摘　　要：为了阐明金钱豹(Panthera pardus)和猪獾(Arctonyx collaris)心冠状动脉的分支分布特征及血供情况,为心脏生物学及动物学研究提供结构基础资料,利用血管铸型和组织透明方法观察研究了金钱豹与猪獾心左、右冠状动脉的分支分布。结果表明,金钱豹和猪獾的心均由左右冠状动脉营养。金钱豹左冠状动脉分为室间隔支、前降支和旋支。前降支又分出左室上支、左室中支和左室下支。右冠状动脉沿途分出右室前支、右室后下支和右室后上支。猪獾左冠状动脉分为前降支和旋支。前降支又分出室间隔支和左室前支,旋支又分出左缘支和左室后支。其右冠状动脉沿途分出右室前支、右缘支和右室后支。金钱豹和猪獾心的室间隔均由发自左冠状动脉的独立的室间隔支营养,二者左右冠状动脉在膈壁的分布属于均衡型。In order to know the blood supply features and branch characteristic of coronary artery in the heart of Panthera pardus and Arctonyx collaris and to provide the structural basis for heart biology study, we observed the branches and distribution of the coronary arteries in P. pardus and A. collaris by arterial vascular casting and tissue transparance method. The results showed that the nutrition of P. pardus and A. collaris heart was all supplied by left and right coronary arteries. The left coronary artery of P. pardus was divided into interventricular septal branch, anterior descending branch and circumflex branch. Anterior descending branch gave off superior branch of left ventricle, midterm branch of left ventricle and below branch of left ventricle. The right coronary artery of P. pardus was divided into anterior branch of right ventricle, posterior below branch of right ventricle and posterior superior branch of right ventricle. The left coronary artery of A. collaris was divided into anterior descending branch and circumflex branch. Anterior descending branch gave off interventricular septal branch and anterior branch of left ventricle, circumflex branch gave off left fringe branch and posterior branch of left ventricle. The right coronary artery of A. collaris was divided into anterior branch of right ventricle, right fringe branch and posterior branch of right ventricle. The interventricular septum of P. pardus and A. collaris was all supplied by an independent interventricular septal branch that was from the left coronary artery. The distribution type of left and right coronary arteries on the diaphragmatic surface in P. pardus and A. collaris heart is the balance circulation type.
