The gastrointestinal diseases of horses are aggravated by complications such as laminitis. The laminitis etiopathogeny are connected with lamellar basement membrane degradation by matrix metalloproteinases (MMPs). Inflammatory cytokines and leukocytes enzymes can active MMPs. The object of this study was to evaluate morphological changes on lamellar tissue of horses with colic syndrome and its association with clinical and laboratorial parameters. It was observed intensive destruction of lamellar architecture, mainly on animals with severe physical and laboratorial alterations, such as delayed capillary refill time, congested mucous membrane, tachycardia, hemoconcentration and low count of platelet and leukocytes. The results sign to the most likely moment of development of lamellar tissue injuries in horses with colic syndrome, which can be adopted preventive measures against laminitis. |
