One of the options for the treatment of periodontitis is local drug delivery systems (LDD). Tulsi (Ocimum sanctum), a traditional herb, has many uses in medicine. It could be a suitable agent as LDD for the treatment of periodontitis.
The aim was to formulate, evaluate the anti-inflammatory activity; assess duration of the action and the efficacy of 2% tulsi (O. sanctum) gel in the treatment of experimental periodontitis in Wistar Albino rat model.
Thirty six Wistar albino rats were randomly assigned to 3 groups. Periodontitis was induced using ligature model. Group 1-control; Group 2-Plain gel and Group 3-2% tulsi (O. sanctum) gel.
2% tulsi (O. sanctum) gel were prepared. The anti-inflammatory activity and duration of action were assessed. Silk ligature 5-0 was used to induce periodontitis. Gingival index (GI) and probing pocket depth were measured. Treatment was done. The rats were sacrificed. Morphometric analysis was done using Stereomicroscope and ImageJ software.
ANOVA followed by Bonferroni's test, Wilcoxon's test for intergroup comparison, Mann-Whitney test for P value computation was used. The observations are mean ± standard deviation and standard error of the mean. P < 0.01 as compared to control was considered as statistically significant.
2% tulsi (O. sanctum) gel showed 33.66% inhibition of edema and peak activity was noted at 24 h. There was statistically significant change in the GI and probing pocket depth. Morphometric analysis did not show any significant difference between groups. No toxic effects were seen on oral administration of 2000 mg/kg of Tulsi extract.
2% tulsi (O. sanctum) gel was effective in the treatment of experimental periodontitis.
治疗牙周炎的方法之一是局部药物递送系统(LDD)。传统草药罗勒(神圣罗勒)在医学上有多种用途。它可能是一种适合作为局部药物递送系统用于治疗牙周炎的药物。
目的是制备、评估2%罗勒(神圣罗勒)凝胶的抗炎活性;评估其作用持续时间以及在Wistar白化大鼠模型中治疗实验性牙周炎的疗效。
36只Wistar白化大鼠随机分为3组。采用结扎模型诱导牙周炎。第1组为对照组;第2组为普通凝胶组;第3组为2%罗勒(神圣罗勒)凝胶组。
制备2%罗勒(神圣罗勒)凝胶。评估其抗炎活性和作用持续时间。使用5-0丝线结扎诱导牙周炎。测量牙龈指数(GI)和探诊深度。进行治疗。处死大鼠。使用体视显微镜和ImageJ软件进行形态计量分析。
采用方差分析(ANOVA),随后进行Bonferroni检验、组间比较的Wilcoxon检验、计算P值的Mann-Whitney检验。观察结果为均值±标准差和均值标准误。与对照组相比,P<0.01被认为具有统计学意义。
2%罗勒(神圣罗勒)凝胶显示出33.66%的水肿抑制率,在24小时时达到峰值活性。牙龈指数和探诊深度有统计学显著变化。形态计量分析未显示组间有任何显著差异。口服2000mg/kg罗勒提取物未见毒性作用。
2%罗勒(神圣罗勒)凝胶对实验性牙周炎的治疗有效。
