abstract：:A two-site radio-immunoassay for beta NGF demonstrated 5-10 pg of NGF in the normal, adult rat iris. Ciliarectomy or sympathectomy did not significantly alter the amount of NGF after 10 days. However, denervation including all sensory axons (stereotactic lesion distal to the trigeminal ganglion) increased the level to...
