Histologic rejection score of lung allografts. (a) Group A (antileukinate early administration, white bar) and Cont-A (vehicle, black bar). (b) Group B (antileukinate continuous administration, shadow bar) and Cont-B (vehicle, black bar). There is significant difference in histologic rejection score between B and Cont-B group (2.1 ± 1.0 vs. 3.3 ± 0.5, P = 0.018). The value is expressed as mean ± standard deviation. *Significant difference (P = 0.018) in comparison with vehicle group.
