The effect of WK101 on compound 48/80-induced anaphylaxis was studied in rat. WK101 was found to exhibit a inhibitory activity on the compound 48/80-induced anaphylaxis. WK101 also inhibited the serum histamine release induced in anaphylaxis by compound 48/80. The effect of WK101 on the histamine release from rat peritoneal mast cells was studied. WK101 ($10^{3}-1mg/ml$) inhibited the histamine release induced by compound 48/80($5{\;}\mu\textrm{g}/ml$) in rat peritoneal mast cells. To clarify the mechanism of these inhibitons, we investigated the effects of WK101 on cAMP and intracellular calcium content of rat peritoneal mast cell. The content of cAMP in mast cells, when WK101 was added, was increased transiently, and was significantly increased more 53 fold at 10 sec than that of basal cells. Moreover, WK101 inhibited intracellular calcium release induced by compoound 48/80. This results suggest that WK101 may be useful for the prevention and treatment of allergy-related disease.

This experimental research has been done to study the effects of Sipjeondaebo-tang(SOT) on the anti-allergic reaction. We found the several important results from the research which has been performed by two experiments toward immediately type and delayed type in order to study the effects of SDT on hypersensitivity response to mice. The results obtained from our research are as following. The survival rate of one group to which we injected only the compound 48/80 is almost 0% according to its density and timing test. In the other hand, the survival rates of the other group to which we injected both of the compound 48/80 and SDT are 20%, 10%, 30%, 10%, 40% and 70% according to 0.025, 0.05, 0.1, 0.25 0.5 and 1 (mg/g) of compound 48/80. Time dependency test also shows the 30% and 20% survival rates in 5 and 10 minutes. SDT revealed the significantly inhibitory effect on Compound 48/80 induced Mast cell degranulation. SDT showed the significantly inhibitory effect in the delayed type hypersensitivity response to picry1 chloride. SDT showed the significantly inhibitory effect in the delayed type hypersensitivity response to sheep red blood cell. Our research provides the important evidence that SDT is benificial to the prevention and treatment of allergy related diseases.

We evaluated the efficacy of health education in reducing indoor arthropod allergens in Seoul. The mite control measures comprised the use of mite-proof mattress and pillow coverings, regular washing of potentially infested materials, maintenance of a low humidity, removal of carpets, and frequent vacuum cleaning. Cockroach control measures included trapping, application of insecticides, and protecting food. Of 201 homes enrolled in October 1999, 63 volunteers were included in a 2-year follow-up survey between April 2000 and January 2002. Before intervention, the density of mites/g of dust varied greatly; 27.1/g in children's bedding, 20/g in adult bedding, 7.2/g on the floors of children's bedrooms, 6.8/g in sofas, 5.9/g on the floors of adult's bedrooms, 3.9/g on living room floors, 3.7/g in carpets, and 1.9 mites/g on kitchen floors. The predominant mite species and house percentages infested were; Dermatophagoides farinae $93\%$, D. pteronyssinus $9\%$, and Tyrophagus putrescentiae $8\%$. Comparing 1999 and 2001 infestations, before and after 25 mo of education, mite abundance was reduced by $98\%$, from 23.7 to 0.57 mites/g of dust. In 1999, cockroaches were detected in $62\%$ homes: $36\%$ Blattella germanica and $35\%$ Periplaneta spp., including $9\%$ double infestations of B. germanica and P. americana. Following intervention, cockroach infestation rates decreased to $22\%$ of houses in 2000 and $23\%$ in 2001. We conclude that continuous and repetitive health education resulted in the effective control of domestic arthropods.

This study aimed to investigate the effects of Sesami Semen on the itching and anti-allergic inflammation mechanism related with cytokine, chemokine, histamine, $\beta$-hexosaminidase, NF-$\kappa$B, and free radical, and it was concluded as follows : 1. Sesami Semen did not show any cytotoxicity at the range of con-centration (1-250 ${\mu}g/m\ell$) on the human fibroblast cell (hFCs). 2. Sesami Semen reduced the gene expressions of IL-8, TNF-$\alpha$, IL-6 mRNA comparing with control. 3. Sesami Semen reduced the levels of IL-6, IL-8, MCP-1 within THP-1 cell depending on the concentration, and especially significantly reduced the the levels of IL-6, MCP-1 at all the concentration. 4. Sesami Semen significantly decreased the histamine secretion on HMC-1 at all the concentration. 5. Sesami Semen decreased the $\beta$-Hexosaminidase secretion 6.2% at 10 ${\mu}g$/ml conc., 58.3% at 100 ${\mu}g$/ml conc. and 63.2% at 200 ${\mu}g$/ml conc., respectively. And IC50 (${\mu}g$/ml) was 158.25 ${\mu}g$/ml. 6. Sesami Semen significantly suppressed the activity of NF-$\kappa$B promoter depending on the concentration. 7. Sesami Semen decreased the production of reactive oxygen species (ROS) and DPPH generation depending on the concentration. As judged with above results, the effects of Sesami Semen on the anti-allergic inflamation would be recognized, and it could be applied on the medicinal sources for prevention or treatment of several allergy disease. And more studies are needed furthermore with the seperation of effective materials.

Objectives : The aim of this study was to observe prevention of allergic reactions of Sweet Bee Venom (removing enzyme components from Bee Venom). Methods: Content analysis of Sweet Bee Venom and Bee Venom was rendered using HPLC method and characterization of Anti-Sweet Bee Venom in Rabbit Serum. Clinical observation was conducted for inducement of allergic responses to Sweet BV. Results : 1. Analyzing melittin content using HPLC, Sweet BV contained 34.9% more melittin than Bee venom pharmacopuncture at same concentration. 2. Observing chromatogram of HPLC, removal of the enzyme was successfully rendered on Sweet BV. 3. The anti-serum of Sweet BV showed high titers against melittin and bee venom and relatively low titer against phospholipase A2. 4. After conducting approximately 3,000 cases of Sweet BV administration, not a single case of generalized anaphylatic reaction occurred in clinical observation. 5. Mild compared to the bee venom pharmacopuncture, Sweet BV showed some acute hypersensitive reactions of edema, itchiness, and aching locally. 6. Sweet BV was administered on six patients with previous history of suffering from generalized acute hypersensitive reactions with the bee venom. None of the patients showed allergic reactions with Sweet BV, suggesting it can effectively prevent anaphylatic shock which may occur after the bee venom pharmacopuncture procedure. Conclusion : Summarizing above results, Sweet Bee Venom appears to be an effective measurement against allergic reactions from the bee venom pharmacopuncture especially against anaphylatic shock.

Objectives: This study investigated the prevalence and characteristics of comorbid conditions in patients exposed to ionizing radiation and those who were involved in the Soviet-Afghan war. Methods: This study analyzed the frequency and spectrum of morbidity and comorbidity in patients over a long-term period (30-35 years) following exposure to ionizing radiation at the Semipalatinsk nuclear test site or the Chornobyl nuclear power plant, and among participants of the Soviet-Afghan war. A cohort study, both prospective and retrospective, was conducted on 675 patients who underwent comprehensive examinations. Results: Numerical data were analyzed using the Statistica 6 program. The results are presented as the mean±standard deviation, median, and interquartile range (25-75th percentiles). The statistical significance of between-group differences was assessed using the Student t-test and Pearson chi-square test. A p-value of less than 0.05 was considered statistically significant. We found a high prevalence of cardiovascular diseases, including hypertension (55.0%) and cardiac ischemia (32.9%); these rates exceeded the average for this age group in the general population. Conclusions: The cumulative impact of causal occupational, environmental, and ultra-high stress factors in the combat zone in participants of the Soviet-Afghan war, along with common conventional factors, contributed to the formation of a specific comorbidity structure. This necessitates a rational approach to identifying early predictors of cardiovascular events and central nervous system disorders, as well as pathognomonic clinical symptoms in this patient cohort. It also underscores the importance of selecting suitable methods and strategies for implementing treatment and prevention measures.

Purpose: Proton-pump inhibitors (PPIs) are frequently used to treat gastroesophageal reflux disease (GERD) in children, but recent evidence suggests a potential association between PPI treatment and some types of infections. The aim of this study was to assess the effectiveness of Lactobacillus rhamnosus GG (LGG) for the prevention of gastrointestinal and respiratory tract infections in children with GERD treated with PPI (omeprazol). Methods: Children younger than 5 years with GERD were assigned by a computer-generated list to receive LGG (10⁹ colony-forming units) or placebo, twice daily, concomitantly with PPI treatment for 4-6 weeks; they were followed up for 12 weeks after therapy. The primary outcome measures were the percentage of children with a minimum of one episode of respiratory tract infection and the percentage of children with a minimum of one episode of gastrointestinal infection during the study. Results: Of 61 randomized children, 59 patients (LGG n=30; placebo n=29, mean age 11.3 months) were analyzed. There was no significant difference found between the LGG and placebo groups, either for the proportion of children with at least one respiratory tract infection (22/30 vs. 25/29, respectively; relative risk [RR] 0.85, 95% confidence interval [CI] 0.66-1.10) or for the proportion of children with at least one gastrointestinal infection (9/30 vs. 9/29, respectively; RR 0.97, 95% CI 0.45-2.09). Conclusion: LGG was not effective in the prevention of infectious complications in children with GERD receiving PPI. Caution is needed in interpreting these results, as the study was terminated early due to slow subject recruitment.

Purpose : An understanding of the immunological process is required if primary prevention of atopic diseases is to be developed in early childhood. But, it is too hard to distinguish atopy from nonatopy under the age of two clinically, because the expression of phenotype and cytokines is vague in early childhood. We evaluated DNA methylation changes at Th2 interleukin-4 gene in peripheral blood from atopic children. Methods : We selected 15 allergic children(mild : eight, moderate to severe : seven) and seven normal controls by using family allergy scores and clinical histories. We measured Total IgE and Der f II specific IgE levels and cultured peripheral blood mononuclear cells with Der f II stimulation and extracted DNA from Der f II specific T cells. We examined the change of CpG methylation in DNA from atopic and nonatopic children. Results : In T cells from normal children, IL-4 DNA were predominantly methylated; otherwise, CpG demethylation occurred in Der f II specific T cells from allergic children. Conclusion : IL-4 DNA methylation changes occurred in T genes from allergic children and DNA methylation assay in early childhood.

Background: There have been no large-scale population-based studies to estimate the subsequent risk of primary liver cancer (PLC) among patients with pyogenic liver abscess (PLA). This study aimed to provide relevant data. Materials and Methods: The Taiwan Longitudinal Health Insurance Database for the years 2000 and 2005 was used. The PLA group were adult inpatients who were newly diagnosed with PLA from 2000 to 2008. The control group was randomly selected and matched with the PLA group in terms of age, sex, and date in which medical treatment was sought other than for PLA. Results: There were 1,987 patients each in the PLA and control groups. In total, 56 had PLC, 48 (2.4%, 601.5 per 100,000 person-years) from the PLA group, and 8 from the control group. After adjusting for potential covariates, the hazard ratio of PLC for the PLA group was 3.4 times that of the control group (95% confidence interval = 1.6-7.3, p <0.001). The PLC risk for the PLA group was significantly higher within the first year after PLA diagnosis (hazard ratio: 35.4) as compared with the control group and became insignificant (hazard ratio: 2.0, 95% confidence interval = 0.8-4.9) more than one year after PLA diagnosis. Conclusions: Patients with PLA have a higher rate of PLC than matched controls, especially within the first year after the diagnosis of PLA, suggesting PLA is a warning sign for PLC.
