Evidence from divergent sources suggests that some forms of interstitial pulmonary disease are associated with abnormalities of the cellular immune system. To evaluate whether cellular immune processes are necessary determinants for the development of parenchymal alveolitis and fibrosis secondary to bleomycin, we examined the effect of bleomycin on the NIH,(More)
This study suggests one mechanism by which alveolar macrophages accumulate in the lung in pulmonary emphysema: elastin fragments generated at the diseased sites are potent chemoattractants for monocytes, the precursors of the macrophages. The most chemotactic elastin fragments have a molecular weight between 10,000 and 50,000 and are active at(More)
The tight-skin (Tsk/+) mouse is a genetically determined model characterized by alveolar enlargement and physiologic evidence of emphysema. Morphologic evaluation of the lungs of these animals demonstrated increased numbers of potential protease-secreting cells (alveolar macrophages and neutrophils) in the lower respiratory tract prior to development of the(More)
The tight-skin (Tsk/+) mouse represents an autosomal dominant mutation characterized by increased thoracic size, large lungs, and a variety of abnormalities of loose subcutaneous connective tissue, cartilage, tendon, and bone. Because an increase in the size of the lung and thorax may result from destruction of alveolar walls and a loss of elastic recoil of(More)
The superior colliculus (SC) plays a central role in the control of saccadic eye movements and has also been implicated in control of covert spatial attention. While there is a growing body of evidence from studies of awake behaving primates that supports these proposals, direct evidence from humans has been sparse. In the present study we tested a patient(More)
To evaluate the concept that genetic factors modulate susceptibility to agents that cause interstitial lung disease, animal models of interstitial lung disease caused by bleomycin or by inhalation of organic particulates (ovalbumin or bovine gamma globulin after specific immunization) were studied in strains of mice with different genetic backgrounds.(More)
R apid advances and developments in optical imaging technology during the past 15 years have resulted in promising innovations in the realm of high-resolution imaging of the functional architecture of the brain, which has not only contributed to the elucidation of brain functional architecture and plasticity (see reviews) but has also increased our(More)
