The aim of this study was to measure changes in the antioxidant systems of epileptic children who had been receiving either valproate or carbamazepine monotherapy for 2 years. For this purpose, levels of erythrocyte glutathione, glutathione peroxidase, superoxide dismutase, and serum lipid peroxidation in 25 healthy children and 27 children who had(More)
We have studied the effects of carbamazepine on thyroid function in sixteen recently diagnosed epileptic children and thirteen epileptic children receiving long-term carbamazepine therapy and compared these findings with the thyroid function of thirteen healthy control subjects. Thyrotropin (TSH), triiodothyronine (T3), thyroxine (T4), free triiodothyronine(More)
Some epileptic drugs may change antioxidant enzyme activities in humans and experimental animals. Recent studies suggest that membrane lipid peroxidation may be causally involved in some forms of epilepsy, and the differences are reported in free radical scavenging enzyme levels. GSHpX, SOD, GSH are important parameters of antioxidant defence mechanisms.(More)
Thyroid hormones and pituitary function were assessed in 49 children with epilepsy who were receiving either a single medication of carbamazepine, phenobarbital and valproate or a combination of carbamazepine with phenobarbital or valproate. All therapeutic regimens except valproate monotherapy were associated with low levels of circulating thyroxine, free(More)
This prospective study was carried out to determine changes in the antioxidant system in epileptic children receiving long term antiepileptic drugs (AEDs). Levels of erythrocyte glutathione (GSH), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and serum lipid peroxidation were determined in 25 healthy children and 30 epileptic children who had(More)
The effects of carbamazepine (CBZ) and sodium valproate (SV) monotherapy on visual evoked potentials (VEP) were studied in 18 epileptic children receiving CBZ and nine epileptic children receiving SV. Pattern reversal VEP were determined before the administration of antiepileptic drugs (AED) and 1 year later during which time the patients had received AED.(More)
Cystic leukoencephalopathy with megalencephaly is a newly described entity with mild clinical involvement. Patients suffer from developmental problems and seizures in childhood. Progression is gradual into adulthood. Typical magnetic resonance imaging findings include subcortical cysts and diffuse leukoencephalopathy. The etiology is unknown with possibly(More)
Melatonin is synthesized and released by the pineal gland in a circadian rhythm, and many of its peripheral actions are mediated via membrane MT1 and MT2 receptors. Apart from its metabolic functions, melatonin is a potent neuroprotective molecule owing to its antioxidative actions. The roles of MT1 and MT2 in the neuroprotective effects of melatonin and(More)
Because of their favorable action profiles in humans, both memantine and melatonin are particularly interesting candidates as neuroprotectants in acute ischemic stroke. Until now, the signaling mechanisms mediating memantine's neuroprotective actions remained essentially uninvestigated. In addition, we have combined memantine with melatonin, which is a(More)
PURPOSE To determine the possible effects of glutathione S-transferase (GST) M1, GSTT1 and GSTP1 genetic polymorphisms on the risk of developing age-related macular degeneration (AMD). PATIENTS AND METHODS This case-control study included a total of 120 patients with AMD (65 with dry-type AMD and 55 with wet-type AMD) and 198 disease-free controls. GSTM1(More)
