Effect of Wenxin Granules on Gap Junction and MiR-1 in Rats with Myocardial Infarction

Figure 1

Heart preparation, echocardiography, electrocardiogram (ECG), and pathological sections from normal and MI rats. (a) Preparation of the hearts from the control group (a1) and the model group (a2). (b) Pathological section of the largest cross-section of the control group (b1) and the model group (b2). (c) Typical echocardiography images from the control group (c1) and the model group (c2). (d) Hematoxylin and eosin (HE) staining of myocardial tissue from the control group (d1) and the model group (d2). (e) Typical ECG recordings: the ECG of the model group before coronary artery occlusion surgery (e1); the ECG of the model group 30 minutes after surgery (e2); the ECG of the model group 24 hours after surgery (e3); and the ECG of the control group 24 hours after sham surgery (e4). (f) Comparison of ejection fraction (EF). (g) Comparison of infarct size. (A) Control group, (B) Model group, (C) Metoprolol group, (D) Low dose WXKL group, and (E) High dose WXKL group. Values are expressed as the mean ± SD. , versus the control group. , versus the model group.
