The overall logistic fit between percentage toxicity (Y) and log concentration of ivalin (X) was highly significant ( p < 0.001) for all the different exposure times.
The overall logistic fit between percentage toxicity (Y) and log concentration of ivalin (X) was highly significant ( p < 0.001) for all the different exposure times.
Although the increase in susceptibility of H9c2 cells to parthenolide, over time, was not as noticeable as compared with ivalin, based on the statistical ranges of the EC 50 s, there was a definite trend ( Table 1 ).
