[In Vivo]

Ectylurea (0-500 mg/kg, i.p., once, 20 min) can significantly cause changes in motor coordination in mice in a dose dependent manner[2]. Animal Model: Male albino Swiss mice (18-23 g)[2] Dosage: 0, 100, 250 and 500 mg/kg Administration: Intraperitoneal injection, 20 min Result: Influenced on the performance of naive mice on the accelerating rotarod in a dose dependent manner.
