Abstract | PURPOSE: To investigate the anti-inflammatory effect of topical application of Curcuma longa (C. longa) and Berberis aristata (B. aristata) aqueous extracts on experimental uveitis in the rabbit. METHODS:
Anterior uveitis was induced in rabbits by intravitreal injection of lipopolysaccharide from Escherichia coli after pretreatment with C. longa and B. aristata aqueous extracts. Subsequently, the anti-inflammatory activity of C. longa and B. aristata was evaluated by grading the clinical signs and histopathologic changes and estimating the inflammatory cell count, protein, and TNF-alpha levels in the aqueous humor. RESULTS: The anterior segment inflammation in the control group was significantly higher than in both the extract-treated groups, as observed by clinical and histopathologic grading. The inflammatory cell count in the control group was 30.75 +/- 7.33 x 10(5) cells/mL, whereas it was 2.39 +/- 0.59 x 10(5) (P < 0.001 vs. control) and 11.56 +/- 2.44 x 10(5) (P = 0.001 vs. control) cells/mL in the C. longa- and B. aristata-treated groups, respectively. The protein content of the aqueous humor was 18.14 +/- 4.98, 3.16 +/- 0.55 (P < 0.001 vs. control), and 8.24 +/- 1.42 (P < 0.01 vs. control) mg/mL in the control, C. longa-, and B. aristata-treated groups, respectively. The aqueous TNF-alpha level in the control group was 976.29 +/- 66.38 pg/mL and was 311.96 +/- 28.50 (P < 0.0001 vs. control) and 654.09 +/- 47.66 (P < 0.001vs. control) pg/mL in the C. longa- and B. aristata-treated groups, respectively. CONCLUSIONS: Topical instillation of aqueous extracts of C. longa and B. aristata showed potent anti-inflammatory activity against endotoxin-induced uveitis in rabbits.
