| Abstract: | The results of investigations are presented concerning the disorders of metabolism of mitochondria isolated from the liver of rats after various operations on the portal vein and hepatic artery. The mitochondria were studied after end-to-side portocaval anastomosis (PCA), end-to-side anastomosis of the mesenteric vein to the inferior caval vein (M-PCA) and after hepatic artery ligation. The investigations were carried out 3.5 months after these operations. The obtained results showed that the greatest and most significant statistically dissociation of oxidative phosphorylation and reduction of oxygen uptake developed in the mitochondria isolated from rats after M-PCA anastomosis. Simultaneously conducted investigations of citrulline production by suspension of mitochondria failed to demonstrate any changes in the urea cycle. |
