Abstract:

BACKGROUND: Traditional treatments for hypertrophic scars, such as surgical resection, steroid hormones, antimetabolite, immunosuppressants and radiotherapy, are prone to resulting in relapse or serious adverse effects that limit their clinical application. In recent years, extraction of Chinese medicine for invigorating blood circulation and eliminating stasis has made satisfactory progress in the treatment of hypertrophic scars, and causes little adverse reactions.
OBJECTIVE: To observe the effect of notoginseng glycosides on rabbit ear hyperplastic scar and mRNA expression of transforming growth factor beta 1 using histological staining and related gene detection methods.
METHODS: A rabbit ear model of hyperplastic scar was established. At 4 weeks after modeling, 24 model rabbits were randomly divided into three groups, eight rabbits in each group: notoginseng glycosides group, triamcinolone acetonide group (positive control group) and blank control group. Local administration was performed in the three groups, five times. Then, scar tissues were extracted and dyed with Van-Gieson staining and hematoxylin-eosin staining for observation of collagen fibers and fibroblasts. Expression of transforming growth factor beta 1 mRNA was detected suing reverse transcription-PCR method.
RESULTS AND CONCLUSION: The number of fibroblasts number in the scar was lower in the notoginseng glycosides group than the blank control group, but there was no difference between the triamcinolone acetonide group and notoginseng glycosides group. Collagen fibers arranged more regularly in the notoginseng glycosides group as compared with the blank control group, and there was also no difference between the triamcinolone acetonide group and notoginseng glycosides group. Expression of transforming growth factor beta 1 mRNA was significantly lower in the triamcinolone acetonide and notoginseng glycosides groups than the blank control group (P < 0.05). These findings indicate that notoginseng glycosides and triamcinolone acetonide can inhibit fibroblast over-proliferation and reduce the synthesis of collagenous fibers by reducing expression of transforming growth factor beta 1 mRNA, and thereby, the excessive hyperplasia of scar is inhibited.
