Despite the evidence for a functional role of nitric oxide (NO) in the regulation of uterine contractility in several species, there is little information about the effects of this gas on the mouse uterus. The aims of this study were to investigate if the NO relaxation pathway is present in mouse pregnant uterus and the relationship with the uterotonic prostaglandins (PGs E and F 2α )...
Accumulated evidence suggests that platelet-activating factor (PAF) may have a role in implantation by stimulating prostaglandin (PG) production. Since we had demonstrated that nitric oxide (NO) can increase uterine PGs, the aim of this study was to explore whether or not NO could mediate rat uterus responses to PAF on day 5 of gestation, when implantation takes place. Uterine motility was enhanced...
