Radiation dose rates were evaluated in three areas neighboring a restricted area within a 20- to 50-km radius of the Fukushima Daiichi Nuclear Power Plant in August-September 2012 and projected to 2022 and 2062. Study participants wore personal dosimeters measuring external dose equivalents, almost entirely from deposited radionuclides (groundshine).(More)
The effects of sodium depletion on plasma norepinephrine (NE) kinetics were studied in 14 patients with essential hypertension using the steady state NE infusion technique on the theoretical basis of a two-compartmental open model. The calculated half time of rapid removal phase (t 1/2 alpha) of plasma NE was significantly delayed in the hypertensives (1.20(More)
Two women who first had the clinical features of primary aldosteronism in the postpartum period are described. Their gestations were virtually uneventful. After delivery, however, progressively severe hypertension (Joint National Committee VI, stage 3) with hypokalemia developed. Pregnancy may conceal the clinical symptoms of primary aldosteronism that(More)
The effects of epinephrine (E) on plasma norepinephrine (NE) concentrations and cardiovascular responses before and after beta-blockade were studied in 36 patients with essential hypertension and 10 age-matched normal controls. The resting plasma NE and E were significantly higher in the borderline hypertensives (251 +/- 21 (SE) pg/ml, p less than 0.005; 57(More)
The effects of endogenous epinephrine (E), released by glucagon injection, and exogenously infused E on plasma norepinephrine (NE) and cardiovascular responses before and after beta-blockade were studied in patients with essential hypertension and in age-matched normotensive controls. The resting plasma NE and E levels were significantly higher in the(More)
