The Effects of Topical Ketamine Gel on Saliva and Serum Level of Interlukin-6 in Patients with Recurrent Aphthous Ulceration
Abstract
Aims: To evaluate the effect of topical application of ketamine gel )0.5%( and gel alone)without ketamine( on salivary and serum level of human interlukin-6)IL-6 (in patient with recurrent aphthous ulceration )RAU( and compare the results with control group having no RAU. Materials and methods: The investigation was carried out on)36( subjects with mean ± SD ages )25.11±6.31(years and different sex )20 males,16 females(. These subjects were divided into three groups. Group1: The study group consisted of )12(patients having minor RAU received topical ketamine gel )0.5%( applied on the lesion. Group2: The placebo group consisted of )12(patients having minor RAU received topical gel alone. Group3: The control group consisted of )12( healthy subjects having no RAU.Peripheral venous blood and saliva samples were collected from all subjects before treatment, and four days after treatment from group1and group2 only, to assess the levels of serum and salivary )IL-6( by Enzyme Linked Immuno Sorbent Assays )ELISA( method. Patients were subjectively assessed for the intensity of pain which was recorded pre and four days post treatment in group1 and 2 by using Verbal Pain Scale )VPS(. Data were analyzed using paired t-test, One way ANOVA and Willcoxon Signed Ranks test. Results: The results showed that the mean of serum IL-6 concentrations were high in the study and placebo groups )18.49±5.4pg/ml( and )18.97± 7,47 pg/ml( respectively before treatment comparing with mean of serum IL-6 concentration of control group )9.63±2.77pg/ml(, and the mean of salivary IL-6 concentrations were high in the study and placebo groups )63.03±47.28pg/ml( and )62.25±45.14pg/ml( respectively before treatment comparing with mean of saliva IL-6 concentration of control group )13.1±5.08pg/ml(.
