Resumo: |
Two studies were conducted to verify the ability and the effects of intoxication beans Stryphnodendron fissuratum in pregnant cows with different concentrations. In the first experiment, the abortive properties and the clinical features of poisoning by the pods of S. fissuratum were studied in 8 pregnant cattle. One cattle that ingested 3 daily doses of 3.0 g/kg body weight and 1 that ingested 3 daily doses of 3.3 g/kg of the pods showed digestive clinical signs and aborted, but a higher dose was fatal. Signs of the digestive and central nervous system were observed in cattle that received the pods of the plant. One cattle and other two that ingested doses of 6.5 g/kg and 7.5 g/kg, respectively, did not showed clinical signs and delivered normal calves. These results demonstrate that S. fisuratum causes digestive and nervous disorders, beyond abortion in cattle. In the second experiment aimed to characterize the macroscopic and histopathological lesions of poisoning by S. fissuratum (Mimosoideae). Its pods were given orally to 8 cattle. The cattle that received doses of 9.0 g/kg and 10 g/kg died poisoned. One cattle that received dose of 6.5 g/kg recovered. Only the animals that received one dose of 7.5 g/kg did not become sick. At post-mortem examination the main lesions were digestive associated and consisted in breaking up of the epithelium and congestion of the mucosa of forestomachs and abomasum. Widespread areas of erosion and ulceration were observed at oral mucosa, esophagus, reticulums and abomasums mucosa. At these areas the main lesions were neutrophils infiltration, vacuolization of the epithelial lining, swelling and dissociation of cells with cytoplasmic eosinophilia, pyknosis, karyorrhexis and nuclear karyolysis. At the central nervous system, the main lesions were identified in the brain of goats that received 10 g/kg of pods and consisted of spongiosis of the brainstem’s white matter. The poisoning was characterized by damage to organs of digestive system, kidney and central nervous system. |
