1.Development of Blood Bank Management Program with Personal Computer for Small to Medium Size Hospitals.
Korean Journal of Blood Transfusion 1996;7(2):197-205
A recently increased need to a computerized program for correct management of grouping and dealing of bloods at small to mize hospitals made us develope the blood bank management program with a personal computer. Some hardwares(PC 486, bar code reader and printer) and softwares(Microsoft Foxpro version 2.5 for main development and Hanmac 2.5 for Korean BIOS) were used as materials, and frequent upgrades were performed during the develpment period. The program was consisted of eight main functions including grouping, input, output, reinput and expire of bloods, and autotransfusion, apheresis and directed transfusion. The program may be a good tool to reduce blood accidents and to enhance quality of blood banks at small to medium size hospitals.

Urachal carcinoma is an uncommon neoplasm associated with a poor prognosis. We have encountered two another cases of urachal adenocarcinoma recently 5 years after our first report. The common sign of urachal cancer was painless hematuria. We diagnosed the specific site of origin preoperatively by means of computerized tomography. One patient was performed partial cystectomy and another was total cystectomy with double barrel ureterocutaneostomy. A brief review of the literature of urachal adenocarcinoma was also made.

Case 1 was a 55-year-old housewife with the 1-year history of mild recurrent gross hematuria and recent history of massive hematuria following radiation treatment for uterine cancer 7 years ago. Various conservative treatments showed no effect but complete hemostasis was obtained immediately after instillation of 100 ml of 4% formalin solution for 30 minutes under sedation. And to date, there has been no recurrence of hematuria or significant complications for 5 months after the treatment. Case 2 was a 45-year-old housewife with the 3-month history of symptomless gross hematuria following irradiation for a gynecologic malignancy 8 years ago. Complete hemostasis was obtained one day after instillation of 100 ml of 4% formalin solution for 30 minutes under sedation. and to date, there has been no recurrence of hematuria or any complications for 2 months after the treatment. Postradiation vesical bleeding is a very difficult condition to control and may result in total cystectomy and urinary diversion. The treatment by intravesical instillation of formalin solution for the intractable vesical bleeding is simple to perform, shows excellent effect and no significant complications, and is a highly recommendable mode of treatment for massive, uncontrollable vesical bleeding before total cystectomy and urinary diversion.

Recent development of oral and maxillofacial surgery has taken an interest in the regeneration of facial bone defects. For the reconstruction of bony defects, autogenousbone grafts have been widely used. However, there are some clinical problems ; the morbidity of donor sites, resorption of autogenous bone graft and the availability of the proper form and size. The purpose of this study is to find the proper filling materials for the bone defects. The present study was designed to evaluate the roles and regenerating capacity of maikture of freeze-dried domineralized allogenic bone and hydroxylapatite. Fifteen adult New Zealand white rabbits were used as the experimental animal, Four trephine defects were made by drilling on the parietal bone of each rabbit. The size of each defects was 8x8mm. In first group, the defect was filled with freeze-dried demineralized allogenic bone and hydroxylapatite. The defect in second group was filled with autogenous bone chip only. The third group was filled with autogenous bone chip and hydroxylapatite. The fourth group was filled with freeze-dried dimineralized allogenic bone only. The results were carefully examined grossly and micorsocopically from the 2 weeks to 12 weeks postoperatively. The following results were obtained ; 1. In the case of the graft with autogenous bone chip only, new bone formation was more active than any other groups. 2. In the case of the graft with combination of freeze-dried demineralized allogenic bone and hydroxylapatite, new bone formation was similar to the case of autogenous bone and hydroxylapatite mixture. 3. In the case of the graft with freeze-dried demineralized bone, new bone formation was observed, but less than the other groups. And the time of new bone appeared was later than the other groups. A combination of freeze-dried deminearalized allogenic bone and hydroxylapatite plays an effective role in forming new bone. The results of this study may suggest the possible usage of the mixture of freeze-dried allogenic bone and hydroxylapatite as an alternative to autogenous bone in maxillofacial orthopedic surgery.

Korean Journal of Urology 1977;18(3):217-219
The ureterolithotomy was usually performed through a longitudinal incision of the ureter in the field of urology. Many complications caused by the longitudinal incision of the ureter were very well known. Gil-Vernet has emphasized transverse incision of the ureteral calculi from his satisfactory results on 73 operations. Transverse ureterolithotomy on 7 cases were performed. Postoperative course of all cases was uneventful. This method and comparison to the longitudinal incision should be considered.

Following results were obtained through comparative investigation between lumbar and posterior vertical incision in the intrasinusal pyelolithotomy on the 28 cases of renal stones. 1. There was no difference in operation time between lumbar and posterior vertical incisions for renal stones. 2. Blood loss during operation by posterior vertical incision, as compared with lumbar incision, was reduced to a half. 3. While narcotic analgesics were used postoperatively in whole cases of lumbar incision, mild narcotic analgesics were used in a few cases of posterior vertical incision. But there was no necessity of the use of narcotic analgesics in whole cases of posterior vertical incision. 4. There was no difference in the degree of postoperative urine leakage between lumbar and posterior vertical incisions for renal stones. 5.In the posterior vertical incision for renal stones, as compared with lumbar incision, postoperative ambulation day was reduced to a half and postoperative hospitalization period was also shortened to one third. Considering above mentioned results in the posterior vertical incision operative in vasion was minimal by approach into retropritoneal space without cutting muscle layers, in addition early ambulation and discharge were possible. Especially by performing intrasinusal pyelolithotomy in the state of pyelolithotomy in situ, reoperation was possible in the case of recurrence of stones. I think posterior vertical incision seems to be a reasonable method for surgical management of renal stones.

Korean Journal of Urology 1987;28(4):599-602
The term "Milk of calcium" has been borrowed from a somewhat similar condition encountered in the gallbladder. The coexistence of stone in a caliceal diverticulum is well known but milk-of-calcium is unusual in this structure. Recently we experienced a case of milk-of-calcium in a pyelocaliceal diverticulum in a 44 year old man, so we report this case with a brief review of the literature.

This study was carried out to investigate the localization and change of the cell surface antigens, such as URO-9(Om5) and URO-10 (T43), in transitional cell carcinomas of bladder. The subjects used were normal bladder mucosae of 10 autopsy cases of fetus and 10 biopsy cases of child or adult patients with disease of other organs as controls, and neoplastic tissue of 15 cases of patient with transitional cell in carcinoma of bladder. Avidin-Biotin complex(ABC) kits(Cambridge Research Lab.) and URO-9 and URO-10 monoclonal antibodies were used and the data observed were analyzed. The results obtained were summarized as follows: 1. URO-9 expression was none of 10 fetal bladder mucosae and 3 or 10 normal bladder mucosae and URO-10 expression was none showed. 2. Of 15 cases with transitional cell carcinoma of bladder, URO-9 expression was 5, of which 1 was Ta grade II, 1 T1 grade II and the rest T2 grade III. URO-10 expression was 10, of which I was T1 grade III, 3 T2 grade III, 3 T3 grade III and 3 T4 grade III, of 15 cases of transitional cell carcinoma of bladder. As above results, the transitional cell carcinoma of bladder in low grade and low stage have tendency to express URO-9 monoclonal antibody but not URO-10 monoclonal antibody, whereas the transitional cell carcinoma of bladder in high grade and high stage were inclined to express URO-10 monoclonal antibody with variable expression of URO-9 monoclonal antibody.
