Özet
Purpose To investigate the inhibitory effect of topically administered azithromycin (AZM), and moxifloxacin (MXF) against tumor necrosis factor-a (TNF-alpha) production in a rat model of endotoxininduced uveitis (EIU). Methods Thirty-six Wistar albino rats were divided into 6 equal groups. Groups 1, 2 and 3 were determined as sham, control group for topical AZM application and control group for topical MXF application, respectively. Sterile saline, topical AZM 1.5%, and topical MXF 0.5% were instilled 5 times daily for totally 6 days on both eyes of the rats in Group 4, Group 5, and Group 6, before and after inducing EIU by intravitreal injections of lipopolysaccharide, respectively. At 24 h after intravitreal injections, aqueous humor was collected from both eyes of each rat for the assessment of TNF-a concentration. Also, density of nuclear factor kappa B (NF-kappa B) in ciliary body, and the number of cells infiltrating the posterior segment of EIU rat eyes was assessed in one eye of each rat. Results There was a significant reduction in mean aqueous humor concentration of TNF-alpha in EIU rats pretreated with topical AZM in comparison with those pretreated with sterile saline (139 +/- 38.6 in Group 4 vs. 72 +/- 12.6 in Group 5, p = 0.006). There was also a marked decrease in mean aqueous humor concentration of TNF-a in EIU rats pretreated with topical MXF (139 +/- 38.6 in Group 4 vs.86.1 +/- 35.5 in Group 6, p = 0.025). Also, evident suppressions were determined in mean density of NF-kappa B, and in mean number of cells in EIU rats pretreated either with topical AZM, or topical MXF. Conclusions Topically applied AZM or MXF may be beneficial in the suppression of TNF-alpha production in aqueous humor.
