    Key words: Acupuncture; Immune response

    The purpose of this study was to assess the effect of acupuncture on the immunological response. The induction of anti-sheep red blood cells(SRBC) plaque-forming cells (PFC) was used as a measurement o f the immune response to treatment. In normal no n-immunized mice, enhancem entof PFC was seen after a single acupuncture treatment when spleen cells from sti mulated mice were cultured with SRBC in vitro. Aft er 3 acupuncture

    treatments, spleen cells from mice did not show PFC enhancement after treatment with anti-Thy-1.2 antibody an d complement, nor aft er the removalof non-adh erent cells. Serum obtained from mice I h after acupuncture stimulation enhanced the PFC of normal spleen cells in vitro, but the enhance-ment was abolished by the addition of propranolol. These results suggest that acupuncture, by activation of the autonomic nervous system,modulates the immune response.

    Recen t r epor t s have sugges ted tha t the immune reac -t ion is regulated by the centra l nervous system [4, 8] .This is in teres t ing to note , as exper imental s tudies havea l so shown tha t acupun c tu re s t imula t ion a ffec ts the ac -t ivi ty of several systems within the brain and induces there lease o f endo genou s op io ids [11].
