[Effect of carbohydrates on arterial pressure. An experimental study]

The effect of incorporation of sugar in a diet on a level of arterial pressure in 120 rats Wistar was examined. The replacement of 50% of starch by sugar in the balanced diet with a normal content of protein and white salt did not have a profound influence on a pressor effect. However on a background of an abundant content of white salt in a diet protein and fat balanced, the incorporation of sugar in a diet resulted in additional increase of arterial pressure (+27.27 mm of a hg) in comparison with a saline diet without sugar (p < 0.001). The sugary diet with normal content of white salt bring to evident pressor effect (+6.60 mm of a hg) at deficiency of protein (p < 0.001), though on others variants of protein deficiency diets the slight tendency to a drop of arterial pressure was observed. The causes of ambiguous changes of arterial pressure in a protein deficiency remain unclear.
