摘要: Abstract Peripheral blood T lymphocytes from patients with idiopthic pulmonary fibrosis and matched normal controls were examined for their helper function in an vitro antibody synthesis assay. This assay measures the dose-related T-cell regulation of production by B cells presence pokeweed mitogen. Eight 14 expressed significantly increased activity, three exhibited no change, had depressed function. All excessive active neutrophilic alveolitis as determined bronchoalveolar lavage on day study. Five studied to have a low percentage neutrophils (
