Effects of inflammatory pH conditions on calcium signals in rat sensory
neurons. Fura-2 imaging experiments with rat sensory neurons treated
with (a) short (60s) and (b) long (20 min) application of extracellular
pH 7.4 (black trace, N=356 neurons), pH 7 (red trace, N=302 neurons), pH
6.5 (green trace, N=383 neurons) and pH 6 (blue trace, N=386 neurons).
Twelve recordings for each pH from 4 rats (1 rat per pH) are shown. The
right bar graphs represent delta ratio 340/380 for different pH values.
P > 0.05; One-way ANOVA on ranks. Traces represent means ±
SEM.
