Abstract
Experimental diabetes was induced in 4 wethers of the Mutton Merino breed by intravenous injection of alloxan (75 mg.kg-1) in order to determine its impact on plasma glucose, immunoreactive insulin, free fatty acids (FFA), cholesterol, phospholipids, triglycerides, D-(-)-3-hydroxybutyrate (D-3-HB), bilirubin and aspartate aminotransferase (ASAT) as well as on the changes of these parameters brought about by an intravenous infusion of sodium n-butyrate (1 mmol.kg-1). Alloxan administration caused a significant elevation of plasma glucose, FFA, triglycerides, cholesterol, phospholipids, D-3-HB and bilirubin and a decrease of the level of immunoreactive insulin. The increase in glucose level brought about by a bolus injection of sodium n-butyrate in untreated sheep did not appear in alloxanized animals. Thus, it is suggested that the lack of hyperglycaemic response in diabetic sheep was due to the absence of liver glycogen stores. Unexpectedly in alloxan-diabetic sheep, a decrease in the plasma level of FFA occurred after the administration of sodium n-butyrate. Therefore, it may be assumed that beside insulin other factors may contribute to the decrease of FFA under these conditions.
