耳针的应用早就受到重视

对多种疾病的临床观察已肯定了耳针的疗效。采用耳压法治疗胆石症也有显著的临床效果

近年来的病例日益增多。然而

several ultrastructural parameters of Gray's type I synapses in nucleus originis dorsalis nervi vagi were abservcd and quantitati- vely analysed by use of electron microscopy in condition gallbladder coniraction by stimulating the auricular liver-gall act

oint of rabbits with electrode. It was found that the synaptic contact length was increased extremely significantly

and the postsynaptic thickening length lengthened significantly. There were no changes in the area and the perimeter of presynaptic bouton as well as synaptic vesicle density. The percentages of synaptic perforation and negative synaptic interface tended towards increase. But there were no differences in synapses of positive and straight interface. It is suggested that the nucleus isinvoived in the regulation of gallbladder activity induced by auricular acupoint stimulation.
