introduction: the respiratory system is both a route of entry and exit for toxins and injurious agents, as well as being a target for chemical substances and pathogens. therefore, an understanding of the structure and function of the migratory cell populations of pulmonary tissues including alveolar macrophages is central in a number of important disease processes. this study aimed to identify ...

In this study the nature of chromosomal proteins, his tones and nonhistone in resident alveolar macrophages was investigated in comparison to peritoneal neutrophils and calf thymus proteins. Cells were obtained by lavaging the lung and after purity determination they were subjected to fractional extraction procedures. Proteins were then analysed on SDS polyacrylamide gels and densitometric...

The role of alveolar macrophages in the production of granulocyte/ macrophage colony-stimulating factor(s) by the rat lung was investigated. Lavaged lungs, when incubated at proper weight per volume of culture medium, produced the same amount of colony-stimulating factor as unlavaged ones. Both lavaged and unlavaged lungs produced similar types of colony-stimulating factor (s). Prolonged i...

background: it has been shown that inhalation of carbonaceous particulate matter may impair lung function in children. objective: using the carbon content of airway macrophages as a marker of individual exposure to particulate matter derived from fossil fuel, we sought direct evidence for this association. methods: 300 children from puffed rice industrial areas and 300 children from population ...

in this study the nature of chromosomal proteins, his tones and nonhistone in resident alveolar macrophages was investigated in comparison to peritoneal neutrophils and calf thymus proteins. cells were obtained by lavaging the lung and after purity determination they were subjected to fractional extraction procedures. proteins were then analysed on sds polyacrylamide gels and densitometric scan...

introduction: it has been shown that gama-ifn is one of the major cytokines involved in lung fibrosis. it has also been demonstrated that nitric oxide (no) may exert vasodilation, edema and cytotoxicity, and it may stimulate cytokinedependent processes in the lungs. in this study, the effect of 17-beta estradiol (17-betae2) and five alpha dihydrotestosterone (5alfa-dht) on no release by tgf bet...

Two groups of antibodies against mouse resident alveolar and peritoneal macrophages have been raised individually in rabbits by immunization with whole cell suspensions of lavaged alveolar and peritoneal macrophages. The whole antisera reacted positively with neutrophils and lymphocytes. However, upon extensive absorptions with these cells the activity became restricted to macrophages. The...
