Korean Journal of Urology 1989;30(3):314-319
Carcinoembryonic antigen(CEA) was measured in the serum and urine of 46 patients with bladder cancer and 15 patients with non-cancer disease as control group at the Paik Hospital. Pusan during the period from January, 1986 to June, 1988. The following results were obtained. 1. The upper limits of normal serum and urinary CEA levels in non tumor control group were 3.7 ng/ml and 2.3 ng/ml. Mean and positive rate of serum and urinary CEA levels in bladder cancer group were 4.40 ng/ml(37.0%) and 21.52ng/ml(65.2%). 2. Mean urinary CEA level was correlated significantly with the stage, grade and size of bladder cancer but no significance was seen in serum CEA. In the advanced cases(Stage C, D), serum CEA levels were elevated. 3. The diagnostic rate was not elevated in spite of urinary CEA determination combined with urinary cytology. After transurethral resection of cancer mass and radiation therapy, urinary CEA level decreased. As a result, serum and urinary CEA determinations in bladder cancer have no diagnostic value, but it will be useful in the study of the extent of cancer, effect of therapy, recurrence and prognosis.

To elucidate the effects of dimethyl sulfoxide on of myocardial and endothelial cells in culture, the cells were exposed to 10% dimethyl sulfoxide in culture medium for 1 hour at 48 hours after cell isolation. The general morphology and the cytochemical reaction of marker enzymes for mitochondria and Golgi complexes were investigated. The results were summarized as follows 1. DMSO induced elongation and narrowing of the cells and increase of mitochondrial reaction in myocardial cells. 2. DMSO induced destruction and disruption of myofibrils in myocardial cells resulting in increase of contractile activities. 3. In the endothelial cells, DMSO suppressed proliferative activities but thiamine pyrophosphatase reactions were enhanced indicating increase of Golgi complex activity. 4. DMSO seemed to hamper with the adhesiveness and motility of the endothelial cells causing the decrease of the number of cells in vitro.

BACKGROUND: Cardiopulmonary bypass during open heart surgery causes systemic inflammatory respose. IL-10 is an anti-inflammatory cytokine that inhibits inflammatory process and protects organ function by down regulation of pro-inflammatory cytokine release and maintenance of blood level balance with pro-inflammatory cytokines. MATERIAL ateial and Method: Plasma IL-10 levels were measured and analyzed in 22 patients who underwent open heart surgery (11 cases of coronary artery bypass graft, 11 cases of valve replacement) under cardiopulmonary bypass since 1988 January to July at Department of Thoracic and Czardiovascular surgery, Yeungnam University Hospital. 1g of methylprednisolone was administrated to thirteen patients randomly. Blood samp.es were taken and collected at the time of induction of anesthesia, 10 min before cardiopulmonary bypass, 10 min after starting of CPB, 10 min aftr aortic cross clamping, 10 min after ACC release, and 10 min, 2 hours, and 5 hours after CPB respectively. The plasma levels of IL-10 were determined by enzyme-linked immunosorbent assays (ELISA). Wilcoxon-Raule Sum test was used for statistical analysis. In all 22 patients, cardiopulmonary bypass time was used for statistical analysis. In all 22 patients, cardiopulmonary bypass time was 171+/-41.4 min and aortic cross clamp time was 118+/-36.5 min. Peak IL-10 level was achieved at 10 min after ACC (361.0+/-52.81pg/ml) and was decreased sharply at 2 hours after CPB. Peak IL-10 level was correlated positively with aortic cross clamp time (p=0.011); however, it did not correlated with bypass time (p=0.181). In valve replacement group, mean IL-10 level at peak point was 567.89+/-107.69 pg/ml and was significantly higher than that of coronary artery bypass group (205.67+/-192.70 pg/ml) (p<0.001). ACC time in valve replacement group was significantly longer than that of coronary artery bypass group (p<0.01), however, bypass time was not (p=0.212). Thirteen patients with steroid pretreatment before starting of CPB showed relatively higher plasma IL-10 level than in control group, however, no statistical significance was noted (p=0.19). CONCLUSION: plasma level of IL-10 was increased in association with cardiopulmonary bypass and revealed peak at 10 min after ACC release. IL-10 level was correlated positively with ACC time. Therefore, systemic inflammatory respeonse in association with cardiopulmonary bypass could be decreased by reducing ACC time during cardiac surgery.

Congenital bronchobiliary fistual is a rare disease with unclear etiology. An abnormal tract communicates the tracheobronchial junction to a hepatic segment, usually the left lobe. Billous sputum, a positive HIDA(o-Dimethyliminodiacetic acid) scan, and a trification at the level of the carina lead to the diagnosis, which can be confirmed by bronchoscopic contrast injection. We experienced a case of congenital bronchobiliary fistual in a 27-day-old girl. Our case is reported with literature reviews.

BACKGROUND: This study was performed to evaluate the incidences, the risk factors, and the clinical course of the hyperamylasemia in patients who underwent open heart surgery under cardiopulmonary bypass. MATERIAL AND METHOD: Thirty seven patients who underwent cardiopulmonary bypass were studied at Department of Thoracic & Cardiovascular Surgery, Yeungnam University Hospital, from July 1997 to June 1998. The thirty seven patients were divided into two groups, 13 patients in group I had normal serum amylase levels and 24 patients in group II had hyperamylasemia. Mean serum amylase(IU/l) levels and 24 patients in group II had hyperamylasemia. Mean serum amylase(IU/l) levels of gorup II showed 54.3+/-4.6, 78.0+/-9.2, 372.0+/-103.4, 460.5+/-80.4, 280.4+/-46.6, and 131.0+/-15.6, preoperative, immediate postoperative, at postoperative 1, 2, 3, and 7 days, respectively. In group II, serum amylase level of the postoperative day 2 was the highest and was significantly higher than that of the preoperative day (p<0.001). Serum amylase level started to decreased at postoperative day 3 and returned to the normal level at postoperative day 7. Significant clinical symtoms of overt pancreatitis were not shown in patients in group II. The following perioperative variable such as diagnosis, cardiopulmonary bypass time, aortic cross clamping time, mean systemic pressure during bypass, and administration of steroid were compared between groups. There were no significant differences between groups. In all patients, Serum amylase level of postoperative day 2 and aortic cross clamping time were correlated significantly (p=0.047). CONCLUSION: Serum amylase level after cardiopulmonary bypass could be elevated postoperatively and serum amylase level of POD 2 was considered to have significant correlation with aortic cross clamping time. Shortening of aortic cross clamping time will help in reducing the hyperamylsemia. In this study, although significant clinical symptoms and overt pancreatitis were not seen from hyperamylsemic patients, careful clinical observation of hyperamylasemia would be necessary.

An experimental study in vitro using piezoelectric extracorporeal shock wave lithotriptor(EDAP LT-01) and urinary stones removed from the patients by surgical method has been performed. The purposes were 1) to correlate the stone components and sizes with the storage of complete fragmentation, 2) to examine the screening effect and 3) to observe the stone fracture mechanism in urinary stones. The following results were obtained. 1. Tribasic calcium phosphate stone, magnesium ammonium phosphate stone and uric acid stone fractured more easily than calcium oxalate stone. In the case of small stones(diameter 0.5 cm), all stones fractured at relatively low storage. Large stones (diameter 1.5 cm) fractured at high storage with wide variations according to components. 2. Magnesium ammonium phosphate stones tested to observe for screening effect showed that a high storage was needed for complete fragmentation(about 2 times) when the stone debris was not removed. 3. Urinary stones fractured first on the front surface. When the stones showed lamellae, which were separated first by shock wave, thereafter each lamella was broken.

The long QT syndromes have been classified into acquired or inheritary forms, both of which are associated with a characteristic type of life-threatening polymorphic ventricular tachycardia called torsade de points. Beta-adrenergic blocker is the first cholic treatment, but in those whom cardiac events are not prevented by beta - blockade, left thoracic sympathetic ganglionectomy may be useful in selected cases. A 50-year-old woman had an recurrent syncopal attack in which she was unconscious for 1-2 min and 1-2 times a month for 10 years. The EKG revealed that QT & QTc intervals were 744 and 632 msec respectively. Treatment with Beta-adrenergic blocker and calcium channel blocker was ineffective in preventing recurrence of syncopal spell. Therefore, she underwent left thoracic sympathetic ganglionectomy with thoracoscope. During the 9 months after operation, she was free of syncopal episodes and is doing well.
