PURPOSE: Patients with diabetic cystopathy ultimately undergo morphometric and functional changes in their bladder. Therefore, various voiding symptoms such as frequency, nocturia, urgency, hesitancy, retention and weak stream were evaluated. Irritative symptoms usually develop in cases where the prevalence period of diabetes mellitus (DM) is short, and the obstructive symptoms develop in the opposite case. Improving the voiding symptoms might differ according to prevalence period. Therefore, the therapeutic efficacy of the treatment was compared. MATERIALS AND METHODS: One hundred ten patients were divided into three groups according to how long they had suffered from DM, and were treated with medical therapy over a 4 week period: group A (<5yrs), group B (5-10yrs), group C (>10yrs). The patients were asked to write their subjective symptoms in a voiding diary and a urodynamic study was undertaken. RESULTS: After medical therapy, the frequency, nocturia and urgency in group A had improved to 72%, 77% and 88% respectively (p<0.05). The frequency, nocturia, urgency, hesitancy, retention and weak stream in group B had improved to 51%, 57%, 66%, 59%, 69% and 61% respectively (p<0.05), and in group C these symptoms had improved to 15%, 12%, 10%, 17%, 12% and 8% respectively (p>0.05). In a urodynamic study of group B, the maximum detrusor pressure had increased from 20.3+/-6.7cmH2O to 53.5+/-8.1cmH2O and the post void residuals decreased from 62.3+/-36.4ml to 21.2+/-17.1ml (p<0.05). In addition, there were little improvements in the maximum bladder capacity, the first sensation and compliance (p>0.05). In group C, there was little improvement in the urodynamic study (p>0.05). CONCLUSIONS: The medical therapeutic efficacy for these patients reduces as the DM revalence period is longer.

We experienced chronic relapsing central corneal ulcer and chronic conjunctivitis with mucoid discharge. Both patients were transfered to our hospital because of no improvement with long term treatment of broad spectrum antibiotics topically and systemically Specimens from corneal scraping and conjunctival mucoid discharge were examined with calcofluor white staining method. We could find a narrow rim of light green colored cystic wall and orange red colored cytoplasm in dark field fluorescent microscopy in both cases, and those were diagnosed as Acnthamoebic cyst by pathologist. We couldn't find any report about ocular Aanthamoeba infections in Korea. To our knowledge, this is the first case report about ocular Acanthamoebic infections in Korea.

Blood pressures and heart rates were recorded with Twin-Viso (Sanborn, USA) for comparative estimations of cardiovascular responses by injection of intravenous anesthetic agents-2.5% solution of Pentothal Sodium (Abbott Laboratory, USA) and Thiotal (Samsung Pharmaceutical Co., ROK) mongrel dogs. Dogs were evaluated the hepatic function by biochemical studies of blood such as total protein, albumin, total bilirubin, direct bilirubin, thymol turbidity test, alkaline phosphatase, serum glutamic oxaloacetic transaminase (SGOT) and serum glutamic pyruvic transaminase (SGOT). Liver biopsies were performed in dogs for identifications of hepatic darnages by injection of the above barbiturates, The following results were observed: 1) It was observed the remarkable negative inotropic effect in myocardium of the mongrel dogs intravenously injected with 20 mg/kg of the above barbiturates for three minutes (Table 7, Fig. 8) 2) It was noted slight negative inotropic effect in mongrel dogs intravenously injected with 10 mg/ kg of the above barbiturates for thirty seconds (Table 8, Fig. 8). 3) It was more shorter recovery time from negative inotropic effects in mongrel dogs injected with Thiotal than in the dogs injected with Pentothal Sodium. 4) It was noted no significant changes in pathological studies of Hematoxylin-Eosin stained liver specimen and liver function studies of the blood by biochemical analysis in mongrel dogs intravenously injected everyday with 10 mg/kg of the above barbiturates. 5) It was noted slight changes in mongrel dogs injected with 20 mg/kg of the above barbiturates on TTT, Alkaline Phosphatase, SGOT and SGPT as biochemical analysis in comparing with controI values. These values, however, were not concided with the pathological findings of HematoxyIin-Eosin stained liver biopsy specimen. The facts explain to be inquired into further investigations in the pathological and biochemical aspect.

PURPOSE: To evaluate a recently developed technique to place a medium-duration(weeks to months) central venous access. MATERIALS AND METHODS: Within three-year period, 635 patients were referred to interventional radiology suite for placement of peripherally inserted central catheter(PlCC). Contrast medium was injected into the peripheral intravenous line and a puncture was made into the opacified vein near the junction of the middle and upper thirds of the upper arm, either the brachial or basilic vein under fluoroscopic guidance. A 5.5-French peel-away sheath was inserted into the vein and a 5- French silicone catheter was introduced with its distal tip to the junction of the right atrium and superior vena cava. RESULTS: Catheter placement was successful in all patients unless there was a central venous obstruction. Catheters were maintained from 2 days to 5 months with a mean of 3 weeks. Complications included infection requiring removal of the PICC in 16 patients(2.5%), acute thrombosis of the subclavian vein in 3(0.5%). Occluded catheters in 4 patients were easily cleared with urokinase in place. CONCLUSION: The PICC system is an excellent option for medium-duration cen- tral venous access. Patients were able to carry on normal activities with the catheters in place.

A central vacuum scavenger modified by the authors, was used to control the atmospheric contamination of the operating room by anesthetic gases and vapours. Air pollution was monitored by measuring the concentrations of halothane vapour in the air of the operating room with the gas chromatograph. Under endotrachal intubation, the semi-colsed circle absorber system was used for anesthetic administration and maintained with 0.8~1.2% Halothane. Total gas flow rates were 4 liter/min with 50% oxygen in nitrous oxide for daily work. Air sampling was taken early in the morning at 10cm high from the floor before anesthesia. After daily work, they were also done at 10cm, 120cm, and 140cm high from the floor and at the corridor of the operating room. We investigated the differences of halothane concentration according to each sits by the changing central vacuum pressure. Results are followings: The atmospheric halothane concentration of the operating room before anesthesia were 0.27+/-0.12, 0.22+/-0.11 and 0.15+/-0.06 ppm.The atmospheric halothane concentration of the operating room after daily work were 7.94 +/- 1.30 ppm without the active central vacuum pressure.The atmospheric halothane concentration of the operating room after daily work were 1.41 +/-0.48ppm of 20mmHg of central vacuum pressure.The tmospheric halothane concentration of the operating room after daily work were 0.49+/-0.18ppm of 40mmHg of central vacuum pressure. The atmospheric halothane concentrations at the corridor of the operating room after daily work were 1.09+/-0.19, 0.77+/-0.11n and 0.36+/-0.17ppm when each vacuum pressure was 0mmHg, 20mmHg and 40mmHg. A significant reduction (p<0.01) in atmospheric halothane concentration of the operation room was obtained by the use of the central vacuum pressure with the scavenger. The higher the vacuum pressure, the greater reduction of the operating room air pollution was observed.

The anesthetic experience in 20 years was evaluated by statistically analyzing the total of 17,595 cases which were performed at S.N.U.H. from 1960 through 1979 according to age, sex, anesthetic agents and methods. To simplify the analysis, the authors selected the anesthetic cases of 1960, 1965, 1970, 1975, and 1978. The results were as follows: 1) General anesthesia has been used with increasing frequencies and local anesthesia with decreasing frequencies during the period. 2) More than half of the totaI cases were performed for the patients in their second or third decades. 3) General surgery cases were the majority of the total. 4) The usage of halothane has been increased ever since its introduction into clinical anesthesia in this hospital. 5) For intravenous induction, thiopental has been used as the main agent, and succinylcholine and pancuronium as the major muscle relaxants since 1975. 6) For anesthetic technique, semiclosed circle absorption system has been employed in almost all cases, and non-rebreathing system has been used recently with increasing frequencies in pediatric anesthesia.

OBJECTIVES: The early detection of ectopic tubal pregnancy in unruptured state is increased as the transvaginal sonography and sensitive serum hCG test are available. For this unruptured tubal pregnancy, the medical treatment using methotrexate via various routes and dosage is being tried. Our study was to evaluate the efficacy of single systemic injection of methotrexate in the treatment of unruptured tubal pregnancies. Material and METHODS: From the January 1997 to July 1999, of 152 ectopic pregnancy patients, 22 patients who were diagnosed as unruptured tubal pregnancies were treated with single-dose systemic methotrexate injection (50 mg/m2/IM). Exclusion criteria were unstable vital signs with hemoperitoneum, adnexal mass > 5-6 cm. Serum hCG titers were checked before injection and 4, 7 day after injection. If serum hCG titer declined more than 15% on 7 day after injection compared with titer on 4 day, the weekly hCG titer was followed until it was <10 mIU/ml .If the hCG titer did not decline more than 15 %, a second dose was given. If hCG titer was not decreased or vital signs became unstable after 1-2 injections, the treatment was considered failure and surgery was done. RESULTS: 18 cases (82%) of 22 were successfully treated with single-dose methotrexate. The mean size of ectopic mass and initial serum hCG titers were 2.7+/-1.3 cm (range, 1.5-5.4 cm) and 3,298+/-1,007 mIU/ml (range, 132-12,239), respectively. Of 22, 6 cases (28%) needed second dose of methotrexate. The mean time to resolution of serum beta-hCG titer was 27.5+/-13.6 days (range, 8-53 days). Elevation of liver enzyme did not occurred in all cases during treatment. Initial hCG titer was more important prognostic factor than ectopic mass size for successful medical treatment. CONCLUSION: Single-dose methotrexate appears to be an effective medical treatment for the unruptured tubal pregnancy. However, patients selection using strict criteria is needed to increase its success rate.
