　　The results of researching on the laboratory for Biochemistry, physic-biology: Acupunctural analgesia (a/a) helps increase the pain-threshold through the increasing
　　 dosage of β--endorphinernia (before a/a; 35.58±10.50pg/ml; after a/a:46.25 ±11.42Pg/ml p<0.001), acetylcholinema (before a/a:l.841±0.459 μmol/L;after
　　a/a:4.910± 2.053μ mol/L p<0.001), carccholaminemia (before a/a:0.085±0.017mol/L; after a/a: 0.181±0.25mol/L p<0.001), Acupunctural analgesia is shown the electrical activity of the brain that the increase of the percentage of the Q -waves and D -waves and decrease the low 6 -waves this is the quite useful to the process of controlling the painful preventive of the human body.
