Figure 2.

Effect of Pb-exposure and calcium supplementation on maternal body weight gain (%) of rats. Rats were exposed to either deionized drinking water (control) or Pb-acetate (0.2%) or calcium together with Pb in deionized water from gestational day 6 (GD 6) to GD 21 through drinking water. Values are mean ± SD of eight (n=8) observations. The values marked with “asterisk” are significantly different from corresponding controls as evaluated by the ANOVA followed by Student-Newman-Keuls (SNK) post hoc test (p<0.05).
