[Roles of prostaglandin on rabbit vesicourethral smooth muscle contraction].
The effects of prostaglandin (PG) E1, E2 and F2 alpha on isolated smooth muscles of rabbit bladder and urethra were studied by in vitro techniques for recording contractile activities. To examine the mechanism of PGs' effect, intracellular cyclic AMP content was also measured by radioimmunoassay. Spontaneous contractile force of muscle strips isolated from rabbit urinary bladder dome and base w...

متن کاملStudies on the nature of a prostaglandin receptor in canine and rabbit vascular smooth muscle.
The contractile response of rabbit renal arteries and canine tibial arteries to prostaglandins A2, B2, F2alpha, E1, E2, D2, and B1 was associated with a reduction in total sulfhydryl group content of smooth muscle. The total sulfhydryl content of rabbit renal and canine tibial arteries and was not affected by norepinephrine or potassium chloride. Reduction of disulfide groups with dithiothreito...
متن کاملEffects of prostaglandin F2alpha on membrane currents in rabbit middle cerebral arterial smooth muscle cells.
Although PGF(2alpha) affects contractility of vascular smooth muscles, no studies to date have addressed the electrophysiological mechanism of this effect. The purpose of our investigation was to examine the direct effects of PGF(2alpha) on membrane potentials, Ca(2+)-activated K(+) (K(Ca)) channels, delayed rectifier K(+) (K(V)) channels, and L-type Ca(2+) channels with the patch-clamp techniq...
