The Effect of Prolonged Administration of Ethanol

چکیده
tensin, a slight but not significant decline in cardiac contractility was observed. Activities of various intramitochondrial and extramitochondrial enzymes were measured in both groups. After alcohol administration, the primarily intramitochondrial isocitrate dehydrogenase diminished. ATP in heart muscle of dogs exposed to alcohol declined, and mitochondrial oxygen consumption and respiratory control indices diminished. These observations suggest that the primary lesion leading to alteration of myocardial performance is a biochemical malfunction of the mitochondria, which at this early stage is not reflected in changes in myocardial contractility.

The Effect of Acute Ethanol and Gabapentin Administration on Spatial Learning and Memory
Introduction: Patients with epilepsy can have impaired cognitive abilities. Many factors contribute to this impairment, including the adverse effects of antiepileptic drugs like Gabapentin (GBP). Apart from anti-epilectic action, Gabapentin is used to relieve ethanol withdrawal syndrome. Because both GBP and ethanol act on GABA ergic system, the purpose of this study was to evaluate their effe...
