Figure 1From: Effect of electro-acupuncture on ovarian expression of α (1)- and β (2)-adrenoceptors, and p75 neurotrophin receptors in rats with steroid-induced polycystic ovariesSchematic drawing of the placement and stimulation of the acupuncture needles. Two needles were placed bilaterally in m. erector spinae at the level of Th12 and two were placed in m. quadriceps bilaterally. The needles were then attached to an electrical stimulator for electro-acupuncture (EA) treatment. Reprinted with permission from Biol Reprod (2000) 63:1507-1513.Back to article page
