Résumé
OBJECTIVE: To investigate the stimulation effect of several bacterial inhibitors of eye drops on eyes.METHODS: Stimulation effect of several bacterial inhibitors on rabbits eyes were observed with the contrast on the same body.The scores were counted according to the score standard of eyes stimulation response in order to evaluate the stimulation effect of bacterial inhibitors.RESULTS: After giving single dose of inhibitors,the average scores of stimulation reaction induced by 0.002% thiomersal,0.01% benzalkonium chloride,0.01% benzalkonium bromide,0.01% chlorhexidin acetas,0.5% chlorobutanol,0.03% ethylparaben,2% boric acid were 0.20,0.32,0.36,0.60,1.20,3.88,6.32,mild stimulation reaction was induced by 2% boric acid and 0.03% ethylparaben and others inhibitors caused no stimulation response.After giving multiple doses of inhibitors,the average scores of above inhibitors were 0.49,0.79,0.84,3.83,3.91,6.51,10.84,the medium stimulation reaction was induced by 2% boric acid,mild stimulation reaction were induced by 0.03% ethylparaben,0.01% chlorhexidin acetas and 0.5% chlorobutanol;0.002% thiomersal,0.01% benzalkonium chloride,0.01% benzalkonium bromide caused no stimulation reaction.CONCLUSION: The best inhibitors of eye drops are thiomersal,benzalkonium chloride,benzalkonium bromide,followed by chlorhexidin acetas,ethylparaben,chlorobutanol.
