The mesothelium and its reactions: a review
The origins, nature, and reactions of the mesothelium have intrigued investigators for over 100 years. Recently, the use of sophisticated techniques has clarified earlier impressions of its development, structure, and function. The structure of mesothelium reflects…

Immunocytological staining reactions of anti-carcinoembryonic antigen, Ca, and anti-human milk fat globule monoclonal antibodies on benign and malignant exfoliated mesothelial cells
This laboratory study tested whether three antibody stains could help tell mesothelioma apart from lung cancer and from benign conditions, using cells shed into body-cavity fluid (pleural or peritoneal effusions). The stains detected…

Characterization of the bronchoalveolar cellular response in experimental asbestosis. Different reactions depending on the fibrogenic potential
This was an animal experiment in male Wistar rats. Each rat received a single injection into the windpipe of saline (control), 5 mg of UICC chrysotile B asbestos, or 5 mg of very short 4T30 chrysotile fibers. Lung washings (bronchoalveolar lavage)…

An investigation of the penetration of ingested asbestos into the normal and abnormal intestinal mucosa of the rat
…surviving amosite-injected rat, the injection sites showed granulomas: dense masses of macrophages holding crystals that looked like amosite under polarized light. The saline rat showed smaller reactions of a different kind. Second, five healthy rats…

Cooperative stimulation by sulfite and crocidolite asbestos fibres of enzyme catalyzed production of reactive oxygen species
…plus the chemical EDTA produced 2160 pmol of ethylene, against 683 pmol for EDTA alone and 29 pmol for crocidolite alone. The authors stated that these model reactions are no proof of reactions in the body.

Asbestosis and systemic lupus erythematosus
…as they knew, no such case had been described before. They suggested it could be a particular expression of immune reactions reported in many asbestos workers, possibly analogous to Caplan-Collinet syndrome (silicosis with rheumatoid arthritis).

Outcome of asbestos exposure (lung fibrosis and antinuclear antibodies) with respect to skin reactivity: an 8-year longitudinal study
…Among the 52 men who did respond, 2 did. Workers with ANA more often had weak skin reactions, and this was only partly explained by asbestosis cases. Smoking habits did not differ between responders and nonresponders…

Asbestos inhalation and the induction of splenic lymphocytic proliferation in the rat
…The authors concluded that asbestos inhalation produced two distinct effects on the macrophages, one attributed to a putative asbestos-related neoantigen. They suggested immune reactions might contribute to asbestosis. The number of rats was not reported.

Effects of informing workers of their health risks from exposure to toxic materials
…definitely should be told. The authors concluded that informing workers carried little risk of mental distress, and suggested that information alone was not sufficient to change smoking behavior. The study could not assess short-term reactions.

Cytokine regulation of lung fibroblast proliferation. Pulmonary and systemic changes in asbestos-induced pulmonary fibrosis
…later loss of the blood-cell inhibitor may be a consequence or amplifier of fibrosis. They noted that, given the injection method, their data do not relate to very early reactions to low-level inhaled asbestos.

The follow-up study of skin reactivity to recall antigens and E- and EAC-RFC profiles in blood in asbestos workers
We have determined cutaneous DTH reactions to SK-SD and PPD and peripheral blood lymphocyte profiles in a group of asbestos workers in two consecutive surveys. It was found that asbestosis and, to a lesser extent…

Comparative epidemiology of men exposed to asbestos and man-made mineral fibers
Comparative analyses are presented of selected studies of long-term reactions to occupational exposures to asbestos and man-made mineral fibers (MMMF), with emphasis on studies with dose-response information and long enough period of follow…

Tobacco-borne siderophoric activity
…Indeed, elements in tobacco smoke and asbestos synergistically damage DNA through reactions mediated by the (probably iron-dependent) formation of hydroxyl radical. These considerations prompted the hypothesis that tobacco smoke might contain substances capable of "delocalizing…

Biochemical components of bronchoalveolar lavage in early experimental asbestosis of the sheep: phospholipase A2 activity, prostaglandin E2 and proteins
…significantly increased in both low and high dose groups. These changes in protein and lipid components of BAL following asbestos exposure constitute early indices of lung inflammatory reactions which may contribute to the development of asbestosis.

Asbestos-related increase in pulmonary levels of vasoactive intestinal peptide (VIP)
