Microscopic examination,bacterial culture,SOD and MDA examination were conducted just before and after the procedure. Results No cure was observed in each group.18 patients were improved in group A,15 in group B,21 in group C and 2 in group D. The efficacy rate was 47.3%,46.8%,65.6% and 13.3% respectively. Compared to the placebo group, the free-radical scavenger had a significant therapeutic efficacy and had no significant difference to the antibiotic group and ?-blocker group.
