ABSTRACT
Objective To evaluate the value of high frequency color Doppler ultrasound in detecting the growth of orthotopic prostate tumor in nude mice. Methods Thirty-five orthotopic prostate tumor models of BALB/c nude mice were established. High frequency color Doppler ultrasound was used to monitor the growth of tumors in five randomly selected BALB/c nude mice after 2 - 8 weeks. After examination,the nude mice were immediately sacrificed under narcotism. The tumors were dissected, fixed and embedded. The sections were stained by HE and reviewed under microscope as the gold standard of detecting the growth of orthotopic prostate tumors. The growth curves were recorded and analyzed. Results High frequency color Doppler ultrasound can be used to observe the size, resonance, blood supply and necrosis of tumors. The tumors grew fastest in 4~6 weeks after injection. After seven weeks, necrosis can be found in the center of the tumors while the boundary of the tumor was not clear. Conclusions High frequency color Doppler ultrasound can be a reliable method to monitor the growth of orthotopic prostate tumor in BALB/c nude mice.
