    Abstract: 有關染色體斷裂方面,每一案例計算其40個細胞所出現的斷裂數(break perc cell
    -b/c) 。統計出現頻率結果,在以化學藥物Bleomycin 處理前後,各組均有明顯增
    加。正常組為85/526 (增加6.19倍);帶原組為110/1325 (增加12.05 倍);慢性肝炎
    組為48/1526(增加31.79 倍) 。比較之下,帶原組較正常組增加2.519 倍(1325/52
    6); 慢性肝炎組為正常組之2,900 倍(1526/526)。以Mann-Whitney two sample ra
    nk test 和paired t-test 算之,帶原組與正常組之間固無顯著差異(P<0.0061),
    但慢性肝炎組與正常組之間則有統計學上差異(P<0.048) 。可見慢性肝炎組之斷裂
    率有明顯增加,代表其DNA 修復能力甚差,此與其疾病之臨床預後(prognosis) 相
    吻合。亦即因慢性病程中不斷發生和累積的染色體斷裂,使疾病惡化。而感染B 型肝炎後,個體之間是否會呈慢性化.也許與" 體質特異性 "有關。此" 體質特異性"實即染色體基因變化之差異。
