T cell subpopulations in the parenchyma in the different lobes at 7 weeks post injury were assessed on histological sections with antibodies raised against the respective antigens using a horseradish peroxidase based detection system. Counts expressed as cells per mm2 of parenchyma . The number of (a) CD4+ and (b) CD8+ Cytotoxic T cells helper cells in the bleomycin-treated lobes was not significantly different from the saline–treated lobes
