[Effects of mebendazole on glucose, glycogen, lactic acid, and lactate dehydrogenase in Echinococcus granulosus cyst wall].
The glucose, glycogen, and lactic acid contents in Echinococcus granulosus cyst wall were 3570 +/- 623, 1276 +/- 126, and 267 +/- 29 micrograms.g-1, respectively. The lactate dehydrogenase (LDH) activity in the cyst wall was 4307 +/- 297 U/(min.mg protein). When infected mice were treated ig with mebendazole (Meb) 25 or 50 mg.kg-1.d-1 for 7-14 d, the glucose and glycogen contents in the cyst wall decreased markedly. No apparent changes in lactic acid and LDH activity were seen. The results suggested that Meb had no effect on glycolysis of the cyst wall, but it exhibited an inhibitory effect on the transport of exogenous glucose from the host to the cyst wall, which might further promote the decomposition of endogenous glycogen for energy supply and resulted in a decrease of endogenous glycogen content in the cyst wall.
