目的 　研究原發(fā)性肝細(xì)胞癌發(fā)生、發(fā)展過(guò)程中肝組織增殖細(xì)胞核抗原（proliferating cell nuclear antigen, PCNA）的動(dòng)態(tài)演變規(guī)律。
方法 　將60只SD大鼠按隨機(jī)數(shù)字表法隨機(jī)分為對(duì)照組（20只）和實(shí)驗(yàn)組（40只）。用化學(xué)致癌劑3,3′-二氨基聯(lián)苯胺（3，3′-diaminobenzidine,DAB）誘發(fā)SD大鼠肝癌，采用免疫組織化學(xué)方法連續(xù)監(jiān)測(cè)各時(shí)相肝組織中PCNA的表達(dá)，光鏡下觀察肝組織的病理變化。
結(jié)果 　本實(shí)驗(yàn)的誘癌過(guò)程可分為炎性變期、增生纖維化期和癌變期3個(gè)階段； PCNA的表達(dá)最早出現(xiàn)于炎性變?cè)缙趨R管區(qū)的卵圓細(xì)胞中，并在匯管區(qū)呈區(qū)域性過(guò)表達(dá)分布； 炎性變中期，PCNA表達(dá)陽(yáng)性率達(dá)高峰，隨后下降，在癌變期又升高，在整個(gè)病理演變過(guò)程中其表達(dá)具波動(dòng)性。
結(jié)論 　在致癌因素的存在下，PCNA首先表達(dá)于卵圓細(xì)胞； PCNA表達(dá)的動(dòng)態(tài)演變對(duì)肝癌的發(fā)生有一定的預(yù)警作用。
