ObjectiveTo study the relationship between expression of Caspase-3 and regression of hemangioma. MethodsCaspase-3 expression was detected in 79 hemangiomas and 5 normal skin tissues by immunohistochemistry (SP). ResultsIn 79 hemangiomas, the positive rates of Caspase-3 expression in proliferating, involuting and involuted phases were 52.4%, 91.2% and 83.3%, respectively. The expression of Caspase-3 in involuted and involuting phases was higher than proliferating phase(P lt;0.05,P lt;0.01) and control group(P lt;0.01). There was no statistical difference between the latter two groups (P gt;0.05). ConclusionCaspase3 is involved in the converting of hemangiomas from proliferating phase into involuting phase. The activation of Caspase-3 may induce apoptosis of endothelial cells, thus leading to the regression of hemagioma.
