In order to understand the epidemiologic characteristics and trends of Leptespirosis in Korea, year book of acute infectious disease and literatures published were thoroughly reviewed. The results obtained are as follows: 1. The outbreak of Leptospirosis in Korea has decreased during recent years. Most of the patients occured in Semptember, October, and November. Seventy nine percent of reported patients occured in north Choongchung, south Choongchung, and Kyunggi province in 1987-1991. 2. Leptospires isolation rates were ranged from 0.2% to 16.0% among normal healthy person, higher in rural residents than military personnels. 3. Total of 92 strains were isolated from human in six years from 1984 to 1990. Its main serogroups were Icterhaemorrhagiae and Canicola, predominantly consisted of serovar lai, copenhageni and canicola. Eighteen strains of Biflexa were also isolated from healthy persons and patients. 4. The proportion of Leptospirosis among patients with acute febrile episode has decreased since 1985. Sero-positive rate of male among patients with acute febrile episode is higher than that of female. Sixty percent of sero-positive patients with acute febrile episode was older than 40-year of age. The seropositive rates were consistently the highest in harvest season than other seasons. Residents of north Choongchung, north Chunlla, south Chunlla, Kyunggi, and north Choongchung provinces showed higher seropositive rates than those of other ones. Main serogroups positive to most sera of Koreans were Icterohaemorrhagiae and Canicola. 5. The sero-positive rate of normal healthy persons ranged from 2.0 to 25. 6% ; the sero-positive rate of rural area was 4 to 8 times higher than that of healthy urban people. Little difference was observed in sero-positive rate by age group among above 40 years old people, although it was higher in male by sex, in farmers by occupation and in some provinces by area.

A clinical review was performed of 11 cases of traumatic foot treated by tendon transfer at Severance Hospital during the period from April 1979 to March 1988 and the results are summarized as follows: l. Among 11 patient, there were 8 males and 3 females, ranging from 4 to 36 years of age. 2. Anterior tibial tendon was used in 6 cases, among these, split anterior tibial tendon was used in 3 cases. Posterior tibial tendon was used in 2 cases and extensor digitorum longus tendon of the foot in 3 cases. 3. In cases of soft tissue injury where tendon transfer was impossible, microvascular free cutaneous flap transplantation was combined with the tendon transfer in 6 cases. 4. Follow-up results of the 11 cases were obtained from 5 months to 9 years. Excellent results were obtained in 8 cases and satisfactory in 3 cases. For the correction of function loss in traumatic foot, tendon transfers were useful method for the recovery of active motion of the foot.

Recently, the incidence of pelvic bone fractures has been increased with increment of the volume of traffic. We reviewed 318 cases of pelvic bone fractures treated at the department of orthopaedic surgery of Hanyang University Hospital during the period from May, 1972 to December, 1980. The age and sex distribution, cause and classification of fractures, type of treatment, associated injuries and complications were recorded and investigated. The results obtained were as follows: 1. There were one hundred and ninety four (61%) male and one hundred and twenty four (39%) female, and one hundred and ninety seven patients (62%) in this entire series were aged from twenties to forties. The most common victims were in active persons. 2. The most common causative injury was traffic accident. 3. Two hundreds and thirteen (67%) cases were stable fracture and one hundred and five (33%) cases were unstable fracture, which were classified by Kanes classification. 4. The fracture of the femur was most commonly associated bone and joint injuries and the injury of the lower urinary tract was also most commonly associated soft tissue injuries. 5. All of the cases, except 3 cases of the avulsion fracture, were treated with conservative treatment. The remaining 3 cases were treated with surgical treatment, 6. The mortality rate was 5.3%, and the most common cause of death was hemorrhagic shock in 70.6% of the entire fatal cases in this series.

OBJECTIVES: To explore the possible effect of an interaction between summertime heat waves and ozone on cardiopulmonary mortality during the 1994 heat wave in Korea. METHODS: The unusually hot summer of 1994 in Korea was defined as the heat wave in this study. We examined the associations of air pollutants with daily cardiopulmonary deaths between 1991-1995, considering the product term of the heat wave and each pollutant, weather and time trends. RESULTS: During the heat wave, while temperatures were uniformly higher than those of other summers, the within-heat-wave difference in mortality paralleled that in the regional ozone levels. In terms of the influence of the heat wave, the results of ozone were different to those of total suspended particles (TSP) and sulfur dioxide (SO2). The ozone association (relative risk (RR) =1.036; 95% confidence interval (CI) = 1.018-1.054) was observed only under heat wave conditions, while the TSP (RR =1.006, 95% CI = 0.999-1.012) and the SO2 (RR =1.018, 95% CI = 1.011-1.024) associations were found under normal weather conditions (per interquartile increase of each pollutant; results of three pollutants model). The ozone association under heat wave was attributable to the statistical interaction between the heat wave and ozone. CONCLUSIONS: These results support the possibility of a biological synergy between the heat wave and ozone, one that is not evident between the heat wave and other major pollutants like particles or SO2.

BACKGROUND: It is now well known that oxygen free radicals act as mediators of cellular injury in many cardiovascular diseases. Although some evidences have been presented for an altered number of adrenergic receptors in heart disease, a detailed examination of the interaction of free radicals with cardiac adrenergic receptors has little been carried out. METHODS: This study is therefore undertaken to examine the influences of adrenergic blocking agents(propranolol, prazosin) and cyclooxygenase inhibitor(aspirin) on the cardiac damage by oxygen free radicals. Ischemic condition of the isolated rat heart was made by Langendorff preparation, and then measured superoxide dismutase(SOD), lactate dehydrogenase(LDH) released in the perfusate, and malondialdhyde(MDA) concentration in the cardiac tissue. RESULTS: We obtained the results that increased SOD activity and tendency of decreased LDH activity by the pretreatment of propranolol, prazosin, and aspirin in cardiac ischemic-reperfusion injury. Those effects were more predominant in adriamycin treated group comparing with not treated group. CONCLUSION: Adrenergic blocking agent, propranolol, prazosin, and aspirin seem to have some protective effect on the reperfusion injury of the heart.
