Four groups, a sham operation group, a normal control group, a model group and an auricular acupuncture group were set up. After acupuncture was given at auricular points, Brain and Kidney. Immunohistochemical analysis, behavioural observation and computer image analysis were made.\nRESULTS: Auricular acupuncture could decrease significantly the beta-amyloid protein (A beta) immunoreactivive neurons and increase its average optical density in the parietal cortex of the VD rats (P \u003c 0.05).\nCONCLUSION: Auricular acupuncture can reduce or inhibit the over-production of Abeta in the brain, so as to improve the learning and memory capacity of the VD model rat."}
