A preliminary survey of Sarcocystis species in the slaughtered cattle in Cheju was undertaken during May through October 1989, using digested diagnostic technique for the heart, the esophagus and the dorsal muscles of the neck specimens digested in 0.5% trypsin solution. The results obtained were summarized as follows. 1. The overall infection rate of Sarcocystis in a total of 218 slaughtered cattle was as high as 36.7% with the highest frequencies in the esophagus muscles(21. 6%), followed by in the dorsal muscles of the neck(19.1%) and in the heart rnuscles(17.9%). 2. Age difference was noticed as 64.3% in the cattle older than five years in comparison with 41.7%, 34.4%, in the group of two to four years and in the group of younger than two years respectively. 3. It was also noticed that the prevalence in the Brahman cross breed was higher(40.0%) than in any other breeds. 4. Regional distribution of Sarcocystis infections was observed as 75.0% in south-east area, 50.0% 44.7%, 35.0%, 32.0% and 20.6% in the areas of Seogwipo city, north-west, south-west, Cheju city and northeast area respectively. 5. According to the type of rearing the infection rate in the ranch type farm was noticed with and in the stock farms(36.2%).

This survey was carried out to investigate the fatality of the newborn beef calves in three ranches in Cheju area. The results were summarized as follows: 1. The fatality rate was 5.8%(67 calves) from the total 1,160 calves examined. 2. There were pneumonia(46%), enteritis(16%), suckling disorder(13%), theileriasis (4%). and hypomagnesemia(4%) in dead calves. 3. Most of dead calves(78%) with 52cases died within 30days postparturition. 4. Bacteria-induced fatal diseases in newborn calves within 30 days postparturition might be closely associated with maternal immunity by the lack of immunoglobalin of strum.

The .present study was carried out to investigate the incidence of bovine brucellsis in Cheju do during the period from 1985 to 1990. The results were summarized as follows. 1. In the total 239,238 cattles tested. 1180(0.49%) were positive by standard tube agglutination test during the period from 1985 to 1990. 2. The major causes of incidence on brucellosis was grazing with carriers and repeated incidence in a herd. 3. The 13 Brucella abortus biotype 1 isolated from 10(50%) of 20 cattles slaughtered on brucellosis in 1990.

A survey on bovine mastitis in the dairy cattle in Cheju City and Bukcheju County was carried out for a total of 1,731 quarters of 443 heads using the California Mastitis Test in the field. The trials for the isolation of the etiological agents and for the sensitivity tests for antibiotics were also carried out. The overall infection rate was recognized as high as 87.5% in farms, 36.6% in individual cows and 16.7% in quarters. However the rate was regarded as low comparing that in mainland Korea, and the control methodology was discussed.

Chuzan disease of which the main clinical abnormalities were impairment of mobility and nervous signs took place in a calf breeding farm in Cheju province during the period of March, 1993. The serological survey indicated that antibody to Chuzan virus was present at a high rate in Cheju province, while it was at a low rate in the Honam area of the mainland. The retrospective sero-epidemiological investigations strongly suggested that Chuzan virus comes to Korea from the Southeast Asian countries and the first outbreak of Korea is simultaneous with that of Japan. A preliminary study for development of an inactivated Chuzan virus vaccine was performed. The binary ethylenimine treated-tissue culture fluid with a gel adjuvant had good immunogenicity in cattle. To control this disease in Korea, an inactivated Chuzan virus vaccine is scheduled for practical use in the field in the near future.
정상신생아에 있어서 출생후 첫 42시간 동안의 체온 변화에 관한 고찰

A newborn infant is at a disadvantage in maintaining body temperature chiefly because of a large surface to volume ratio and relatively little insulating subcutaneous tissue. Frequently soon after birth the infants skin becomes pale or blue, and the body temperature falls, often several degrees below the intrauterine temperature. Therefore the author designed this study to explore the changes of body temperature in normal newborn infants. Sixty four cases of newborn infants delivered at Chosun university hospital from February to August 1988 were participated in this study. The author had measured body temperatures at birth, after 2,4,6 hours and 6 hours interval for the first 42 hours. And also, comparative study of body temperature and stabilization time between rectal temperature and axillary temperature was done. The results were summarized as follows: 1) At birth, mean ????? temperature was 3.12℃±0.36 and mean axillary temperature was 35.84℃±0.29 2) The mean rectal and axillary temperature were increased to 36.81℃ and 36.70℃ during first 30hours of life respectively, and then no significan changes were seen. 3) The mean difference between rectal temperature and axillary temperature was 0.15℃. 4) Mean of stabilization time of rectal temperature was 2.04 minutes and axillary temperature was 3.93 minutes.
