Anorexigenic effects of naltrexone in rats
… consumption. Previous studies indicate that rats cannot discriminate NTX from saline, except at very high doses. However, in those discrimination experiments, NTX-treated animals had not been fed palatable foods, i.e., diets whose consumption affects the endogenous opioid system thereby …

Invertebrate glycoprotein-induced inflammation in rats
The present program of research, therefore, was designed to attempt to gain new insights into the possible etiology of inflammatory states - for when new information concerning the etiology of these diseases states becomes available, more meaningful screening procedures for anti-inflammatory drugs …

Effects of Environmental Temperature on Sleep and Waking in Normal Rats and Rats With Basal Forebrain Damage
… of rapid-eye-movement (REM) sleep in normal rats vary within the thermoneutral zone defined by minimal metabolic rate--25 to 31(DEGREES)C--peaking toward the upper end of this zone (Szymusiak and Satinoff, Physiol. Behav. 26:687, 1981). Given the sensitivity of normal sleep to small changes …

Amiodarone-induced pulmonary toxicity in F344 rats
… A protocol was developed in which male F344 rats were instilled intratracheally (i.t.) with AD (6.25 mg/kg with a 3.125 mg/ml solution) in sterile water or the sterile water vehicle on days 0 and 2, a protocol that led to the development of pulmonary fibrosis on day 28 in the AD-treated …

The Reversibility of Differential Rearing in Rats
<p>Two groups of rats were raised in two different environments for 75 days beginning at 25 days of age. One group was raised in an enriched condition (EC), and one group in an impoverished condition (IC). At 91 days of age, all rats were tested on a spatial reversal learning task to determine if …

Studies in the Folate Metabolism of Rats
… was studied in three-week-old weanling Wistar rats. Distribution of radioactivity after an oral dose of 2-14C folic acid was determined in urine, faeces, liver, and gut of the animals. Some of the urinary metabolites were characterized by column chromatography. The effects of an oral dose of …

Exercise induced neuroprotection in spontaneuosly running rats
… after unilateral lesions with 6-hydroxydopamine. Rats were divided into runners (had access to running wheel) and non-runners (their running wheels were immobilised). Two weeks after injection of the neurotoxin, the rats were injected with apomorphine and the number of ipsilateral and …

HIF, HAPE, and Hilltop rats: a paradox unfolding
Hilltop rats develop a pathological syndrome resembling chronic mountain sickness (CMS) in humans. Manifestations of CMS include polycythemia, pulmonary vascular remodeling, pulmonary hypertension and right ventricular hypertrophy. Paradoxically, Hilltop rats are more resistant to acute hypoxic …

Effect of rutaecarpine on caffeine pharmacokinetics in rats
… in order for it to work. Therefore, we tested in rats the effect of single dose after 3, 6, 12, 24 hour and 7 doses (once a day, for seven days) of oral 100 mg/kg rutaecarpine (in suspension) induction on caffeine pharmacokinetics upon 15 mg/kg intravenous bolus and 20 mg/kg oral caffeine doses. …

DIETARY OBESITY, EXERCISE TRAINING, AND THERMOGENESIS IN RATS
… in thermogenesis to the energy balance of either rats or humans is not known. There is some evidence that differences in post-prandial heat production (dietary-induced thermogenesis), can explain why some individuals gain weight easily when overeating and others do not. There is also evidence that …
