چکیده
Because of the mutual relationship between neural inflammation and seizure, this study aimed to determine the effects of intracerebroventricular (ICV) injection of the steroidal and non-steroidal anti-inflammatory drugs on pentylenetetrazol (PTZ)-induced seizures during the estrous cycle in rats. A total of 105 adult female Wistar rats were selected and divided into seven groups, including the control (saline), ketorolac tris salt (7.5, 15, and 30 µg), and methylprednisolone acetate (0.15, 0.3, and 0.6 µg), each with four subgroups (proestrus, estrus, metestrus, and diestrus) and three replicates (n=5). After a week of acclimatization, the estrous phase determination and synchronization were performed. Acute epilepsy was inspired by the intraperitoneal injection of 80 mg/kg of PTZ 30 min after the ICV injection of ketorolac and methylprednisolone acetate. The initiation time of myoclonic seizures (ITMS), the initiation time of tonic-clonic seizures (ITTS), seizure duration (SD), and mortality rate (MR) were measured for 30 min. Data were shown as mean±SD and analyzed using One-way ANOVA followed by Tukey–Kramer multiple comparison post hoc test (P<0.05). According to the results, ketorolac (15 and 30 µg) and methylprednisolone acetate (0.3 and 0.6 µg) significantly increased the ITTS and ITMS but decreased SD during the estrous cycle, compared to the control (P<0.05). Moreover, MR and SD were significantly decreased by ketorolac (7.5, 15, and 30 µg) and methylprednisolone (0.3 and 0.6 µg), compared to the control during the estrous cycle (P<0.05). Therefore, it seems that both ketorolac and methylprednisolone possess dose-dependent anticonvulsant effects that may decrease neural inflammation.
