肺结核,特别是有组织破坏的患者,抗菌疗法常不能取得满意效果。超声能提高组织屏障的通透性,改变结缔组织的功能状态,提高细胞成分的吸附作用和淋巴细胞的增殖功能,从而刺激受作用局部及与之有反射联系的组织器官的物质代谢,有助于组织的修复。 通常治疗所用超声属中频波段(830～880kHz),透入组织较浅,约3～5cm,而低频波段(<100kHz)的超声则可深达12cm,且已有用于泌 Tuberculosis, especially in patients with tissue damage, antimicrobial therapy often can not get satisfactory results. Ultrasound can improve the permeability of the tissue barrier, change the functional status of connective tissue, increase the adsorption of cellular components and lymphocyte proliferation, thus stimulating the metabolism of the material affected by the local and reflex connected tissues and organs, Repair of the organization. Ultrasound is usually used in the treatment of the middle frequency band (830 ~ 880kHz), penetrate the tissue is shallow, about 3 ~ 5cm, while the low frequency band (<100kHz) ultrasound is as deep as 12cm, and has been used for secretion
