[Morphometric investigations on lungs of children in perinatal period (author's transl)].

Morphometric indices were investigated by the method of Dunnill (1974a) on 4 lungs of intranatal stillborns and 4 lungs of preterm liveborns with hyaline membrane disease (HMD). The values of the air-tissue interface ranges for stillborns between 0,16 and 0,37 m2. The values for lungs with HMD lies between 0,09 and 0,17 m2 and therefore distinctly lower. Number of alveoli in the entire lung ranges for stillborns between 8.3 and 13.9 x 10(6). The values for lungs with HMD ranges between 0.6 and 3.9 x 10(6) and therefore distinctly lower, too.
