由于病毒学和血清学的进展,将病毒性肝炎划分为甲型、乙型和非甲非乙型(Non—A Non—B Hepatitis,简称NANBH);Garral等报导成人散在肝炎中有20—25％。输血后肝炎的90—95％是NANBH;已知输血后NANBH可慢性化及呈慢性携带状态。一、病原学的研究:1978年用黑猩猩作NANBH感染动物试验成功。当时研究者有两组,一组以Alter及Purcell为首,另一组以Tacor及Gerety为首,各自用获得肝炎病人和以前其血液里己传染NANBH于他人
Due to advances in virology and serology, viral hepatitis is classified as non-A Non-B Hepatitis (NANBH); Garral et al. Report 20-25 %. 90-95% of hepatitis B after transfusion is NANBH; NANBH is known to be chronic and chronic in transit after transfusion. First, the etiology of the study: 1978 chimpanzees for NANBH infection animal experiment was successful. At that time, there were two groups of researchers, one headed by Alter and Purcell and the other headed by Tacor and Gerety, each receiving hepatitis B patients and previously infected NANBH in their blood
