Abstract: Objective To explore effects of hcmoperfusion on toxic ingredients in plasma of rabbiis with a-cute intoxication of Radix Aconiti Kusmezoffii Monkshood.Method Sixteen male Japanese Giant Ear Rabbits were randomly divided into acute poisoning(AP)group and acute poisoning + hemoperfusion(AH)group(8 an-hnals in each group).Acute poisoning models were established in rabbits of both groups with intragastric adminis-tration of Radix Aconiti Kusmezoffii Monkshood liquid in dose of 1 mL/kg in order to produce arrhythm which oc-curred within ode hour after intragastric administration was regarded as the criteria of successful animal model.and then hemoperfusion with active carbon was performed for 2 hours in AH group.The pathological chanses of brain,myocardium and hepatic tissues were observed.The plasma concentrations of toxicants including mesaconitine,a-conitine and hypaconitine were measured by using HPLC-MS at 1 h,2 h,3 h,and 6 h after poisoning.Student's T test was used to identify the significance.Results The brain.myocardium and hepatic tissues of the rabbits in AP group showed hyperemia and edema which were attenuated after hemoperfusion.The plasma concentrations of mesaconitine,aconitine and hypaconitine revealed no significant differences between AP group and AH group with-in one hour after poisoning(P>0.05),while at 2 h and 3 h after poisoning,the plasma concentrations of mesaconitine were(2.11±1.08)ng/mL,(2.02±1.46)ng/mL,respectively,aconitine(39.70±9.31)ng/mL,(19.71±16.06)ng/mL,respectively,and hypaconitine(1.70±0.71)ng/mL,(2.12±1.33)ng/mL,respec-fively in AH group,and they were significantly lower than those in AP group(P<0.05).Conclusions The the plasma concentrations of mesaconitine,aconitine and hypaconitine were lower and the histopathological changes were attenuated after hemoperfusion.Hemoperfusion is a good intervention for acute intoxication of Radix Aconiti Kusmezoffii Monkshood.
