Factors of Serumal Estrogen Increasing in Infant with Hemangiomas and Its Relationship with Tumors' Proliferation / 实用儿科临床杂志

Objective To explore the factors of high level of serum estradiol(E2)in infant with hemangiomas and its relationship with tumors' proliferation.Methods The levels of serumal estradiol of 25 proliferative hemangiomas and 15 oblique inguinal hernias with same ages 1 day preoperation and 3 days postoperation were tested by chemiluminescence enzymatic immune method.The expressions of estrogen receptors(ER)in 25 tumors and 15 normal skin tissue were tested by immunohistochemical method.Results The levels of E2 of preoperation were ob-viously higher than that of postoperation in hemangiomas and control group(Pa0.05).The expression of ER in tumors was significantly higher than that in normal skin tissue(P
