[The amino acid background of patients with obstructive jaundice before and after the surgical removal of the obstacle to bile outflow].

The amino acid pool of blood plasma, liver and bile was examined before and after operative elimination of biliary hypertension cause. The blood plasma concentration of the majority of free amino acids (especially the sulfur-containing and big neutral) before operation at cholestasis is increased in comparison with donors. For the bile outflow normalization after operation the most informative is the content in liver, blood plasma and bile of taurine, glycine and the amino acids metabolically associated with them.

[Informative value of amino acid reserve in the blood plasma in cholestatic and septic syndrome].

Syndrome of cholestasis is characterized by pronounced increase in concentration of the sulphur containing, ketogenic amino acids and intermediates of a cycle of urea formation in the blood plasma; sepsis--by decrease in pool of glycogenic amino acids, increase in concentration of free ammonium and reduction in correlation of amino acid concentration with branched hydrocarbon chain of aromatic amino acids. In cholestasis, the levels of ammonium alpha-amino butyrate and aromatic amino acids were the most informative indices, in sepsis--content of lysin, glutamate, cystein and cysteate.

[Diagnostic and therapeutic laparoscopy in surgical practice].

The results of laparoscopy in 1,000 patients with various diseases are analysed. The indications for laparoscopy in different groups of patients are shown. Various laparoscopic operations were carried out on 789 patients.
