چکیده

BCG treatment of rabbits, guinea pigs and rats yielded alveolar exudate cells (AEC) which had higher viability and increased potential of adherence to glass coverslips. Moreover, these AECs consisted of higher number of macrophages when obtained from animals treated with BCG. Recovery of macrophages from AECs was higher in rabbits than guinea pigs and rats. Different laboratory animals exhibited pronounced phagocytic and bactericidal activity when stimulated with BCG and compared with their respective controls. Opsonization resulted in enhanced macrophage activity.

Effect of ammonia on in vivo and in vitro immune responses.

The effects of exposure of animals to ammonia on their delayed type of dermal response, the mitogenic and antigenic responses of their lymphocytes, and the bactericidal and phagocytic activities of their alveolar macrophages were examined. Experimental guinea pigs vaccinated with Mycobacterium bovis BCG were exposed to 3.75 micrograms of ammonia per dl of air (50 ppm) or 6.75 micrograms of ammo...

Mycobacterium bovis BCG vaccination augments interleukin-8 mRNA expression and protein production in guinea pig alveolar macrophages infected with Mycobacterium tuberculosis.

Alveolar macrophages are likely the first cell type to encounter Mycobacterium tuberculosis in a pulmonary infection, resulting in the production of chemokines. In order to evaluate this response, alveolar macrophages harvested from nonvaccinated and Mycobacterium bovis BCG-vaccinated guinea pigs were infected in vitro with live M. tuberculosis H37Ra or H37Rv (multiplicity of infection, 1:1) or...

Studies on the Mechanism of Immunity in Tuberculosis

1. Tuberculous and vaccinated rabbits and guinea pigs mobilize mononuclear phagocytes at the site of a non-specific inflammation with greater rapidity than do normal animals, just as they respond to tubercle bacilli. 2. The succession of cells that characterizes inflammation in general is accelerated in allergic rabbits and guinea pigs in response to non specific irritants. 3. The pH at the sit...

Effects of oxygen exposure on it vitro function of pulmonary alveolar macrophages.

Bacterial infection may complicate pulmonary oxygen (O2) toxicity, and animals exposed to high O2 concentrations show depressed in vivo pulmonary bacterial inactivation. Therefore, in vitro studies were undertaken to define the mechanism by which O2 alters pulmonary antibacterial activity. Normal and BCG pretreated rabbits were exposed to 100% O2 for 24, 48, and 72-h periods. Pulmonary alveolar...
