Hydronephrosis due to uroteropelvic junction obstruction is a well recorgnized and common disorder of children and young adults. Its clinical charateristics are vague generalized symptoms, so early detection is not easy. We reviewed fourty five cases of hydronephrosis due to ureteropelvic junction obstruction in the Department of Urology, Chungnam National University, from January, 1981 to December, 1990. The results are as follows; 1. Age distribution of hydronephrosis was 20 cases in old aged group(above 20 years old), 10 cases in 1st decade, 9 cases in 2nd decade and 6 cases in infants. Sex distribution was 28 cases(62.2%) in male and 17 cases(37.8%) in female(male to female ratio was 1.6: 1). 2. Of 45 cases, 39 cases(98.7 %) were unilateral and 6 cases(1.3 %) were bilateral. 'Left kidney was more involved than right. 3. Associated diseases were 13 cases(28.9%), of which congenital anomalies were 6 cases, such as horseshoe kidney(3 cases), ureterocele(1 case), complete duplicated ureter(1 case) and contralateral renal hypoplasia(1 case), and acquired diseases were 7 cases, such as pyonephrosis(3 cases), stone(3 cases) and spontaneous renal rupture(1 case). 4. The operative methods were nephrectomy(23 cases), pyeloplasty(22 cases), isthmectomy(3 cases) and partial nephrectomy(1 case). 5. The pyeloplasty was successful in 19 cases(86.4% ).

A patient with uncontrollable postoperative renal hemorrhage was successfully treated by selective injection of gelfoam into the anterior inferior segmental branch of right renal artery. Follow up arteriography was done 16 days later. It revealed persistent occlusion of the bleeding vessels. This method is a simple effective procedure in cases of renal hemorrhage to diverse etiology without responsive management.

Hyperreflexic bladder is a common problem in spinal cord lesion above sacral segment and the management remains a challenge. As a result of markedly elevated bladder pressures these patients often present with urinary incontinence, recurrent urinary tract infection and renal deterioration lastly. We treated the three hyperreflexic bladder patients (2 spinal cord lesions & 1 cerebrovascular accident) with 6% phenol injection through the third sacral foramen for nerve root block. Average of bladder capacity increment was above 300ml and maximal intravesical pressure did not rise above 40cmH2O. Continence was maintained in all cases. Therefore, all patients performed self - catheterization successfully and the volume was 300-500m1. There was no definitive complications. The third sacral nerve root block may be used for hyperreflexic bladder patients who cannot be controlled by anticholinergics.

음이온교환수지를 이용한 아미노산의 분리

이중화 세종대학교 1986 세종대학 논문집 Vol.13 No.이공

For the isolation of pure amino acids, it is advantageous to have available chromatographic systems. The method previously outlined in the preliminary form wherein amino acid are eluted from cation exchange resine with citrate solution has proved useful for the seperation of amino acid, but the resolving power has not been sufficient to permit isolation of all the common constitution. In the procedure described in the present study, aspartic acid, glutamic acid, and typosine are isolated by passage of the column of acetate form of Dowex 1×4 using 0.5N acetic acid as eluent and the remaining components of the mixture are seperated through 500W×4 by elution with 1 to 5 N HCI.

산성 및 중성의 아미노산인 Asp. Thr. Ser. Glu. Gly. Ala. Val. Met. Leu. 은 0.9×50cm의 양이온교환 수지관(Amberite 1R 120)에서 0.2N 시트르산 완충용액 (pH 3.25와 4.25)을 이용하여 분리하였고 염기성 아미노산인 Tyr. Lys. His. Arg. 은 0.9×15cm의 같은 이온교환 수지로 충진한 분리관에서 같은 완충용액(pH 5.28)으로 분리하였다. 이온교환 수지에서 용리되는 각 아미노산의 거동은 아미노산의 해리상수와 등전점의 값에 비례하였다. The acidic and neutral amino acids of Asp. Thr. Ser. Glu. Gly. Ala. Val. Met. and Leu were seperated through 0.9×50cm cation resin (Amberite 1R 120) column by using the eluent of 0.2N-citrate buffer (pH 3.25and 4.25) and basic amino acids of Tyr. Lys. His. and Arg. were seperated through 0.9×15cm column of the same resin by using the same eluent (pH 5.28). The elutional behaviors of amino acids on ion exchange resin were directly proportional to their dissociation constants and the values of isoelectric point respectively.

Zinc is an antibacterial factor and its levels in the expressed prostatic secretion correlate with the secretory function of the prostatic gland. So we have performed an assay for zinc on serum and expressed prostatic secretion in 25 consecutive patients with documented chronic prostatic inflammation along with 29 controls. There is no remarkable difference(p>0.5) of zinc concentration in the serum between patient group(mean:69.7ug/ml) and control group(mean:69.9ug/ml), but in the expressed prostatic secretion, the difference of zinc concentration between patient group (mean:517ug/ml) and control group (mean: 1071. 9,ug/ml) was significant(p<0.005).

The oligomers of chlorophyll-a (Chl-a concn.4.6×10^-5M) were identified by the measurment of absorbance and fluorescence at each red and soret band in diethyl ether and benzene after the addition of n-propyl alcohol to chl-a solution, and this method was applicable to identify the low concentration of chl-a oligomers which were not able to identify with the spectra in the solution. The oligomers were also confirmed from the soret bands of absorbance and fluorescence excitation spectra measured by computer in n-hexane and iso-octane solvents.

I compared 2 different flow systems of resectoscope for transurethral resection of the prostatethe intermittent drainage resectoscope(Group A) and the continuous flow resectoscope(Group B). In 53 patients were undergone the transurethral prostatic resection due to benign prostatic hyperplasia. Of the patients 34 were undergone the resection with intermittent drainage resectoscope and remaining 19 patients were resected by continuous flow resectoscope. The resection rate, the required irriagnt volume, changes of electrolytes, operative blood loss and postoperative complications were compared. The results were obtained as follows: 1. The resection rate was slightly higher with Group B but there was not statistically significant in two group(p=0.598). 2. The required irrigant volume was greater with Group B but no significance was noted(p=0.098). 3. Serum sodium concentration changes was more greater with group B(p=0.018). There was no significant difference in potassium changes between two groups. 4. Hemoglobin and hematocrit of group A were more decrease than of group A(p=0.000). 5. Postoperative complications, which were related with types of resectoscope, were not significant with two groups. 6. Approximately 5 percent of the patients undergoing prostatectomy for presumed benign prostatic obstruction was found to have incidental adenocarcinoma.
