Effect of Shuangjinlian mixture on oral ulcer model in rat.

To observe the effect of common clinical drug Shuangjin Lian mixture on rats with oral ulcer and discuss its mechanism.Sodium carboxymethyl cellulose caused leukocyte aggregation in rats, observed the anti-inflammatory effect of Shuangjin mixture. 3 mm * 3 mm size ulcer surface in the oral cavity of rats was caused by 90% phenol solution, to observe the therapeutic effect and anti-inflammatory effect of Shuangjinlian mixture on rats with oral ulcers.

The low, middle and high dose Shuangjinlian mixture can inhibits the accumulation of white blood cells caused by sodium carboxymethyl cellulose in rats significantly (P < 0.01). And reduce the degree of edema and hyperaemia around the ulcer tissue significantly (P < 0.01), improve the ulcer healing probability, and reduce the level of TNF-α, VEGF levels and increase IL-2 level in the serum of rats with oral ulcers significantly (P < 0.01). Pathological examination showed that the lesion of ulcer tissue in each treatment group was obviously alleviated.

Shuangjinlian mixture had anti-inflammatory effect and was effective for the prevention and treatment of oral ulcer in rats.
