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.

In oder to determine values for the body weight by height groups for Korean adults men who are fully grown up 4028(30-39 age-group:2318, 40-49 age-group: 1340, and 50-59 age-group:370) apparently healthy males subjects were randomly selected for the measurement of body weight by height groups. 1) The average body height and weight of Korean adult men were 168.3+/-4.6cm and 63.4+/-7.1kg in 30-39 age group, 167.7+/-4.7cm and 63.4+/-7.4kg in 40-49 age group, and 167.3+/-5.2cm and 63.3+/-8.0kg in 50-59 age group. 2) A correlation coefficient of r=+0.52(P<0.001) between body height and weight was found in 30-39 ate group of 2318 subject, r=+0.48(P<0.001) in 40-49 of 1340 and r=+0.53(P<0.001) in 50-59 of 370 with the aid of there coefficients of linear regression body weight and height were established for male as follow; for 30-39 age group, Y(weight in kg)=0.81X(height in cm)-73.02, 40-49 age group, Y(weight in kg)=0.74X(height in cm)-61.82, 50-59 age group, Y(weight in kg)=0.82X(height in cm)-73.83. 3) With the aid of above listed various equation standard values for body weight by height group, with over weighing and under weighing values were established. 4) Standard bodyweight of Korean was lower than those of American, Japanese and several other formulas for ideal body weight.

BACKGROUND: Elevated plasma homocysteine level (tHcy) is one of the risk factors for coronary artery disease (CAD). It has been demonstrated that doses of folate as low as 0.25 mg/d significantly decreased tHcy in healthy, young women. Homozygosity for C-677T polymorphism in the Methylenetetrahydrofolate reductase (MTHFR) gene seems to be correlated with an elevated tHcy in the situation of low blood folate concentrations. In this study, we evaluated the response of the low dose folate treatment on the tHcy and whether genetic variation of MTHFR gene might influence the response of the folate treatment in korean CAD patients. METHODS: CAD patients (n=3), confirmed by coronary angiography, and controls were analyzed for CAD risk factors including tHcy and MTHFR gene C-677T polymorphism. Patients were treated with daily 0.25mg folate for 4weeks and the level of folate and tHcy was reevaluated. RESULTS: Low dose folate treatment for 4weeks significantly increased folate level (38%, p<0.05), but did not influence tHcy. Patients whose tHcy was decreased with folate replacement (n=1) were characterized by low basal folate level (7.0+/-2.6 vs 9.1+/-2.7 nmol/L, p<0.05) and high basal tHcy (12.6+/-4.4 vs 8.6+/-2.4 micromol/L, p<0.05) compared to the patients whose tHcy was unaffected or increased with folate. tHcy was decreased 11.2% and 12.6% each in patients with high basal tHcy (>10 micromol/L) and low folate level (<7 nmol/L), but increased 7.3% and 4.5% in patients with low tHcy and high folate level (p<0.05, each). MTHFR C-677T polymorphism was not a significant contributing factor for tHcy and for the response to folate treatment. CONCLUSION: Low dose folate treatment can decrease tHcy in CAD patients with low basal folate level and high basal tHcy. C-677T MTHFR gene mutation does not influence the effects of low dose folate treatment on tHcy in Korean CAD patients.

1. In total 33 cases of cataract, measurements of the corneal curvature(radius) were performed preoperatively and postoperatively. 2. Among 6 cases of below 40 year old, extracapsular cataract extraction were 5 cases. While 23 cases were done in intracapsular extraction among 27 cases of more than 40 year. 3. At two month after the operation, vertical and horizontal curvatures are closer to that of preoperative condition than in 1 month after the operation. 4. 2 month after the operation, vertical curvatures are getting flat in 66 %, while more cases showed tight horizontal curvatures than flat one.
