  1. Mean values and deviation from the mean value of the normalized Ca-signal intensities determined for different groups and different times after osteoporosis induction and the corresponding absolute HAP content (wt%) evaluated by equation (1). ∆HAP is given by the standard error of the slope of Figure 3c.
