Abstract

|
This study was conducted to evaluate the effects of the salts fortified with Hizikia component on blood pressureand mineral composition in spontaneously hypertensive rats (SHR/NCrj) and normotensive rats (WKY/NCrj). The two speciesrats were assigned to three groups and were fed with drinking water to which Hizikia salts were added for 6 weeks. The finalblood pressures (BP) among groups of SHR were increased to 12, 4, and 21%, respectively. In terms of urine and fecalminerals, the Na+ contents in two species were significantly higher in the control than in the salt groups, and vice versa withregard to the K+ contents. The amount of excretion mineral was higher in urine than in feces. The Na+, Ca++ and Mg++contents of the liver in SHR were higher in the control than in the salt groups (p<0.05). The Na+ content of the kidney inSHR was higher in the control than in the salt groups, but the content was shown an opposite trend in WKY. The K+ contentswere higher in the low salt group (p<0.05). These results may indicate that the salts fortified with the Hizikia component maybe useful in lowering systolic blood pressure owing to the maintenance of positive mineral metabolism.
