PURPOSE:This study was carried out to evaluate the relationship with other clinicopath ologic factors and prognostic significance of tumor microvessel density in colorectal car cinoma. MATERIAL AND METHODS: 71cases of primary colorectal carcinoma (Modified Astler-Coller stage B and C) were analysed retrospectively who underwent curative resection at Wonkwang university hospital from September, 1991 to September, 1993. Male was 39cases. Age under 60 years was 31cases. 5 year survival rates were 80% (50 cases) in stage B and 52.4% (21 cases) in stage C. Tumor microvessels were stained by immuno histochemical method using anti-CD31 on paraffine embedded tissues, and were counted within 10x objective field (about 0.74 mm2) in the area of the most intense neovascu larization. RESULTS: Mean microvessel Density (MVD) was 56.3+/-18.0 (range 19~128). MVD was 55.2 in 11 cases of nonrecurrent group and 73.5 in 10 cases of recurrent group in stage C (p=0.012). There was no significant association between MVD and other parameters such as age, sex, tumor location and size, CEA, lymph node metastasis, and survival. The 5 year survival rates of 33 cases of MVD< or =56 and 38 cases of MVD>56 were 84.9 and 60.5% respectively(p<0.05). 5 year survival rates of MVD< or =56 groups adjusted for age, sex, tumor location, differentiation, and recurrence were higher than those of >56 groups. 5 year survival rates of MVD < or =56 and >56 groups in stage C were 100% (5 cases) and 37.5% (16 cases) (p<0.05). CONCLUSION:Tumor microvessl density may have somewhat prognostic significance in colorectal carcinoma.

Backgronud : Postoperative pain control became anesthesiologist's familiar yield, so many anesthesiologists are very interested in opioid and local anesthetic's characterestics and there cardiovascular effects. It's important which anesthetic has the best pain killing and the least cardiovascular effect. We used epidural opioid and local anesthetics and intravenous opioid to investigate their pain killing and cardiovascular effects. METHODS: We studied 50 patients undergoing gastrectomy. An epidural catheter was placed via the T8-9 or L1-2 interspace. Epidural fentanyl group (Ep-F) received fentanyl 2 microgram/kg in 10ml saline, epidural bupivacaine group (Ep-B), 10 ml 0.25% bupivacaine, and epidural lidocaine group (Ep-L), 10 ml 1.5% lidocaine, epidurally; intravenous fentanyl group (IV-F) received fentanyl, 2 microgram/kg. 50% of the original dose was repeated every hour until the operation ended. Control group was given nothing before general anesthesia. Cardiovascular data was compared between those before and those at 1hour after skin incision. The time interval between end of the operation and the time of first analgesic requirement and the total number of intramuscular analgesic requirements during the first 48hours postoperatively were compared. RESULTS: Urinary output during surgery was significantly larger in group Ep-F. Group Ep-L developed more frequent episodes of hypotension. Group Ep-F, group IV-F and control group required higher enflurane concentrations. CONCLUSIONS: Group Ep-F was accompanied less hypotension and postoperative analgesic requirements were reduced.

Statistical survey was made on out-patients and in-patients in the Department of Urology, Seoul National University Hospital during the period from January to December in 1964. Of 2,873 out-patients including 2,346 males and 527 females, 234 cases (171 males and 63 females) were hospitalized and various operations were performed on 195 occasions. The following tables are self-explanatory.

A clinical observation was made on the bladder tumors of the inpatients in the Department of Urology, Seoul National University Hospital during the period January. 1957 through June, 1967. During the period, of 1.836 cases (1,372 males and 464 females) hospitalized, 99 cases had bladder tumors, giving a rate of 5.3%. Among the 99 cases, 88 cases could be studied and the following results were obtained. 1. Among the 88 cases, 68 cases were male and 20 cases were female with ratio of 3.4 to 1. 2. Age distribution ranged from 22 years to 79 years, 70.5% of cases were in the age group of 4o~69. 3. Hematuria which occurred in 80 cases is the most common initial disturbance. The other common manifestations are frequency, dysuria and urinary retention as in order. 4. 54 cases or 61.5% of the cases visited to hospital within one year after the occurrence of initial disturbance. 5. 37.8% of the cases involved in the lateral wall, 30.7% in the posterior wall, 12.1% in the entire wall and 7.9% in the trigone. 6. As the methods of treatments, T.U.R. was performed 43 times, 29 time of electrocoagulation through suprapubic cystotomy and 12 times of partial resection of the bladder were done. 7. Among 88 cases, pathologic diagnosis was made in 72 cases. Transitional cell carcinoma is observed in 62 cases, adenocarcinoma in 4 cases, metastatic carcinoma in 3 cases and squamous cell carcinoma in 1 case. 8. 27 (30.7%) cases had had follow-up studies one or more times for 2 months to six and half years. At the first follow-up study 6 cases were tumor free and 21 cases had recurrent tumors.

The anterior cruciate ligament(ACL) is one of the main structures which have a stabilizing function of the knee. If a knee with a complete tear of ACL is not treated operatively, progressive instability develops, and the knee has a high risk of incurring meniscal is required. From March, 1989 to December 1992, we reconstructed ACL using patellar tendon with Kennedy-ligament augmentation device(LAD) in 26 patients. Nine patients had acute injuries and 17 patients had chronic rupture. In eleven patients operation was done arthroscopically, and in fifteen patients operation was done by arthrotomy. We used quadriceps tendon-patellar periosteum-patellar tendon in 16 cases and bone-patellar tendon-bone in ten cases. The length of follow-up ranged from 6 month to 33 months (mean; 10 months). We obtained satisfactory results in 22 cases.
