在高压下用Microfil（粘度约20 cP的硅橡胶弹性体）灌注犬、猫、兔、大鼠和豚鼠的后肢、下颌或舌头的横纹肌。勾勒出血管床的轮廓当材料凝固后，将肌肉固定在福尔马林中。通过改良的Gomori三色法对组织学切片进行检查，发现毛细血管中含有Microfil以及一些未灌注的红细胞。从灌注良好的肌束中，对每根肌纤维周围的毛细血管数进行计数，所有肌肉的毛细血管数从0到9不等，平均值在3.2到4.0之间。红肌和白色肌都是如此。共享一个毛细血管的纤维的平均数范围从2.0到3.2，较低的值被发现时，四个血管包围的纤维和较高的值时，只有三个。结果表明，从一个正方形阵列的纤维与每个毛细管之间的两个相邻的纤维到一个六边形阵列的毛细管在交替的顶点过渡模型的连续。
Striated muscles of hindlimb, jaw, or tongue in dogs, cats, rabbits, rats, and guinea pigs were perfused under high pressure with Microfil (a silicone elastomer of viscosity 20 cP approx.) to outline the vascular bed. When the material had set, the muscles were fixed in formalin. Exmination of histological sections, strained by a modified Gomori trichrome method, showed capillaries containing Microfil as well as some, unperfused, filled with red cells. From well-perfused bundles the numbers of capillaries surrounding each fiber were counted; in all muscles these ranged from 0 to 9 with mean values betweeen 3.2 and 4.0. This was true of both red and white muscle. The mean number of fibers sharing one capillary ranged from 2.0 to 3.2, the lower value being found when four vessels surrounded a fiber and the higher value when there was only three. The results indicate a continuum of transitional models from a square array of fibers with each capillary between two adjacent fibers to a hexagonal array with capillaries at alternate vertices.
