Effect of thymol on superoxide anions generation. Cells with various concentrations of thymol (50, 100 and 150 μM) were incubated in flat bottom microtiter plates for 24 h. After incubation period nitroblue tetrazolium dye reduction assay was done. Stimulation index was calculated. Results are depicted as the mean ± standard error of the mean (SEM). Statistical significance was calculated using the Students t-tests. * represents P-value < 0.05.
