Epilepsy is a neurological disorder characterized by recurrent seizures. Although antiepileptic drugs (AEDs) reduce the frequency of epileptic seizures, they can cause renal and hepatic damage. Several preclinical studies have indicated that Gaertn (AMLA) exerts an anticonvulsant effect related to its tannin and polyphenol content. We aim to evaluate the anticonvulsant effects of chronic oral AMLA administration and its impact on biochemical and hematological parameters in rats. Twenty-eight male Wistar rats (250 to 300 g) were divided into four experimental groups (n = 7): vehicle (purified water), AMLA (500 and 700 mg/kg), and carbamazepine (CBZ) (300 mg/kg) as the pharmacological control of anticonvulsant activity. Treatments were administered orally every 24 hours for 28 days, while carbamazepine was administered every 48 hours for 5 days before the behavioral, biochemical, and hematological test. On day 29, Status epilepticus (SE) was induced using the lithium-pilocarpine model (3 mEq/kg, .. and 30 mg/kg, ..), after which the behavioral and biochemical effects were evaluated. The AMLA 500 mg/kg and CBZ 300 mg/kg groups presented fewer phase V seizures than the vehicle group did. None of the treatments modified biochemical or hematological parameters. AMLA could be considered as a potential alternative therapy for the treatment of epilepsy.
癫痫是一种以反复发作性癫痫发作为特征的神经系统疾病。尽管抗癫痫药物(AEDs)可降低癫痫发作的频率,但它们会导致肾和肝损伤。多项临床前研究表明,余甘子(AMLA)因其单宁和多酚含量发挥抗惊厥作用。我们旨在评估长期口服AMLA的抗惊厥作用及其对大鼠生化和血液学参数的影响。将28只雄性Wistar大鼠(250至300克)分为四个实验组(n = 7):溶剂对照组(纯净水)、AMLA(500和700毫克/千克)以及作为抗惊厥活性药理对照的卡马西平(CBZ)(300毫克/千克)。每24小时口服给药28天,而卡马西平在行为、生化和血液学测试前每48小时给药5天。在第29天,使用锂-匹鲁卡品模型(3毫当量/千克,……和30毫克/千克,……)诱导癫痫持续状态(SE),之后评估行为和生化效应。AMLA 500毫克/千克组和CBZ 300毫克/千克组的V期发作次数少于溶剂对照组。所有处理均未改变生化或血液学参数。AMLA可被视为治疗癫痫的一种潜在替代疗法。
