[Liver regenerative potential of the lake frog Rana ridibunda after partial hepatectomy].

A histomorphological study of the regenerating liver of Rana ridibunda, within 2 months after partial hepatectomy, shows that regenerative processes on the wound surface are slowly proceeding. Processes of reticular fiber reconstruction occurred in the composition of the basal membrane of liver sinusoids. A cytophotometric study shows that glandular cells in R.

[Effect of simultaneous partial pancreatectomy on liver regeneration in domestic chickens].

Simultaneous partial pancreatectomy does not change the fundamental mechanisms of reparative regeneration of the chick liver, taking the course of regeneration hypertrophy. Nevertheless it introduces some temporary and quantitative alterations into this process. Later on the connective tissue is formed on the wound surface and infiltration of the resected organ lobe with eosinophilic leukocytes takes place.

[Nonspecific esterase and alpha-glycerolphosphate dehydrogenase activity and the fat content in the regenerating chicken liver].

The data on histochemical study of changes in the activity of esterases, alpha-glycerophosphate dehydrogenase and the fat content in the chick regenerating liver are presented. The accumulation of the fat in hepatocytes during the early periods of regeneration (1--5th day of the experiment) is partially conditioned by the reduction of the activity of nonspecific esterases. The maximal liver steatosis is accompanied also by an increase in the activity of alpha-glycerophosphate dehydrogenase which indicates intensification of glycolysis and synthesis of triacylglycerines (liver spare lipids) during regeneration.
