目的

探讨苦参碱生物粘附凝胶对口腔溃疡的疗效。

方法

将36只家兔分为模型组、空白凝胶组、苦参碱凝胶组,每组各12只。采用冰醋酸化学烧灼法建立口腔溃疡模型,空白凝胶组和苦参碱凝胶组家兔分别在溃疡处敷上空白凝胶和苦参碱凝胶,模型组仅在溃疡处冲洗生理盐水。分别于用药后的2、4、9、12 d计算溃疡面积,随后分批处死,取口腔黏膜进行病理学观察及评分。

结果

给药后4 d,苦参碱凝胶组家兔的溃疡面积显著小于模型组及空白凝胶组[(0.15 ± 0.02)、(0.28 ± 0.03)、(0.25 ± 0.01)cm2F = 31.821,P < 0.05],而给药后2、9、12 d时,三组溃疡面积比较,差异均无统计学意义(F = 4.856、3.321、3.233,P均> 0.05)。组织病理学显示,用药后4 d,模型组、空白凝胶组家兔口腔黏膜上皮炎症细胞浸润较为严重,伴有出血、坏死,苦参碱凝胶组家兔炎症细胞浸润较轻,成纤维细胞出现较多;用药后12 d,三组家兔炎症都有明显好转,且苦参碱凝胶组上皮表面不完全角化,与正常组织形态基本一致。同时,苦参碱凝胶组家兔用药后4、9 d病理学评分较模型组、空白凝胶组均显著提高[(3.00 ± 0.00)、(2.00 ± 0.00)、(2.33 ± 0.47)分,F = 13.525,P < 0.05;(4.33 ± 0.94)、(2.67 ± 0.47)、(3.33 ± 0.47)分,F = 6.251,P < 0.05]。

结论

苦参碱生物黏附凝胶对家兔口腔溃疡具有良好的治疗及改善作用。

Objective

To investigate the effect of matrine bioadhesive gel for oral ulcer in rabbits.

Methods

A total of 36 rabbits were randomly divided into three groups: model group, blank gel group and matrine gel group, 12 rabbits in each group. The chemical burning method with acetic acid was used to establish the oral ulcer model. Rabbits in the blank gel group and matrine gel group were given blank gel and matrine gel on oral ulcer, respectively, and rabbits in the model group only received saline flush on oral ulcer after model established. The ulcer area was calculated on 2, 4, 9, 12 d after treatment, then all the rabbits were sacrificed respectively. The oral mucosa was taken to pathological observation and pathological score at the same time.

Results

The ulcer area in the matrine gel group were much smaller than those in the model group and blank gel group on 4 d after treatment [(0.15 ± 0.02), (0.28 ± 0.03), (0.25 ± 0.01) cm2, F = 31.821, P < 0.05], and the ulcer area among the three groups showed no significant differences on 2, 9, 12 d after treatment (F = 4.856, 3.321, 3.233, all P > 0.05). Histopathological examination revealed that inflammatory cell infiltration, and with hemorrhage and necrosis in the model group and blank gel group, and inflammatory cell infiltration a very mild and fibroblasts appeared in the matrine gel group on 4 d after treatment; On 12 d after treatment, the inflammation had improved markedly among the three group, and the mucosa in the matrine gel group recovery much better. Meanwhile, the pathological scores in the matrine gel group on 4, 9 d after treatment were much better than those in the model group and blank gel group [(3.00 ± 0.00), (2.00 ± 0.00), (2.33 ± 0.47), F = 13.525, P < 0.05; (4.33 ± 0.94), (2.67 ± 0.47), (3.33 ± 0.47), F = 6.251, P < 0.05].

Conclusion

Matrine bioadhesive gel can improve the recovery of oral ulcers in rabbits.
