Analgesic effect of silymarin in chicks

Abstract

There were no studies about the analgesic effect of silymarin in the chicken. This study examined antinociceptive effect of silymarin given intraperitonially in 7-9 day-old chicks. The median effective dose of silymarin for the induction of analgesia to electric stimulation in the chicks was 65.3 mg/kg. Silymarin at 60, 120 and 240 mg/kg revealed analgesic effect to electric stimulation in chicks in dose dependent manner in comparison with the control group. The analgesic effect of silymarin at 120 and 240 mg/kg started at 15 min after injection and lasted after over 120 min of injection were as silymarin at 60 mg/kg the analgesic effect started at 15 min after injection and declined before 120 min of injection. The peak of analgesic effect for 60, 120 and 240 mg/kg were at 60 min after injection. These results indicate that silymarin have an analgesic property in the chicks model.
