Quantification of substance P (SP) labeling after saline and cisplatin (ip) injections in the spinal cord substantia gelatinosa and dorsal vagal complex (area postrema, nucleus of the solitary tract, and dorsal motor nucleus). A) Study 2, effects of saline or 20 mg/kg cisplatin. Tissues were collected at 6 or 72 h after injection. B) Study 3, effects of saline and 30 mg/kg cisplatin. Tissues were collected at 72 h after injection. Data are shown as box and whisker plots with the median, 1st and 3rd quartiles, and whiskers representing 1.5 times the inter-quartile range. A scatterplot of all values is overlayed.
