大鼠循经低阻线的形态学特征(初步报道)

<正> 前文已经报道大鼠的体表也和人类相似,存在经脉循行线。本文应用组织学和生物物理学相结合的方法,初步证明在这条循经的低阻线下,大鼠皮肤在毛囊和神经血管的分布方面具有形态学特征。实验用大白鼠,雌性、体重250～350克。毛囊观察组动物22只。取材前,先依前文测出背部膀胱经和腿部、腹部胃经的低阻线,分别用炭素墨水标记。然后在乙醚麻醉下断头处死。取材时,用锐刀切取宽为沿低阻线两侧3毫米,长为7毫米的皮肤块,尽可能连同皮下组织和肌肉取下,放在冰托

MORPHOLOGICAL CHARACTERISTICS OF THE LOW IMPEDANCE LINE ALONG MERIDIAN OF RAT

Low impedance lines (LIL) along meridian of urinary bladder and stomach were mapped and marked with carbon ink on the skin of normal rats. After sacrificed, samples of skin, together with subcutaneous tissues and muscles were cut, frozen-sectioned and observed under microscope for the hair follicles distributed under LIL and its adjacent areas. Other samples were fixed, embedded and stained with hematoxylin eosin for nerve bundles and blood vessels examination. It was found that there was an abundance of nerve bundles and blood vessels and a tendency of lack of hair follicles under the LIL in comparison with its adjacent areas.
