Objective To observe the influence of gene transfection of inducible nitric oxide synthase to the transplanted human laryngeal squamous carcinoma in nude mice, to investigate the expression and the correlayion of iNOS and p53, and to proke into the possible apoptosis mechanism. Methods Transfect the gene of iNOS to Hep-2 human laryngeal cancer cell, sieve out positive clone cell and amplify.

The main content of this dissertation includes: 1. Research on the theory of ultrasonic power supply, introduce its development process. On the basis of these, fix on the scheme of medical ultrasonic low-power supply. 2. According to the principle of modularized design, divide medical ultrasonic low-power supply into four parts. They are power amplify circuit, power control circuit, frequency automatic tracking circuit and matching circuit. Separately research on their theories and design their circuits and necessary programs, especially, effectively resolve the problem tracking the supersonic vibration system with a narrow syntony frequency bandwidth and a high swing. 3. The matching experiments gain good result, and prove that medical ultrasonic low-power supply is entirely up to the mustard on intellectualization, wide band of working frequency, steady output and high efficiency.
