title: [Clinical and morphological changes in the hoof sole of large ruminants with inflammatory diseases].
abstract: Clinical, morphological, and histomorphological investigations were carried out of the changes taking place in the solar matrix in some more common diseases in cows raised in the conditions on the enlarged farms of industrial cattle breeding. With the traumatic aseptic inflammations of the solar matrix the nova and its effect predetermine histologically the various degrees of changes, consisting in circulation disturbances, oedema of the connective tissue, disintegration of the connective tissue bundles, divergence of the collagen fibres, mucinous dystrophy, fibrinoid-necrotic foci, and heterophilic infiltration around the blood vessels and in their wall (arteriitis and periarteriitis). In suppurative inflammations of the solar matrix the process assumes diffuse character with strongly manifested leukocytic infiltration, with the development of dystrophic necrobiotic processes. As a result of these partially or more widely expressed separation (exungulatio) of the solar horn tissue from the matrix sets in. In the initial stage of the traumatic sole ulcer are observed the signs described for an aseptic inflammation. Later on the processes assume a more strongly manifested course, involving the matrix with atrophy and necrosis, separation of the hoof horn from the matrix. With the secondary complication with pathogenic organisms the signs of purulent and necrotic inflammation are seen, resulting in an ulcus defect.
