The effect of angiotensin II and indomethacin on uterine artery blood flow in pregnant monkeys. 1977

L Speroff, and R V Haning, and R M Levin

In experiments performed in anesthetized monkeys in the third trimester of pregnancy, mean maternal arterial blood pressure was continuously monitored, the uterine artery blood flow was measured with an electromagnetic flow probe, and prostaglandin levels were assayed in the uterine venous effluent. After inhibition of prostaglandin systhesis with indomethacin, the mean arterial blood pressure in response to angiotensin II was greater than the response prior to indomethacin treatment, and an increase in uterine artery blood flow was prevented. These findings are consistent with the suggestion that prostaglandins mediate the uterine artery blood flow response to angiotensin II, as well as modifying the maternal systemic blood pressure response.

D007213 Indomethacin A non-steroidal anti-inflammatory agent (NSAID) that inhibits CYCLOOXYGENASE, which is necessary for the formation of PROSTAGLANDINS and other AUTACOIDS.

D009609 Nitrous Oxide Nitrogen oxide (N2O). A colorless, odorless gas that is used as an anesthetic and analgesic. High concentrations cause a narcotic effect and may replace oxygen, causing death by asphyxia. It is also used as a food aerosol in the preparation of whipping cream. Laughing Gas,Nitrogen Protoxide,Gas, Laughing,Oxide, Nitrous
D011247 Pregnancy The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH. Gestation,Pregnancies
D011458 Prostaglandins E (11 alpha,13E,15S)-11,15-Dihydroxy-9-oxoprost-13-en-1-oic acid (PGE(1)); (5Z,11 alpha,13E,15S)-11,15-dihydroxy-9-oxoprosta-5,13-dien-1-oic acid (PGE(2)); and (5Z,11 alpha,13E,15S,17Z)-11,15-dihydroxy-9-oxoprosta-5,13,17-trien-1-oic acid (PGE(3)). Three of the six naturally occurring prostaglandins. They are considered primary in that no one is derived from another in living organisms. Originally isolated from sheep seminal fluid and vesicles, they are found in many organs and tissues and play a major role in mediating various physiological activities. PGE
D011460 Prostaglandins F (9 alpha,11 alpha,13E,15S)-9,11,15-Trihydroxyprost-13-en-1-oic acid (PGF(1 alpha)); (5Z,9 alpha,11,alpha,13E,15S)-9,11,15-trihydroxyprosta-5,13-dien-1-oic acid (PGF(2 alpha)); (5Z,9 alpha,11 alpha,13E,15S,17Z)-9,11,15-trihydroxyprosta-5,13,17-trien-1-oic acid (PGF(3 alpha)). A family of prostaglandins that includes three of the six naturally occurring prostaglandins. All naturally occurring PGF have an alpha configuration at the 9-carbon position. They stimulate uterine and bronchial smooth muscle and are often used as oxytocics. PGF

D003472 Curare Plant extracts from several species, including genera STRYCHNOS and Chondodendron, which contain TETRAHYDROISOQUINOLINES that produce PARALYSIS of skeletal muscle. These extracts are toxic and must be used with the administration of artificial respiration.
