Figure 3From: The effect of high frequency steep pulsed electric fields on in vitro and in vivo antitumor efficiency of ovarian cancer cell line skov3 and potential use in electrochemotherapyTumor volume and growth curve at different observation time among groups. Each point on the figure represents the mean ± S.D. of six mice. SPEF with different frequencies showed significant antitumor efficiency in comparison to the control group (Dunnett's test, all P < 0.05). However, there was no difference in tumor responses among test groups (one-way ANOVA, all P > 0.05).Back to article page
