Abstract:
Objective To explore the effect of praziquantel on schistosomal ovum granuloma in the lung of mice.Methods Forty-eight mice were divided into 4 groups.Group A:first,the mice were injected with schistosomal ova hypodermicly in abdomen and 10 days later,injected with schistosomal ova intravenously in the cauda;Group B:in addition to the injection of schistosomal ova as the same of Group A,the mice were administered with praziquantel [300 mg/(kg?d)] for 3 days from the last day of the intravenous injection of the ova;Group C:in addition to the injection of schistosomal ova as the same of Group A,the mice were administered with praziquantel(75 mg/kg,B.i.d.)for 5 days weekly until the mice were sacrificed;Group D:the same as Group C but praziquantel was given to the mice from the 29th after the intravenous injection of the ova.Three mice of each group were sacrificed on the 7th,14th,28th,56th day after the intravenous injection of the ova and the lung tissues were fixed with formalin and the slices were HE stained.Fifteen-thirty pieces of schistosomal ovum granuloma were examined and their areas were measured and the mean areas of each group were calculated and compared.Results On the 7th,14th and 28th days after the intravenous injection of the ova,the mean area of schistosomal ovum granuloma in Group C was significantly less than that in Group A,and there was a significant difference between the two groups,P 0.05.On the 56th day,the mean areas of schistosomal ovum granuloma in Group B,C,D were significantly less than that in Group A,all P
