THE LYMPHATIC VESSELS OF THE SINU-ATRIAL (SA) node were investigated after injection of Indian ink plus gelatine in 62 canine and 31 human hearts, the latter of subjects aged between 21 and 80. Lymph was found to be chiefly drained from the SA node of the dog by a vessel which collected lymph near the left margin of the SA node and ran between the superior vena cava and the right circumference of the aorta into the left cardiac lymph collector and through it into the left cardiac node. Approximately in two thirds of cases this main lymph drainage was supplemented by smaller lymphatic branches running into the right traceo-bronchial nodes. In man, the main route of lymph drainage from the SA node is represented by one or two vessels which run to the right and upwards along the superior vena cava into the inferior tracheo-bronchial nodes (of the bifurcation), lying near the right bronchus. Little branches draining lymph into the cardiac collector are found rarely. It has become evident from histological sections that the lymphatic vessels run between the cells of the conduction system and the collagenous fibres of connective tissue and are not numerous.
在62只犬和31颗人心脏（后者来自年龄在21至80岁之间的受试者）中注射印度墨水加明胶后，对窦房（SA）结的淋巴管进行了研究。发现犬的SA结主要通过一条血管引流淋巴，该血管在SA结左缘附近收集淋巴，在上腔静脉和主动脉右缘之间走行，进入左心淋巴收集器，并通过它进入左心淋巴结。大约三分之二的病例中，这条主要的淋巴引流途径由汇入右气管支气管淋巴结的较小淋巴管分支补充。在人类中，SA结的主要淋巴引流途径由一两条血管代表，它们沿着上腔静脉向右上方走行，进入位于右支气管附近的下气管支气管淋巴结（分叉处）。很少发现有小分支将淋巴引流到心脏收集器。从组织学切片中可以明显看出，淋巴管在传导系统的细胞和结缔组织的胶原纤维之间走行，数量并不多。
