摘要 The objective of this study was to investigate the embryotoxicity of diclofenac. Zebrafish (Danio rerio) embryos at 12 hpf were treated with different dosages of diclofenac (0–2,000 ppm) for different time courses (12–72 hr). Results showed no evident differences in survival rates or morphological changes between the mock-treated control (0 ppm) zebrafish embryos and those with 1-ppm diclofenac-exposure (12–24, 12–36 hpf). In contrast, after higher doses (5 and 10 ppm) of exposure, embryos displayed some defective phenotypes, including malformed somite boundary, a twisted body axis, and shorter body length. In addition, diclofenac-treated embryos exhibited significantly reduced frequencies of spontaneous in-chorion contractions in comparison with mock-control littermates (mock-control: 13.20±2.24 vs. 5–10 ppm diclofenac: 6.66±1.35–3.03±1.84). Subtle changes were easily observed by staining with specific monoclonal antibodies F59 and phalloidin to detect morphological changes in muscle fibers and formation of F-actin, respectively. Our data show that diclofenac treatment disturbs actin organization and muscle fiber alignment, thus causing malformed somite phenotypes.
