Recently it has been stated that animals without ischemic arrhythmia would be at almost no risk for reperfusion ventricular fibrillation(VF) in contrast to animals with ischemic arrhythmias. In order to observe the differences of ararrhythmias characteristics between ischemic and reperfusion period, and correlationship between occlusion and reperfusion arrhythmias, the left anterior descending(LAD) coronary artery was occluded for 20 minutes and reperfused for 10 minutes in 24 anesthetized cats. The results were as follows; 1) After ligation of LAD coronary artery, the R wave, S-T segment and T wave of epicardial EKG were elevated to reach maximum level at 5-10 minutes. 2) During reperfusion, the changes of R wave, S-T segment, and T wave of epicardial EKG were not significant. 3) The incidence of arrhythmias at early phase and late phase of occlusion period were 41.6% and 100% respectively. The ischemic arrhythmia score was 2.38+/-1.61 and incidence of ventricular tachycardia(VT) was 66% 4) The incidence of VT and VF during reperfusion was 100% and 62.5% respectively. The reperfusion arrhythmia score was 5.88+/-1.72. 5) The two morphologies of ventricular arrhythmias were observed at occluson and reperfusion period. 6) The disparities between occlusion and reperfusion arrhythmias were observed. 7) The cats with shorter R-R internal and/or lower systolic left ventricualr pressure had the higher incidence of VF. In summary, although the morphology of occlusion ventricular arrhythmias was similar to that of reperfusion ventricular arrhythmias, the lack of correlation between reperfusion VF and ischemic arrhythmias was observed. So we suggest that further studies which provide the different mechanisms involved in occlusion and reperfusion arrhythmias were needed.

Endobronchial tuberculosis is frequently associated with lymphadenopathy, bronchial stenosis, atelectasis which needs to be differentiated with other pulmonary disease. Authors are presenting 25 cases of endobronchial tuberculosis which were confirmed boy bronchoscopic biopsy and AFB smear and/or culture. The study was done on patients who visited Yeungnam University Hospital from May 1983 to July 1985. The following results were obtained: 1. Of the 25 cases, 8 cases were male and 17 cased were female (male:female=1:2). 32 percent of the cases was older than 60 years of age. 2. Abnormal findings on chest x-ray were seen on 22 cases of 25 cases (88%) and its most predilective site was right upper lobe (24%). 3. Symptoms were coughing (56%), hemoptysis, hoarseness, chest pain, dyspnea and fever in orders. 4. The positive results were obtained in 73 percent of sputum AFB smear (11 cases of 15 cases). 60 percent of AFB culture (3 cases of 5 cases) and 58 percent of bronchoscopic biopsy (14 cases of 24 cases). 5. Complete pulmonary function test was done on 19 cases and showed normal result in 6 cases, restrictive pattern in 8 cases and small airway dysfunction in 5 cases. No case of obstructive airway disease was detected. 6. Associated disease were hypertension (2 cases), tuberculous meningitis (1 case), diabetes mellitus (1 case), and cataract (1 case). 7. The site of bronchoscopic lesion on bronchoscopic examination were as follow; 8. All 25 patients were treated with anti-tuberculosis therapy and 6 patients were treated with additional steroid therapy because of severe respiratory symptom and showed dramatic improvement of symptom as well as lung function.

PURPOSE: The study has been done to evaluate the significance of APR test predictive of neonatal infection. METHODS: A study was made on 76 cases of clinically infeected neonates who had been admitted at the NICU of Chungnam National Unoversity Hospital during the period from January, 1996 to July, 1996 in order to know the significance of APR test predictive of neonatal infection. RESULTS: 1)The APR test Of Control group (20 cases) shows negative results on 19 cases (95%) and positive result on 1 case (5%). 2) The APR test of Patient group (76 cases) shows negative results on 17 cases (22.3%) and positive results on 49 cases (77.7%). Of cases with positive result, one points were on 23 cases (30.5%), two points were 25 cases (32.8%), three points were on 11 cases (14.4%) and More than one point were of 59 cases. The sensitivity of APR test, WBC count and CRP is 77.7%, 35% and 62.496, respectivitly. As above result, APR test has a high sensitivity. 3) APR positive values are not significantly different between those of premature and fullterm patients. 4) APR values are more significant than WBC count or CRP value to predict the neonatal infection. 5) The APR test is rnore useful for prognostic correlation than other index. CONCLUSION: APR test is very sensitive and significantly useful predictive of neonatal infection.

The effects of BCG and vitamin A acetate, either alone or in combination were studied on rats with bladder tumors induced by N-butyl -N-(4 -hydroxybutyl) nitrosamine. Therapy was started at week 12 and all rats were sacrificed at week 20. Vitamin A acetate therapy significantly reduced the mean number of tumors and the incidence of bladder cancer. The combination of vitamin A acetate and intraperitoneal BCG therapy, more effectively reduced the mean number of bladder tumors and the incidence of bladder cancer than vitamin A acetate therapy alone did. BCG therapy also significantly reduced the mean number of tumors and the incidence of bladder cancer. The difference between the effect of intraperitoneal BCG injection and that of intravesical BCG was not statistically significant. The combination therapy of BCG and vitamin A acetate more effectively reduced the mean number or tumors than BCG therapy along did. The incidence of bladder cancer was also reduced though the statistical significance was not definite (p =0.07). The above results suggest that vitamin A acetate and BCG therapy after initiation of precancerous lesions, alter favorably the course of the experimental bladder cancers in rats and the combination of the two does more effectively.

Prognosis and biologic behavior of malignant ovarian tumors have been assessed by clinical staging, morphological grading and many other variables. Recently DNA ploidy measured by flow cytometry has been suggested as an additional important indicator of the tumor behavior and prognosis. The author measured DNA ploidy, S-phase fraction and DNA Index in 36 patients of epithelial ovarian tumors(17 were malignant, and 19 were borderline) by flow cytometric analysis of paraffin embedded tumor blocks. Comparing with FIGO stage, tumor grade, histologic type and others, the author investigated the clinical significance of the results of flow cytometric analysis. The results obtained as follows : (continue)

Female urethral injury are very uncommon and encountered during traffic accident, trauma, instrumentation, operation and delivery. Treatment modalities are determined by the level of urethral injury. The result was better in the cases of rapid operative treatment than delayed one. In this report the clinical findings, patterns of injury and surgical managementof 4 cases were reviewed.
