Single Time Heated Different Vegetable Oils Use-Impact on the Magnitude of Total Parenteral Nutrition (TPN) Associated Adverse Effects

Healthy adult rabbits of local strain were divided into 5 groups (n= 8). The study was divided into 2 phases. Phase I: oil feeding; the first set of rabbits served as control and fed on a normal rabbit diet. Four sets of rabbits were treated for 16 weeks with 1 ml/kg/day of single time heated olive (STH-OO), canola (STH-CO), sunflower oils (STH-SO) or a mixture of these oils (STH-MVO). In phase II: TPN was given to each group, including the control group, for 2 weeks. Before and after TPN therapy, body and liver weights were measured. Plasma lipid profile [triglycerides, total cholesterol, high-density lipoproteins, low-density lipoproteins, very-low-density lipoproteins], liver function marker [total-protein, albumin, total and direct bilirubin, serum glutamic pyruvic transaminase, serum glutamic-oxaloacetic transaminase, gamma-glutamyl transferase, and alkaline phosphatase], oxidative stress and tissue damage parameters [malondialdehyde, C-reactive protein, lactate dehydrogenase, and creatine phosphokinase] of all the groups weremeasured at the end of TPN therapy.
