[Modeling of pulmonary cysts and a method of their treatment]

A cyst of the lung was modelled by implanting a celloidin ball into its tissue. Experiments were conducted on 43 male and female mongrel dogs whose weight ranged from 8 to 22 kg. Implantation of a foreign body into the lung leads to the development of an inflammatory reaction in its tissue with the formation of a connective-tissue capsule which can be compared with acquired cysts of the lung. Liquidation of an experimental cyst by means of MK-7 glue causes aseptic inflammation terminating in the formation of a connective-tissue scar.
