The status of DNA synthesis and the effect of UV radiation on the DNA synthesis were studied in mouse skin by microautoradiography. Mice exposed to 100mJ/cm of UVB were injected intradermally with tritiated thymidine, 5 minutes, 2, 6 and 24 hours after irradiation and biopsies were processed for light microscopic autoradiography, A total of 25 ICR female albino haired mice were used as subjects. We compared heavily labeled cells(>10 grains/nucleus) and sparsely labeled cells (3-10 grains/nucleus) in UVL irradiated skin with nonirradiated control skin. 1. Within 5 minutes after UVL exposure an apparent depression in the number of heavily labeled cells occurred. This reduction was statistically significant and remained so for at least six hours post,irradiation. By 24 hours after UVL exposure, the reduction was recovered to nearly control level. 2. By five minutes after UVL exposure, sparsely labeled cells were observed in basal cell layer and differentiated cell layer. The nurriber of sparsely labeled cells appeared highest at five minutes after UVL exposure and then tended to fall to nearly control level at 24 hours. This aberrant type of TdR H incorporation is thought to represent unscheduled DNA synthesis to repair pyrimidine dimers formed in UVL injured DNA molecules,

In the abstract, case description and figure 2, the nomenclature of two mutations was misprinted because of misreading the cDNA nucleotide sequences.

Polydactyly is one of the most common congenital anomalies of the foot, but there are few papers on polydactyly of the foot reported in Korea. Forty-six supernummerary toes in thirty-semen patients were operated at Department of Plastic and Reconstructive Surgery, Korea University Guro Hospital, from May 1985 to May 1995. A clinical review was performed on these cases and the results were as follows : 1. Of the 37 patients, the proportion of unilateral involvement to bilateral was 28(76%) to 9 (24%). 2. Of the 46 toes, postaxial type was a majority involving 35 toes(76%) followed by the preaxial type 7 (15%) and central type 4(9%). 3. In anatomical pattern, Wassel's type IV and Stelling and Turek's type II were the most common ones in 7 toes of preaxial type and 39 toes of central and postaxial types. 4. The excellent results could be made by individualized reconstructive methods performed before walking age.

BACKGROUND: We studied the incidence of trauma caused by alcohol related accidents, and the effects that has on the occurrence, the extent, and the outcome to the patient. METHODS: In our study we studied trauma patients excluding pediatric patients(15 years old and under) who came to the Emergency department of Korea University Medical School Anam Hospital from the 1st of january 1996 to 30th of June 1996, looked into their medical records, and studied the records in a retrospective manner. The trauma patients were divided into two groups, a) alcohol-related and b) alcohol-non-related. The two groups were then subdivided according to their sex, age, the time they came in, the anatomical part of the trauma, the mechanism of their injury, the extent of the injury, the length of their hospital stay, the length of their ED stay and were seperately compared and analysed. Statistically, ANOVA and logistic regression analysis using SAS were used in the study and then was assessed in Chi-square analysis methods. RESULTS: The total of the trauma patients, added up to 832 people, 577: male and 255: female. Among this sum, 16 trauma patients were alcohol related(male:127 & female 36). 115 people were in the age group of 21-40. Compared to the non-alcohol related trauma group, the alcohol-related group had more facial & scalp injuries and tended to come in the hours between 0-6 AM. The cause of the injuries were mossy by fast-fighting and suicide, compared to mostly accidental-slipping injuries in the non alcohol-related group. There were no difference in the degree of the injury(ISS) and the length of hospital stay between the two groups, whereas the length of the stay at the ED was longer alcohol-related trauma patients. CONCLUSION: Alcohol related trauma patients were mostly in their 20s and 30s, came to the hospital at a late time it the reason for their visit were mossy because of fist fighting. In the Emergency department, because prompt and correct diagnosis is quite difficult to make in this group, their ED stay tended to be longer. We can conclude that measuring the blood alcohol level of these patients, continuing the psychological therapy and educating people is needed.
