Health care providers' knowledge about contraceptive evidence: a barrier to quality family planning care?
The lack of consistent and accurate knowledge about contraception among providers has the potential to dramatically affect providers' ability to provide quality contraceptive care for their patients, which could have an impact on their ability to prevent unintended pregnancies.
The sensitivity of guinea pig uterine artery but not carotid artery to thromboxane is reduced during pregnancy. Although the precise mechanism remains unclear, both endothelium-derived relaxing factor and an indomethacin-sensitive contracting factor are involved. If indomethacin-sensitive contracting factor is released by humans and disease alters that release, it is possible that any enhanced contractile response to thromboxane resulting from the loss of endothelium-derived relaxing agents such as prostacyclin and endothelium-derived relaxing factor would be offset by the loss of indomethacin-sensitive contracting factor.
