“The fractional inhibitory concentration index(FICI) of DHA combined with cefuroxime or ampicillin was 0.375 and 0.75, respectively, determined by checkerboard microdilution assay, suggesting the synergistic effect or additive effect of the drug combination.”
“Then we studied the synergistic mechanism of DHA combined with cefuroxime and found that the combination of the two drugs had a significant inhibitory effect on the total protein bands, as shown by the results of polypropylene gel electrophoresis.”
