Todays, remnant split-thickness skin graft is stored for graft failure or for delayed grafting. Refrigerated skin is usually stored for 3 weeks, after which, cellular respiration ceaces. Even though the refrigerated skin can be used before 3 weeks after harvest, the success rate of the skin graft is usually lower than in case of fresh skin. One of the most reliable explanations is multiplication of microorganisms on the stored skin, that is, the more microorganisms on the refrigerated skin, the less the success rate of grafts. For this reasons, some kind of antibiotics have been used for storage of the split-thickness skin piece. But there is no report about the effect of antibiotics on stored skin. We want to know the effect of the antibiotics on stored skin. For this purpose, we did three experiments for qualititative bacteriology of refrigerated skin. Experiment 1 was qualititative identification of microorganisms colonizing split-thickness skin after 2 weeks storage in low temperature, and sensitivity tests for identified microorganisms. On the basis of experiment 1, the proper antibiotics were selected and samples of split-thickness skin were stored using this antibiotics. At 2 weeks after storage in low temperature, samples of split-thickness skin were cultured for identification of bacterial growth. This is experiment 2. Experiment 3 is histologic examination of the split-thickness skin involved in experiment 1 and 2.In the experiment 1, we found five kinds of microorganisms in 9 out of 30 split-thickness skin samples. The most common microorganism was coagulase negative Staphylococcus which was found in 4 samples. Through the antibiotics sensitivity test, teicoplanin was selected as the most proper antibiotics. In experiment 2, we could not find any microorganisms in 30 split-thickness skin samples. In experiment 3, there were no histologic differences in the split-thickness skin samples whether antibiotics were used or not. Through these results, we have confirms that split-thickness skin pieces are more safely stored using proper antibiotics.

To survey the seroprevalence of hepatit!s B virus(HBV) in relation to serologic tests for syphilis(STS), using VDRL and TPHA test, the tests were done in the seri of 1252 institutionalized persons, who lived in Taegu Hope Village for the poor or crippled, and 1831 controls, who had the regular routine physical examination from March to May, 1987. The positive rates nf HBsAg and anti-HBs were 11.7%(146) and 27.0%(338'). compared with 6.25%(ll) and 18.4%(337) in controls, respectively. The prevalence of HBV including HBsAg and anti-HBs was higher in institutionalized persons (38,7+i) than in controls(24.6%)(p<0.0001). The positive rate of STS was higher in institutionalized persons(7.5%) than in controls(2.9%)(p<0.0001). There was a tvend for a higher rate of seropositivity in women than in men of institution- alized persons in the both diseases. The prevalence of HBV among STS-positive cases wa.s 42.6%(40) of instituti- onalized persons and 26.4%(14) of controls, but not, statistically significant, the gre,ater part of them distributing in 4th and 5th decades. The positive rates of I-tBi.Ag in institutionalized persons was 45.5%(5) of STS-positive cases and 25. 9%,'35) of STS-negative cases. No correlation was found between the serologic ma kers of HBV and VDRL titration.

Bacteriological index(BI) was calculated by slit-skin smears taken from the earlobe and the dorsal surfaces of the proximal phalanges of the index finger and of the great toe in 110 lepromatous leprosy patients who have been treated regularly by antileprosy chemotherapy. The bacteriaI indices from the three sites were compared, and the results were as follows. 1) Sixteen patients whose BI of the earlobe smear was 4. 0 in average shawed the highest degree of positivity of M. leprae in the smears taken from the finger and the great toe. 2) ln seventy-four patients whose BI of the earlobe smear was l. 0 or higher, eight (10.8%) showed higher BI in smears taken from both the finger and the great toe, fifteen (20. 3%) and twenty-seven(36. 5%) showed approximately the same BI in smears taken from the finger and the great toe, respectively, 3) In thirty-six patients whose BI of the earlobe smear was negative, twelve (33. 3%) showed higher BI in smears taken from both the finger and the great toe. 4) The mean value of BI of the three sites was 3.7 in the earlobe, 3. 2 in the finger and 3. 0 in the great toe. Comparing the BI of the three sites, the finger and the great toe were found to have comparable BI with the earlobe, although the BI of the earlobe was highest. The authors concluded that it was quite reasonable to include the finger and the great toe in slit-skin smears for M. leprae identification, particularly when the BI of the earlobe was negative. A follow-up investigation seems mandatory.

The occurrence of a lipoma-like condition associated with trauma would tend to be regarded as a subset of or a separate entity from ordinary lipoma. We report herein a case of traumatic Lpoma occuring on the dorsum of the left hand. The patient was a 46-year-old male, who had struck his left hand against a window about two months previously and noted casually an asymptomatic, firm, dermal lesion at the site of injury. On gross examination, the enucleated nodule was a smooth-surfaced, yellow fatty mass measuring 0.3 × 0.5 × 0.3cm which looked like a kernel of corn. Microscopic examination revealed encapsulated mature fat consistent with lipoma.

Soft tissue coverage of heel defects has long been a difficult problem. In 1982, Iron reported eight cases of heel defects in children using an ipsilateral posterior thigh flap with use of the Hoff-man's skeletal fixation apparatus for immobilization. We report three cases of heel defects treatment in children using ipsilateral posterior thigh flap and detach flap in an average 13 days with aid of single photon emission computed tomography(SPECT) for evaluation of circulation status of flap.
