[External secretion of the liver in enteral and intragastric tube feeding].

Hepatic external secretion and main lipid components of the bile and serum were studied under a long-term intragastric and enteral tube feeding using improved surgical and technical methods, Inritan and Peptisorb mixtures. It is shown that food entering the stomach directly does not affect hepatic excretion, while enteral 2-week feeding, especially with hydrolyzed products, deranged secretory mechanisms which entails unbalance in the main bile components and defective lipid metabolism.

[Study of the nucleoprotein composition of sheep liver subcellular fractions in relation to heterosis].

A comparative characteristic of the liver main cellular organoids is given for sheep of different age and origin. Crossing of different types of sheep breeds (Krazakh fine-wool and Lincoln) results in an increase in the amount of nucleic acids and proteins in nuclei and microsomes and does not influence other cellular structures of cross-breeds.
