As shown in Figure 6, the intracellular free Ca2+ concentration was lowest in the model control (MC) group. The treatment of AHG resulted in dose-dependent increase in the amount of Ca2+ when compared with MC group. Particularly, the level of Ca2+ in AHG group at 10 mg/kg nearly reached the level in NC group. These results showed that AHG was capable of reversing the decrease of Ca2+ concentration in CY-treated mice to the normal level.
