Figure 6.

Effect of a polyphenol-rich extract from the berries of Aronia melanocarpa (AE) on the “material” biomechanical properties of the femoral diaphysis in rats exposed to cadmium (Cd). The rats received 0.1% aqueous AE or not (“+” and “−”, respectively) and Cd in diet at the concentration of 0, 1, and 5 mg/kg. Data are represented as mean ± SE for eight rats, except for seven animals in the AE group, and the groups treated with the 1 and 5 mg Cd/kg diet alone after 24 months. Statistically significant differences (Anova, Duncan’s multiple range test): * p < 0.05, ** p < 0.01 vs. control group; ^‡ p < 0.05, ^‡‡ p < 0.01, ^‡‡‡ p < 0.001 vs. respective group receiving the 1 mg Cd/kg diet. Numerical values in bars indicate percentage change compared to the control group (↑, increase; ↓, decrease).
