Effects of Endokinin A/B and Endokinin C/D on the modulation of pain in mice.

abstract：:Heat-stable enterotoxin b (STb) of Escherichia coli is a 48-amino acid basic, disulfide-bonded peptide that causes intestinal secretion in experimental animal models. Recent evidence suggests that the in vivo mechanism of STb action involves release of 5-hydroxytryptamine (5-HT) and production of prostaglandin E2 (PGE...
