The purpose of this study is to investigate the effects of LS at injury site or acupoint on analgesic-associated approach behavior and determine whether opioid receptors in the anterior cingulate cortex (ACC) were involved. Methods The left hindpaw incision was established in rats. LS (10.6 μm) was performed at the ipsilateral (left) acupoint ST36 (Zusanli) or locally to the incision site. Characteristic guarding pain behavior was measured to assess incision-induced pain. A two-chamber conditioned place preference (CPP) paradigm was used to measure approach behavior induced by pain relief. To inhibit opioid receptors, naloxone was microinjected into the ACC before LS. Results A delayed analgesic effect (24 h after treatment) was induced in both the LS groups (ST36 and incision site) as compared with the sham control or model groups (p less then 0.05). An immediate (30 min after the end of the LS) decrease in guarding pain (p less then 0.001) and CPP for the LS chamber (p less then 0.001) were observed only in the ST36 LS group. The administration of naloxone in ACC inhibited the LS-induced analgesic effect and CPP (p less then 0.05). Conclusions Our results highlight the novel approach behavior of pain relief induced by 10.6-μm LS at ST36 in a rat model of incisional pain, and implicate ACC opioid receptor signaling in these actions.The blast fungus Magnaporthe oryzae (syn. Pyricularia oryzae) is a destructive plant pathogen that can infect about 50 species of both wild and cultivated grasses, including important crops such as rice and wheat. M. oryzae is composed of genetically differentiated lineages that tend to infect specific host genera. To date, most studies of M. oryzae effectors have focused on the rice-infecting lineage. We describe a clone resource of 195 effectors of Magnaporthe species predic
