摘要: 目的 探讨电磁脉冲 (EMP)辐照对大鼠血清部分生化指标和左心室肌损伤的影响.方法 48只雄性SD大鼠随机分为正常对照组和EMP辐照组,每组24只.EMP辐照组在锥形平板GTEM小室内接受200 kV/m 的EMP辐照,正常对照组进行假辐照.各组于辐照后12、24、48、96 h,采用全自动生化检测仪检测血清钾离子(K+)、钠离子(Na+)、谷氨酸转氨酶(ALT)和天冬氨酸转氨酶(AST)的含量;同时取左心室肌制备电镜超薄切片,应用透射电镜观察心肌超微结构的改变.结果 EMP辐照组与正常对照组相比血清K+、Na+浓度于辐照后24 h显著下降(P<0.05);ALT含量分别于辐照后12、24、48 h显著升高(P<0.01,P<0.05),96 h恢复;AST含量分别于辐照后12、24、48、96 h显著升高(P<0.01, P<0.001).EMP辐照后12 h心肌超微结构即发生改变,24 h变化最为明显,主要表现为肌浆网扩张,线粒体肿胀,嵴排列紊乱、减少甚至空泡化,闰盘间隙增宽.48 h较24 h明显好转,96 h已基本恢复正常. 结论 EMP辐照可造成大鼠K+、Na+、ALT及AST含量异常,心脏组织超微结构可复性损伤.

Abstract: Objective To explore the changes of serum biochemical indexes and characteristics of ventricular myocardium injuries in rats exposed to electromagnetic pulse (EMP) irradiation. Methods A total of 48 male SD rats were randomly divided into control group (n=24), and EMP irradiation group (n=24) which was exposed to EMP irradiation (200 kV/m). The right atrium blood was obtained 12, 24, 48, and 96 h after the rats were irradiated. The K+, Na+, ALT and AST levels were analyzed by coulter automatic biochemical analyzer. All rats were sacrificed and the left ventricular myocardia were collected for observation under transmission electron microscope. Results The levels of K+ and Na+ markedly decreased 24 h after EMP irradiation (P<0.05). The level of ALT significantly increased 12, 24, and 48 h after irradiation, and returned to normal 96 h after irradiation (P<0.01, P<0.05). The level of AST remarkably increased 12, 24, 48 and 96 h after irradiation (P<0.01, P<0.01). Ultrastructure of left ventricular myocardium obviously changed 12 h after irradiation and the changes reached the peak 24 h after irradiation, which were characteristic of dilatated sarcoplasmic reticulum, swollen mitochondria with cristae loss and vacuolization, and broadened space between intercalated. These changes improved 48 h after irradiation, and disappeared 96 h after irradiation. Conclusion EMP can cause K+, Na+, ALT and AST turbulence, and reversible injury of ventricular myocardium in rats.
