  • Objective : Recently, many studies have showed the evidences of the effect of the acupunture treatment through scientific methods. One of these methods is functional MRI. We performed electro-acupunture on Sp6 and observed the changes of brain activation using fMRI. Methods : To see the effect of electro-acupunture stimulation on Sp6, the experiment was carried out on 12 healthy volunteers, using the gradient echo sequence with the 3.0T whole-body MRI system(ISOL). After the needle insertion on right Sp6, 2Hz of electric stimulation was given for 30 seconds, repeated five times, with 30 seconds' intervals. The Image analysis including motion correction, talairach transformation, and smoothing was done with SPM99. Results : 1. Group averaged brain activation induced by bilateral eletro-acupunture stimulation on Sp6 activates Brodman Area 3, 7, 13. 2. Group averaged brain deactivation induced by bilateral eletro-acupunture stimulation on Sp6 activates Brodman Area 6, 38, 47. 3. Group averaged brain activation induced by unilateral(right side) eletro-acupunture stimulation on Sp6 activates Brodman Area 5, 6, 13, 17, 18, 19, 31, 38, 40 ptoms, back pain(32.5%) was the 4. Group averaged brain deactivation induced by unilateral(right side) eletro-acupunture stimulation on Sp6 activates Brodman Area 3, 4, 18, 21, 36, 38, 39. 5. Brain region activated by motor stimulation activates Brodman Area 3, 4, 6, 18, 19.

  • Objective : The aim of the study is to investigate the effect of electro-acupuncture (EA) on ST36 to modulate immune reaction in BALB/c mice immunized intraperitoneally with 2,4-dinitrophenylated keyhole limpet protein(DNP-KLH). Methods : Experimental mice were divided into four groups : 1) Normal group was not performed by any operation. 2) IM(Immunized) group was immunized intraperitoneally with DNP-KLH and aluminum hydroxide without electro-acupunture stimulation. 3) IM-EA(immunized-elctro- acupuncture) group was performed by successive electro-acupuncture on the ST36 acupoint after immunization. 4) IM-NA(immunized-naloxone) group was performed by immunization and electro-acupuncture with same method, but naloxone was injected intraperitoneally 30 minutes before eletro-acupuncture to inhibit the opiate receptor in spleen. Serum total immunoglobulin I(IgE) and antigen-specific IgE was measured in each group. The expression of interferon-${\gamma}$ and interleukin-4 mRNA in spleen was researched by real-time RT-PCR Results : Serum total-IgE and antigen-specific IgE were significantly decreased only in IM-EA group. The expression of interleukin-4 in spleen cell was significantly reduced not only in IM-EA group, but also in IM-EA group. Conclusions : Above results indicate that the mechanism of immunomodulatory effect of electro-acupuncture is related to opioid system especially in B-cell immune reaction. Further research on the T-cell immunity is necessary to explain the mechanism of immunomodulatory effect of electro-acupuncture.
