Table 4.

Ca²⁺ content at different time points ( $\bar{x} \pm SD$ , n=3, μmol/mL)

Group	2 d	5 d	7 d
Control group	0.0346±0.0128	0.1448±0.0443	0.2873±0.0636
Experimental group	0.0714±0.0194^a	0.3966±0.0754^a	0.5874±0.1075^a

Note: Significant difference (P<0.05) was found between the experimental group^a and control group at each time point.

Abbreviations: SD, standard deviation; d, days.
