| Popis: | Organophosphates (OPs) and carbamates are acetylcholine esterase inhibitors (AChEIs), which can cause seizure and lethality. Anticonvulsant properties of potassium channel openers including cromakalim have been determined in previous studies. In the present experiment, the possible effect of cromakalim on the convulsion and death induced by OPs and carbamates was studied in mice. Dichlorvos (an OP, 50 mg/kg) and physostigmine (a carbamate, 2 mg/kg) were used to induce seizure in animals. Cromakalim at doses of 0.1, 10, and 30 µg/kg was injected 30 min before dichlorvos and physostigmine, and 5 min before glibenclamide (a potassium channel blocker, 1 mg/kg) administration. All injections were performed intraperitoneally. After drugs administration, the onset of convulsion, death, the severity of seizure, and rate of mortality were investigated. Results revealed that both dichlorvos and physostigmine induced seizure activity and lethality in 100% of the animals. Cromakalim at doses of 0.1, 10, and 30 µg/kg significantly increased the latency of both seizure and death (P |
