It this study, basic data were obtained for the treatment of industrial waste water which includes aromatic compounds. Substrate concentrations used were 100ppm, 500ppm, and 1,000pprn and initial pH's were pH6, pH7, and pH8 in order to obtain the optimum conditions for treating benzoate, m-toluate, and phenol by Pseudomonas putida(KCTC 1644). Durations were 20hrs for 100ppm, 40hrs for 500ppm, and 60hrs for 1,000ppm before the static growth of Pseudomonas putida. 100% of 100ppm benzoate(0.31g cell/1) was biodegraded at pH6, pH7, and pH8 before 20hrs, 52.8% of 500ppm at pH8 in 40hrs, and 27.9% of 1,000ppm at pH8 in 60hrs. The best initial pH was pH8 for the biodegradation and the growth of Pseudomonas putida in benzoate medium. For m-toluate, the best initial pH was also pH8. At this pH, 40.6% of 10Dppm(0.31 cell/1), 21.9% of 500ppm, and 14.1% of 1,000ppm m-toluate were biodegraded respectively in limited time. But for phenol, the best initial pH was pH7. At this point, 9.8% of 100ppm(0.218 cell/1), 7.1% of 500ppm, and 4.7% of 1,000ppm phenol were biodegraded respectively. Therefore, the best carbon source in this experiment was benzoate. Pseudomonas putida was also able to biodegrade m-cresol, p-hydroxybenzoic acid, and benzaldehyde.

내시경적 역행성 담췌관조영술 후 발생한 급성췌장염의 발생인자로 여러 가지 인자들이 관여하지만 특히 담췌관조영술 시행 후 과도한 췌선방 조영화에 의한 중증의 췌장염 증례를 경험하였기에 보고하는 바이다 Endoscopic retrograde cholangiopancreatography (ERCP) has been considered as a valuable tool for the diagnosis and management of disease of the pancreas and biliary tree. Post-ERCP pancreatitis is the most frequent and clinically significant complication following ERCP. But a few complication associated with this procedure are unforeseeable. Specially, acinarization as a result of a careless cooperation between operator and assistant may be influenced in complications of ERCP. Severe post-ERCP pancreatitis is rare complication, and its prognosis will be poor. Therefore, careful process and good relationship between operator and assistant in ERCP may be prevented this complication, but is not clear. Neglect of acinarization may be resulted in more aggravation of pancreatitis. We have cared for one patient with severe post-ERCP pancreatitis with pseudocyst after water-soluble contrast media spreading into the acini (acinarization) via ERCP in resolving phase idiopathic pancreatitis.

Background and objectives : A disparity between clinical and urodynamic findings is commonly found and its application to the clinical management of neurogenic bladder is pratically as well embrassing as it reading. We investigated urodynamic study for the diagnosis and management of neurogenic bladder. Materials and methods : From July 1997 to June 2001, total of 83 patients of neurogenic bladder were evaluated by urodynamic study. Results : urodynamically, there were 20 cases(24%) showing detrusor hyperreflexia with detrusor external sphincter dyssynergia(DESD), 12 cases(15%) detrusor areflexia with low compliance. A disparity between the clinical and urodynamic assessment was noted in 26 cases(31%), clinically severe symptom with complication was particularily common in detrusor hyperreflexia with DESD, detrusor areflexia with low compliance and catheter indwelling patients. Conclusion : In neurogenic bladder, clinically symptom with complication was particularly common in detrusor hyperreflexia with DESD, detrusor areflexia with low compliance and catheter indwelling patients.

Jang, Seog-Ki,Kim, Sang-Wook The Korean Society of Mycology 2015 Mycobiology Vol.43 No.2

We collected and identified 5,721 ectomycorrhizal fruiting bodies (EcM) from Naejangsan National Park from June 2004 to 2013, belonging to 1 phylum, 1 class, 6 orders, 19 families, 40 genera, and 196 species. Of these, 2,249 individuals were identified as 89 species belonging to 11 genera in 7 families in the Agaricales; 1,511 were identified as 43 species belonging to 2 genera in 1 family in the Russulales; 1,132 were identified as 50 species belonging to 21 genera in 6 families in the Boletales; 793 were identified as 8 species belonging to 3 genera in 2 families in the Cantharellales; 29 were identified as 3 species belonging to 2 genera in 2 families in the Thelephorales; and 7 were identified as 3 species belonging to 1 genus in 1 family in the Gomphales. Thus, most of the EcMs identified belonged to the following 3 orders: Agaricales, Russulales, and Boletales. Russulaceae were most common (43 species), followed by Boletaceae (39 species), and Amanitaceae (27 species); most individuals were Russulaceae (1,511), followed by Hydnagiaceae (1,071) and Boletaceae (804). The monthly distribution showed that the greatest number of individuals and species of EcM, including the dominant ones, occur around July~September at an elevation of 200~299 m, diminishing markedly above 600 m. The greatest number of individuals and species, including the dominant ones, were collected in the period with average temperatures $25.0{\sim}26.9^{\circ}C$, lows of $21.0{\sim}22.9^{\circ}C$, and highs of $30.0{\sim}31.9^{\circ}C$, relative humidity > 76%, and rainfall > 400 mm.
