| 摘 要： | <正> 以前工作表明大鼠和人类相似,存在循经低阻抗线,而且这条线下神经束的分布显著多于非低阻抗区。本文用诱发萤光法初步观察了大鼠循经低阻抗线的肾上腺能神经末梢的分布。实验用大白鼠7只。先在戊巴比妥钠麻醉下测出背部“膀胱经”的低阻抗线。然后在颈动脉放血,复查低阻抗线并以炭素墨水标记。用于冰冷冻局部皮肤,深达肌层。用锐刀切取沿低阻抗线两侧3毫米、深达7～8毫米、长约1厘米的皮肤块。经恒冷箱切片后用dela Torre法诱发萤光,在Leitz萤光

PRELIMINARY OBSERVATION ON THE ADRENERGIC NERVE TERMINALS UNDER THR LOW IMPEDANCE LINE ALONG MERIDIAN OF RAT |
| |
| Abstract: | Low impedance line (LIL)along meridian of Urinary Bladder was mar- ked with carbon ink on the skin of normal rats. After sacrificed, blocks of tissues including skin together with subcutaneous tissue and mucles were cut and sectioned in a cryostat. The slides were treated with glyoxylic acid to induce catecholamine fluorescence and were observed under fluorescent mic- roscope. It was found that there were more adrenergic nerve terminals under the LIL in comparison with its adjacent areas by means of screw micro- meter eyepiece for measurement under microscope. |
