Characters of the populations were studied with Q-type Hierarchical Clustering Method. The elevation and average annual rainfall were found to be important characters. The ecology factor is also an important character for the breed classification.展开更多

Hematoxylin-eosin staining was conductedfor comparison. The results showed evident loss of CK-MM,CK-BB, myoglobin and myosin from cardiac muscle cells, indi-caring that occurrence of SNDS is closely associated withacute myocardial ischemia.展开更多
