摘要
本研究以狗20只、恒河猴6只作实验动物,分组作下牙槽动脉结扎或下颌体附丽软组织剥离,用核素(^(90m)Tc-phosphate)测定在上述手术后下颌体的血供情况。通过统计分析,发现下牙槽动脉是下颌体血供的主要来源,下颌体附丽软组织在下颌体前份的血供中起较重要的作用,下颌骨内血供分布不均。
20 mongrel dogs and 6 monkeys were used as experimental animals.The lower alveol-ar artery was ligated or the soft tissue inserting to the mandibular body Was stripped.Activity of bone in each region of mandibular body was measured 180 minutes(for dogs)or 120 minutes(for monkeys)after intravenous injection of ^(99m)Tc-phosphate.Comparingthe findings with matched data by means of significance test,the authors have evaluatedobjectively the roles played by the lower alveolar artery and the soft tissue inserting tothe body in the blood supply of the mandibular body,and the distribution of blood supplyin the whole mandible.
