ABSTRACT
Objective To observe the efficacy of No. 1 Baiban granules in the treatment of vitiligo using skin confocal laser scanning microscopy. Methods The study was approved by the hospital ethics committee. Nine-two patients with qi stagnation and blood stasis were collected from Department of Dermatology of the Affiliated Hospital of Tianjin Academy of Traditional Chinese Medicine and were randomly assigned to two groups. The experimental group (n=49) received oral Baiban granuleΙ, 3 g, twice a day, transfer factor capsules 6 mg, 3 times a day, 0.1%mometasone furoate cream (excluding the face) for external use, once a day, or 0.1%tacrolimus ointment (Afacial), twice a day for 3 months. The control group (n=43) only received oral transfer factor capsules 6 mg, 3 times a day, 0.1%mometasone furoate cream (except for the face) for external use, once a day, or 0.1%tacrolimus ointment (face), twice a day, treatment for 3 months. The therapeutic effect was observed in two groups. CLSM was used to monitor the compound color and pigment recovery level, and changes of the number of dendritic cells and inflammatory cell infiltration in skin. Results The compound color was improved significantly after treatment in experimental group and control group. The total effective rate was higher in experimental group than that of control group (81.63% vs. 69.77%,χ2=3.947,P<0.05). Results of CLSM observation showed that the pigment recovery of skin lesion, the proportion of dendritic cells and inflammatory cells were significantly higher in experimental group than those of control group (P < 0.05). Conclusion The treatment effect of No. 1 Baiban granules is more obvious for vitiligo of qi stagnation and blood stasis.
