Table 1.

Showing the median (range) of the ratio (%) between ATF3 labeled and total number of MN and dorsal rot ganglia neurons after different types of nerve lesions.

Survival times	Moto-neurons. Ventral root avulsion	Dorsal root ganglia. Dorsal root avulsion	Moto-neurons. Sciatic nerve transection	Dorsal root ganglia. Sciatic nerve transection
1.5 h	0.0	1.3 (0–2.5)	0.0	0.0
3 h	33.5 (24.5–42.0)	1.0 (0–1.6)	0.0	0.0
6 h	100	1.4 (1.3–19)	0,0	1.3(0.9–1.5)
24 h	100	19.0 (11.0–23.8)	59.5(50.0–69.9)	55.4(48.2-59.5)
3 days	100	4.2 (4.0–6.1)	57.4(49.2-80.0)	60.2(45.5–63.8)
7 days	100	0.0(0–1.2)	50.0(47.5–68.9)	52.1(42.1–60.5)
21 days	(100)	0.6(0–1.0)	37.5(30.8–60.0)	45.6(42.6–59.3)

Value (100) means that although all remaining neurons at 21 days are labeled, cell death was immense (66.5%). No significant cell death was at hand at other survival times.
