摘　　要：采用胫骨 X线摄片与病理切片对照的方式 ,检测了鸡骨型白血病 (下称 OP) X线诊断效果 ,即以自然发生和人工诱发的 OP病例为对象 ,作出 X线诊断后 ,选择有代表性的 5 0例分 5组作病理切片对比观察 :OP轻度阳性 (+)组15例 ,中度阳性 (++)组 5例 ,重度阳性 (+++)组 15例 ,OP可疑 (± )组 10例 ,OP阴性 (- )对照组 5例 ,并对一批佝偻病合并 OP病例作了比较。结果 ,OP的 X线 3个阳性组全部有明显组织学病变 ,且轻重程度相一致 ;OP可疑组也有轻度组织学病变 ,提示可判为阳性 ;OP阴性对照组 5例 ,只有 3例 (6 0 % )组织学完全正常 ,余 2例 (4 0 % )虽然组织学也绝大部分正常 ,但有局部 OP样病变。病理切片对比表明 ,X线 OP阳性 (含可疑 ) 10 0 %获病理组织学证实 ;For evaluating the value of X-ray diagnosis in avian osteopetrosis(OP),50 representative cases including 15 X-ray weakly positive(+) cases,5 X-ray moderately positive(++) cases,15 X-ray strongly positive(+++) cases,10 X-ray suspicious cases(±) and 5 X-ray negative(-) cases,and 1 batch of chickens with rickets complicated with OP,were selected from the farm and experimental chickens for histopatologic examination after performing X-ray graphy of their tibia.The results showed that all three X-ray osteopetrosis positive groups had structural changes to some degree.Ten X-ray suspicious(±) osteopetrosis cases showed slight change in structure too.Thus they could be considered OP positive.Three cases of 5 X-ray negative chickens(60%) had no pathologic changes,while,enlargement of the spaces were observed in another 2 cases(40%).Comparing to the histopathologic findings,X-ray diagnosis were 100% confirmed by histopathology.However,in arriving at a X-ray negative diagnosis,we should be careful.
