title: Effects of bleeding on mitochondrial ultrastructure in the avian kidney.
abstract: Three levels of hypovolemia were produced in awake and anesthetized domestic chickens by withdrawing 2.5, 5.0, or 10.0 ml blood per kg body weight. A commercial indirect blood-pressure monitor was unable to detect significant differences between hemorrhaged birds and age-matched controls. Perfusion-fixed kidney samples from unanesthetized birds had mitochondrial low-amplitude swelling in proximal tubular epithelial cells. This response was slight at the lowest bleeding level but was definite at the middle and marked at the highest bleeding levels.
