Objective:To study the relatively-specific correlation be tween Foot-Yangming Mer idian and the stomach. Methods:45 rabbits anesthetized with ure thane were random ly divided into normal saline (NS) group

atropine model group

electroacupu ncture (EA) of Foot-Yangming Meridian [“Zusanli”(ST 36)

“Tianshu”(ST 25)

“Li angmen”(ST 21) and “Sibai”(ST 2)] group

Foot-Shaoyang Meridian [“Yang lingq uan”(GB 34)

“Daimai”(GB 26)

“Riyue”(GB 24) and “Yangbai”(GB 14)] group and Foot-Taiyang Meridian [“Chengjin”(BL 56)

“Cuanzhu”(BL 2)

etc.] gro up

with 9 rabbits in each group. After EA treatment

the rabbit’s gastric antrum m uscle was taken to be incubated

and centrifuged for isolating smooth muscle cells

a nd then the cells were fixed with 2.5% glutaraldehyde and mounted to glass slice s. The cell length was detected under light microscope and the cellular contract ion percentage was calculated after treatment with atropine. Results:After treatment with atropine

the smooth myocyte length of atr opine model group (63.26±6.62 μm) was significantly larger than that of NS gro up ( 56.8 6±7.37 μm

P<0.05); while in comparison with model group

the cellular length of EA-Foot-Yangming group (39.16±2.33 μm) was obviously shorter (P<0 .01). No significant differences were found between model group and EA-Foot-S hao yang ( 59.63±8.31 μm)

and between model group and EA-Foot-Taiyang group (58.41 ± 6.42 μm). Findings indicated that after administration of atropine

the g astr ic smooth myocytes were in relaxation state

after EA of acupoints of the Stomac h Meridian of Foot-Yangming

they were activated to induce contraction via sup pr essing M-receptor

suggesting that there exists a relatively specific correlat io n between Foot-Yangming Meridian and the stomach. Conclusion: Puncturing acupoin ts of Foot-Yangming Meridian can cause the smooth myocytes of rabbit gastric a ntrum to produce contraction.
