Fig. 2

Graphical representation of kidney indices of experimental groups (kidney indices = kidney weight/body weight). A total of 24 rats were included per week. Kidney indices were calculated as the ratio of the combined weight of the right and left kidneys to the total body weight. (a p < 0.05; compared to control group, b p < 0.05; compared to CP group, c p < 0.05; compared to K group, d p < 0.05; compared to G group, e p < 0.05; compared to K + G group).
