The neuroleptic haloperidol was found to produce increased defecation in laboratory rats when tested in well habituated environments. It is well known that haloperidol induces catalepsy through antagonism of striatal dopaminergic receptor mechanisms. When another cataleptic agent, morphine, was tested, no significant increases in defectation were detected.(More)
Most investigators have found a decrease in emotional defecation in rats given neuroleptics in novel environments, supporting their action as a major tranquilizer. We have found, however, that in rats a profound increase in emotional defecation can result from neuroleptic administration in well habituated environments, such as the homecage.

AIM To identify which factors influence the final visual acuity in children with anisometropic amblyopia. METHODS A retrospective analysis of 112 children with anisometropic amblyopia, identified from examining all case notes of children who had failed preschool or school screening. RESULTS The age at presentation had no effect on the final visual(More)
The increased locomotor activity induced by systemic injections of d-amphetamine or scopolamine in rats was studied in Digiscan Animal Activity Monitors. This multifactorial analysis of locomotion demonstrated that activity measures of horizontal (ambulatory), vertical (rearing), stereotypic, and rotational behaviors differed depending on dose and drug. The(More)
Recently, Bauer reported that amphetamine did not increase rearing behavior in adult rats. This result is at variance with many earlier reports demonstrating that amphetamine does increase rearing behavior. Because Bauer's automated measure only detected rearing when it occurred on the wall of the cage, it is possible that amphetamine only increased rearing(More)
Evidence from a variety of studies suggests that many mammalian muscles are partitioned with respect to their architecture and innervation. Each of these specific muscle subvolumes is innervated by an individual muscle nerve branch, contains motor unit territories with a unique array of physiological attributes and has been known as a neuromuscular(More)
The cat (Felis silvestris catus) has a higher dietary protein requirement than omnivores and herbivores, thought to be due to metabolic inflexibility. An aspect of metabolic flexibility was examined with studies of whole-body protein turnover at two levels of dietary protein energy, moderate protein (MP; 20 %) and high protein (HP; 70 %), in five adult cats(More)
The effect of two levels of dietary protein energy, moderate (20%; MP) and high (70%; HP), on urea kinetics in eleven domestic cats was studied. After a 3-week prefeed, a single dose of [(15)N(15)N]urea was administered, and urine and faeces collected over the subsequent 5 d. For each 24 h period, total urea and enrichment of [(15)N(15)N]- and(More)
