Effect of 72 h of INH exposure on zebrafish hepatotoxicity. (A) Liver morphology from zebrafish larvae. Liver degeneration is indicated by a red circle. (B) Green fluorescence-labeled liver morphology. (C) Change in liver size. (D) Change in liver fluorescence intensity. (E) Morphology of liver pathological sections (HE staining). (F and G) ALT and AST levels. *, P < 0.05; **, P < 0.01 (both, versus results for the control); #, P < 0.05; ##, P < 0.01 (both, versus results in the absence of LPS).
