Role of Calcium Channels in Heavy Metal Toxicity

In early work, the influx of Pb and Cd into mammalian cells was frequently ascribed to permeation through calcium channels, and in particular L-type DHP-sensitive VDCC [16, 18, 20, 32]. More recently other types of VDCC, different from the classical DHP19, 33

Calcium sulfate | CaSO4 - PubChem

The use of calcium sulfate (plaster of Paris) has been advoed to repair bony defects because of its unique capability of stimulating osteoneogenesis. Plaster of Paris can be used as a bony alloplast and it can be analyzed histologically. Sinus roentgenograms and technetium Tc 99m medronate bone scanning further support the use of plaster of Paris as an alloplast and assess its osteoneogenic

Role of Calcium Channels in Heavy Metal Toxicity

The role of voltage-dependent Ca channels (VDCC) in the merane permeation of two toxic metals, lead (Pb) and cadmium (Cd), was studied in mammalian cells. Both metals interact with Ca-binding sites, but, while Cd influx appears to occur mainly through the same pathways as Ca, Pb is also rapidly taken up by different passive transport systems. Furthermore, I compared the effect of Cd in two
