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.
