Ninety two injuries of the main nerves in the upper extremity observed in 79 patients, were studied at the Department of the Orthopedic Surgery, 17th Army Hospital from May 1965 to Aug. 1968. The treatment given consisted of neurolysis in 15, neurorrhapy in 77(primary 43 and secondary 34) and tendon transplantation and transfer in 11 cases. The results for the median, ulnar and radial nerves after primary and secondary suture were analyzed with respect to the level of injury(high and lower). The results of the median nerve repair were more succesful than those of the ulnar nerve, In these two nerve injuries, the sensory recovery was better than the motor and secondary suture gave better results than primary suture. Thirteen cases failed to respond to primary or secondary nerve repair, among those tendon transfer or tendon transplantation was tried in eleven cases, from the latter approximately 25% of motor recovery could be seen.

Tentative diagnosis of meniscal pathology is very helpful for the successful operative management including arthroscopy. Conventional arthrography has long been used to meet this purpose, but it has some limitations due to complex views and some difficulties in imaging the whole anatomical structures. Recent diagnostic advancement produced post-arthrographic HRCT and MRI for the compensation of these problems of conventional arthrography. Arthrography and post-arthrographic HRCT has been carried out on 49 knees in 43 patients. 38 knees among them could be confirmed by arthroscopy and following results were obtained. 1. Diagnostic accuracies of post-arthrographic HRCT for medial and lateral meniscal injuries of knee were 94.7% and 92.1% repectively. 2. Shape, contour of torn meniscus and the relationships between the torn fragments were better demonstrated with HRCT. 3. Horizontal tear could also be suspected by HRCT. 4. Peripheral detachment could be differentiated with synovial recess on the HRCT, especially in the reformat view, but was more clearly visible in arthrography. 5. Arthrography and HRCT can be used as a good complementary study for the evaluation of meniscal injuries.

Allogenic peripheral blood stem cell transplantation could be used instead of allogenic bone marrow in treatment of leukemia in children. This 10-year-old female patient with high-risk acute lymphoblastic leukemia received a myeloablative regimen followed by allogenic peripheral blood stem cell transplantation from an HI A-identical sibling donor. Neutrophil recovery to greater than 500/pL occurred at day 11 and platelets recovered to greater than 20,000/pL at day 13. Allogenic peripheral blood stem cell transplantation can be performed safely and may result in a rapid neutrophil and platelet engraftment, without any apparent increased risk of acute graft versus host disease.

The purpose of this study was to compare the difference of two survey methods for health services research. Data were collected by means of two types of household survey conducted from March 11 to September 19, 1985. A probability sample of 30,613 persons was taken from 180 Enumerated Districts designated by the Economic Planning Board. The sample was divided into two groups systematically. One group was surveyed by the self-administered questionnaire and the other group was interviewed. Response rates were 81.4% and 90.6% respectively. The data were analyzed by the ratio of the results of the self-administered survey to those of the interview survey. No difference was observed in sex, age, residence, or occupation between the two groups. However the respondents' characteristics were statistically different between the two groups. The major findings of this study are as follows : 1. The morbidity rate was 142.5 per 1,000 persons during the two week period by the self-administered questionnaire survey and 74.3 per 1,000 persons with the interview survey method. The ratio of the morbidity rate by the self-administered questionnaire to that by the interview was 1.92, and the difference between the two rates were due to the personal characteristics. 2. The out-patient utilization rate was 10.2 visits per person per year by the self-administered questionnaire survey and 5.4 by the interview survey, and the ratio was 1.89; the admission rate was 3.2 times per 100 persons per year by the self-administered questionnaire survey and 1.9 times by the interview survey, and the ratio was 1.68. Differences due to the sociodemographic characteristics were greater in the out-patient utilization rates than in the admission rates. 3. Percentages of effective medical care demand were 90.2% in the self-administered survey and 92.3% in the interview survey; the ratio was 0.98 which was less than that of the morbidity rate and medical care utilization. But, differences of effective medical care demand occurred in persons with no occupation, and aged or low educated respondents. 4. Respiratory illness had the highest frequency in the two survey methods. But there was a slight difference between the two survey methods in morbidity composition. 5. It was concluded that data collected by the interview survey were inclined to be underestimated and this problem can be corrected by a modified self-administered survey.

This study was performed in a rural community, Kanghwa county which was introduced to a regional medical insurance pilot program in 1982. The purposes of this study were, firstly, to observe the changes in ambulatory care utilization in the three years 1982, 1983 and 1987 ; secondly, to analyse factors which convert perceived medical care needs to effective medical care demand. During the three periods, a serial interview survey was performed to determine the changes in medical utilization before and after the regional medical insurance program implementation. The number of subjects was 3,356 persons in the year 1982, 3,705 in 1983 and 2,745 in 1987. The results of the study were as follows : 1. Total ambulatory care utilization rates per 100 persons during a 2-week period were 23.6 in the year 1982, 21.8 in 1983, and 29.3 in 1987 ; and physician visit rates were 6.1 in 1982, 11.7 in 1983, and 14.9 in 1987. Thus, compared to the total utilization rate there was a definite increase in physician visit, and during the study periods there was a decrease in drug stores visits whereas an increase in hospital or clinic visits was noticed. 2. The rates of effective demand for medical care need were 70.7% in 1982, 70.5% in 1983 and 75.9% in 1987 ; and the rates of patients who visited physicians were 20.2% in 1982, 42.8% in 1983 and 35.6% in 1987. Thus, physician visits increased sharply by introducing the medical insurance program, but after the latent medical care demands were fulfilled, there was a slight decrease in the physician visits. 3. The number of acute symptoms and the number of chronic symptoms were common determinants of total ambulatory care utilization and physician visits. Besides the medical care need factors, age in 1982, sex and accessibility in 1983, and accessibility in 1987 were statistically significant determinants of the total utilization ; sex and accessibility in 1983, and education in 1987 were also statistically significant determinants of the physician visit. 4. For persons with perceived acute symptoms during the 2-week periods, accessibility in total utilization and age in physician visits were common discriminating factors of ambulatory care utilization in the three years, and education and income were also statistically significant variables For persons with perceived chronic symptoms, occupation and income were statistically significant discriminating variables commonly observed in total utilization and physician visits.

Island regions suffer from a shortage of health care in part because they are less developed, they cover a widespread area relative to the population, and due to transportation barriers. The purpose of this study was to assess the level of illness and the magnitude of medical care utilization, and to investigate the determinants of utilization in these area. The data were collected by means of a household survey conducted from February 16 to 25, 1987 on 5 islands which were selected in consideration of the size of the population, the distance from the main land, and the distribution of health care facilities. The household response rate was 89.1% (491 of 551 households), and 1971 persons were surveyed. The major findings of this study are as follows: 1) The morbidity rate of the island inhabitants was 27.7% during the two weeks, and 25.5 chronic illnesses and 9.1 acute illnesses per 100 persons, were noted. Differences in the magnitude of illness were statistically significant by sex, age, education, and family size. 2) The magnitude of total ambulatory care utilization was 16.8 visits per 100 persons during the two weeks, which was less than that of other regions; and differences in the magnitude of total ambulatory care were statistically significant by sex, age, education, occupation, and family size. 3) Unmet needs were classified as 56.0% in chronic illnesses and 19.6% in acute illnesses; and differences in unmet needs were statistically significant by sex, age, education, occupation, income, and family size. 4) Statistically significant determinants in medical care utilization included the frequency of acute illness and chronic illness, and income in total utilization; the frequency of chronic illness and acute illness, and medical care insurance in physician visits. 5) According to the results of the path analysis, need factors had the greatest effect on utilization, and predisposing factors had more indirect effects through enabling or need factors than direct effects.

Journal of the Korean Pediatric Society 2001;44(1):68-74
PURPOSE: Interleukin(IL)-16 is a potent chemoattractant factor for CD4+ T cells, monocytes, and eosinophils. It up-regulates IL-2R on CD4+ T lymphocytes and regulates the function of antigen presenting cells. We used retrovirus-mediated gene transfer of the human IL-16 gene into the neuro-2a cells, which is the murine neuroblastoma cell lines, to investigate whether locally secreted IL-16 might generate anti-tumor immune responses. METHODS: We estimated whether the local secretion of IL-16 from the genetically-modified tumor cells would affect their tumorigenicity in vivo, and then, IL-16 transfected neuroblastoma cells would protect mice from tumor development after wild-type tumor cell challenges. And we investigated the mechanism of IL-16 by nude mice trial of an anti-tumor immune response. RESULTS: The IL-16 gene-transduced neuro-2a clones secreted 4.2-6.0ng of IL-16 per mL per 10(5) cells during 24 hr. None of the mice(N=6) injected with 2x10(6) of irradiated, IL-16 gene-transfected neuro-2a cells developed tumors within 6 weeks while all of the mice(N=6) injected with wild-type neuro-2a cells developed tumors. Immunization of mice(N=6) with 2x106 IL-16 gene- transfected, irradiated neuro-2a cells protected these animals against a subsequent challenge with 2x10(6) wild-type tumor cells. Nude mice also showed an anti-tumorigenicity effect. However, the mice did not reveal the prophylactic effect against murine neuroblastoma. CONCLUSION: The local secretion of IL-16 gene-transduced tumor cells abrogated their tumorigenicity and induced protective immunity.
