Vagotomy reduced cisplatin-induced kaolin intake. A. Twenty four hours kaolin intake in the first day after cisplatin (6mg/kg) injection. EA (20Hz, 0.6ms, continuous) could reduce kaolin intake in the first day after injection. Subdiaphragmatic vagotomy significantly reduced rat 24 hours kaolin intake. After vagotomy, EA has no further effect on kaolin intake. Compared with Cisplatin: ** < 0.01, # < 0.001. B. EA reduces delayed emesis (the second day kaolin intake), independent of vagal pathway. Vagotomy had no effect on the second day kaolin intake. Compared with Cisplatin * < 0.05.
