摘要: 目的 以斑马鱼胚胎及幼鱼为实验对象,研究氟[18F]脱氧葡糖注射液(FDG)中工艺引入杂质三甲基硅醇对斑马鱼胚胎及幼鱼的影响,以评估其毒性。方法 采用体视光学显微镜观察给予三甲基硅醇后斑马鱼胚胎及幼鱼的发育情况,包括致畸和致死检测;应用斑马鱼行为轨迹跟踪系统评价三甲基硅醇对斑马鱼幼鱼自主行为的影响。结果 三甲基硅醇可剂量依赖性地降低斑马鱼胚胎及幼鱼的存活率,增加畸形率;不仅可显著抑制胚胎卵黄囊吸收和幼鱼浮漂生长,还能引发胚胎和幼鱼围心囊水肿,此外还可显著导致幼鱼行为活跃。结论 三甲基硅醇对斑马鱼胚胎及幼鱼表现出显著的发育毒性和心脏毒性,还对幼鱼表现出一定程度的神经毒性,应在FDG产品中对其进行严格控制。

Abstract: Objective To explore the toxicity of trimethylsilanol, which is an impurity introduced into fludeoxyglucose [18F] injection, on zebrafish embryos and larvae. Methods The development of zebrafish embryos and larvae exposed to different concentrations of trimethylsilanol was observed by stereomicroscopy, involving teratogenic and lethal detection. The trajectory tracking system for zebrafish behavior was used to analyze the influence of trimethylsilanol on autonomous behavior of larvae. Results Trimethylsilanol led to a dose-dependent decrease of survival of zebrafish embryos and larvae, induced an increase in deformity and edema of pericardial sac in both embryos and larvae, inhibited embryo yolk sac absorption and larvae floating growth, and activated the behavior of larvae. Conclusion Trimethylsaline has not only significant developmental and cardiac toxicity on the embryos and larvae of zebrafish, but also some neural toxicity on the larvae.
