Background: Epilepsy is the fourth most frequent neurological disorder worldwide. Epilepsy can be diagnosed if someone has two or more spontaneous seizures. Subtypes M1 and M3 of the receptor are affected by pilocarpine, with the M3 receptor having the ability to activate phospholipase C. In this way, the second messenger's inositol triphosphate, diacylglycerol, calcium, and protein kinase are produced. Because of this, M3 cholinergic agonists cause calcium to be upregulated, leading to smooth muscle contraction. Ursodeoxycholic acid is an effective drug for treating cholestatic liver disease. There are a number of interconnected and synergistic ways in which ursodeoxycholic acid affects the liver.
Method: Thirty adult male Wistar rats, weighing 200 ± 20 g, were utilized in this study. Group I (negative control): Rats will be received of N/S (0.5 ml/kg)
Group II (Sco+LiCa+Pilo): Rats received LiCa, 127 mg/kg, followed by pilocarpine administration (30 mg/kg).
Scopolamine (1 mg/kg in rats) is also given to the rats 30 min before pilocarpine administration.
Group III(Diazepam ):Epileptic rats treated with diazepam (20 mg/kg) were started 2 h after the beginning of SE. Group IV (min. dose of UDCA): Epileptic rats will receive UDCA 25 mg/kg/day. Group V (max. dose of UDCA): Epileptic rats will receive UDCA 100 mg/kg/day .
Result: Based on measurement of markers: TNF-α and GSH, we reported increase the level of TNF-α and decrease the level of GSH when given pilocarpine, while we found rise in the GSH level and decrease in the level of TNF-α in UDCA-treated group
Conclusion: It can be concluded that the UDCA improves the biochemical alterations (decreases GSH & increases TNF) that occur after S.E., and UDCA has the same effect when compared with the diazepam effect.
