KATP channel subunits in rat dorsal root ganglia: alterations by painful axotomy

Molecular Pain

Table 1 Areas of Schmidt-Lanterman Incisures in peripheral nerves diminish after painful axotomy.

	Area of Schmidt-Lanterman Incisures (μm²)
	Dorsal root	DRG	Peripheral nerve
Control L5	2.7 ± 0.7 (n = 46)	5.3 ± 3.9^f(n = 116)	2.3 ± 1.0 (n = 111)
SNL L5	1.6 ± 0.9* (n = 142)	2.9 ± 2.3*,^f(n = 117)	0.5 ± 0.3* (n = 116)

Areas of Schmidt-Lanterman Incisures measured in electron microscopy sections obtained from three different sites proximal to axotomy, in comparison with similar sites in control DRG neurons. Sampling sites were the dorsal root proximal to DRG, the DRG, and the peripheral nerve distal to DRG but proximal to axotomy. *: p < 0.01 vs control L5 (by Student's t tests). ^f:p < 0.01 vs dorsal root and peripheral nerve (by Bonferroni post hoc tests).
