Abstract

The present study was conducted to obtain information on the effects of various dietary doses of the Acrylamide on Wistar rats. Emphasis was put on changes on growth and serobiochemical constituents of treated rats. Extra pure Acrylamide was fed to Wistar rats at 10, 30, 60 and 90 mg/kg, respectively of the standard diet for 6 weeks. Acrylamide was then withdrawn from the diet for four weeks. Incorporation in diet of the doses 10, 30, 60 and 90 mg/kg acrylamide was toxic to Wistar rats, but fatal only to those of group 5 fed on 90 mg/kg, where five rats (62.5%) died on day 18 of the experimental period. Depression in growth was observed in rats that had been fed on the experimental doses for 6 weeks. Neurotoxicity was observed only in the rats fed on acrylamide at 10 (Group 2) and 60 mg/kg (Group 4). These findings were accompanied by alterations in serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) activities and albumin, globulin and cholesterol concentrations. The alteration on enzymes activities, urea and cholesterol remained even after the 4 weeks withdrawal of acrylamide, whereas, total protein, albumin, globulins and electrolytes concentration returned to their normal values. Acrylamide is considered neurotoxic at dietary levels of 10 and 60 mg/kg and enterohepatonephrotoxic to Wistar rats at dietary level of 10, 30, 60 and 90 mg/kg and fatal at the treatment dose of 90 mg/kg.
