The aim of this study was to describe gastric, hepatic, and renal lesions inThoroughbred Racing horses associated to the equine gastric ulcer syndrome. Thirtyhorses with a history of gastric ulcer syndrome and recurrent colic during 2006 to 2007 atthe Race Track «La Rinconada», Caracas, Venezuela were evaluated. Horses were euthanized and the necropsy was conducted. Tissue samples were collected from stomach,liver and kidney, and processed by conventional histological methods. In the stomach,the mucosa was intact but areas of hyperaemia and hyperkeratosis were observed in 6cases, multifocal small erosions or ulcers in 6 cases, multifocal large ulcers with areas ofextensive erosion in 12 cases and extensive areas of ulceration with exposure of thesubmucosa in 6 cases. The macroscopic evaluation of the liver showed evidenthepatomegaly in 22 cases and lobular pattern in 18 cases. The kidn...

A clinical and pathological study was conducted on musculoskeletal catastrophic lesions of the locomotive apparatus occurred in 78 Thoroughbred horses in the racetrack «La Rinconada», Caracas, Venezuela, during 2000 to 2007. Blood samples were collected for hematological, biochemical and parathormone analysis in blood. Also, urine samples for phosphate levels. All animals were euthanized due to severe lesions, and bone, tendons, stomach, kidney and liver samples were taken for by histopathology evaluation. Clinical exams revealed lameness grade IV-V in all animals. Losses of bone continuity (fracture) occurred in all cases, and exposition of bone structures, joint damage, rupture of tendons and ligaments and vascular destruction were observed in 60% of them. The types of fractures were comminuted (60%), oblique (25%) and spiral (15%). Blood and urine values were affected. Necropsy show...

Se hizo un estudio clínico-patológico de las lesiones músculo-esqueléticas catastróficas ocurridas en pruebas públicas en el Hipódromo “La Rinconada”, Caracas, Venezuela, entre el 2000 al 2007. Se trabajó con 78 equinos Pura Sangre de Carrera con lesiones del aparato locomotor. Se colectó muestras de sangre para estudio hematológico, bioquímico y hormonal (paratohormona), así como muestras de orina para determinar niveles de fosfatos. Se les practicó la eutanasia debido a la severidad de las lesiones y se realizó la necropsia. Se tomó secciones de tejido óseo para determinación de calcio y fósforo, y de tejido muscular, tendinoso, gástrico, renal y hepático para estudio histológico. Los exámenes clínicos revelaron claudicación grado IV-V en todos los animales. La pérdida de continuidad ósea (fracturas) ocurrió en todos los casos, y exposición de estructura...
