Effects of HMME-SDT on hypertrophic scar of rabbit ear / 中华医学美学美容杂志

ABSTRACT

Objective To observe the clinical efficacy of HMME-SDT therapy for the treatment of hypertrophic scar (HS) of rabbit ear.Methods 60 white rabbits were randomly divided into five groups.The model group and HMME-SDT treatment group were used to establish the models of hypertrophic scar in ears.Results The effect of HMME-SDT on the fibroblastic density in the hypertrophic scarring models was observed in rabbit ears.The HMME-SDT could lower the fibroblastic density,compared with the model group,with significant difference (P＜ 0.05).The effect of HMME-SDT on the collagen area density was noted in the hypertrophic scarring models in rabbit ears.The HMME-SDT could lower the collagen area density,compared with the model group,with significant difference from the fourth week of the epithelialization (P＜0.01).Conclusions HMME is an effective sonosensitizer.HMME-SDT can significantly inhibit hypertrophic scar of rabbit ear.
