We have examined the lungs of eleven species of newborn mammals by quantitative
morphometric techniques and related the findings to body weight (BW) and O 2 …

As the lung grows in volume from infancy to adult life, considerable amounts of tissue are
added to the lung, mostly as a result of alveolar multiplication. Species differences may exist …

Elastin has long been thought to play a pivotal role in alveolar septal development by
providing the structural framework around which new alveoli develop in the immature lung …

Morphometric examination using light, scanning electron, and transmission electron
microscopy was performed on the lungs from 32 inbred male BALB/cNNia mice between 38 …

Stereological estimations of total capillary length have been used to characterize changes in
the alveolar capillary network (ACN) during developmental processes or pathophysiological …

We administered a glucocorticosteroid (dexamethasone) or its diluent to pregnant rats on
gestation days 17, 18, and 19. In male offspring we determined the lung's gas exchange …

Applying the zone concept described previously, we quantitatively analyzed fetal rat lung
development. The zone concept allowed us to coherently define reference spaces in the …

An overview of the epithelial and interstitial composition of rat respiratory airways shows
complexity and variability. Airway epithelium varies in 1) different airway levels; 2) the types …

Chronic obstructive pulmonary disease (COPD) is one of the most common lung diseases.
The major component of COPD, which affects the gas-exchanging parenchyma of the lung …

Little is known about lung function during early stages of postnatal maturation, although the
complex structural changes associated with developing rat lung are well studied. We …
