Hepatitis B Virus(t-IBV) infection is one of the major health problems in Korea and HBsAg positive rate was known to be as 6-10% in general population. This study was carried out to determine HBV infection rate of workers who worked in one company and to assess the conversion rate of HBV markers(HBsAg: by RPHA method, Anti-HBs: PHA method) from 1990 to 1992. A total number of study subject was 1,972 male workers who were interviewed during health check up at 1992. Healthy workers were defined those who have none of the past histories of transfusion, hepatitis, abnormal liver function. The results were as follows: 1. HBsAg positive rate among healthy workers in 1990 was 2.7% and it was highest in age group thirties as 3.0% with no statistically significance by age group. 2. HBsAg positive conversion rate was 3.0% and negative conversion rate was 7.7% from 1990 to 1992. 3. The rate of Anti-HBs formation was 32.5% after 3 doeses hepatitis B vaccination.

Interleukin 1(IL-1), a 17.5 KD glycoprotein, is known to be associated with local bone resorption. In the present study, we examined the effects of IL-1, compared with insulin and parathyroid hormone (PTH), on DNA, protein and collagen synthesis in UMR-106-01 rat osteoblastic osteosarcoma cells. When 200 units/mL IL-1 was administered to UMR-106-01 cells, [3H]-thymidine uptake increased to 119% of the untreated control. But when 10 nM insulin was added to the cells, [3H]- thymidine uptake increased to 130% and when 1 nM PTH was added, the uptake decreased to 89% of the control. On the other hand, protein and collagen synthesis, measured by [3H]-leucine and [3H]-proline incorporation respectively, were not affected by IL-1 administration compared to the other hormones. These results indicate that IL-1 effects osteoblast-like cells, stimulating DNA synthesis via a different mechanism to the well-known cell growth factor, insulin.
