Effects of Acupuncture On Immune Response in Mice

The effect of acupuncture points stimulation on the induction of plaque-forming cells (PFC) in spleen cells of BALB/c mice was investigated in vivo and in vitro tests. In in vivo experiment, mice were immunized with 2 × 10s sheep red blood cells (SRBC) and the PFC was markedly increased by daily (once a day for 4 days) acupuncture stimulation. The enhancement of PFC by acupuncture was completely blocked by preadministration of procain, hexamethonium, naloxone, propranolol, but not by phentolamine. The enhancement of PFC by acupuncture was also observed in spleen cells of non-immunoized mice when spleen cells of the acupunctured mice were cultured with SRB in vitro. The enhancement of PFC in spleen was observed after stimulation with acupuncture, and a similar effect was also found in bone marrow cells of normal mice, but not in thymic cells. The spleen cells of mice given acupuncture showed no enhancement of PFC after treatment with anti-Thy 1.2 antibody and complement. Furthermore, these helper T cells w...
