Fig. 4. : inhibitory effect of Microtus fortis -albumin on schistosomula in vitro. This diagram showed that when the target protein concentration was equal or greater than 1.25 mg/mL, significant difference of schistosomula mortality rate was observed when compared with negative control and the dead rate of schistosomula raised markedly along with the rise of albumin concentration (asterisk means p < 0.05, compare with negative control). Results represented mean ± standard deviation for triplicates. N: negative control; P: positive control.
