Chagas' disease is common in Latin America and is caused by Trypanosoma cruzi. It is usually associated with chronic cardiomyopathy, the progression of which could be related to genetic factors. As alterations in the renin-angiotensin-aldosterone system have been reported in the disease, the aim of this study was to determine whether associated genetic(More)
The herbicide paraquat is associated with a high mortality rate. It produces multiorgan damage through the induction of acute oxidative stress, by generation of reactive oxygen species that cause oxidative damage to biomolecules. In addition to general supportive measures, the management of paraquat poisoning includes gastric washing, forced diuresis,(More)
We report a 3-y-o boy who accidentally poisoned himself with valproic acid (VPA). Clinical features included profound coma, depressed respiration and miosis. Treatment included naloxone, gastric lavage, and activated charcoal and a saline cathartic. The patient fully recovered and was discharged 24 h after the admission. Prompt use of naloxone is advised(More)
Transition metals have been described as regulators of receptor's function. here, we studied the effects of chronic administration of Cu2+ or the Cu2+ chelator penicillamine (PA) on the functional and binding properties of the muscarinic receptors (MR) on selected areas of rat's brain. Groups of 10 Sprague-Dawley rats were treated daily, for 45 days with(More)
OBJECTIVE To investigate the possible role of muscarinic cholinergic receptors (MCRs) in the depression of myocardial function induced by propofol, an intravenous anesthetic chemically unrelated to other drugs. Although adverse effects are rare, bradycardia has been reported and this can lead to cardiac arrest in some patients. The mechanism behind this(More)
Since paraquat poisoning causes multiorgan damage through the generation of several redox products, the usual therapy includes antioxidative drugs, such as N-acetylcysteine. We investigated whether selected antioxidative drugs can improve survival from acute paraquat toxicity. Forty-eight male 2-3-mo-old Wistar rats were divided into 4 groups receiving(More)
A soluble fraction from human frontal cortex with molecular weight less than 10 kD was tested for the presence of endogenous substances capable of modulating the [3H]-QNB binding to crude P1 + P2 fractions from the same region. The soluble fraction was able to decrease [3H]-QNB binding in a dose-response manner with an IC50 of about 30 micrograms/ml. The(More)
