Since Dr. Angell introduced cryopreservation method for tissue preservation in 1980s, it became a preferred method for cardiovascular tissues. Cryopreservation has been proven to provide better cell viavility and clinical result than any other preservation method. The quality of cryopreserved cardiovascular tissue is a very critical point of patients' survival when transplanted. To obtain high quality cryopreserved tissue, each processing methods from harvesting to delivery should be standardized. Various factors, such as range of possible tissues, acceptable ischemic time, temperature during transportation, facility for processing, method of freezing, use of cryoprotectant, method of storage, condition of delivery, and method of thawing for cardiovascular tissues should be standardized. Different standards should be established and applied to different tissues. Various kinds of tissues can be harvested from each living or cadaveric donor. Therefore, it is reasonable to harvest and handle all tissues in one laboratory by one tissue bank. In U.S.A, tissue banks are operated under standardized condition. The American Association of Tissue Banks affords the certification of specialist and tissue banks on very strict conditions, and provides the Food and Drug Administration with consultation in making regulations regarding tissue transplantation. In Korea, tissues have been simply stored in refrigerator since mid 1990s, and cryopreservation method is getting popular. Tissue banking has been started recently and now six major hospitals treat the cardiovascular tissues and are equipped with good facilities. Korean Association of Tissue Banks was established last year and now setting up regulations and standards. In Conclusion, I suggest that the cardiovascular tissue bank should belong to a university hospital till regulations and standards are completed. And then commercial tissue bank will be able to take it over to manage more tissues. The financial state of tissue banking is also an important point to be considered to balance between quality control and easy access to the public. Also the cost of cryopreserved allograft should be covered by medical insurance.

A clinical observation was made on 216 cases of genitourinary tract tumors of the impatients in the Department of Urology, Chosun University Hospital during the 10 years, from January 1972 to December 1981. The results were as follows: 1. During this period, of 1282 cases hospitalized, 216 cases (180 males, 36 females) had tumors of the genitourinary tract, at the rate of 16.8%. 2. The male to female ratio was 5:1 (180:36). 3. The majority of the patients(88.4%) were distributed over age of 40 years. 4. The prostate was the most commonly involved organ (51.3%) and the tumors of the bladder, kidney, testis, penis, pelvis, ureter, urethra were in order. 5. Histopathologically, B.P.H. was observed in 43.1% of all operative tumors, transitional cell carcinoma of bladder in 28.1% and renal cell carcinoma in 5.6%. 6. Operations were performed in 160 patients (74.1%).

Due to its anatomical position and histological characteristics of thin capsule and low abundance of connective tissue, the spleen is a prime target for damage from blunt injury or during operation. Until recently, total splenectomy has been considered as safe operation for splenic injuries. But now, splenic salvage procedure or non operative treatment have become the standard care with knowledge for immunologic function of spleen, development of radiologic examination such as ultrasonography and abdominal CT, and report about high risk of mortality after splenectomy. Authors have experienced 27 patients with splenic injury admitted to the emergency department during 5 years 4 months period from 1991 to 1996. Among them, 10 patients were received total splenectomy, 2 patients partial splenectomy, 8 patients splenorrhaphy, one patients hemostasis, and 6 patients underwent nonoperative management.

During the period of 9.5 years from September, 1985 to March, 1995, 32 cases with spontaneous closure in simple ventricular septal defect(VSD) were observed and evaluated at Yeungnam University Hospital, and those were confirmed by 2D-echocardiogram. The results were as follows: 1. Among these 32 cases, there were 23 cases(71.9%) of perimembranous VSD, 8 cases(25.0%) of muscular VSD and 1 case(3.1%) of subarterial VSD. Septal aneurysms appears to be main mechanism of spontaneous closure of VSD because of the presence of septal aneurysm in all cases with spontaneous ',;losure of a perimembranous VSD. 2. The size of the defect was variable in diameter, but 27 cases(81.2%) were less than 5 mm. 3. The mean age was 12.1 months at spontaneous closure with the range from 1 month old to 72 months. 4. The mean weight was 9.0 kg at spontaneous closure. 5.--Among these 32 cases, 3 cases had the clinical evidence of cardimegaly or congestive hert -failure during infancy. 6. Male to female sex ratio was 1.5:1

To estimate the postmortem interval (PMI) by using entomological evidence, species identification of forensically important flies is mandatory. However, the traditional species identification method, which relies on the key morphological features of adult flies, is not always available to investigators and has limitations to the immature samples. Because of these limitations, species identification using DNA sequences has long been an issue in the field of forensic entomology. In this review, I have briefly described the basic principles of molecular species identification and phylogenetic analysis and their applications in forensic entomology. I also recommend an experimental and statistical method to identify unknown fly samples obtained from the field.
