Objectives & Methods : In order to evaluate the in vitro synergic effects or Eunkyo-san which is a traditional poly-herbal formula that has been used in the treatment of respiratory diseases in oriental medicine, and quinolone antibiotics, rufloxacin (RUFX) and iprofloxacin(CPFX), experimentation was designed to determine minimal inhibitory concentration(MIC), $MIC_{50}\;and\;MIC_{90}$ of single use of quinolones and concomitant treatment with Eunkyo-san against 5 strains of aerobic gram negative bacteria, Escherichia coli, Klebsiella peumoniae, Hemophilus influenzae, Citrobacter freundii and Pseudomonas aeruginosae. Result : In the case of aerobic gram negative bacteria, the MIC, $MIC_{50}\;and\;MIC_{90}$ against Klebsiella peumoniae and Citrobacter freundii significantly decreased in concomitant-treated groups with Eunkyo-san compared to those of single-treated groups of RUFX and CPFX, respectively. However, no significant changes were demonstrated against Echerichia coli, Hemophilus influenzae and Pseudomonas aeruginosae. Conclusion : According to these results, concomitant use of Eunkyo-san against some strains of aerobic gram-negative bacteria dramatically increases in vitro antibacterial activity of RUFX and CPFX, and the increase and selectivity of antibacterial activities against these strains is attributable to Eunkyo-san, and not RUFX or CPFX activity.

Objectives Acute Bronchiolitis is an acute lower respiratory disease that the most often seen in children. The purpose of this study is to report three cases of acute Bronchiolitis children treated by oriental medicine. Methods The subjects are children diagnosed as having an acute Bronchiolitis. We treated three children with herbal medicine(Eunkyosan-gamibang) Results After treatment, the symptoms(cough, dyspnea, wheezing) of Acute Bronchiolitis were relieved. Conclusion This study shows that oriental medicine can be an effective treatment for Acute Bronchiolitis. Further study is needed with more cases of treatment.

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.

Yinqiao San is the medicine for the outer part disease of the human body. In ${\ulcorner}$Wenbingtiobian${\lrcorner}$, this medicine is the most useful when it is used within short time after the starting boiling it. In this study, the volatile ingredients of the Yinqiao San were observed by GC and compared with each other in time scale. Most of the ingredients were observed about 5 min after the starting boiling it, after10 min., the GC peaks were smaller and smaller, and after 2 hours and 30 min. the GC peaks were almost gone. It is confirmed that was written about the Yinqiao San in ${\ulcorner}$Wenbingtiobian${\lrcorner}$.
