무한경쟁속 치열한 경쟁에서 이기고 생산성을 높이기 위해서 품질관리의 중요성이 강조되고 있는 가운데 최근 품질관리 전문가시스템에 관한 연구논문을 발표해 주목을 끌고 있는 김성인 교수를 만나보았다.
간환자의 혈청 HBsAg 검사 결과와 간조직의 Orcein 염색결과 비교 연구
김성인 김천대학교 1999 김천대학교 논문집 Vol.20 No.-
The purpose of this study is to show that the staining mechanism and specificity of Orcein stain for HBsAg in human liver tissue. The results of Orcein stain in 128 cases of liver needle biopsy tissue were compared with the results of serum HBV releated antigen and antibodies. Using anti-HBsAg mouse IgG, immunohistochemical stain were prepared and the results were used for demonstration of presence of HBsAg in liver cells. The experiments yielded the following results: 1. Hepatitis were 63.3% of total liver diseases and 85.9% of liver disease were involved with the hepatitis B virus. 2. The positive rate of Orcein stain was 56.8% of serum HBsAg positive cases, but all serum HBsAg negative cases were obtained negative results of Orcein stain. It may be suggested that Orecin stain has a very high specificity for HBsAg. 3. There were 10~20% negative result of immunohistochemical stain although serum HBsAg tests were positive. 4. It was suggested that HBsAg titer was main element of Orcein stain. Because first group with HBsAg high toter were showed all positive results of Orcein and immunohistochemical stain.
