本文报导加拿大多伦多地区63名无症状给血者的乙型肝炎抗原亚型及其肝脏异常调查结果。38名(60%)有亚型抗原决定素d,25名(40%)有亚型决定素 y。大部分 adw 亚型给血者出生于加拿大、中国、德国和西印度群岛,而大多数 ayw 给血者来自地中海的国家。8名 adr 给血者全都来自中国。因此乙型肝炎抗原慢性携带者的亚型来源,舆其说同居住国有关,倒不如说同出生国籍的关系更为密切。几乎所有 adw、adr、和 ayw 群(分别为30%、25%和26%)都有明显的肝功能异常,主要是血清谷丙转氨酶增高和肝活组织检查不正常。14名亲属也分离到亚型,并舆家属给血者同属一亚型。
This article reports on hepatitis B antigen subtypes and their liver abnormalities in 63 asymptomatic donors in Toronto, Canada. Thirty-eight (60%) had sub-determinant d and 25 (40%) had subtype determinant y. Most adw subtype blood donors were born in Canada, China, Germany and the West Indies, while most ayw donors came from countries in the Mediterranean. Eight adr to the blood all from China. Therefore, the subtype of chronic carriers of hepatitis B antigen, it is said that cohabitation with the country, might as well be more closely related to the birth of the nationality. Almost all of the adw, adr, and ayw groups (30%, 25%, and 26%, respectively) had significant liver dysfunction, mainly elevated serum alanine aminotransferase and abnormal liver biopsy. 14 relatives also separated into subtypes, and the family members to the blood belong to the same subtype.
