Mechanisms of the antihypertensive effects of dietary calcium and role of calcitonin gene related peptide in hypertension.

abstract：:Intra- and extra-cellular concentrations of calcium were measured in hippocampal neurons of areas CA1 and CA3 during 8 min ischaemia and short-term (up to 60 min) recovery. During an ischaemic insult, [Ca2+]i increased progressively and [Ca2+]e decreased. There were large interneuronal differences, although, in genera...
