Results: In hemangioma at proliferating phase, hemangioma at involuting phase, and normal skin, the expressions of TRAIL were 1.26±0.56, l.74±0.68, and 1.00±0.23, PI was (40.98±12.02)%,(20.05±3.67)% and (15.64±4.01)%, AR was (11.96±4.02)%,(20.29±3.53)% and (6.61±1.29)%, respectively. There were significant differences among the 3 groups in the 3 parameters.
