[Urea as an antimicrobial and dehydration agent for the local treatment of suppurative surgical infection].

The 30% solution of urea is found to be an effective quick-acting means against gram-positive and gram-negative pyogenic microflora. Microorganisms discharged from purulent foci of patients were sensitive to the drug in 100% of cases. The local application of the 30% urea solution as irrigation used in 156 patients with pyo-surgical infection has shown the drug to be well endured by the patients.

[Method of isolating alveolar macrophages and their functional capacity].

A number of modifications are suggested concerning the method for isolation of alveolar macrophages and the technique for their further handling. To study phagocyte function of alveolar macrophages in suspension, the modification of the method is described, which had been offered by the authors before for the determination of the index of complete phagocytosis by peripheral blood leukocytes.
