目的:研究蒙药匝迪阿瓦治疗应激性心肌损伤的作用机制。方法: 将Wistar 大白鼠随机分成三组:
正常对照组、制动冰泳组和匝迪治疗组，分别用HE 染色法光镜观察心肌组织病理变化、ELISA 法检测血清中肌
钙蛋白I( cTnI) 、肿瘤坏死因a( TNF－a) 、白细胞介素6( IL－6) 的含量、用TUNEL 法检测心肌细胞凋亡。结果: 制
动冰泳组大鼠心肌损伤明显，心肌细胞凋亡显著，血清中cTnI、TNF－a、IL－6 的含量增加( P＜0． 01) ; 匝迪治疗组
心肌损伤较轻，心肌细胞凋亡较少，血清中cTnI、TNF－a、IL－6 的含量减少( P＜0． 01) 。结论: 蒙药匝迪阿瓦可能
通过抑制TNF－a、IL－6 的释放，减轻炎症反应，减少心肌细胞凋亡，从而减轻大鼠心肌损伤。

Objective: To study the effective mechanism of the Mongolian nutmeg on stress －
induced myocardial injury． Methods Wistar rats were randomly divided into three groups: control
group，braking and ice swimming group and nutmeg treatment group． Pathological changes of myocardium
were observed with the HE staining under the light microscopy． Troponin I ( cTnI) ，tumor necrosis
factor a ( TNF－a) and interleukin－6 ( IL－6) levels were detected by ELISA in serum． Cardiac
myocyte apoptosis was detected by TUNEL assay． Ｒesults Compared with normal control group，myocardial
injury and cardiomyocyte apoptosis are both increased significantly in braking and ice swimming
group，and the contents of cTnI，TNF－a，IL－6 are also increased in Serum( P＜0． 01) ． However，
Compared with braking and ice swimming group，myocardial injury and cardiomyocyte apoptosis are
less in nutmeg treatment group，and the contents of cTnI，TNF－a，IL－6 are also decreased in Serum
( P＜0． 01) ． Conclusion stress －induced myocardial injury may be related with myocardial apoptosis
mediated by the inflammatory mediators tumor necrosis factor－a，IL－6． Moreover，Mongolian nutmeg
had protective effects on stress－induced myocardial injury by reducing tumor necrosis factor－a，IL－6，
and inhibiting cardiomyocyte apoptosis．
