Elevated arterial pressure had long been surmised from the strength of the pulse. Its association with contracted kidneys and hypertrophied hearts was described by Richard Bright (1789-1858). Microscopic observations of the narrowed and obliterated vasculature initially observed in the kidneys of Bright's disease, and subsequently throughout the body, launched clinical ...

BACKGROUND: Australian Aborigines are experiencing epidemic proportions of renal disease, marked by albuminuria and, variably, hematuria. They also have high rates of low birth weight, which have been associated with lower kidney volumes and higher blood pressures. The authors evaluated relationships between kidney volume, blood pressure, albuminuria, and hematuria in ...
