The brief history of human tissue bank is reviewed, and the current status of tissue bank in the field of plastic surgery in Korea is presented. We sent a questionnaire to 58 plastic and reconstructive surgery training hospitals. The survey was completed in 27 hospitals. The results were as follows : the number of hospitals managing a tissue bank was 16, and the remaining 11 hospitals did not manage a tissue bank. Less than 30% of the plastic and reconstructive surgery training hospitals' tissue banks were managed by the plastic and reconstructive department by itself. In the field of plastic surgery in Korea, skin banks are most popular among the tissue banks. The development of the national skin bank is needed and there are a lot of parts to be improved in the management of tissue banks.

The human semen ejaculated in a form of liquid state, coagulates immediately after ejaculation, and then liquefies again. However, the mechanisms of neither coagulation and liquefaction of semen have not been explained clearly so far, and very limited numbers of report are available, although the spermatology and andrology made rapid progress. This clinical study has been undertaken to investigate the liquefaction phenomena and practicability of the results might be applied to fertility and infertility problems. As a preliminary study, in this report the liquefaction time of various semen groups is measured and analyzed. The following results are obtained: 1. An average liquefaction time of semen of a total of 60 subjects:25 minutes. 2. An average liquefaction time of semen according to sperm count: I) Normospermia group(20 cases) :34 minutes. 2) Oligospermia group(20 cases) :21 minutes. 3) Azoospermia group(20 cases) :20 minutes. An average liquefaction time of semen according to abstinence period: I) Less than 3 days group(20 cases) :22 minutes. 2) More then 5 days group(30 cases) :28 minutes. In conclusion: I. The liquefaction time of semen of the normospermia group is longer than oligospermia group or azoosermia group. 2. The liquefaction time of semen may not be greatly influenced by the various factors such as abstinence period. semen volume, semen pH. age of the subjects and so on. In routine semen analyses, it is recommended to begin the analysis at least 25 minutes after the ejaculation. 4. Further studies are required in conjunction with practical application of liquefaction mechanism in infertility and fertility control.

Catheter-related infections (CRIs) are one of the most frequent healthcare-associated infections and are costly, morbid, and potentially lethal. A series of studies has confirmed that a comprehensive bundle approach based on known guidelines was successful in reducing catheter-related bloodstream infections in intensive care units. In this review, I'll summarize the previous recommendations made in 2002 on preventing CRIs and highlight recent advances and the evidences supporting novel methods of CRIs prevention published in research articles.
