Effect of realimentation after several days' pure carbohydrate intake on DNA synthesis in regenerating rat liver.
The authors studied the effect of realimentation after several days' isolated glucose or fructose intake on DNA synthesis in liver regenerating after partial hepatectomy (PH) (65-70%) or after carbon tetrachloride (CCl4) poisoning 1.5 ml/kg. Two days before PH or the administration of CCl4 and two days after, the experimental rats were given glucose (50% solution) of fructose (50% solution) as the only source of energy. Rats with PH were then fed for one day on a standard laboratory diet (25 cal% protein) or a high protein diet (81 cal% protein). Rats with CCl4 liver damage were fed for one day on the standard laboratory diet only. In the rats given glucose, liver DNA synthesis and the total amount of these nucleic acids in the liver 48 hours after CCl4 administration was lower than in the controls or the rats given fructose. In all the experimental groups (PH and CCl4), stimulation of liver DNA synthesis was observed after one day's realimentation. The total DNA content of the liver of rats with PH rose markedly during realimentation. The experiments indicate that the regenerative activity of damaged liver can be influenced by the nutritional regimen.[1]References
