-
aAnimals (8 months old) were used to measure T-type current and excitability parameters
-
bAnimals (8 months old) were used to measure Na+ current
-
cAnimals were used to measure T-type current
-
dANOVA one way test, p < 0.01
-
eThere was no significant difference between the group of diabetic hypoalgesic or hyperalgesic and control rats (p > 0.08, ANOVA one way test)
-
fStudent’s t-test: p < 0.001 for each control and corresponding diabetic group
-
gStudent’s t-test with α level adjusted with Bonferroni’s procedure: p < 0.005 when diabetic hypoalgesic and hyperalgesic groups were compared with the same control group
