Fig. 7. Effect of halothane on macrophage inflammatory protein-2 (MIP-2) mRNA expression in alveolar type II cells. (A ) Southern-blot analysis of MIP-2 cDNA after reverse-transcription polymerase chain reaction. Results of one of four representative experiments. (B ) MIP-2 expression in alveolar type II cells expressed as MIP-2/S14 ratio. Results are expressed as mean ± SD; ‡P < 0.001 versus  air. bp = base pair; C = control group; MW = molecular weight.
