BACKGROUND:Conventional treatments for hypertrophic scars include excision, steroid hormones, anti-metabolite drugs, immunosuppressive agents and radiation therapy. Easy to relapse or serious reaction limits their clinical use. In recent years, application of calcium channel blockers in treatment of hypertrophic scars has made more good progresses, but little adverse reactions are obtained. OBJECTIVE:To explore the effects of calcium channel blocker trifluoperazine on hypertrophic scar of rabbit ears. METHODS:A total of 24 rabbits were enrol ed in this study. After 1 week of accommodation, models of rabbit ear scar were established in accordance with the method of Morris and Li et al. Rabbit models were randomly assigned to three group (n=8). At 30 days after model induction, when scar formed, trifluoperazine and triamcinolone acetonide groups received trifluoperazine and triamcinolone acetonide injection. Blank control group was left intact. Changes in hyperplastic scar, hypertrophic index, levels of matrix metal oproteinase-2, tissue inhibitor of metal oproteinase-2, transforming growth factorβ1,α-smooth muscle actin and proliferating cellnuclear antigen were compared and observed in each group. RESULTS AND CONCLUSION:At 10 and 20 days after treatment, in the three groups, skin bulge was visible in rabbit ears and no rabbit hair grew. Rabbit ears had obvious softening in the trifluoperazine group compared with the triamcinolone acetonide group, showing dark red. In the blank control group, rabbit ear scar was evident and showed red color. At 20 days after treatment, scar thickness and scar index were lower in the trifluoperazine and triamcinolone acetonide groups than in the blank control group. Matrix metal oproteinase 2 expression was significantly higher, but tissue inhibitor of metal oproteinase-2 and transforming growth factorβ1 levels were lower in the trifluoperazine and triamcinolone acetonide groups than in the blank control group. Results indicated that trifluoperazine obtained good proliferative effects on rabbit ear scar, and could decrease scar thickness.
