Effect of high calcium (3%) intake on blood pressure and intracellular pH, Na(+)-H+ exchange activity, cytosolic free calcium concentration in stroke-prone spontaneously hypertensive rats (SHRSP-Ca) is compared with sex-, ag-matched SHRSP and WKY rats without high calcium intake. The results showed that high calcium intake significantly suppressed increase in blood pressure and decreased cytosolic free calcium concentration after it was given to SHRSP-Ca for 6 weeks, while plasma calcium was increased. The intracellular pH tended to be in the normal range of WKY rats. Na(+)-H+ exchange activity was slightly decreased. Correlationship between blood pressure and intracellular pH, Na(+)-H+ exchange activity and cytosolic free calcium concentration were discussed.

UI MeSH Term Description Entries
D006973 Hypertension Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.

D002118 Calcium A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
