Efficacy of dapsone administered alone or in combination with diazepam to inhibit status epilepticus in rats.
Brain research(2018)
摘要
Status epilepticus (SE) is a serious medical condition, as it may trigger epileptogenesis. SE produces continuous generalized seizures resulting in irreversible brain damage. Therefore, the use of neuroprotective agents to prevent cell damage, may reduce the impact of SE. The use of diazepam (DZP), has shown limited neuroprotective effect in SE patients. According to previous reports, dapsone (DDS) is able to reduce both cell damage and seizures, when administered 30 min before the onset of seizures. This study is aimed to evaluate the ability of DDS, alone or in combination with DZP starting their administration once the SE is onset to evaluate the control of seizures in rats. Results showed a reduced convulsive electrical activity after 30 min, 1 and 2 h after SE induced by kainic acid (KA) administration, in the animals treated with DZP alone or in combination with DDS. At 24 h, we observed electrical activity similar to baseline in all groups receiving treatment. The animals treated with DDS and DZP alone or in combination showed an increase in the number of viable pyramidal cells but only the combination showed a lower number of damaged pyramidal neurons of hippocampal CA3. In conclusion, DDS plus DZP was able to control SE and to prevent SE-induced damage, when administered in combination with DZP. As DDS is already in use for patients with leprosy, that combination may be a safe, good option for human cases of SE.
