Apoptosis in rat lungs and apoptotic index. Cell death in rat lungs (n = 6) assessed by TUNEL staining. (A) PBS-treated control; (B) HUVEC-immunized; (C) Intrathymically HUVEC-injected and HUVEC-immunized; (D) Pristane-treated 3 days prior to HUVEC-immunization. (E) The apoptotic index (%) was calculated as the ratio of TUNEL-positive cells to total lung cells. Magnification x400. *p < 0.05 compared to control and each of tolerized rat groups.
