Figure 2: The effect of DSW treatment on serum ALP, Ca, and Mg activity. The serum ALP, Ca and Mg levels after 4 months DSW treatment was measured by ELISA assay. Serum ALP levels presented a significant decrease in DSW-treated mice (a). In contract, Ca and Mg showed no significant different in DSW group compared with control mice ((b) and (c)). Each bar represents the average from six animals; -test, * versus CTRL group.
