Fig. 8. Effect of tannic acid (TA) on intestinal barrier in diquat-induced mice. CON, control mice; DIQ, diquat-treated mice; LTA, mice pretreated with 2.5 mg kg⁻¹ TA and treated with diquat; MTA, mice pretreated with 5 mg kg⁻¹ TA and treated with diquat; HTA, mice pretreated with 10 mg kg⁻¹ TA and treated with diquat; (A)–(C) the gene expression of claudin, zonula occludens 1 (zo-1), occludin in jejunum. Values are expressed as mean ± SEM, n = 10. ^a,bMeans of the bars with different letters were significantly different among groups (P < 0.05).
