Objective:
To determine bacteriostatic abilities ofArtemisia argyi extracts,and to explore the effect ofArtemisia argyi extracts on oral ulcer in rats.Methods:
We extracted the mixture ofArtemisia argyi volatile oils and water-extraction by leaching method and evaluated the anti-microbial effect ofArtemisia argyi extracts on common oral floras in vitro.The rat cheeks were burnt by NaOH to establish the models of oral ulcer.The curative effects of crude drug of Artemisia argyi extracts at 2.0,1.0,0.5 g/mL on oral ulcer in rats were evaluated by measuring the oral ulcer healing time.Serum TNF-α level and expression of proliferating cell nuclear antigen (PCNA) were analyzed by ELASA and immunohistochemical staining.Results:
Artemisia argyi extracts obviously inhibited the Staphylococcus aureus and Streptococcus.NaOH-made oral ulcer in rats were successfully established.The crude drug at 2.0 and 1.0 g/mL obviously reduced healing time,significantly inhibited the release of TNF-α,and improved the PCNA level in the ulcer tissues (All P＜0.01).The extracts obviously reduced the local inflammatory reaction and promoted tissue repair of oral ulcer.Conclusion:
Artemisia argyi extracts promote tissue repair of oral ulcer via inhibiting bacterial growth,reducing the release of TNF-α and improving the PCNA level.
