The SPT paradigm: Rats that underwent CUMS showing sharply decreased in sucrose consumption and the change cannot be self-healing. Rats treated by riluzole and acupuncture could rectify the declining of sucrose consumption. Rats in the riluzole group showed significant improvement at the 2^nd week, while acupuncture group improved in the 3^rd week. Sucrose consumption in the riluzole and acupuncture groups was nearly at the same level at the 3^rd week and both reached normal level at the 4^th week. * Means significant difference compared to normal group (P<0.05). ^# Means significant difference compared to model group (P<0.05).
