血清肝炎の予防に関する研究 第2篇 肝炎既往者血液の安全性

Of 137 blood recipients from the blood donors with a history of infectious hepatitis, 61 recipients were examined in terms of liver function tests for more than 3 months. The results obtained were as follows: 1. There was no incidence of serum hepatitis except 2 cases in the recipients who received blood from the donors who had been suffered from hepatitis before 1956. 2. Out of 29 cases, 9 cases including 4 cases icteric serum hepatitis were proved to be the subjects received blood from the donors with a history of hepatitis after 1957. Comparing with the incidence rate of serum hepatitis by the blood transfusion from the voluntary donors for a same period. The above mentioned rate is notably high, and this is almost equal to the rate of the incidence in the cases received blood from paid donors. 3. The incubation prid was within 30 days in 7 out of 11 cases with serum hepatitis. 4. The mixture of blood from the subjects with a history of viral hepatitis was found to be only one or two units, therefore the incidence of serum hepatitis was not increased with the amount of transfused blood. 5. The residential areas of the donors were in close association with the epidemic areas of infectious hepatitis. 6. Consequetly, it is concluded that those donors who have a history of hepatitis for the past 10 years and who have residence in the epidemic areas, should be eliminated from the choice of the blood donors.
