METHODS: Mice infected with the parasite for 8-10 months were treated i.g. with mebendazole (Meb) or praziquantel (Pra). The activities of GPI and GAPDH in the cysts were measured by the formation of NADH or NADPH. RESULTS: GPI activity in the cyst wall was 197 +/- 103 U, while that of GAPDH was 25 +/- 13 U. When infected mice were treated i.g. with Meb 25-50 mg.kg-1.d-1 for 7-14 d, no apparent effect on the GAPDH activity in the cyst was found. In mice treated i.g. with praziquantel (Pra) 500 mg.kg-1.d-1 for 14 d, the GAPDH activity in the cyst wall was inhibited by 26.5%. As to GPI activity only the group treated i.g. with Meb 25 mg.kg-1.d-1 for 14 d showed 33.2% inhibition of the enzyme in the collapsed cyst wall. CONCLUSION: GPI and GAPDH are not the major targets attacked by the antihydatid drug. UR - http://www.chinaphar.com/article/view/6538
