[Morphometric observation on the mast cells under the acupuncture meridian lines].

Observation of the number, distribution and characteristics of the mast cells under the low impedance acupuncture meridian lines of 19 amputated limbs of patients suffered from osteoblastoma and 21 rats was carried out microscopically after sectioned and toluidine blue stained. Results revealed that the number of the mast cell was more concentrate under the meridian lines in comparison with their control areas. The difference was significant. This experiment reflexed another aspect of the morphological basis of the biophysical nature of the acupuncture meridian.
