摘要: 目的 用大鼠脏器组织探索微波辐射透射电镜生物样品的超快制样方法,寻找适合本实验室条件的微波照射使用范围,以适应临床诊断工作的需要。方法 取大鼠的肝,肾,心,肺,脾,胰等脏器,按微波照射时间和功率不同分为微波1组、2组、3组,对样品进行快速制备,观察微波辐射后各组细胞器超微结构的保存结果,以选择最佳微波照射使用范围。结果 三个微波组各脏器细胞超微结构在原位都能很好保存,超微结构清晰,境界分明,其中以微波2组效果最佳,各脏器细胞超微结构与常规组无明显差异;微波1组肝和心脏线粒体有轻度膨胀外,其它脏器细胞超微结构完好;微波3组肝、肾、心脏器的部分细胞器略显微波损伤。结论 微波照射使电镜生物样品制备时间大大缩短,由原来一周缩短到一天,并能良好地保持组织细胞的超微结构,得到清晰的图像,该微波仪可使用微波范围较广,重复性好,应用于电镜标本快速制备是可行的,缩短了临床病理电镜诊断的时间。

Abstract: Objective To establish the rat model of Multiple Organ Dysfunction Syndrome (MODS) caused by trauma. Method Sixty SD rats were divided randomly to MODS model group and control group. The rats of the MODS model group were scalded at 30% TBSA Ⅲ degree and injected with large amount of LPS 6 hour later. The mortality in 7 days, the blood ALT,CK,BUN, fasting glucose and TNFa, NO, IL-6 of MODS rats were observed or determined. Results The mortality in 7 days of the MODS rats was 53.33%. The blood ALT, CK, BUN, fasting glucose and blood TNFa, NO, IL-6 of the MODS rats were higher than that of the control. Conclusion Serious scalded rats with large amount of LPS injected can represents a characters of MODS.
