Fig. 1 Semiquantitative RT-PCR analysis of vIL-10 mRNA transgene expression in rat lung allografts. The peak areas of bands were expressed as a relative ratio of vIL-10/glyceraldehyde-3-phosphate dehydrogenase (GA3PDH). The gel image shows vIL-10 bands from groups 1 and 2 but not from group 3. The relative ratio of vIL-10/glyceraldehyde-3-phosphate dehydrogenase in group 1 was significantly higher than that in group 2 (P =.0050 vs group 2). Values are means ± SD of 6 or 7 animals per group. PC, Positive control.

Fig. 2 Immunohistochemistry for transgene vIL-10. Transgene vIL-10 protein was detected by means of immuno-histochemistry in bronchial endothelial cells, alveolar epithelial cells, and alveolar macrophages. (Original magnifications: A, 200×; B, 200×; C, 400×; D, 400×.)

Fig. 3 Histologic rejection score. The sections were graded separately for both acute vascular rejection (A-score) and airway rejection (B-score). The acute vascular rejection score in group 1 was significantly lower than that in group 3 (P =.042 vs group 3, Kruskal-Wallis test). There were no significant differences (NS) in airway rejection scores. Bars show median values.

Fig. 4 Arterial blood oxygen tension (PaO2). PaO2 obtained 5 minutes after right hilar crossclamping is shown. Each PaO2 in groups 1 ( ± mm Hg) and 2 ( ± 35.7 mm Hg) was significantly higher than that in group 3 (66.4 ± 8.22 mm Hg; P =.020 and P =.023 vs group 3). Values are means ± SD of 6 or 7 animals per group.

Fig. 5 Exhaled NO levels from rat lung allografts. Exhaled NO levels in group 2 (5.150 ± 6.38 ppb) were significantly lower than those in group 3 ( ± 10.4 ppb; P =.020 vs group 3). Exhaled NO levels in normal lungs (NL ; 0.00 ± 0.0 ppb) were significantly lower than those in groups 1 and 3 (*P <.005, respectively). Values are means ± SD of 5 to 7 animals per group.

Fig. 6 Semiquantitative RT-PCR analysis of IL-2 mRNA expression in rat lung allografts. The peak areas of the bands were expressed as the relative ratio of IL-2/glyceraldehyde-3-phosphate dehydrogenase (GA3PDH). IL-2 mRNA expression in group 1 and in normal lungs was significantly lower than that in group 3 (P =.039 and P =.0014 vs group 3). IL-2 mRNA expression in group 2 was lower than that in group 3, trending toward significance (P =.068 vs group 3). Values are means ± SD of 6 or 7 animals per group.

Fig. 7 RT-PCR analysis for mRNA expression of tumor necrosis factor (TNF) α, iNOS, IFN-γ, and endogenous IL-10 in rat lung allografts. Normal lung (NL) mRNA expression in these cytokines was significantly lower than that in other groups (*P <.05, respectively). There were no significant differences between groups 1, 2, and 3. Values are means ± SD of 4 to 7 animals per group. GA3PDH, Glyceraldehyde-3-phosphate dehydrogenase.
