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.
本研究采用氢洗脱技术对兔下颌骨的血流进行定量分析。动物通过H₂/O₂混合气体进行通气。通过手术植入的铂电极监测氢气浓度。利用菲克原理来解释氢气洗脱情况。获得了以下平均血流量：皮质骨，4.49毫升/100克/分钟；髁突骨，8.22毫升/100克/分钟；牙槽骨，18.33毫升/100克/分钟。该技术证明具有可重复性，且与其他研究结果比较良好。
