✦ Synopsis

Samples of distributed water have been taken from 127 restaurants of the land forces selected in di!erent administrative districts in France to assess the contribution of water to recommended daily allowances (RDA) in calcium and magnesium. Mean levels of calcium and magnesium were found to be, respectively, 63.8$37.7 and 5.4$2.5 mg/l, with a signi"cant correlation between calcium and magnesium content (r"0.49, P(0.001). The softest waters are found in areas where soil is granitic or sandy. Daily consumption of 1 l of tap water provides on an average 7.1 and 1.3% of RD in calcium and magnesium.

## Abstract The extracellular concentrations of Ca^2+^ and Mg^2+^ are well known to play important roles in the function of the central nervous system. We examined the effects of extracellular Ca^2+^ and Mg^2+^ on ATP release and intercellular signaling in astrocytes. The extent of propagation of i
