Effect of branched chain amino acids on liver regeneration after partial hepatectomy.
The authors investigated the effect of the enrichment of commercial amino acid solutions with branched chain amino acids on the development of liver regeneration. Partial (65-70%) hepatectomy was performed on male Wistar rats (140-160 g body weight). Starting with the day of the operation, amino acid solutions normally used in clinical practice and the same solutions enriched with branched chain amino acids were administered by stomach tube; 24, 48 and 96 h after the operation the animals were decapitated. The onset of DNA synthesis was found to be more rapid in animals given the enriched solutions. Once regeneration had started, the stimulant effect of an increased supply of branched chain amino acid on liver regeneration was smaller. Nevertheless, even in the later phase after partial hepatectomy branched chain amino acids had a stronger stimulant effect on liver regeneration after partial hepatectomy than an energy supply in the form of sorbitol.
