[Origin of nitric oxide synthase positive nerve fibers at zusanli area in rats].
OBJECTIVE
To find the origin of nitric oxide synthase (NOS) positive nerve fiber at the area around Zusanli point(St. 36).


METHODS
The combined method of retrograde transport of horse radish peroxidase and nicotinamide adenosine dinucleotide phosphate diaphorase were adopted.


RESULTS
Some peripheral processes of NOS positive neurons were distributed in the Zusanli point from the ganglia of L4 to S1, and some were projected from the lamina IX of L4 to S1 in spinal cord.


CONCLUSIONS
The distributions of NOS positive nerve fibers in the, Zusanli area might be one of the morphological foundations of acupuncture effect of Zusanli point.
