Morphological analysis of sciatic nerves between iPLA₂β^+/+ and iPLA₂β^−/− mice

	Density of myelinated fibers (per mm2)	Total area of nerve fascicles (mm2)	Number of myelinated fibers (density × area)
+/+ (n = 4)	20156 ± 4007	0.189 ± 0.037	3735 ± 554
−/− (n = 7)	22922 ± 1695	0.136 ± 0.117	3115 ± 234
		(p < 0.05)	(p < 0.05)

The number of myelinated fibers per unit area was counted in sciatic nerves. Mice aged 95–103 weeks old were examined. p values were calculated using the Student's t test.
