Popis: | BACKGROUND Chyle fat transplantation has shown positive effects on preexisting human hypertrophic scars (HSs) in a nude mouse HS graft model. METHODS Hypertrophic scar fragments were obtained from 5 surgically treated burn patients and implanted into the backs of nude mice in 3 groups: group A, control; group B, triamcinolone; and group C, chyle fat. The specimens were implanted after the corresponding intralesional injection in each group, and the mice were observed for 4 weeks. In total, 18 mice and 72 scar specimens were studied. After 4 weeks, the HSs were removed from the mice. Then, the scar weights, histology, and decorin staining were assessed to evaluate the therapeutic efficacy. RESULTS An obviously significant difference was observed in the HS weight reduction between groups A and C (P < 0.01), and a significant difference in the HS weight reduction was observed between groups A and B (P < 0.05). However, there was no significant difference between groups B and C. The treatment groups (groups B and C) showed strong decorin staining. Furthermore, the decorin staining was much stronger in group C than in group B (P < 0.05). Significant differences in extracellular matrix deposition were observed among the 3 groups, as determined by Masson trichrome staining. Both groups B and C showed significant therapeutic efficacy compared with group A, and group C exhibited a significant therapeutic effect compared with group B (P < 0.05). CONCLUSIONS This study indicates that chyle fat grafting is beneficial for treating HSs. |
