[The comparative characteristics of the biological and immunomodulating activities of enzyme preparations of microbial origin].

A number of enzyme preparations of microbial origin such as immunomodulators and immunostimulators have been studied in vitro according to reactions of rosette technique of cell (ROC) active and general, adhesion, activation of a complement and also the spontaneous activity and phagocytosis of neutrophils have been determined. The enzyme preparations of microbial origin have been shown to be capable of causing immunomodulation and of influencing the specific and nonspecific immune response. Unlike the enzymes of animal origin the enzymes of microbial origin are effective in smaller concentrations.

[Endoscopic removal of small intestinal polyps in total polyposis of the digestive tract].

In patients with proliferative and mixed forms of total polyposis of the digestive tract the intestinal polyps are mainly localized in the duodenum, with hamartomal polyposis--in the jejunum and ileus. The endoscopic polypectomy from the small intestine may be performed intraoperatively and during endoscopy under narcosis. 174 polyps with the diameter of 0.
