Background & aim: Catatonia is one of the major signs of Parkinson’s disease which is due to impaired dopamine in extrapyramidal system. This study was performedconducted to elucidate the role of Gallic acid (GA) on perphenazine (PPZ)-induced catatonia in rat.
Methods: This is an experimental study conducted in 2019,48 Wistar male rats weighting 180-220 g were randomly divided into 6 groups (n=8) in each group. Animals were pre-treated with a single dose of normal saline (5ml/kg), most effective dose of bromocriptine (30mg/kg) and GA (100, 200, 400 and 600 mg/kg) via intraperitoneal (IP) route. PPZ (5 mg/kg, IP) was administered after 30 minutes of first injection to induce catatonia. The scoring method of Morpurgo was used to determine the muscular rigidity of animals.
Ethical consideration: This study obtained its ethical approval form the Research Ethics Committee. (Code: IR.MAZUMS.RIB.REC.1398.056).
Results: The results indicated that the 100mg/kg GA treated group had no significant reduction in catatonic responses after PPZ administration in comparison with negative control group while the groups that received 400 and 600mg/kg of GA showed significant difference (p<0.05) at all the time points.
Conclusion: The results revealed that GA had protective effect on catatonia induced by PPZ in rats. Hence, GA may probably be supportive for reducing catatonia in Parkinsonism.
