Diacetoxyscirpenol was found to have a large V(,d) and total body clearance which suggested that it was widely distributed to and metabolized in the peripheral as well as the central compartment. Less than 1 percent of the dose of DAS was recovered in the urine of both species. High concentration of monoacetoxyscirpenol and scirpentriol were found in the plasma and urine suggesting that hepatic deacetylation of DAS is an important route of DAS biotransformation. Residues of DAS were found in skeletal muscle, liver, kidney, and lymphoid tissues at 8 hours following dosing. The T(, 1/2) of DON in plasma ranged from 2.0 to 3.7 hours and the 24-hour urinary excretion of DON ranged from 28.1 to 57.2 percent of the dose. Deoxynivalenol was both secreted and reabsorbed by the renal tubules. Residues of DON were not found in skeletal muscle 24 hours following dosing.","Diacetoxyscirpenol was destructive of proliferative and metabolically active tissues. Enterocytes in different anatomical regions of the bowel had differing susceptibilities to DAS. Diacetoxyscirpenol was preferentially more cytotoxic to B-lymphocytes as compred to T-lymphocytes. Diacetoxyscirpenol was cytotoxic to specialized ion pumps; namely, renal tubular, gastric parietal, and salivary ductular cells. Endothelial necrosis and hemorrhage were observed in the brain. Pancreatic acinar and islet cellular necrosis were observed in the DAS and DON-treated pigs.","Following exposure to DAS, hematologic changes were observed in swine, dogs, and cattle. These changes included marked disruption of granulocyte and lymphocyte kinetics. Bone marrow damage was observed in the DAS treated animals.","Changes in blood glucose were observed in all of the pigs dosed with DAS and DON, suggesting that under field conditions changes in intermediary metabolism appear to be an important aspect of the toxicity of the 12,13-epoxytrichothecenes.","Made available in DSpace on 2014-12-16T06:35:36Z (GMT).
