[Method of stretching of the lung tissue for morphometric studies].

Preparation of lung tissues for morphometric studies requires their preliminary morphometric studies requires their preliminary reexpansion which is usually being done by blowing of the whole intact lung followed by fixation. A method is proposed for reexpansion of the lung tissue pieces. Experiments in normal guinea pigs showed the lung tissue reexpanded by this method to increase in volume 1.82 +/- 0.023-fold as compared with the lung volume in the animal thorax at completely relaxed respiratory muscles.
