Multiple species of muridae and arvicolidae rodents serve as the natural reserviors of hantaviruses. Hantaviruses are distributed in rodent populations world-widely even in geographical areas where hemorrhagic fever with renal syndrome (HFRS) has not been reported. Serologic diagnosis of infection, using hantaviral antigen, indicates that hantaviruses are wider distributed in wild rodents. This study was designed to intended the hantavirus infection among wild rodents captured in Kyebang mountain, Kangwon-do in Korea. A total of 216 wild rodents in 3 species were trapped in July and September in 1995. Serological evidence for hantaviruses infection were tested against five hantavirus antigens by indirect immunofluorescent antibody technique (IFA). Among 100 Eothenomys regulus, 78 Apodemus peninsulae and 38 Apodemus agrarius (IFA). Among 100 Eothenomys regulus, 78 Apodemus peninsulae and 38 Apodemus agrarius; 12 C. regulus, 15 A. peninsulae and 6 A. agrarius were IF antibody positive against hantaviruses. This data suggest that Eothnomys regulus and Apodemus peninsulae would be a natural reservoir of hantaviruses.

A clinical study was made on 144 cases of urolithiasis among the total number of 562 in-patients during the 5 years from January, 1974 to December, 1978. The results were as follows: 1. The incidence of the patients with urolothiasis was 25.6% of the in-patients and male to female ratio being approximately 2.1:1 2. The age of the patients ranged from 20 to 50 years in approximately 74.5% 3. A seasonal occurrence was highest during summer on 36.8%. 4. The locational distribution of urinary calculi was in the ureter in 5l.4%, kidney in 34.7%. bladder in 9.7% and urethra in 4.2%. 5. The most favored predirection site of ureteral stone was lower third in 60.8% of all cases. 6.

PURPOSE: This study was made to evaluate the clinical characteristics and the treatment of the gangrene of the male genitalia manifested with progressive life threatening disease. MATERIALS AND METHODS: Between June 1992 and December 1998, medical records for patients with Fournier's gangrene were reviewed with respect to age at presentation, associated disease, and clinical course and the treatment. RESULTS: The age of patients ranged from 29 to 92 years. The prodromal sign noted were usually low abdominal and inguinal pain. There were no differences in the causative pathogens compared to those of previous reports. The common underlying diseases were diabetes and chronic liver disease. Hypoalbuminemia and leukocytosis were found in all. Early radical debridement and aggressive antibiotics therapy were performed in all cases. Reconstructive surgery of defected skin was performed 7 to 45 days(mean 33.6) after debridement and period of hospital stay ranged from 14 to 123 days(mean 35.8). The motality rate was 13.3%. CONCLUSIONS: It is thought that the motality rate of Fournier`s gangrene is reduced by early aggresseve debridement of the wound and empirical triple antibiotic therapy, and the comprehension of clinical course is important as well.

OBJECTIVES: The aim of this study was to evaluate the differences in patients with positional dependent sleep apnea according to their non-supine apnea-hypopnea index (AHI, > or =5 vs. <5). METHODS: 92 patients with positional sleep apnea were evaluated. The patients were divided into two groups : group I was non-supine AHI having > or =5 ; group II was non-supine AHI having less than 5. Statistical analysis was performed to find the difference between two groups. RESULTS: In 92 patients, the number of group I patients was 11 (12%) and the number of group II patients was 81 (88%). In the severe AHI group, percentage of group I was dominated (70%) and showing a significant difference compared with the mild and moderate AHI groups (p<.05). In the severe body mass index (BMI) group, percentage of group I was dominated (54.5%) and showing a significant difference compared with of the mild and moderate BMI groups (p<.05). The percentage of group I was significantly higher than group II (p<.05) in the AHI, supine AHI, non-supine AHI and snore time. CONCLUSIONS: In patients with positional sleep apnea, severe OSA and high BMI are more common in patients with non-supine AHI> or =5 than non-supine AHI<5.
