title: [Experiment of effective components from traditional Chinese herbs on ischemic left ventricular remodeling].
abstract: OBJECTIVE
  To investigate the effects of effective components extracted from medicines compatibility on ischemic myocardial remodeling.
  
  
  METHODS
  The animal models of ischemic myocardial remodeling was copied by ligating the left anterior descending branch of coronary artery in rat. And then decoction and effective components extracted from the same medicines were administrated to rats. The heart function was detected by ultrasound diagnostic apparatus and the heart morphology was examined by Hematoxylin and Eosin, picrosirius staining respectively on the 3rd and 56rd day.
  
  
  RESULTS
  Both concentrated decoction and effective components compatibility showed good restrained effects on ventricle malignant remodeling, such as improved heart function, reduced the area of myocardial infarction, lowered heart index, mitigated the fibrosis level and decreased apoptosis cell numbers in infarction and non-infarction areas. The difference were statistically significant when compared with the control group (P < 0.01, P < 0.05), and effective components treated group had better effects than concentrated decoction group (P < 0.05). Concentrated decoction group showed little effects on the 3rd day, while effective components group showed significant effect (P < 0.05).
  
  
  CONCLUSIONS
  Effective components compatibility has better effects on inhibiting the process of ischemic myocardial remodeling than concentrated decoction. Effective components compatibility has better effects on ventricle malignant remodeling by eliminating the interfrence non-pharmacodynamic elements of the medicine.
