Objective: The purpose of this study was to develop a standard tool for identifying idiopathic pulmonary fibrosis patterns. Methods: Textbooks, published literature, and references with comments on patterns were reviewed. Using the Delphi method, we determined pattern identification based on the advice of a committee consisting of 11 Korean respiratory internal medicine professors. Results: Four pattern identifications were selected by the Delphi method: qi difficiency (氣虛), yin difficiency (陰虛), phlegm dampness (痰飮), blood stasis (瘀血). The tool was developed in a question-and-answer format containing 38 questions. Conclusions: An IPF pattern identification tool that can analyze IPF patterns for standardized diagnostics was developed with the consent of experts. Further research is needed on its reliability.

Recently a major goal in asthma therapy is to reduce or prevent the inflammatory response of airway. Eosinophilic accumulation in the tissue is a prominent feature of allergic diseases including asthma. Production of chemokines by bronchial epithelial cells may contribute to the allergic inflammation by recruiting eosinophils. In this study we evaluated the inhibitory effect of Gamichungsangbohatang (GMCSBHT), used traditionally in treating asthma, on secretion of chemokines for eosinophils in human A549 epithelial cells. Chemokines such as eotaxin, RANTES, IL-8 were inhibited in a dose-dependent manner, but IL-16 showed no inhibition by GMCSBHT. These findings indicate that GMCSBHT might be a therapeutic value in treating asthma by suppression of chemokines secretion associated with local accumulation of eosinophils.

Purpose : The purpose of this study was to investigate whether the respiratory cycle and posture can modulate the autonomic nervous system. Methods : Thirty-two healthy men and women, aged 20-30 years, were enrolled in this study. We conducted 2-second and 6-second respiratory cycle with the subjects in standing, sitting, and supine positions, respectively. Their heart rate variability was measured in each position for both cycle lengths. Results : The low frequency/high frequency (LF/HF) ratio is derived from heart rate variability. In the 2-second respiratory cycles, the LF/HF ratios were highest in standing, sitting, and supine position in descending order. There was a significant difference in heart rate between standing and sitting positions (P<.005). In addition, there was a significant difference in heart rate between standing and supine position (P<.000). In the 6-second respiratory cycles, the LF/HF ratios were again highest in a standing, sitting, and supine position in descending order. However, posture was not found to make a significant difference in this case. Conclusion : Respiratory cycle and posture effectively modulated the autonomic nervous system. Further studies of the clinical application of these results should be conducted.

In order to evaluate the in vivo synergic effect of Eunkyo-san with quinolone antibiotics, rufloxacin (RUFX), the viable bacterial numbers and histopathological changes were monitored after experimental respiratory infection with Klebsiella peumoniae NCTC 9632. The obtained results were as follows : In RUFX group, the viable bacterial numbers were significantly decreased compared to those of control group and these were more dramatically decreased compared to those of single treatment with RUFX, respectively in concomitant treated groups with Eunkyo-san. In control group, severe infiltration of inflammatory cells, hemorrhage and hypertrophy of alveolar linings were demonstrated at microscopical levels. However, these abnormal histopathological changes were significantly decreased compared to those of control group in RUFX group, and these were more dramatically decreased compared to those of single treatment with RUFX, respectively in concomitant treated groups with Eunkyo-san. In RUFX group, the LSA% (luminal surface of alveolar%) were significantly increased compared to those of control group and these were more dramatically decreased compared to those of single treatment with RUFX, respectively in concomitant treated groups with Eunkyo-san. According to these results, it is considered that in vivo antibacterial activity of RUFX group was dramatically increased by concomitant use of Eunkyo-san against K. pneumoniae NCTC 9632 infection of respiratory tract.

Objectives : Ryodoraku, which is a physiological function test using electric current, is closely related to skin sympathetic tone. Pulse analysis is known to reflect cardiovascular reactivity. Refer to the previous researches Ryodoraku and pulse analysis have value as tools for diagnosing respiratory diseases. In this study we examined the diagnostic values of Ryodoraku and pulse analysis for respiratory disease patients. Methods : For this study. we conducted Ryodoraku and pulse analysis on 114 people, including 83 respiratory disease outpatients and 31 volunteers who did not have any respiratory symptoms or disease history. The respiratory patients were divided into three subgroups according to their symptoms: rhinorrhea group, cough-sputum group and wheezing-dyspnea group. Then we compared the disease groups with the control group. Results : When all experimental groups were compared with the control group, mean Ryodoraku was significantly lower. Mean H2, mean H3 and mean H6 were significantly lower in the rhinorrhea group (P<0.05), all the test results of Ryodoraku were evidently lower in the cough-sputum group (P<0.01), and most results of Ryodoraku were evidently lower in the wheezing-dyspnea group except H1 (P<0.01). Compared with the control group on pulse analysis, mean YP+/YP- was significantly lower in the wheezing-dyspnea group (P<0.05). Conclusion : Ryodoraku and pulse analysis were found to have a high value as quantitative diagnosis tools reflecting individuals' weakness and firmness. Nevertheless, more research is needed to find the further values.

목 적: 본원에서 시행하고 있는 호흡동조 방사선치료(Respiratory Gated Radiation Therapy, RGRT)는 RPM (Real-time Position Management) Respiratory Gating System (version 1.7.5, Varian, USA)을 이용하여 실시하고 있다. 본 연구는 호흡변화에 따른 방사선치료의 정확성을 분석하고 평가하고자 한다. 대상 및 방법: 움직임을 임의로 조정할 수 있는 구동 팬텀(Motion Phantom)인 QUASAR Programmable Respiratory Motion Phantom (Moudus Medical Device Inc. CANADA)을 이용하였다. 폐암과 간암 환자 50명의 호흡을 분석하여 호흡의 변화를 관찰한 결과를 기준으로 주기 3초, 진폭 1.5 cm인 총 60초간의 기준호흡에서 매번 기저호흡(Baseline)을 기울기를 갖고 점진적으로 내려가는 경우와, 간헐적으로 기준 기저호흡 보다 더 내려가는 경우의 호흡 모양을 만들어 본원에서 사용되고 있는 Phase gating, 보통 30~70% gating 치료 방법과 동일하게 방사선을 조사하였다. 결 과: 점진적으로 매번 기저호흡이 0.01 cm, 0.03 cm, 0.05 cm씩 내려가는 호흡의 경우 모든 조건에서 방사선이 조사되었다. 간헐적으로 기저호흡이 0.2 cm, 0.4 cm, 0.6 cm, 0.8 cm 내려가는 경우도 모든 조건에서 방사선이 조사되어 RPM Respiratory Gating System에서 Phase gating 방식은 기저호흡 변화에 대하여 방사선이 모두 조사되었다. 결 론: 최적의 방사선치료를 위해 종양의 움직임을 고려하여 시행하는 호흡동조 방사선치료에서 RPM Respiratory Gating System의 Phase gating 방식은 본 연구에서와 같이 기저호흡의 변화가 호흡동조에 정확히 반영되지 않음을 알 수 있었다. 이에 호흡동조 방사선치료에는 무엇보다 환자의 호흡 관찰이 중요하다고 사료되며 호흡의 변화가 관찰되었다면 즉시 방사선치료를 멈추고 호흡을 관찰한 후 변화된 호흡상태에서 투시를 시행하여 치료부위를 다시 확인한 후에 치료를 재개하여야 한다고 사료된다.

Pulmonary surfactant is a lipoprotein complex composed primarily of phospholipid and lung specific apoproteins that reduces surface tension in the alveolus and maintains alveolar stability at low lung volume. Adult respiratory distress syndrome still carries a very high morbidity and mortality. The surfactant system is vital to the maintenance of proper lung function, any type of surfactant deficiency, whether primary or secondary, will contribute significantly to the development of pulmonary pathophysiology. Various mechanisms in adult respiratory distress syndrome may be responsible for such alterations in the surfactant system. Surfactant replacement is now an established treatment for neonatal respiratory distress syndrome, reducing both incidence of complications and mortality. With the current knowledge of surfactant physiology and the pathophysiology of the adult respiratory distress syndrome exogenous surfactant treatment or stimulation of endogenous surfactant synthesis and secretion will prove to be beneficial in preventing and treating the adult respiratory distress syndrome. The study of clinical surfactant therapy for adult respiratory distress syndrome is just beginnig and this can be viewed as an area with exciting potential. As soon as surfactant preparations become more widely available trials should begin to define the role of surfactant treatment in the adult respiratory distress syndrome as an adjunct to available treatment techniques.

Objective: In this study, a questionnaire survey was conducted for doctors and patients to obtain basic data necessary for the development of an integrated medical system for idiopathic pulmonary fibrosis (IPF). Methods: Questionnaires were developed separately for doctors and patients through an expert group meeting. The survey subjects were recruited online and offline, and finally, responses from 231 doctors and 59 patients were used for statistical analysis. Results: The most important parts in the treatment of IPF for both doctors and patients were the "improvement of respiratory symptoms," "improvement of quality of life," and "prevention of disease progression." Antifibrotic agents were prescribed at a high rate, and 100% of the specialists in Western medicine (WM) and 45.8% of patients reported experiencing side effects. As for the additional payment costs that patients considered as affordable for an integrated medical system, "under 50,000 won (about 38$)" was reported the most in both doctor and patient groups. With regard to the reasons for their reluctance to recommend an integrated medical system for IPF, specialists in WM responded highly to "uncertain evidence for treatment effectiveness." Regarding complementary and alternative medicine therapies that can be beneficial in patients with IPF, "lifestyle management," "diet management," "herb," "relaxation therapy," and "psychotherapy" were ranked high in both doctor and patient groups. Conclusions: In this study, a questionnaire survey on IPF was conducted to review actual treatment status, analyze shortcomings, and identify considerations for the development of an integrated medical system for IPF in the future.
