Folate Metabolism in the Guinea Pig
… of [2-14c]and [3',5',7,9-2H folic acid to normal guinea pigs, p-acetamidobenzoate (major product) and p-acetamidobenzoyl- L-glutamate (minor product) were found in the urine. No radioactive folate was excreted except at very high doses when trace amounts of folic acid appeared, or after …

Blood Reservoir Function of the Fetal Guinea Pig Liver
… hemorrhage and volume loading. Nineteen pregnant guinea pig sows and 54 near-term fetuses were injected intravenously with <sup>51</sup>Cr-labeled red cells while the fetuses remained in utero. Ninety seconds later a 0.5-1.0 g sample of liver was garroted with a sharp wire into a tared tube with …

A guinea pig model of human respiratory syncytial virus lung infection
… of the airway inflammation underlying asthma, a guinea pig model of human RSV lung infection was developed to test the hypothesis that RSV persists within the lung following resolution of acute bronchiolitis. One month old, "juvenile" guinea pigs, intranasally inoculated with human RSV, were …

Cellular Calcium Movements and Excitation-Contraction Coupling in Guinea Pig Atria
Guinea pig left atria were suspended in a tissue bath of normal Krebs-Henseleit solution which was aerated with 95% O$\sb2$/5% CO$\sb2$ and maintained at 27$\sp\circ$C. The atria were attached to a force transducer and impaled with calcium sensitive micro-electrodes. The tissue was stimulated …

The Temporal Nature of Ectopic Activity in Guinea Pig Ventricular Myocardium
The temporal nature of ectopic activity is important to elucidating the mechanisms that can lead to arrhythmogenesis. However, challenges remain in distinguishing between ectopic and non-ectopic beats. A new methodology was developed and validated to distinguish between beat types. Rapid pacing was …

The transfer of antibody from mother to foetus in the guinea-pig
… birth, after birth, or both. In man, rabbit and guinea-pig, for example, the transfer of immunity from mother to young occurs entirely prenatally. In the ungulate, horse and pig the passive transfer of immunity occurs postnatally, whilst in dog, rat and mouse it occurs both pre- and postnatally. …

Adeno-Associated Mediated Transduction of Sensory Epithelia Within the Guinea Pig Cochlea
… transduction of sensory epithelia within the guinea pig cochlea Chairperson: Dr. David J. Poulsen, PhD. Hearing loss is the most common disability of the senses and affects 250 million people worldwide. This condition is often caused by the degeneration of the sensory cells, called hair cells, …

Endogenous cardioactive substances in blood: effects on the isolated guinea-pig atria
… contractility. Isolated left and right guinea-pig au -ia were used as bioassay for the detection of endogenous cardiotonic substances in bovine serum. Results show that serum that had been buffer exchanged to Krebs-Henseleit by dialysis or Sephadex G-25, produced positive inotropic and …

Primary neuronal degeneration in the guinea pig effects on spontaneous rate-type
… by recording from single cochlear neurons in guinea pigs and evaluating neuronal degeneration via confocal microscopy 14 days after exposure to noise (4-8kHz, 106dB SPL, 2 hrs). Suprathreshold amplitudes of otoacoustic emissions recovered post-exposure, suggesting complete hair cell recovery; …

Chronic prenatal ethanol exposure produces neurobehavioural and metabolic dysfunction in guinea pig offspring
… of this thesis research was to study, in the guinea pig, neurobehavioural and metabolic effects of CPEE and to investigate whether these effects were associated with altered CNS and peripheral insulin/IGF signaling pathways. In postnatal offspring, CPEE decreased brain weight and altered …

Moderate Ethanol Consumption by the Pregnant Guinea Pig Increases Ethanol Preference in Offspring
… frontal cortex. Pregnant Dunkin-Hartley-strain guinea pigs were given 24-h access to aqueous ethanol solution (5%, v/v) sweetened with sucralose (1g/L) or aqueous sucralose solution (1g/L) throughout gestation. Spontaneous locomotor activity in an open field was measured in offspring on …

The Mechanism of the Action of Gastrin on Guinea Pig Ileum Smooth Muscle
… of acetylcholine from Auerbach's plexus of guinea pig terminal ileum which, in turn, caused the muscle to contract. The purpose of this study was to verify the findings of Vizi et al. and to describe the mechanism and sites at which this action of gastrin was mediated.
