... examined using ovariectomized, estrogen (E)-treated guinea pigs. Following 3 days of E treatment, both UBF and UBV measurements were found to be elevated and associated with a causally-related increase in intraluminal uterine oxygen availability levels. Following the acute clamping of the uterine arteries...

... and some have failed to show an effect with that dose. We determined the pharmacokinetics of furosemide administered directly to the airway in 7 young adult male guinea pigs who received intravenous and intratracheal doses of furosemide. Each animal received a 3 mg/kg i.v. bolus, 1, 3 and 6 mg/kg i.t. in 2...

...M.P. Morin-Surun; E. Boudinot; T. Schäfer; M. Denavit-Saubié Central brain stem chemosensitivity plays an essential role in acid-base regulation. The site of the chemosensitive neuronal elements has not yet been clearly established. To address this question, we used an in vitro adult guinea pig...

...Lawrence T. Weaver; Lisa Landymore-Lim; Alan Lucas The effects of natural suckling versus a cow’s milk formula on gastrointestinal growth and mucosal function were measured in newborn guinea pigs during the first 8 days of postnatal life. Comparable growth was achieved between the two groups. Both...

...David R. Garris The relationships between regional uterine blood flow (UBF), placental blood volume (maternal compartment) and fetal-placental weights and size were determined at specific gestational stages in the guinea pig. Regional variations in UBF were noted between days 27 and 65 of pregnancy...

...D. Durand; M. Dalle; J.-P. Barlet In pregnant guinea pigs on day 60 of gestation, maternal hypercalcemia induced by calcium infusion (10 mg Ca/kg body weight/h, during 2 h) had no significant effect on the fetal plasma calcium level. By contrast, on day 66 of gestation the same infusion of calcium...
