Nerve Growth Factor (NGF) protein concentrations and NGF mRNA expression (mean ± SEM) in the ovaries, the adrenal glands and the dorsal part of the spinal cord in the four experimental groups the healthy control group, the healthy group receiving electro-acupuncture (EA), the polycystic ovary (PCO) control group, and the PCO group receiving EA.

Spinal cord	867.36 ± 65.52	1600.59 ± 360.03	1351.26 ± 220.82	1081.94 ± 193.72

	NGF mRNA expression (O.D. 450/690)

Ovary	1.02 ± 0.19	1.10 ± 0.2	0.35 ± 0.06^c	0.45 ± 0.15
Adrenal gland	0.41 ± 0.06	0.51 ± 0.07	0.32 ± 0.06	0.37 ± 0.05

^ap < 0.001 when the PCO control group were compared with the healthy control group and healthy group receiving EA. ^bp < 0.05 when the PCO group receiving EA were compared with the PCO control group. ^cp < 0.001 when the PCO control group were compared with the healthy control group and the healthy group receiving EA.
