| 摘 要： | 本文用透明、软X线造影及组织学切片技术,对100例家兔左心空壁内动脉进行了观察,并与人心左室壁内动脉作了比较讨论。家兔左心室壁内动脉的分布类型在许多方面与人的相似。分枝型动脉(ClassA血管)供应心肌全层,包括心内膜下层;直型动脉(ClassB血管)主要分布到乳头肌、肉柱。乳头肌肉动脉分布可分为节段型、轴型和混合型。室间隔左心室侧壁内动脉分布比较紊乱,无明显规律。在心脏横切面中,毛细血管与心肌纤维方向平行,呈袢状分布。

The Intramural Arterics in the Left Ventricle of the Rabbit Heart |
| |
| Abstract: | The normal arterial patterns in the left ventricle wall of 100 rabbithearts were studied by the methods of postmortem coronary angiogram, theclearing method and histological section, compared with that of the humanheart. The intramural arterial patterns in the left ventricle of the rabbitheart are similar to those of the human heart. "Branching" type arteries(Class A vessels) supply the whole of myocardium, including the subendoca-rdial zone, while "straight" type arteries(Class B vessels)mainly supply thepapillary muscle and trabeculae carneae where they form the subendocardialplexus. The arterial type in papillary muscles may be classified intosegmental pattern, axial pattern and mixed pattern. The arterial distributionof the left ventricular side in the interventricular septum is ruleless. Thecappillaries in all areas run parallel with the myocardial fibres and showthe crosscorexions somewhere. |
