PURPOSE: We collected the data of Science Citation Index (SCI) and SCI Expended (SCIE) papers written by the members of the Korean Society of Radiation Oncology (KOSRO) to analyze the current status and the future trend. MATERIALS AND METHODS: We searched the database of SCIE for the period from 1981 to 2011 at the Web of Knowledge site. Articles, reviews or proceedings written by KOSRO members as the first or corresponding authors were included. Search terms were the following combination of subject headings: therapeut radiol, radiat oncol, Korea. For National Cancer Center, combined search terms such as natl canc ctr, Korea and the names of faculties were applied. RESULTS: The total number of SCIE papers was 547. Numbers of the published papers in 1995, 2000, 2005, and 2010, were increased continuously, which was 2, 14, 40, and 83, respectively. The average impact factor was 2.9. The papers were published at the 134 different journals. The proportion of "International Journal of Radiation Oncology Biology Physics" was 23.4% of all the papers. The number and proportions of papers by subject categories were 87 (15.9%) in biology, 73 (13.3%) in physics and 387 (70.6%) in clinics. The papers of the top five institutions, based on the number of published papers, occupied 66.3%. CONCLUSION: The number of SCIE papers is increasing rapidly in the field of radiation oncology in Korea. To improve the quality of papers, multi-institutional retrospective or prospective randomized studies should be done for the common cancers in Korea.

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.

The bone is the dynamic living tissue which is always maintained bone mineral content by bone resorption and formation. It has been well known that the bone mineral content is decreased very slowly with aging. It is very difficult to diagnose the osteopenia because it is almost subclinical. Another important problem in the osteopenia is the fracture occurring spontaneously. The quantitative method of bone mineral mass provide an information to diagnose the osteopenia and predict the risk of spontaneous fracture. Various methods have been used to access the degree of bone atrophy but have not been routinely available for clinical application in the hospital. The microdensitometric method is a noninvasive, easy, accurate, and objective one to monitor the degree of changes in the skeletal mass quantitatively. So, we measured the 7 indices at the middle site of the 2nd metacarpal bone with a microdensitometer and computer on an X-ray film of the hands and studied the correlations between the age and indices of those under 30 and over 30 yrs old in healthy and fracture groups. The results were obtained as follows : 1. There was a significant high correlation between age and indices in healthy and fracture groups. 2. The measurement of age by microdensitometric method was highly correlated with the chronological age. 3. Comparing both groups, There was a significant correlation of D (P<0.001), MCI(P<0.01), and d (P<0.01) over 30 yrs in male and GSmin (P<0.001) and ΣGS/D (P<0.01) over 30 yrs in female. 4. In fracture group, 1) The index of bone width(D) was slightly larger than in the healthy group. 2) The metacarpal index(MCI) was lower than in the healthy group. 3) The index of medulla width(d) was wider than in the healthy group. 4) The density index of cortex(GSmax) was smaller than in the healthy group. 5) The density index of cortex and medulla(GSmin) was smaller than in the healthy group. 6) There was no considerable difference in ΣGS/D between healthy and fracture groups. 7) The densitometric pattern was more aggrevated than in the healthy group.

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.

Hepatic masses show different enhancing patterns in N bolus computed tomography: Hepatocellular carcinoma shows high-attenuation in the early enhancing phase and low-attenuation in the late enhancing phase, hemangioma shows peripheral dot-like high-attenuation in the early enhancing phase and central high-attenuation in the late enhancing phase, and metastatic cancer and cholangiocelluar carcinoma show peripheral high-attenuation rim in the early enhancing phase and central portion gradulally high attenuation in the late enhancing phase. but sometimes enhancing patterns of the hepatic masses are confuse. To evaluate the significance of the AFP level and HBsAg in differentiation of the hepatic masses, we retrospectively analyzed AFP level and HBsAg' in 228 pathologically or radiologically confirmed hepatocellular carcinomas, and 137 pathologically nonhepatocellular cacinomas. The results were as follows In hepatocellular carcinoma, AFP level above 20ng/ml was 77.8% and HBsAg positve was 72.6%. In nonhepatocellular carcinoma, AFP level above 20ng/ml was 3.7% and HBsAg positve was 16.1%. We concluded that AFP level and HBsAg are helpful to distinguish hepatocellular carcinoma from nonhepatocellular carcinoma, when IV bolus computed tomogram finding is uncertain.
