New morphometric procedures allow selection of alveoli for analysis in an unbiased manner and then to determine the volume of individual alveoli. The latter, together with the easily measured lung volume, allows the calculation of alveolar number. Th

We studied the effect of 13% O2 on the development of the lung's gas-exchange region. Rats, acclimatized to 13% O2, remained in 13% O2 while pregnant, and were kept with their pups in 13% O2 until the pups were killed or were placed in air at age 15

Pulmonary alveoli, the lung's gas-exchange structures, are formed in part by subdivision (septation) of the saccules that constitute the gas-exchange region of the immature lung. Although little is known about the regulation of septation, relatively

Nonpregnant female rats were kept in 13% O2 for greater than 3 wk before being bred, throughout pregna ncy, and, with their pups, after birth; control rats were only in air. The average volume (v), number (N) and surface area (Sa) of gas-exchange str

We examined the effect of the ventilatory rate and the temperature of excised lungs and of increased body temperature of anesthetized spontaneously breathing rats on the centrifugal sedimentation of disaturated phosphatidylcholine (DSPC) present in l

We placed pregnant rats in 10% O2 on the last day of gestation for less than or equal to 9 h plus 1-2 h (with their pups) after the onset of delivery. In the pups this brief perinatal hypoxia led to an altered cellular composition of the bronchiolar

We used ultrastructural morphometric methods to study the in vivo regulation of secretion in bronchiolar Clara cells of rats. The Clara cells studied were located in airways with an internal diameter of 0.21 +/- 0.06 mm (mean +/- SD) at a transpulmon

The gas exchange region of newborn rats is composed of large thick-walled gas exchange saccules that become subdivided by septum formation between ages 4 and 14 days. Dexamethasone given daily from age 4 to 13 days irreversibly prevents septation. We

We studied the effect of breathing 10% O2 for less than or equal to 9 h by rat dams during the last day of gestation and (with their pups) for 1-2 h immediately after birth on the development of the lung's gas exchange region in the pups. Our major f
