Abstract:
Objective To study the effect of total nutrient admixture (TNA) on lipid metabolism in rats with acute hepatic failure (AHF). Methods Fifty-six male Wistar rats were randomly divided into four groups: normal diet group, nitrogen-free diet group, fat-free nutrient admixture group, and TNA group. All rats were injected with D-galac- tosamine to induce AHF model Meanwhile, 6 healthy Wistar rats were used as control group. TNA provided energy 221.75 kJ (1 kcal=4.184 kJ), nitrogen 0.365 g, nitrogen to energy ratio 1:145, amino acids 2.28 g (including branched-chain amino acid 0.70 g), glucose 7.85 g, and fat 1.25 g on a daily basis. After 10 days of the operation of Jugular vein puncture tube, blood glucose, blood lipid, liver and renal function were determined. Results The blood glucose level was significantly higher in TNA group than that in fat-free nutrient admixture group (P < 0.05). The levels of serum triglyceride and cholesterol were highest in fat-free nutrition admixture group, and triglyceride level was signif- icantly higher than that in normal diet group and nitrogen-free diet group (P <0.05). The levels of serum triglyceride and cholesterol were significantly higher in TNA group than those in normal diet group (P <0.05). The levels of ala- nine aminotransferase, alkaline phosphatase, total bilirubin and blood urea nitrogen were lower in TNA group than those in fat-free nutrient admixture group (P < 0.05). Conclusion The nutritional proportion of TNA is suitable for the metabolism disorder of hepatic failure, and therefore TNA can reasonably promote the anabolism and reverse the deteri- oration of hepatic failure in rats.
