A study was conducted to compare catecholamine concentrations in nervous tissues of stress-susceptible (SS) and stress-resistant (SR) pigs that were physically stressed. Ten pigs were included in each group on the basis of results of halothane screening tests, blood typing analysis, and examination for serum creatine kinase (CK) activities at 6 weeks of(More)
Eight stress-susceptible and eight normal pigs were used in the first portion of the study. Urine samples were collected for 24 hr over 4 consecutive days while the pigs were kept in metabolism cages. Each 24-hr sample was assayed for epinephrine, norepinephrine and dopamine. Urinary levels of dopamine were lower (P < .01) in the stress-susceptible pigs. No(More)
The antidiabetic agent troglitazone was given to groups of 4 cynomolgus monkeys per sex at 300, 600, or 1200 mg/kg daily by gavage for 52 weeks. A group of 4 monkeys per sex received vehicle alone and served as controls. Emesis and soft stool or diarrhea occurred sporadically in all troglitazone-treated groups, but did not compromise animal health. There(More)
We investigated whether lack of the canalicular multispecific organic anion transporter in transport-deficient (TR-) rats would result in plasma and urinary accumulation of troglitazone or its major metabolites and whether any accumulation would be associated with increased levels of bilirubin or bile acids. Administration of a single oral dose of(More)
BACKGROUND Since 1990, there has been significant research devoted toward development of a noninvasive physiological glucose sensor. In this article, we report on the use of optical polarimetry for the noninvasive measurement of physiological glucose concentration in the anterior chamber of the eye of New Zealand white (NZW) rabbits. METHOD Measurements(More)
Gastric acid secretion was measured in male and female cynomolgus monkeys under basal conditions and in response to intravenous administration of pentagastrin (PG). There were no statistically significant differences between males and females in either basal or PG-stimulated gastric acid output. Neither were differences between males and females(More)
Ambulatory ECG, approximately 18 to 24 hours in duration, were obtained from 113 male and 115 female clinically normal, purpose-bred Beagles. The ECG analyzed semi-automatically (44 males, 46 females) were evaluated for heart rate, ventricular ectopic complexes (VEC), bradycardia, and sinus pause; those analyzed by visual inspection (69 males, 69 females)(More)

Hepatocellular vacuolation can be a diagnostic challenge since cytoplasmic accumulations of various substances (lipid, water, phospholipids, glycogen, and plasma) can have a similar morphology. Cytoplasmic accumulation of phospholipids following administration of cationic amphiphilic drugs (CAD) can be particularly difficult to differentiate from(More)
