MethodsTo study the SEP with the BL-420 biological signal collecting system. The cerebral cortex tissues were extracted, homogenized and centrifuged. Na+-K+ATPase activity was measured with ATPase analytical kit. Results After intracerebroventricular injection with OFQ 0.9 ?g, the amplitude of P1-N1 and N1-P2 increased significantly(P
