Figure 3: Thiamine treatment effect on blood lead levels (BLL) (A) and ALAD activity (B) in monocasters. Bars represent mean±SD of BLL and per cent decrease of BLL during the course of experiment. A significant decrease in BLL of monocasters on supplementation with thiamine as the treatment regimen continues. Different superscripts represent significant difference at P < 0.05. ALAD, amino levulunic acid dehydratase; SD, standard deviation. Source: Reproduced with permission from Ref. 14.
