Comparison of stimulation indices (S.I.) of BALF cells (A) and splenic cells (B) in response to MP extracts between model D (□) and model E (■). Cells were obtained at 96 h post-IT (A), 6 days after the last IP (B) on each experiment respectively. The S.I. was calculated as the ratio of ³H-thymidine uptake of cells incubated with MP extracts to that incubated without MP extracts. Non immunized mice group was noted as “Cont” in (B).
