Osteopetrosis appears spontaneously on the "op" rat (Fatty/ORL). At the confirmed stage, description of histologic lesions is made. The attention is attracted by an endocavitary tissue observed at later stage of disease. This one does not seem to be the result of a metaplasia but rather the image of a persistent osteoblastic activity.
骨硬化症在“op”大鼠（Fatty/ORL）中自发出现。在确诊阶段，对组织学病变进行描述。疾病后期观察到的腔内组织引起了关注。这似乎不是化生的结果，而是持续成骨细胞活性的表现。
