Forty dogs underwent anterior descending coronary artery dissection with most having occlusion that was either maintained or reperfused. Study was performed 1-4 days later. Multiple electrodes placed in normal and ischemic zones were used to determine the depth of the epicardial rim overlying a
The effect of intravenous physostigmine on cerebral perfusion of patients with cortical stroke was investigated using hexamethyl-propyleneamine oxime (HMPAO) single-photon emission computed tomography. Each patient was studied twice, afteran intravenous infusion of either 1 mg of physostigmine
Heart failure is associated with attenuation of parasympathetic nervous function and enhanced renin-angiotensin activity. We tested whether there was a dysfunction in the efferent cholinergic neurotransmission in the heart of rats with chronic myocardial infarction (MI) and the potential role of
An auditory discrimination paradigm was employed to elicit event-related brain potentials in 13 patients with Alzheimer's disease and 14 patients with multi-infarct dementia. The P300 latency was significantly prolonged in 12 patients with dementia compared with age-matched controls and showed a
This study examined the onset, time course of development and response to overdrive stimulation of ventricular tachycardia in 10 dogs that underwent a Harris two-stage ligation of the left anterior descending coronary artery. Transient (12 +/- 3 minutes) complete atrioventricular (AV) block was
Our recent studies have shown that, as indicated by vagal stimulation, an acetylcholinesterase inhibitor donepezil, an anti-Alzheimer's disease drug, prevents progression of heart failure in rats with myocardial infarction, and activates a common cell survival signal shared by acetylcholine (ACh) in
A multi-dimensional column chromatographic method employing UV spectrometric detection was optimised and successfully used in a comparative bio-availability study of aspirin obtained from different commercially available oral dosage forms. Sample clean-up was achieved by on-line solid-phase
This report presents a case of central anticholinergic syndrome after general anesthesia in a patient with severe coronary heart disease. Eight years ago he had had two myocardial infarctions; after undergoing a bypass operation he suffered a third one. His angina pectoris had increased over the
The prevalence of severe dementia in the United States is about 1.3 million cases, of which at least 50 to 60% are of the Alzheimer type. Severe dementia of the Alzheimer type is found rarely in a clearly dominant pattern, although often one or more relatives are affected. Down's syndrome in adults
