Purpose: This study was done to evaluate the effectiveness of an education program for patients with asthma who use inhalers. Methods: The research design for this study was a non-equivalent control group quasi-experimental study. Participants in this study were 36 patients for the control group, and 43 patients for the experimental group. The experimental group participated in the education program. The control group received the usual care. Data were collected before and 1 month and 2 months after the program finished and were analyzed using the SPSS 12.0 program. Results: The experimental group had significantly higher scores of knowledge of inhalers, and inhalation technique compared to the control group. However, no significant differences were found between two groups for PEFR, asthma instability, and satisfaction with inhalers. Conclusion: According to the results, the education program was effective in improving knowledge of inhalers, and inhalation technique. Therefore, it is recommended that this education program be used in clinical practice as an effective nursing intervention for patients with asthma on inhalers.

Background : Asthma is considered to be an inflammatory disease characterized by airway hyperresponsiveness and pulmonary eosinophilia. Production of cytokines by bronchial epithelial cells may contribute to the local accumulation of inflammatory cells in patients with bronchial asthma. In many recent studies molecular biological methods have been used to investigate the role of cytokines in pathogenesis and new therapeutic targets of asthma. Objective : We aimed to identify the effects of Sochongryong-tang on Serum IL-4, IL-5, $IFN-{\gamma}$ in asthmatic patients. Material and Methods: The subjects consisted of 15 patients with asthma who had been treated with Sochongryong-tang for two weeks from February 2001 through June 2001. Sochongryong-tang is an herbal decoction which has traditionally been used as a therapeutic agent for asthma. Results : The serum IL-4 in asthmatic patients was increased significantly compared to the serum IL-4 in the normal control group. However, the serum IL-5, $IFN-{\gamma}$ in asthmatic patients showed no significant difference from the serum IL-5, $IFN-{\gamma}$ in the normal control group. The patients were treated with Sochongryong-tang for two weeks with no significant difference in the serum IL-4, IL-5, and $IFN-{\gamma}$. Conclusion : This study shows that the serum IL-4 may be a new therapeutic target of asthma. Further long-term studies must be made in a larger number of asthmatic patients.

Purpose: Synthesis of regulated on activation, normal T-cells expressed and secreted (RANTES) in the airway has previously been shown to be elevated after respiratory syncytial virus (RSV) infection. However, since few studies have examined whether RSV-infected asthma patients express a higher level of RANTES than do normal individuals, we used a murine model of asthma to address this question. Methods: We prepared Dermatophagoides farinae-sensitized mice as an asthma model, and then infected them with RSV and analyzed the changes in airway responsiveness and the cell populations and cytokine levels of bronchoalveolar lavage fluid. Results: RANTES synthesis increased in response to RSV infection in both control mice and in asthma model (D. farinae) mice. However, there was no significant difference in the amount of RANTES produced following RSV infection between control and D. farinae mice. RSV infection affected neither interferon-${\gamma}$ synthesis nor airway responsiveness in either control or D. farinae mice. Conclusion: RSV infection did not induce more RANTES in a murine model of asthma than in control mice.

The present study was made with the aim of finding out the Kamihaepyoijin-tang's effect on the allergic asthma using the Egg-White Implant(EWI) method model recommended by de Siqueira et al. Kamihaepyoijin-tang has widely been prescribed and used in Oriental Medicine for controlling and curing of cough, asthma, nasal obstruction. Previous studies have demonstrated that Kamihaepyoijin-tang had analgesic, anticonvulsive effects. But it is uncertain whether Kamihaepyoijin-tang could inhibit the allergic reaction of rats with experimentally induced allergic asthma using EWI method. With such aim. the respiratory patterns and eosinophil infiltration in the tracheal mucosa of the rats were mainly observed. The results were summerized as follows ; 1. The frequency of malformed respiratory patterns in Kamihaepyoijin-tang treated groups were decreased as compared with the control group. 2. The Ratio of malformed respiratory patterns in Kamihaepyoijin-tang treated groups were significantly decreased as compared with the control group(p<0.02). 3. The eosinophil infiltration in Kamihaepyoijin-tang treated groups were decreased as compared with the control group. 4. The eosinophil infiltration that inside of trachea tissue in Kamihaepyoijin-tang treated groups were significantly decreased as compared with the control group(p<0.05). Depending upon above results, it is considered that Kamihaepyoijin-tang has the inhibitory effects on the allergic asthma of rats and suggested that it could be used in relieving patients of the symptoms which are caused by allergic asthma.

Asthma is a chronic inflammatory disease of the airways characterized by varying and recurrent symptoms, reversible airway obstruction, and bronchospasm. In this paper, clinical important studies on asthma published between March 2021 and February 2022 were reviewed. A study on the relationship between asthma and chronic rhinosinusitis, bronchiectasis, and hormone replacement therapy was published. A journal on the usefulness of fractional exhaled nitric oxide for the prediction of severe acute exacerbation was also introduced. Studies on the effect of inhaler, one of the most important treatments for asthma, were published. Studies on the control of severe asthma continued. Phase 2 and 3 studies of new biologics were also published. As the coronavirus disease 2019 (COVID-19) pandemic has been prolonged, many studies have explored the prevalence and mortality of COVID-19 infection in asthma patients.

The aim of this study was to acquire information related to recognition of atopic dermatitis, asthma, and snack intake status among middle school students in the Seoul area. The survey was carried out by self-questionnaires on 535 students in the 2nd and 3rd grade (88 Patients: atopic dermatitis and asthma group and 428 Control: healthy group). All data were analyzed using SPSS (version 13.0) software. The results were as follows: Among patients, females (61.4%) had a significantly higher prevalence of symptoms than males (38.6%) (p<0.001). Body mass index was not significantly different between the patients and Control group. The most common source for obtaining information about atopic dermatitis and asthma was 'TV or radio' (38.4%), followed by 'family members or relatives' (27.3%) in patients, but 'Internet' (22.2%) was most common in the control group (p<0.05). Although awareness of atopic dermatitis and asthma was similarly low between the two groups, patients had a higher percentage of correct answers on atopic knowledge (p<0.05). However, there was no significant difference in knowledge of asthma between the two groups. Frequency of snack intake was significantly lower in patients (p<0.05), and consumption of sundae, fried food, liquefied fermented milk, hamburger, pizza, and french fries was also significantly lower (p<0.05). The reason of selecting snacks was mainly 'taste' in both groups. In conclusion, education regarding atopic knowledge and appropriate snack selection is necessary for students with atopic dermatitis or asthma.

Asthma is a chronic inflammatory disease characterized by airway hyperresponsiveness (AHR) and reversible airway obstruction. Methacholine (MCh) is widely used in broncho-provocation test to evaluate airway resistance. For experimental investigation, ovalbumin-induced sensitization is frequently used in rodents (Ova-asthma). However, albeit the inflammatory histology and AHR in vivo, it remains unclear whether the MCh sensitivity of airway smooth muscle isolated from Ova-asthma is persistently changed. In this study, the contractions of airways in precision-cut lung slices (PCLS) from control, Ova-asthma, and IL-13 overexpressed transgenic mice (IL-13TG) were compared by analyzing the airway lumen space (AW). The airway resistance in vivo was measured using plethysmograph. AHR and increased inflammatory cells in BAL fluid were confirmed in Ova-asthma and IL-13TG mice. In the PCLS from all three groups, MCh concentration-dependent narrowing of airway lumen (${\Delta}AW$) was observed. In contrast to the AHR in vivo, the $EC_{50}$ of MCh for ${\Delta}AW$ from Ova-asthma and IL-13TG were not different from control, indicating unchanged sensitivity to MCh. Although the AW recovery upon MCh-washout showed sluggish tendency in Ova-asthma, the change was also statistically insignificant. Membrane depolarization-induced ${\Delta}AW$ by 60 mM $K^+$ (60K-contraction) was larger in IL-13TG than control, whereas 60K-contraction of Ova-asthma was unaffected. Furthermore, serotonin-induced ${\Delta}AW$ of Ova-asthma was smaller than control and IL-13TG. Taken together, the AHR in Ova-asthma and IL-13TG are not reflected in the contractility of isolated airways from PCLS. The AHR of the model animals seems to require intrinsic agonists or inflammatory microenvironment that is washable during tissue preparation.

Objective: This study was eanied out to investigate the effects of Raphani Semen on immuno-response in the mouse model of allergic asthma. Methods: In this study, BALB/C mice were divided into 6 groups: Normal (Non-treated group), Control (Group with not treated after allergic sensitization and induction by ovalbumin), Treat I (Group with the oral administration of saline after allergic sensitization and induction by ovalbumin), Treat n (Allergic asthma group treated with acupuncture (BL 13)), Treat III (Allergic asthma group treated with the oral administration of Raphani Semen) and Treat lV (Allergic asthma group treated with the herbal-acupuncture of Raphani Semen (BL 13)). The effect on cytokine was assessed by measuring cytokine (lL-2, IL-4, IL-5, IL-10, IL-12, IFN-r) in bronchoalveoar lavage fluid(ELISA). ResuJts : The results obtained as follows: 1. The production of Interleukin-2 was decreased significantly in Treat I group, Treat n group and Treat IV group as compared with Control group. 2. The production of Interleukin-4 was decreased significantly in Treat I group, Treat II group and Treat IV group as compared with Control group. Among them. the production of Interleukin-4 was decreased remarkably in Treat IV group as compared with other groups. 3. The production of Interleukin-5 was decreased significantly in Treat I group and Treat IV group as compared with Control group. 4. The production of Interleukin-10 was decreased significantly in Treat I group and Treat III group as compared with Control group. 5. The production of Interleukin-12 was all decreased significantly in Treat I group, Treat n group, Treat m group and Treat IV group as compared with Control group. 6. The production of Intelferon- showed no significant changes in Treat I group, Treat n group. Treat m group and Treat Ⅳ group as compared with Control group. Conclusion: These results show that the production of Interleukin-4, 5 was decreased significantly in aJlergic asthma group treated with the herbal-acupuncture of Raph Semen (BL 13), It is known that inactivity of Th2 cell constrained the revelation and controlled hypersenstive action. As to this mechanism, it is suggested that the herbal-acupuncture of Raphani Semen(BL 13) constrained the revelation of allergic asthma.
