Effect of Ca²⁺ withdrawal on carmustine induced annexin V binding. Arithmetic means ± SEM (n = 4) of the percentage of annexin V binding erythrocytes after a 48 h treatment with Ringer solution without (white bar) or with (black bars) 100 µM carmustine in the presence (left bars, +Calcium) and absence (right bars, −Calcium) of calcium. * (p < 0.05), *** (p < 0.001) indicate significant difference from the absence of carmustine (ANOVA), ### (p < 0.001) indicates significant difference from the respective values in the presence of Ca²⁺.
