Research on establishing of rabbit VX2 carcinoma model and monitoring with color Doppler energy ultrasound technique / 重庆医科大学学报

ABSTRACT

Objective:To explore a method of high successful rate to establish the rabbit VX2 carcinoma model, and monitor the tumor with ultrasound technique.Methods:Tumor block transplanting method was used to make the rabbit VX2 carcinoma model,and verify the tumor in rabbit′s liver with pathological section.Ultrasound technique was applied to detect liver echo, size and echo of tumor,generation and changing of blood vessels in tumor and to find out the characters of the rabbit VX2 carcinoma.Results:The rabbit VX2 carcinoma model was made successfully with tumor block transplanting method, and the success rate was 100%.The ultrasound technique could measure the size of tumor exactly, and it could monitor the changes of the echo and tumor blood vessels in carcinoma exactly at the right time.Conclusion:Tumor block transplanting method is a simple method to make rabbit VX2 carcinoma model with high successful rate. The ultrasound technique is an accurate、convenient and non-invasive method to monitor the carcinoma and blood vessels in tumor.The results provide experimental evidence in evaluating the efficacy of new techniques and therapeutics for liver carcinoma.
