Abstract

The extracellular fluid space in rabbit SA node and atrial trabeculae was measured with 14C-inulin and 14C-sucrose. A larger 14C-inulin space in SA node than in the atrial tissue, indicated a greater extracellular fluid space in the former, and could be due to caveolae on the pacemaker cell membrane.

摘要

用14C-菊粉和14C-蔗糖测量了兔窦房结和心房小梁的细胞外液空间。窦房结中14C-菊粉空间比心房组织中的大，这表明前者的细胞外液空间更大，可能是由于起搏细胞膜上的小窝。
