硫柳汞對(duì)秀麗隱桿線蟲(chóng)神經(jīng)行為及生長(zhǎng)發(fā)育的影響
[Abstract]:Objective to investigate the neurodevelopmental toxicity of thiomersal to nematode by studying the effect of thiomersal on the nerve behavior and growth of nematode larvae. Methods the 50% lethal concentration (LC50) of nematode was measured after exposure to 0 ~ 140 渭 mol/L or 0 ~ 5 渭 mol/L thiomersal for 48 h, and the effects on motor behavior, perceptual behavior, feeding behavior and growth and development (body length, body width) of nematode were investigated. Results compared with the solvent control group, the movement behavior (head swing and body bending), perceptual behavior (trend and avoidance) and feeding behavior (pharyngeal pump vibration) of nematode larvae significantly changed after exposure to thiomersal for 48 h (P0.05). In addition, thiomersal significantly inhibited the growth and development of nematode, and the inhibition was dose-effect. Conclusion thiomersal has adverse effects on nervous behavior, growth and development of nematode larvae, and the toxic mechanism of thiomersal needs further study.
