IL-1ß, IL-6 and TNF-α expression levels of macrophage cells induced by benzydamine hydrochloride, benzydamine hydrochloride with chitosan, calcium hydroxide and chlorhexidine medicaments: An ELISA study

Abstract

The aim of the present study was to evaluate IL-1ß, IL-6 and TNF-α expression levels of macrophage cells induced by benzydamine hydrochloride (BNZ), BNZ with chitosan, calcium hydroxide (CH) and chlorhexidine (CHX) medicaments. Half maximal inhibitory concentrations (IC50) were assessed on THP-1, Saos-2, and CRL-2014 cells using MTT assay. THP-1 cells were differentiated into macrophages with phorbol12-myristate13-acetate and activated with lipopolysaccharide. IL-1β, IL-6 and TNF-α levels in supernatants were determined using enzyme-linked immunosorbent assay (ELISA). The data were examined with one-way ANOVA and Tukey's multiple comparison test (p=0.05). At the selected concentrations, the cell viability was higher than 50% for chitosan and CH, whereas CHX presented lower IC50 values than BNZ and BNZ+chitosan. According to ELISA results, the lowest IL-1β, IL-6 and TNF-α values were observed with BNZ+Chitosan 50 µg/mL and BNZ 50 µg/mL. BNZ+chitosan 50 µg/mL combination has revealed promising anti-inflammatory effects. Nevertheless, these findings need to be examined in clinical conditions.
