We have previously demonstrated that fetal ethanol exposure deranges the function and viability of the neonatal alveolar macrophage. Although altered differentiation of the alveolar macrophage contributes to pulmonary disease states within the adult lung, the effects of fetal ethanol exposure on the normal differentiation of interstitial to alveolar macrophage in the newborn lung are unknown. I...

Although studies of the composition of alveolar air have been invaluable to the advance of respiratory physiology a precise definition of alveolar gas pressures and the accurate sampling of alveolar air have proved elusive goals (1). Owing to the cyclic nature of the ventilatory process the partial pressures of 02 and CO2 in the alveoli are changing continually (time factor) (9), and, owing to ...

 Abstract Alvelolar hydatid disease is caused by E. multilocularis. Human infection occurs at the larval stage of this small tape worm (1.2 to 4.5 mm). In this article we studied alveolar hydatid disease in a 50 year old woman who presented with a hepatic mass. Liver biopsy and histopathologic evaluation showed alvelolar hydatidosis of the liver. Then resection of the left lobe of liver was don...

I N THE past many different methods have been employed for the direct sampling of alveolar air. A sound criticism of the validity of the technique has usually been futile since one was at loss to define or determine mean alveolar composition. The ease with which alveolar air composition can be altered by the slightest change in ventilation is very impressive and makes one aware of the possibili...
