PURPOSE: Atopic dermatitis is a chronic, inflammatory relapsing skin disease fre- quently seen in children with a history of food allergy. Recently, acute allergic reaction to egg in patients with atopic dermatitis who have never been exposed to egg white protein has been reported. The pattern of antigen-antibody reaction by means of IgE and IgG western blotting was analysed to evaluate the possibility of non- dietary sensitization. METHODS: Total 16 children(<3 years old) with egg allergy were enrolled. Eight patients of them had never ingested egg before(Non-dietary sensitization, NDS) and the other 8 patients had a history of previous egg ingestion without significant clinical symptoms(Dietary sensitization, DS). Egg proteins were analysed by SOS-PAGE and antigen-antibody reaction by means of IgE and IgG was deteded by Western-Blotting. RESULTS: The pattern of IgE antibodies to egg white protein were similar in the two groups. IgG Western blotting to egg white in the two groups, the ovotran sferrine and ovalbumin were significantly bound by 100% of sera, respectively. In DS patients, specific IgG antibodies to ovomucoid was significantly bound by 87% (7/8) of sera whereas only 38%(3/8) of sera had detectable specific IgG antibodies against ovomucoid in NDS patients. CONCLUSION: Theses results suggest that specific IgE to egg white related to exposure of egg white protein regar specific IgG to ovomucoid is related to dietary ingestion of egg. Specific IgG to ovalbumin and ovotrans-ferrine show good clinical correlation, further study might be essential to clarify to this hypothesis.

BACKGROUND AND OBJECTIVE: Murine system for studying allergic diseases has been popular in the fields of food allergy and development of their therapeutic strategies. However, there has been no information about the age-dependent changes of natural immune responses of naive C3H/HeJ mice. The purpose of this study was to evaluate the age-dependent changes of B and T-cell mediated immunologic parameters in naive C3H/HeJ mice, which can provide information for experimental planning and analysis of research results. SUBJECTS AND METHODS: Eight naive, female, 5-week-old C3H/HeJ mice were grown under the regular mouse chow feeding conditions for 6 weeks. Sera were obtained at week (w) 5, w6, w8 and w10 for measuring total and chow-specific IgE, IgG1 and IgG2a antibodies. Splenocyte proliferation (at w8 and w10) and cytokine production (at w6, w8 and w10) were evaluated with or without Con A stimulation with pooled splenocytes from two mice of each age group. Serum antibodies and cytokines (IL-4, IL-5, IL-12, INF-gamma, TGF-beta1) were measured by ELISA. Using RT-PCR, IL-4 and INF-gamma mRNA expressions were measured in Peyer's patch and spleen tissue at w10. RESULTS: The levels of total IgE and IgG1 were increased by age while the level of IgG2a was decreased. Chow-specific IgE and IgG2a responses were neglectable through out the whole experimental period (20-30 ng/ml or less). Chow-specific IgG1 levels were measured in the significant concentrations (200-300 ng/ml) but there was no age-dependent change through out the experiment. Con A stimulated-splenocyte proliferation indexes were variable according to the culture-durations and ages of mice. The higher proliferation indexes were observed in the wells receiving thymidine pulse at 48-hour culture, especially in the mice at w10. Con A stimulated IL-4 production in the 72-hour splenocyte culture supernatant was significantly increased at w8, and w10 while INF-gamma production increased only at w10. The changes in the production of IL-5, IL-12 and TGF-beta did not provide significant information in the present study. The ratio of IL-4/IFN-gamma mRNA expression was higher in Peyer's patch than in the spleen. CONCLUSION: The changes of B-cell and T-cell mediated immunologic parameters were complex and variable according to the age in naive C3H/HeJ mice under regular chow feeding conditions. For that reason, the information from the present study needs to be considered in the course of planning or analysing research/data using murine systems.

BACKGROUNDS: Patient counseling has been forced since June. 19, 2014. Prior to this, there was no study to try to standardize medication counseling to improve quality. PURPOSE: This study was to investigate satisfaction level and comprehension level between the pharmacist group and the patient group about standardized medication counseling sheet. METHODS: Questionnaires to assess standardized patient counseling sheet were posted at online survey software (Qualtrics) to pharmacists who worked at community pharmacy and patients who had visited community pharmacy before. RESULTS: Three hundred thirty five patients and three hundred nineteen pharmacists were responded to the questionnaire (Response rate: 72.9%). More than half of each group were satisfied with standardized medication counseling sheets 'for the general public', 'for the pregnant women and nursing mothers', 'for the chronic patient', and 'for the aged' and patient group were more satisfied than pharmacist group. Similarly, more than half of each group comprehended with the medication counseling sheets 'for the general public', 'for the pregnant women and nursing mothers', 'for the chronic patient', and 'for the aged'. Patient group tended to expect longer patient counseling time per one drug than pharmacist group. Also, the majority of both groups wanted to provide standardized medication counseling sheets constantly and extend for all drugs. CONCLUSION: Both groups were satisfied and comprehended standardized medication counseling sheets, and agreed to expand standardized medication counseling sheets to all drugs. So, it is necessary to build the standardized medication counseling of all drugs.
