Primary tumor of the renal pelvis and ureter is relatively rare disease, but usually malignant. It's prognosis is dependent upon the early detection, accurate diagnosis, procedure for treatment, and tumor grade and stage. Therefore, urologist should endeavor after accurate diagnosis and definitive treatment. A clinical observation was done on the 11 patients with renal pelvic tumor and the 3 patients with ureteral tumor at the Department of Urology, Kyungpook National University Hospital during the period of 4 years from January, 1978 to December, 1981. The results were as follows: 1. There were 9 men and 5 women, giving a ratio of 1.8 to 1. The average age at presentation of the 14 patients was 51.4 years. 2. On excretory urogram, nonvisualization of the kidney was the most prevalent sign in 10 patients. Retrograde pyelogram was done in 11 patients in whom findings of IVP were not sufficient for diagnosis. Renal angi0graphy was done in 9 patients. 3. Urine cytology was positive in 2 of 14 patients. 4. Of the 13 patients treated, 12 were proved to have transitional cell carcinoma, and 1 was leiomyoma. In 3 of the 11 patients with renal pelvic tumor, Concomitant ureteral tumor was present at diagnosis. And in 2 of the 11 patients with renal pelvic tumor developed subsequent urothelial tumors in the ureter and/or bladder after simple nephrectomy. 5. Nephroureterectomy including resection of a bladder cuff was done in 11 patients, and in 2 of these was also performed lymphadenectomy. Simple nephrectomy was done in 2 patients with renal pelvic tumor under the misdiagnosis of renaltuberculosis. 6. Postoperative complications developed in 3 cases, wound infection, pneumothorax, and death, in each case.

PURPOSE: To evaluate the effectiveness of intreaepithelial photorefractive keratectomy (IE-PRK) for the treatment of myopic regression after laser in situ keratomileusis (LASIK) METHODS: 38 eyes of 22 patients who had previous LASIK for myopia were selected and retreated with IE-PRK, in which a photoablation was performed directly in the epithelium without damage to Bowman's layer. All eyes were elapsed at least 6 months after the LASIK. Follow-up was up to 6 months and within +/-0.50 of emmetropia on 6 months after surgery was considered as a success. RESULTS: Before IE-PRK, the eyes regressed to a mean of .1.26+/-0.45 D spherical equivalent (SE). The mean SE at 1 week after IE-PRK was .0.44+/-0.88 D, 1 month was .0.59+/-0.45 D, 3 month was .0.63+/-0.41, 6 month was .0.62+/-0.43 (p<0.05). 23 of the 38 eyes (60.5%) had refraction within +/-0.50 and were considered as successfully treated. Preoperative mean best corrected visual acuity (BCVA) was 0.33+/-0.18 (Snellen equivalent) and final mean BCVA was 0.77+/-0.99 (p<0.01). There were no significant complications of corneal flap. CONCLUSIONS: The results of this study indicate that intraepithelial photorefractive keratectomy appears to be a safe means for treating patients for regression after LASIK procedure. But success rate was not so good as the enhancement. Controlled studies with larger population will be necessary to evaluate the accuracy of the method more correctly.

PURPOSE: To compare results of laser in situ keratomileusis (LASIK) and laser epithelial keratomileusis (LASEK) for the treatment of high myopia. METHODS: In this study, 129 patients with a manifest refraction over -6.00 diopters were assigned two groups for 144 eyes of 72 patient treated with LASIK and 114 eyes of 57 patients treated with LASEK. Uncorrected visual acuity, manifest refraction, corneal haze and other complications were reviewed in LASIK- and LASEK-treated eyes at 6 months after the operation. RESULTS: At the 6-month follow-up, there were significant between-eye differences in uncorrected visual acuity and mean spherical equivalent. And LASEK-treated eyes had more corneal opacity and it makes decreased uncorrected visual acuity. CONCLUSIONS: Both laser refractive surgeries were safe and effective methods to treat eyes with high myopia. But LASIK procedure may prove superior to decrease corneal opacity and visual predictability.

PURPOSE: We investigated the adhesion rate and morphologic change of lens epithelial cell (LEC) according to materials of intraocular lens (IOL). With the results, we estimated the appearance and characteristics of posterior capsular opacity after cataract extraction. METHODS: LECs were prepared from fresh bovine lens. Hydrophobic acylic IOLs such as Acrysof(R) and Sensar(R) and hydrophilic acrylic IOLs such as Corneal(R) were tested. On the days 2, 9 and 12 of LEC culture, we calculated the adhesion rate and observed the cellular morphologic changes. Immunostaining with alpha smooth muscle actin (SMA) was performed. RESULTS: Adhesion rate was higher in hydrophilic lens on the days 2 and 9 (p-value=0.029). Acrysof(R) had the lowest adhesion rate. LEC in hydrophobic IOL showed differentiation to myofibroblast that was strong positive for SMA. LEC in hydrophilic IOL preserved natural cellular morphology until the day 12. Immunostaining with SMA was nearly negative. CONCLUSIONS: Hydrophobic acrylate induced much differentiation from LEC into myofibroblast, but had low adhesion rate. Hydrophilic acrylate does not induce the differentiation, but has high adhesion rate.

Plsama and urinary Mg were measured in relation to EKG change in 24 patients with liver cirrhosis, and summarized as below. 1. Plasma albumin and Ca were below normal, however Na, K, and Mg level were in the lower limit of normal. 2. Abnormal EKG findings were QT prolongation, ST elevation, peaked T, low T, ST depression and U wave in the order of frequency. 3. Coefficient of correlation between plasma Mg and QT prolongation was -0.5 compared with that of Ca-0.28. 4. Mg depletion was moderately correlated with plasma albumin (r=0.59). 5. Marked urinary Mg excretion in the presence of normal plasma Mg suggest that plasma Mg level poorly reflect total Mg depletion.
