title: Measurement of regional bone blood flow in the rabbit mandible using the hydrogen washout technique.
abstract: This investigation involved quantitating blood flow in rabbit mandible using the hydrogen washout technique. The animal was ventilated with a H2/O2 gas mixture. Hydrogen concentration was monitored by surgically implanted platinum electrodes. The Fick principle was used to interpret the H2 washouts. The following mean flows were obtained: Cortical bone, 4.49 ml/100g/min; condylar bone, 8.22 ml/100g/min; and alveolar bone, 18.33 ml/100g/min. This technique proved repeatable and compared well with other studies.
