We examined the effect of 5% deuterium oxide (D20) in drinking water on systolic blood pressure, platelet cytosolic free calcium, aortic calcium uptake and plasma insulin, glucose and triglycerides in rats with fructose-induced hypertension. Eighteen male Wistar-Kyoto (WKY) rats, age 8 weeks, were divided into 3 groups of 6 animals each. Animals in group I were given water; group II, 8% fructose and group III, 8% fructose + 5% D20 as their drinking water for the next 15 weeks. Systolic blood pressure in the fructose treated rats was significantly higher (p < 0.01) than in animals on water after 2 weeks and remained higher throughout the study. At 15 weeks, systolic blood pressure, platelet cytosolic calcium, aortic calcium uptake and plasma glucose, insulin and triglycerides were significantly higher (p < 0.01) in the fructose treated rats compared with rats from other groups. Deuterium oxide given together with fructose prevented development of high blood pressure and the associated increase in platelet cytosolic calcium, aortic calcium uptake and plasma triglycerides. D20 treatment did not prevent fructose induced increases in plasma insulin and glucose. The parallel increase in systolic blood pressure, cytosolic free calcium, and in vascular calcium uptake suggests that an increased cytosolic free calcium is involved in the pathophysiology of hypertension. D20 prevents this hypertension by normalizing cytosolic free calcium.
