra), which was discovered to be a common, upregulated, differentially-expressed gene in a microarray analysis performed with keratinocytes treated using cytotoxic doses of chemicals. This study examined whether and how IL-1ra, particularly extracellularly released IL-1ra, was involved in chemically-induced keratinocyte cytotoxicity and skin irritation. Primary cultured normal adult skin keratinocytes were treated with cytotoxic doses of chemicals (hydroquinone, retinoic acid, sodium lauryl sulfate, or urshiol) with or without recombinant IL-1ra treatment. Mouse skin was administered irritant concentrations of hydroquinone or retinoic acid. IL-1ra (mRNA and/or intracellular/extracellularly released protein) levels increased in the chemically treated cultured keratinocytes with IL-$1{\alpha}$ and IL-$1{\beta}$ mRNAs and in the chemically exposed epidermis of the mouse skin. Recombinant IL-1ra treatment significantly reduced the chemically-induced apoptotic death and intracellular/extracellularly released IL-$1{\alpha}$ and IL-$1{\beta}$ in keratinocytes. Collectively, extracellular IL-1ra released from keratinocytes could be a compensatory mechanism to reduce the chemically-induced keratinocyte apoptosis by antagonism to IL-$1{\alpha}$ and IL-$1{\beta}$, suggesting potential applications to predict skin irritation.

The study was designed to investigate the mechanism of Patholoobi Caulis freeze dried powder (PCF) on the regional cerebral blood flow (rCBF) and mean arterial blood pressure (MABP) in normal rats and cytokines production ($IL-1{\beta}$, $TNF-{\alpha}$, IL-10, $TGF-{\beta}$) in cerebral ischemic rats. The results in normal rats were as follows ; Increase of PCF-induced rCBF was significantly inhibited by pretreatment with methylene blue (10 ${\mu}g/kg$, I.p.), an inhibitor of guanylate cyclase, and was inhibited by indomethacin (1 mg/kg, i.p.), an inhibitor of cyclooxygenase. Increase of PCF-induced MABP was decreased by pretreatment with methylene blue, but was increased by indomethacin. These results suggested that the mechanism of action PCF was mediated by cyclic 3',5'-guanosine monophosphate. The results in cerebral ischemic rats were as follows ; In cytokine production in serum from femoral arterial blood 1 hr after middle cerebral arterial occlusion, PCF (10 mg/kg. i.p.) significantly decreased $IL-1{\beta}$ and $TNF-{\alpha}$ production, and increased IL-10 production compared with control group. In cytokine production in serum from femoral arterial blood 1 hr 1 hr after reperfusion, PCF (10 mg/kg, i.p.) significantly decreased $IL-1{\beta}$ production, and incresed IL-10 production compared with control group. These results suggested that PCF was significantly and stably increased regional cerebral blood flow by inhibiting $IL-1{\beta}$ production, and by accelerating IL-10 production.

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.
