Figure 6.
(a) Changes in serum potassium level on day 6 of the experiment. Notes: each bar is expressed as mean ± SEM. Cisplatin vs. control group: ∗P < 0.05; CIS vs. (CIS/OELE-150 and CIS/OELE-300). CIS: cisplatin; OELE: Olea europaea leaf extract; ns: nonsignificant; n = 5 rats/group. (b) Changes in serum potassium level on day 15 of the experiment. Notes: each bar is expressed as mean ± SEM. Cisplatin vs. control: ∗∗∗P < 0.001; CIS vs. (CIS/OELE-150 and CIS/OELE-300): +++P < 0.001. CIS: cisplatin; OELE: Olea europaea leaf extract; ns: nonsignificant; n = 5 rats/group.
