Substance-P pathways in rat brain.
The characterization and subsequent availability of synthetic substance P has renewed interest in the role of this undecapeptide in central-nervous-system function (Mroz & Leeman, 1974). Biochemical and electrophysiological studies have demonstrated that substance P may function as an excitatory transmitter in primary sensory neurons terminating in the spinal cord (Otsuka & Konishi, 1975). In t...
متن کاملOntogeny of substance P receptor binding sites in rat brain.
The ontogeny of substance P (SP) receptor binding sites in rat brain has been studied using both membrane binding assays and in vitro receptor autoradiography. The density of SP binding sites is maximal 1 d before birth and decreases thereafter to reach adult values 14 d after birth. During the early postnatal period, the distribution of SP binding sites undergoes major modifications. For examp...
متن کاملThe degradation of acidsoluble collagen by rat-liver preparations.
nucleotide was increased, and, assuming that the product was derived from oligonucleotides and deoxyribonucleoside triphosphates, the synthesis amounted to 74% of the deoxyribonucleic acid primer. 4. The nucleotidyltransferase was inhibited and the lag phase extended by 3'-phosphoryl-terminal oligonucleotides from a splenic-deoxyribonuclease digest of deoxyribonucleic acid. 5. The compounds obt...
متن کاملInhibition of carrageenan induced inflammation in the rat knee joint by substance P antagonist.
The pathophysiology of acute joint inflammation remains unclear. Evidence is available to suggest a neurally mediated component to the inflammatory process. Acute joint inflammation in the rat knee, induced by intra-articular injection of 2% carrageenan, was reduced by 44% in animals whose knee had previously been injected with 1% capsaicin, while chronic joint denervation produced a 37% reduct...
متن کاملInteraction between substance P and gastrin-releasing peptide on thyrotropin secretion by rat pituitary in vitro.
The effect of substance P (SP) on thyrotropin (TSH) secretion is controversial. In this study we evaluated the effect of SP on TSH secretion by hemipituitaries of 3-month-old Wistar rats in vitro and its interaction with gastrin-releasing peptide (GRP) at equimolar concentrations (1 microM and 10 microM). TSH release was measured under basal conditions and 30 min after incubation in the absence...
