Representative 1D 1H-NMR spectra of perchloric acid extracts from rat spinal dorsal horn.

A representative NMR spectrum is displayed for samples extracted from control rats fed with a normal diet (normal diet - CT) (bottom panel, black), oxaliplatin-treated rats fed with a normal diet (normal diet - OXA) (middle panel, dark grey) and oxaliplatin-treated rats fed with a PDD (PDD - OXA) (upper panel, light grey). Chemical shifts are expressed in parts per million (ppm). Eighteen metabolites were identified and quantified (Ace, acetate; Ala, alanine; Asp, aspartate; AXP, adenosine phosphates; BHB, β-hydroxybutyrate; Cho, choline; GABA, γ-aminobutyric acid; Gln, glutamine; Glu, glutamate; GPC, glycerophosphocholine; Lac, lactate; MyI, myo-Inositol; NAA, N-acetylaspartate; NAAG, N-acetylaspartylglutamate; PC, phosphocholine; PtC, phosphatidylcholine; Succ, succinate; tCr, total creatine).
