[Submicroscopic and immunochemical study of horseradish peroxidase passage through the epithelium of the bronchial mucosa].

2% solution of horseradish peroxidase (HRP) was placed on the bronchial mucosa of anaesthetized dogs through a bronchoscope. Arterium femoralis and thracal lymphatic duct were canulated to HRP application. The radiate immunoprecipitation method was utilized to assess HRP activity in blood and lymph samples.

[Participation of the lungs in carbohydrate and lipid metabolism].

The utilization of glucose, NFA, triglycerides, cholesterol and alpha-lipoprotein cholesterol as well as the production of lactic acid were studied at different pH levels on the model of isolated lungs of the dog perfused in a special chamber maintaining the conditions close to physiological. The data obtained may be used for the assessment of lung metabolism under these conditions.
