间使穴为手厥阴心包经的穴位

位于前臂掌面的下段。针灸学简编中认为在腕上三寸

掌长肌健与桡侧腕屈肌腱之间

“主治突然心痛

心悬如饥”

此外对中风、癫狂及小儿惊厥、精神病等亦可治疗。王雪苔著的针灸学手册认为除治心区痛等病证外尚可治疗急性心包炎、小儿夜啼、神经性呕吐及慢性低热等症。由于间使穴是手厥阴心包经的主穴

又具有可以主治心痛及心10 cats were used in the present experiments. 60μl of 15-20% HRP wasinjected into the left nerve trunks of point "Jianshi" and right point "Jianshi". After 5 days of survival the heart was perfused with 1% para- formaldehyde and 1.25% glutaformal dehyde in 0.1M phosphate acid buffered at PH 7.4. the sixth cervical to second thoracic spinal ganglions (G_6-T_2) were cut and treated according to Edward (79) O-D and Mesulam TMB method

and the reactions were made out. In the seventh to eighth cervical spinal ganglions and first thoracic s- pinal ganglions HRP labeled cells (C7-8

T1) were found. Most of them were present in C8 and T1

while in C7 labeled cells were less. The large

middle and small labeled cells coexisted. In the efferent neurons of the anterior horn of C8-T1 spinal cord

we also fotind the labeled cells. The essential afferent neurons of point "Jianshi" located in the C7-T1 spinal ganglions. It is different from the location of the afferent neurons of the median nerve (C5-T1). This study has proved the segmenta1 distri- butions of afferent neurons of the heart and "Jianshi" point are overlappe- d. This overlap may be the morphologic foundation for the treatment of heart diseases by acupuncturing "Jianshi" Point.
