한국의 크로이츠펠트 야콥병 발생 현황 및 관리정책 개발

Purpose : Through the understanding of the current status of transmissible spongiform encephalopathy(TSE), this study was conducted to contribute to the development of policy and strategy for the control of TSE in Korea in order to keep Korea as a bovine spongiform encephalopathy(BSE)- and variant Creutzfeldt-Jakob disease(vCJD)-free country. BSE and vCJD cases have not been found in Korea. During 2001-2004, the number of patients who have been diagnosed as a definite or probable CJD was 121, which are consisted of 62 male and 59 female(average age: 63 years old). The occurrence of the patients was 5-59 people per year until 2003 and has been gradually increasing due to the recent increase in the diagnostic rate rather than the increase of the incidence. In 2004, the annual occurrence of sporadic CJD(sCJD) in Korea was 1 people per million, which is similar to the average occurrence rate of the world. Two cases of chronic wasting disease(CWD) in deer were found in Chungcheongbuk-do, one in August 2001 and one in October 2001. After that, 4 more CWD-affected deer have been reported in Kyungsangnam-do area in November 2004. We have also examined the possibility that Korean CJD occurred as a result of dietary exposure to BSE. Fortunately, all of Korean CJD patients were not vCJD cases. However, if BSE occurs in Korea, there is a great potential for most of the Korean population to be easily infected with BSE due to their highly susceptible genotype to BSE infection as well as their traditional food habit. In 2003, the total number of people who left Korea was almost identical with the total number of people who entered Korea. However, we could not analyze the number of people who visited or stayed in the UK and Europe during I980s~1990s, in whieh BSE was prevalent in Europe, because there was no statistical data available.

한우육의 육색 안정성과 지방산화에 미치는 환원력의 영향
김용선,김주용,이성기,양부근,양성운 한국동물자원과학회 2001 한국축산학회지 Vol.43 No.3
The effects of reducing ability on meat color stability and lipid oxidation in M. Longissimus and M. Semimembranosus of Hanwoo(Korean native cattle) beef were investigated. Samples were held 8 days at 1℃ and 90% RH, and then meat quality characteristics of Hanwoo beef were evaluated. Also, stability of meat color, myoglobin forms(%), lipid oxidation and reducing ability after a rapid denaturation test(30℃ during 5h) were investigated. CIE a*(redness), b*(yellowness), chroma(C*) values, oxymyoglobin and R630-R580 were significantly(p$lt;0.05) decreased during storage at 1℃ for two beef muscles. Also, reducing ability was significantly(p$lt;0.05) decreased during storage at 1℃and after a rapid denaturation test, then reducing ability had very poor stability. Two beef muscles after a rapid denaturation test had good color stability. Reducing ability negatively correlated with L* value, metmyoglobin(%), TBARS and POV, and positively correlated with a* and chroma values. Consequently, reducing ability of muscle is related to meat color stability and lipid oxidation.
