A 40-years-old woman was admitted to this hospital with flank pain and high grade fever for 2 weeks. As a matter of her past history, extracorporeal shock wave lithotripsy (ESWL) was performed for treatment of renal stones 5 years ago. Her abdominal CT findings were hydronephrosis with pyonephrosis and renal stones. Antibiotics administered for 5 days had no effects on her symptom improvement. A right ureteral stricture was noticed by ultrasonography follow up. We inserted double J stent and continued antibiotics therapy for 10 days, and then her fever was disappeared and flank pain was improved. ESWL is one of the most important treatment of renal and ureteral stone. However, its complications should not be negligible including bleeding, pain, ureteral obstruction, infection and so on. Complications of ESWL can be divided into acute and chronic courses. When we treat pyelonephritis patient with past history of ESWL, possibility of ureteral stricture must also be considered. In this study we report a case of pyelonephritis caused by ureteral stricture, possibly as a chronic complication of ESWL performed 5 years earlier

Pseudomembranous colitis (PMC) is a disease caused by Clostridium difficile proliferation. The causative drugs are clindamycin, third-generation cephalosporins, flouroquinolone and so on. Rifampicin has been reported as a cause of PMC in the 1980s, and the frequency of PMC is increasing because rifampicin is a first line drug for anti-tuberculosis therapy. Two patients were recently admitted to our hospital due to watery diarrhea for 1 month and they were diagnosed with PMC by sigmoidoscopy. Their onset age were 74, 72 years old and latent period of symptoms were 60, 129 days, respectively. In one case, the patient displayed coexisting hypertension and diabetes. The clinical symptoms improved after discontinuing the rifampicin and then administering oral metronidazole. We report here on two cases presumed to be rifampicin-induced PMC.

This study was carried out to evaluate performance of sewage treatment facility in rural area. Average effluent concentration was 7.6㎎/1 BOD. 10.3㎎/1 COD, 4.7㎎/1 SS, 19.140㎎/1 TN, and 1,631㎎/1 TP, within discharge quality standard. The removal efficiency rate of BOD, COD and SS was good as 89.8%. 78.5% and 90.1%, respectively. But that of TN, TP was very low as 25.0% and 31.4% respectvely. Average sewage flow rate was investigated by about 1.1㎥/d per household, 398ℓ pcd. In rainfall period, the removal efficiency rate of BOD. TN and TP was very low as 15%, 22% and 28%, respectively because of inflow and infiltration into sewer. In flowing concentration of sewage was diluted as rain is inserted into sewer and submerged facility was not operated at normal condition. Therefore it is required that the sewer will have to repair and hydraulic design for facility will have to be check. So it is necessary to support systematical, administrative measures for responsible management.

Background : The cun measurement System, an essential and convenient method in locating acupoints, has been widely used in the practice of acupuncture. However, traditional cun measurement has been criticized for its lack of reliability. Objectives : The purposes of this study are to determine if one cun measured by the directional methods have a consistency with that of proportional methods and to investigate which factors are related with these differences, especially in forearm. Methods : The distance between the elbow crease and the wrist crease of forearm was compared to a reference value of one cun obtained by the directional method. In this method, one cun is one third of the distance between index finger and Small finger of a subject, measured at proximal interphalangeal joint. In addition, to investigate the factors influencing the differences between these two methods, we measured the height and body weight and calculated body mass index (BMI). Finally we analyzed the factors correlated with these lengths by linear regression test. Results : The results showed that one cun obtained by the directional methods were significantly different from one cun by the proportional methods in forearm. It was demonstrated that the length acquired with the directional method was more correlated with body weight and body mass index, while the length obtained by the proportional method was more correlated with the height.

<P>We developed a fluorescent pH probe (1) capable of two-photon excitation and far-visible-emission based on FRET, composed of naphthalimide-piperazine-rhodamine. It exhibited a pH-dependent reversible and fast ratiometric fluorescence change in the rhodamine emission. Probe 1 was applied to image the pH perturbations of mitochondria in living cells and tissues.</P>

The metacarpal shaft fracture has been reported as a stable fracture relatively, but operative treatment is indicated when there happens reduction lass, or is in need of early exercise. Intramedullary K-wire fixation has been used for unstable transverse or long oblique diaphyseal fracture of the metacarpal bone. The fracture site is not opened and the K-wires are introduced under X-ray control. The techniques can stablize the fracture site and allow immediate exercise postoperatively. We experienced 9 cases of 4th metacarpal shaft fracture treated by percutaneous intramedullary K-wire fixation with modified technique.. The K-wire was used one or two each metacarpal fracture. The types of fracture were 4cases of transverse, 3 of oblique, 2 of comminuted. The average clinical union period were 5 weeks. There were not severe complications in all cases.
