Pneumonitis
Definition:
(n.) Inflammation of the lungs; pneumonia.
Example Sentences:
(1) A constellation of histologic lesions was identified in brain (diffuse meningoencephalitis with bilaterally symmetrical thalamic necrosis), liver (pericholangiohepatitis), lung (pneumonitis), and spleen (lymphoid hyperplasia); this tetrad is apparently unique to this model system.
(2) Calves showing signs of pneumonia had low levels of IgG1 (45-5 per cent had less than 8 mg per ml compared with "now-pneumonic" calves which had relatively high levels (only 9.5 per cent had less than 8 mg per ml).
(3) Two-thirds of the respiratory infections occurred in the first 3 postoperative months and were generally localized processes (focal pneumonitis, nodule(s), abscess, or empyema).
(4) The causes of death were interstitial pneumonitis (CMV-associated, 2 pats.
(5) The conventional explanation for the high fatality rate due to cytomegalovirus (CMV) pneumonitis among allogeneic transplant recipients is that immunosuppression renders the host unable to control replication of this opportunistic agent.
(6) He is still well; however, interstitial pneumonitis, mild thrombocytopenia, and polyclonal hypergammopathy have persisted for 4 years.
(7) The criterion of efficacy was the ability of the vaccines to reduce the extent of pneumonic lesions in vaccinated as against unvaccinated control lambs.
