摘要
Intrastriatal injections of kainic acid in rat brain, which destroyed striatal nerve cell bodies and their axons projecting to the substantia nigra (s. nigra) decreased the rate of breakdown of exogenously added substance P by washed slice preparation of s. nigra. Injection of 6-hydroxydopamine (6-OHDA) into the s. nigra, which destroys the dopamine nerve cell bodies in this region, did not significantly affect the rate of degradation of substance P by nigral slices. Part of the peptidase activity responsible for breakdown of substance P in the s. nigra may thus be located on the terminals of striatal afferents to the s. nigra. © 1979.
