However, the main side effect of PDT is long term skin photosensitivity after the treatment because of the slow elimination of hematoporphyrin derivative from the skin. For solving this problem, 21 PWS volunteers accepted a new photosensitizer hematoporphyrin monomethyl ether in the treatment. 26 lesions ...

为解决治疗后的较长时间皮肤光敏反应这一主要副作用，本文对21例志愿鲜红斑痣患者的26个病灶应用血啉甲醚为光敏剂进行了治疗，对HMME的作用进行了临床观察，发现HMME具有良好的疗效、较轻的局部反应、较短的避光期和可行重复治疗的间隔期等优点，值得对其进行深入的研究。
