Abstract
Ultrasound treatment (1.5 W/cm2, 1.9 MHz, C.W.) for 15 minutes either before or after x irradiation reduced the TCD50 of sarcoma-180 by approximately 40% while similar ultrasound treatment for up to 30 minutes did not reduce the TCD50 of the C3HBA mammary adenocarcinoma. Water bath heating (44.5 degrees C for 15 minutes) after x irradiation reduced the TCD50 of both tumors. Ultrasound alone for up to 30 minutes had no effect on growth or cure rate of either tumor.
摘要
在X射线照射前或照射后进行超声治疗（1.5瓦/平方厘米，1.9兆赫，连续波）15分钟，可使肉瘤-180的半数致死量（TCD50）降低约40%，而类似的超声治疗长达30分钟却不会降低C3HBA乳腺腺癌的TCD50。X射线照射后进行水浴加热（44.5摄氏度，15分钟）可降低两种肿瘤的TCD50。单独进行长达30分钟的超声治疗对两种肿瘤的生长或治愈率均无影响。
