The effect of intraperitoneal NGF (IP NGF) or intrathecal NGF on the percentage of DRG cells expressing BDNF mRNA, BDNF immunoreactivity, or trkA immunoreactivity

	Control	IP NGF	Intrathecal NGF
BDNF immunoreactivity	22.3  ± 1.2% (3)	22.3  ± 3.3% (3)	40  ± 1.5% (4)1-160
BDNF mRNA	28.5  ± 3.3% (4)	43.7  ± 4.4% (3)*	37.8  ± 1.4% (4)*
TrkA immunoreactivity	37.8  ± 2.2% (4)	37.5  ± 2.0% (4)	42.3  ± 3.1% (3)

The figures in brackets indicate the number of animals analyzed.

^* indicates significantly different from controls at p< 0.05;

F1-160:  indicates p < 0.001.
