FIGURE 2.

Whole-nerve responses to concentration series of NaCl or Glc and binary mixture of these compounds in the chorda tympani nerves of WT mice. Response to 0.1 mol/L NH₄Cl was used as a unity (1.0). A, Responses to concentration series of NaCl with and without 0.5 mol/L Glc before and after lingual treatment of Phl. Responses to 1–100 mmol/L NaCl were shown as open circles (before Phl) or open triangles (after Phl) with black dotted line. B, Whole-nerve responses to concentration series of Glc with or without 10 mmol/L NaCl before and after lingual treatment of Phl. C, Dose-dependent effect of Phl on CT nerve response to 0.5 mol/L Glc + 10 mmol/L NaCl. Values indicated are means ± SE. Results of repeated measures ANOVA are shown in Table 1. Results of post hoc Fisher test to evaluate enhancement of the response by Glc and NaCl mixture was shown by top symbols, and that to evaluate suppression by Phl was shown by other symbols; *P < .05, ^†P < .01. CT, chorda tympani; WT, wild-type
