Effects of acetaminophen on melanin contents of rat CYP2E1-TG larvae. EGFP fluorescence-negative (EGFP [−]) and -positive (EGFP [+]) F2 CYP2E1-transgenic larvae were exposed to 2.5 mM acetaminophen (APAP) from 24 hpf to 54 hpf for determination of melanin contents. Control means no treatment since APAP was dissolved in ZR solution. Each tube contained 18–20 larvae, and the melanin contents of three tubes were determined for each treatment (n = 3). Bars with different letters (a, b) are significantly different (p < 0.05). Inset images in the right are also shown. Asterisk indicates mild pericardial edema in inset image.
