title: The partition coefficients of 133Xe between human blood and bone.
abstract: The partition coefficients of 133Xe between blood and haematopoietic bone marrow and homogenised bone have been determined in vitro. The partition coefficient lambda 1 corresponding to haematopoietic marrow was 0.95 ml g-1 while that corresponding to homogenised bone was a function of age, lambda 2 = 3.11 + 0.049(age)(ml g-1). These data can be used for calculating regional blood flow in healthy human femur by means of a simple 133Xe radionuclide method.
