title: [Dynamics of biliary prostaglandin secretion in patients with dyskinesia of the biliary tracts].
abstract: The time course of biliary secretion of prostaglandins (PG)E1 and F2 alpha was studied in 20 patients with primary dysfunctions in the cholepoietic system. The studies indicated that baseline high PGE1 levels and slow increases in PGF2 alpha during vesical reflex might be one of the factors predisposing to biliary hypokinesia. In patients with Oddi's sphincter spasms, the period of active PGE1 synthesis coincides with that of sphincter spasm. It is suggest that the latter is due to PGE1-induced muscle spasm of the duodenum whose fibers are an integral part of the intricate muscle system of Oddi's sphincter. In Oddi's sphincter spasm concurrent with biliary dyskinesia, the curve of PGF2 alpha virtually little differs from that in Oddi's sphincter spasm alone. PGE1 increases at the closed sphincter stage in the same way as that elevates in isolated sphincter spasm, but in patients with biliary hypokinesia contaminant with Oddi's sphincter spasm PGE1 shows its concentration in the vesical reflex phase, which appears to result in biliary hypokinesia. PGE1 and PGF2 alpha imbalance is one of the links in the pathogenesis of biliary dyskinesia.
