目的
2
探索光声层析成像(photoacoustic tomography,PAT)和多光谱光声层析成像(multispectral optoacoustic tomography,MSOT)在精索静脉曲张大鼠模型中进行睾丸结构和功能成像的可行性。
方法
2
将18只SD大鼠随机分为3组(空白组、模型组、迈之灵组),每组6只。模型组、迈之灵组均采用缩窄左肾静脉并结扎左侧精索静脉侧支方法造模,经过4周相应措施干预后,比较实验大鼠左侧睾丸的PAT/MSOT图像、氧代谢及氧化应激水平,研究不同干预措施实验大鼠的睾丸成像特征。
结果
2
PAT/MSOT能对大鼠睾丸结构进行清晰成像,能够反映睾丸内的氧代谢水平。
结论
2
PAT/MSOT可检测精索静脉曲张引起的睾丸结构和功能改变,是一种简易、无创、安全的新型睾丸评估方法。
Objective
2
To explore the feasibility of photoacoustic tomography(PAT) and multispectral optoacoustic tomography(MSOT) for testicular structure and function imaging in a varicocele rat model.
Methods
2
Eighteen SD rats were randomly divided into blank group,model group,and Aescuven forte group,with 6 rats in each group. In the model group and Aescuven forte group,a varicocele rat model was established by narrowing the left renal vein and ligating the left spermatic vein. After 4 weeks of intervention,the PAT/MSOT image,oxygen metabolism,and oxidative stress levels of rat left testicle were compared to investigate the testicular imaging characteristics of rats with different interventions.
Results
2
PAT/MSOT provided a clear image of rat testicular structure and reflected the level of oxygen metabolism in the testes.
Conclusion
2
PAT/MSOT can be used to detect the structural and functional changes in the testis caused by varicocele. PAT/MSOT is a novel,simple,and safe method for non-invasive evaluation of testes.
