Effects of N-acetyl-cysteine and acetylsalicylic acid on the tonsil bacterial biofilm tissues by light and electron microscopy.
2014
OBJECTIVE : The present study aimed to investigate the effects of the bacterial biofilm formation on the tonsil surface exposed N-acetyl-cysteine (NAC) and acetylsalicylic acid (ASA) of patients undergoing tonsillectomy by light and electron microscopy. The general process of biofilm formation comprises adhe - sion of free-living or planktonic bacteria to a sur - face, which subsequently develop into micro - colonies and form a biofilm. Based on studies that have shown the presence of biofilms in common sites of chronic infections, it has be - come clear that bacteria may persist on mucosal surfaces through formation of biofilms. PATIENTS AND METHODS: Ten patients be - tween 4 and 39 years of age (mean, 11.9 ± 11.2 years). In all cases, periodic acide Schiff (PAS) staining was found to be an accurate predictor of the presence or absence of biofilm using light microscopy as a control standard. Therapeutic doses of NAC and ASA were identificated as the effective on the tonsil bacterial biofilm using light and electron microscopy. RESULTS: Biofilm formation was detected on all samples. Tonsils removed from patients with ASA-10 had showed higher-grade inhibitory ef - fect at the biofilm formation than the other group (p ≤ 0.0001). The correlation was found between drug dose and decrease at the biofilm formation. CONCLUSIONS: In chronic or recurrent tonsil - litis patients, decrease on the tonsils surface biofilm formation may be associated with ASA dose. Whether effect on the tonsils surface biofilm formation of other agent have a role is not known.
