Effects of prostacyclin on contractile properties of isolated mammalian cardiac muscle.

abstract：:Gangliosides, sialic acid-containing glycosphigolipids, are localized mostly to the outer leaflet of the lipid bilayer in the plasma membrane, particularly in brain. Gangliosides reduce edema formation, restore glucose metabolism, and increase cerebral blood flow after focal ischemia in the rat brain. We wished to det...
