RESUMO
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.

Thanatogenesis of pulmonary tuberculosis has been studied on autopsy material gained in tuberculosis hospitals of Moscow from 1972 to 1992. The leading cause of lethal outcomes was progressive fibrous-cavernous tuberculosis (71.6% in 1992). Disseminated tuberculosis mortality rose two-fold (14.2% in 1992). Death rate for infiltrative tuberculosis reaches now 5.56%. Tuberculous patients die of the progressive disease in 54.94%, of respiratory distress and cardiac insufficiency in 32.72%. Progressive tuberculosis proved to combine with nontuberculous diseases in 71.87% of the cases.
