  • 视网膜色素变性合并青光眼5例

    本文报告了视网膜色素变性合并青光眼患者5例,其中男性2例,女性3例。视网膜色素变性的发病年龄为15~33岁,平均年龄为20.8岁;青光眼的发病年龄23~51岁,平均年龄37.6岁;青光眼的类型:闭角型青光眼4例,开角型青光眼1例。本文就视网膜色素变性的遗传及视网膜色素变性合并青光眼的发病机理等问题进行了讨论。 (中华眼底病杂志,1992,8:183-184)

  • Establishing A VX2 Rabbit Liver Tumor Model by Injecting Tumor Tissue Under The Guidance of Ultrasound

    Objective To establish a VX2 liver tumor model in rabbits under guidance of ultrasound mini-invasively, and to evaluate the imaging characteristics of VX2 liver tumor on ultrasound, CT scanning and angiography,respectively. Methods VX2 tumor tissues that were planted intramuscularly in the rabbit’s hind leg, were resected and cut into small pieces in 0.5 mm×0.5 mm×0.5 mm, and were inoculated into the left lobes of livers in 60 New Zealand rabbits under the guidance of ultrasound. The achievement ratio of the inoculated tumors growing in the rabbit livers were measured, and the imaging characteristics of the tumors on ultrasound, CT scanning and angiography were observed and then were evaluated 2 weeks later. Results The achievement ratio of establishing a liver tumor model under the guidance of ultrasound was 95% (57/60). The average physio-life span of the model rabbits was (45±8) d. Ultrasound showed that the tumor in the rabbit liver was a single spherical or sphere-alike hypoechoic nodus, and there were higher blood flow signals in and around the nodus. VX2 tumor in the liver appeared as a solitary low density nodus on unenhanced CT scanning, and the hepatic arteriography showed that the tumor was rich of blood vessels, which built the disordered vasoganglion. Tumor was maily stained at the edge of the nodus. Conclusion It may be simple and effective to estabish a rabbit liver tumor model by inoculating VX2 tumor tissue under the guidance of ultrasound and the achievement ratio of such method was relatiely high. And the imaging characteristics of the tumor was similar to that of human primary liver carcinoma.
