Epilepsy is one of the most common serious neurological conditions. The current therapeutic treatment of epilepsy with modern antiepileptic drugs is associated with side effects, dose-related and chronic toxicity, and teratogenic effects and in approximately 30% of the patients is ineffective. is used in Iranian traditional medicine for treatment of different diseases like back pain and seizure.
In this study, anticonvulsant effects of hydroalcoholic extract of rhizomes were examined by using pentylentetrazole (PTZ) model in mice. rhizomes extract (200, 400 and 600 mg/kg), diazepam (1 mg/kg) and normal saline (10 mL/kg) were injected (ip) 30 minutes before PTZ (90 mg/kg, ip). The time taken before the onset of clonic convulsions, the duration of colonic convulsions, and the percentage of seizure and mortality protection were recorded. For further clarification of the mechanism of action for , flumazenil (2 mg/kg, ip) and naloxone (5 mg/kg, ip) were also injected 5 minutes before extract.
extract at the doses of 200 and 400 mg/kg prolonged the time of onset of seizure and decreased the duration of seizures compared to control (saline) group ( < 0.05). At the dose of 600 mg/kg, percentage of seizure protection was 16.66%. Naloxone and flumazenil could suppress anticonvulsant effects of .
It seems that could be a good candidate and be useful for seizure control and treatment, and in these effects, opioid and benzodiazepine receptors might probably be involved.
癫痫是最常见的严重神经系统疾病之一。目前使用现代抗癫痫药物治疗癫痫会产生副作用、剂量相关的慢性毒性、致畸作用,并且在大约30%的患者中无效。[某种植物]在伊朗传统医学中用于治疗背痛和癫痫等不同疾病。
在本研究中,通过戊四氮(PTZ)模型在小鼠中检测[某种植物]根茎水醇提取物的抗惊厥作用。在注射PTZ(90mg/kg,腹腔注射)前30分钟,腹腔注射[某种植物]根茎提取物(200、400和600mg/kg)、地西泮(1mg/kg)和生理盐水(10mL/kg)。记录阵挛性惊厥发作前的时间、阵挛性惊厥的持续时间以及癫痫发作和死亡保护的百分比。为了进一步阐明[某种植物]的作用机制,在注射[某种植物]提取物前5分钟还腹腔注射了氟马西尼(2mg/kg)和纳洛酮(5mg/kg)。
与对照组(生理盐水)相比,200和400mg/kg剂量的[某种植物]提取物延长了癫痫发作的起始时间并缩短了癫痫发作的持续时间(P<0.05)。在600mg/kg剂量下,癫痫发作保护率为16.66%。纳洛酮和氟马西尼可抑制[某种植物]的抗惊厥作用。
似乎[某种植物]可能是控制和治疗癫痫发作的良好候选药物,在这些作用中,阿片类和苯二氮䓬受体可能参与其中。
