Macro- and microscopical changes in the hooves of 14 cattle having a clinically established diagnosis of laminitis are described, Deviation of the pedal bone was found in 10 of the animals. In acute laminitis, the microscopical changes in the corium were hyperaemia, oedema, thrombosis and haemorrhages. Degenerative changes were found in the epidermis especially in the vicinity of thromboses of vessels in the corium. In chronic laminitis, arteriolosclerosis and arteriosclerosis were constant findings in the corium. There was also a high frequency of chronic thrombi and chronic granulation tissue. Prominent features in the lamellae epidermales were hyper- and parakeratosis. As judged from changes in arterioles and arteries, hypertension is suggested to be a pathogenetic factor in bovine laminitis. cattle; laminitis; histology; arteriolosclerosis; arteriosclerosis.
描述了14头临床确诊为蹄叶炎的牛蹄的宏观和微观变化。在10头动物中发现蹄骨偏移。在急性蹄叶炎中，真皮的微观变化为充血、水肿、血栓形成和出血。在表皮中发现退行性变化，尤其是在真皮血管血栓形成附近。在慢性蹄叶炎中，真皮中常出现小动脉硬化和动脉硬化。慢性血栓和慢性肉芽组织的发生率也很高。表皮板的突出特征是角化过度和角化不全。从细动脉和动脉的变化判断，高血压被认为是牛蹄叶炎的一个致病因素。牛；蹄叶炎；组织学；小动脉硬化；动脉硬化。
