Forty-eight digits of 8 dairy cows, which had been diagnosed as sole ulcers in one or two hooves, were examined histopathologically and classified into 5 grades on the basis of the severity of the circulatory disturbances and of keratogenesis. All the cows had significantly higher grades than normal cows. Although hind lateral digits were most severely damaged, there were no significant differences in the grades among claw positions except hind lateral digits. From these results, it is suggested that the cows affected with sole ulcers had some systemic factors predisposing all the digits to digital disorders.
对8头奶牛的48个蹄趾进行了组织病理学检查，这些奶牛被诊断为一两个蹄部患有蹄底溃疡，并根据循环障碍和角质形成的严重程度分为5个等级。所有患病奶牛的等级均显著高于正常奶牛。尽管后外侧蹄趾受损最为严重，但除后外侧蹄趾外，不同蹄爪位置的等级之间没有显著差异。从这些结果可以推测，患有蹄底溃疡的奶牛存在一些全身性因素，使所有蹄趾都易患蹄部疾病。
