RESUMEN
Objective To study the analgesic and anti-inflammatory effects in vivo of the total alkaloids in Stephania kwangsiensis (TARS).Methods Mice were respectively ig with high,middle,and low doses of TARS.The analgesic effects of TARS were evaluated by the formaldehyde induced pain method and tail-immersion response induced by hot water in mice,and anti-inflammatory effects were observed by cotton ball granuloma,egg white induced paw swelling method in mice.Results TARS could significantly inhibit formaldehyde induced pain in mice,reduce the hind licking times,extend tail withdrawal time induced by hot water,obviously reduced the formation of granulomatous in mice;Inhibited egg white induced paw swelling.Conclusion TARS has significant analgesic and anti-inflammatory effect.
