WOS: 000460712900014PubMed ID: 30641413Purpose: Anti-epileptic drugs have been widely used in children with epilepsy. Although several studies have investigated the role of oxidative stress and the effects of antiepileptic drugs on several oxidative markers in epilepsy, adequate information is not available on this issue. This study aimed to investigate the changes in thiol disulphide homeostasis in children with epilepsy under two commonly prescribed AED monotherapies, carbamazepine and valproic acid. Methods: A hundred and one children with epilepsy using valproic acid or carbamazepine and 58 healthy children were included in this study. Of the 101 patients with idiopathic epilepsy, 58 were on valproic acid monotherapy and 43 patients were on carbamazepine monotherapy. The total thiol, native thiol, and disulphide levels were measured and the disulphide/native thiol, disulphide/total thiol and native thiol/total thiol ratios were calculated in both groups. Results: The total thiol and native thiol levels of the valproic acid treated group were significantly lower than the control group (p < 0.05). The native thiol level of carbamazepine treated group was lower than the control group without a significance (p = 0.123). Disulphide level, disulphide/native thiol and disulphide/total thiol ratios were significantly higher and native thiol/total thiol ratio was significantly lower in both valproic acid and carbamazepine treated group compared with the control group. Conclusion: Thiol/disulphide homeostasis is impaired in children with idiopathic epilepsy using valproic acid or carbamazepine. Valproic acid which is frequently used in childhood epilepsy may modify this balance more than carbamazepine monotherapy. More importantly, the new method used in our study proposes a promising, practical and daily applicable test for evaluating oxidative stress in these patie

Effects of recurrent sevoflurane anesthesia on cognitive functions with streptozotocin induced Alzheimer disease

OBJECTIVE: We aimed to investigate the effects of recurrent sevoflurane anesthesia on cognitive functions in Alzheimer Disease. MATERIALS AND METHODS: Rats were divided into 4 groups as followed: control (Group C), sevoflurane (Group S), Alzheimer's (Group A) and Alzheimer's + sevoflurane (Group AS)]. Cognitive functions were evaluated with Radial Arm Maze Test (RAMT). Alzheimer model was created by administering 3 mg/kg (10 mu l) STZ. Sevoflurane was administered to S and AS groups. Serum samples and hippocampus tissues were analyzed. RESULTS: In RAM test, the entry-exit data were significantly decreased in A and AS groups. After the 2nd and 3rd administration of anesthesia, the numbers were significantly decreased in Group S. Glial-fibrillary-acidic protein levels were significantly higher in AS compared to the C and S groups. The brain tissue caspase 3 activity was less than 1\% in all rats in the Group C, 3 \% in 2 rats and 1 \% in 1 rat in the Group AS. In A and AS group, serum catalase, myeloperoxidase and ferroxidase activities were found to be higher than in the other groups and myeloperoxidase activity was higher in the AS than in the A Group. Serum native thiol, total thiol and disulfide levels were found to be significantly different in the A and AS groups. CONCLUSION: Sevoflurane anesthesia negatively affected the cognitive functions
