Abstract
The study evaluated the effect of portacaval anastomosis on the regeneration ability of the liver after partial hepatectomy in rat. The regeneration of liver was evaluated using the following tests: deoxyribonucleic acid synthesis, the activity of tyrosine aminotransferase (TAT) and the concentration of DNA and RNA in subcellular fractions of liver obtained by differential centrifugation. The results indicate the harmful effect of the portacaval shunting on the liver proliferation, which was near 50% decreased and the peak of the regeneration was delayed for about 12 hours. The most significant changes were observed in the nuclear and cytoplasmic fraction. In addition, high mortality ratio was found in the animals with portacaval anastomosis followed by partial hepatectomy.
