PURPOSE Antineoplastic drugs belonging to platinum or taxane families are severely neurotoxic, inducing the onset of disabling peripheral neuropathies with different clinical signs. Acetyl-L-carnitine (ALC) is a natural occurring compound with a neuroprotective activity in several experimental paradigms. In this study we have tested the hypothesis that ALC(More)
The present study was designed to characterize cardiac autonomic neuropathy in streptozotocin-induced (45 mg/kg i.v.) diabetic rat by analysis of heart rate variability (HRV), and to assess, in this model, the effects of treatment with acetyl-L-carnitine (ALC). Heart rate was reduced in diabetic rats (332+/-22 vs. 411+/-35 beat per min; P<0.0001). This(More)
There is strong evidence that autonomic imbalance plays an important role in progression of heart failure. Analysis of heart rate variability (HRV) has achieved substantial acceptance as a noninvasive method for the assessment of autonomic tone. The purpose of this investigation was to study HRV in an experimental model of heart failure using(More)
The prototypical dopamine and serotonin antagonist (+/-)-7-chloro-9-(4-methylpiperazin-1-yl)-9,10-dihydropyrrolo[2,1-b][1,3]benzothiazepine (5) was resolved into its R and S enantiomers via crystallization of the diastereomeric tartaric acid salts. Binding studies confirmed that the (R)-(-)-enantiomer is a more potent D(2) receptor antagonist than the(More)
Aging is associated with a reduction in the maximum density of n-methyl-d-aspartate (NMDA)-sensitive glutamate binding sites in the hippocampus of Fischer 344 rats. This study was designed to investigate the effect of acetyl-l-carnitine (ALCAR) on NMDA receptors in the old rat (24 months) after chronic or single-dose treatments. The number of NMDA receptors(More)
BACKGROUND Several animal models of cerebral ischemia have been developed to investigate both pathophysiology and pharmacological treatment. The aim of this study was to verify the prognostic value of EEG power spectra analysis in a two-vessel plus hypotension rat model of transient global ischemia. METHODS Spontaneously hypertensive rats (SHRs) and(More)
To evaluate the effects of hypertension on cardiac hypertrophy, on myocardial structure, and on ventricular arrhythmias, 27 3-month-old spontaneously hypertensive rats were treated with enalapril (10 mg/kg) daily for 11 months and compared with 26 untreated control rats. Systolic arterial pressure was significantly decreased in treated rats, and at the end(More)
Transection of the fimbria-fornix in adult rats is a useful model for producing impairments of cholinergic activity in the hippocampus (HIPP) and atrophy of the medial septum cholinergic perikarya, similar to those observed during senescence, that are possibly due to the lack of nerve growth factor (NGF) retrogradely transported from the hippocampus. In our(More)
Transection of the fimbria-fornix bundle in adult rats results in degeneration of the septohippocampal cholinergic pathway, reminiscent of that occurring in aging as well as Alzheimer disease. We report here a study of the effect of a treatment with acetyl-L-carnitine (ALCAR) in three-month-old Fischer 344 rats bearing a partial unilateral fimbria-fornix(More)
Acute i.p. administration of Acetyl-L-Carnitine (ALCAR), a component of several biological systems, has been found to modify spontaneous and evoked electrocortical activity in young rats, and, in the old rats, to improve learning ability and to increase the number of NMDA receptors in the whole brain. The present study was aimed at ascertaining the effect(More)
