Influence of needling at yin-yang meridian points on cerebral glucose metabolism

[Guest guest]

Hi All,

 

Here's more fuel for the debate on the

existence/non-existence of specific AP points and

meridians. This study, which was just indexed on

Medline, compared changes in cerebral glucose

metabolism (as evidenced in PET scans) of subjects

being needled on Yin and Yang meridians, respectively.

They found substantially different effects for the two

groups:

[influence of needling at yin-yang meridian points on

cerebral glucose metabolism] [Article in Chinese] Dong

JC, Li J, Zuo CT. Affiliated Huashan Hospital to Fudan

University, Shanghai 200040. OBJECTIVE: To study the

different effect of needling at different meridian

points (MP) on different cerebral functional regions by

using positron emission tomography and cerebral

function tracer 18F-fluorodeoxy glucose to observe the

effect of electro-acupuncture (EA) stimulation at Yin

MP or Yang MP on local cerebral glucose metabolism in

30 healthy volunteers. METHODS: The thirty subjects

were randomly divided into 2 groups, the 12 subjects in

the Yang MP group treated by needling at Hegu (LI4),

Quchi (LI11), Zusanli (St36) and Shangjuxu (St37), the

18 subjects in the Yin MP group treated by needling at

Neiguan (Pc6), Chize (Lu5), Sanyinjiao (Sp6) and

Yinlingquan (Sp9). All the needling was conducted at

one side of body. RESULTS: After needling at Yang MP,

the cerebral glucose metabolism was elevated in

bilateral cross region of frontal lobe and temporal

lobe, parietal lobe, thalamus and basal ganglia, and in

contralateral cerebellum and hippocampus. After

needling at Yin MP, the cerebral glucose metabolism was

lowered in bilateral cross region of frontal and

temporal lobe, contralateral temporal lobe, cerebellum

and thalamus, and was elevated in homolateral

hippocampus and caudate nucleus. CONCLUSION: Under

physiological condition, the regulatory effects of

acupuncture on central nervous system would be

different when needling at different MP. PMID: 12585145
