Inducing analgesia by implantation of cells releasing neuroactive substances
First Claim
1. A method of inducing analgesia or reducing pain comprising implanting isolated, substantially homogeneously purified chromaffin cells or adrenal medullary tissue in nociceptor region of central nervous system of a host susceptible to pain, and stimulating said cells or tissue by infecting a nicotinic or muscarinic agonist to release effective amount of analgesic substance to reduce pain.

Abstract
A method of inducing analgesia or reducing pain is described. The method involves implanting in the central nervous system of a host susceptible to pain, living material capable of releasing effective amount of analgesic substance when interacted with a stimulus which induces said material to release analgesic amount of said substance. The procedure described herein reduces sensitivity to intractable pain.
