摘要:

目的 建立呋喃丹的家兔灌胃染毒致死模型,观察呋喃丹Ⅱ相代谢物呋喃酚葡萄糖醛酸结合物(carbofuran-7-phenyl glucuronic acid,Glu-7PH)在家兔体内的死后分布及死后再分布规律。 方法 死后分布:对家兔使用1/2LD50、LD50、2LD50呋喃丹灌胃染毒,染毒死亡家兔立即解剖,灌胃后2 h仍未死亡家兔采用二氧化碳(CO2)吸入法处死后立即解剖,取心肌、心血、肝、脾、肺、肾、脑和右下肢肌肉。死后再分布:家兔用4LD50呋喃丹灌胃染毒,仰卧位置于室温(15 ℃)条件下,分别于死后0、12、24、48、72 h取心肌、心血、肝、脾、肺、肾、脑和右下肢肌肉。采用液相色谱-串联质谱(liquid chromatography-tandem mass spectrometry,LC-MS/MS)法检测Glu-7PH含量。 结果 死后分布结果显示,3个剂量组中,各组织中Glu-7PH含量差异存在统计学意义。死后再分布研究结果显示,心血、心肌、脾、肾、脑及右下肢肌肉中Glu-7PH含量差异无统计学意义,肝、肺中Glu-7PH含量差异存在统计学意义。 结论 家兔心肌、心血、肝、肺、肾、脑和下肢肌肉可作为Glu-7PH检测分析样本。Glu-7PH在家兔肝和肺中存在死后再分布现象。

Abstract:

Objective To establish a carbofuran intragastric administration death model in rabbits, and to observe the postmortem distribution and postmortem redistribution of carbofuran-7-phenyl glucuronic acid (Glu-7PH) in rabbits. Methods The postmortem distribution: Rabbits were given an administration of 1/2LD50, LD50, 2LD50 carbofuran. Dead rabbits were dissected immediately. Rabbits that had remained alive 2 hours were sacrificed by carbon dioxide (CO2) inhalation and dissected immediately. The myocardium, cardiac blood, liver, spleen, lung, kidney, brain and right hindlimb muscle were collected. The postmortem redistribution: After giving an administration of 4LD50 carbofuran, the myocardium, cardiac blood, liver, spleen, lung, kidney, brain, and right hindlimb muscle were collected at 0, 12, 24, 48, and 72 h postmortem in supine position at 15 ℃ room temperature. The quantity of Glu-7PH was determined by LC-MS/MS. Results The postmortem distribution: Among the three dose groups, there were significant differences in the quantities of Glu-7PH in different tissues. The postmortem redistribution: There was no significant difference in the Glu-7PH quantities in cardiac blood, mycardium, spleen, kidney, brain and right hindlimb muscle, but there was a significant difference in the Glu-7PH quantities in the liver and lung. Conclusion The mycardium, cardiac blood, liver, lung, kidney, brain and hindlimb muscle of rabbits can be used as appropriate samples for Glu-7PH detection. However, it should be noted that Glu-7PH was redistributed postmortem in rabbit liver and lung.
