    Notes: Abstract To assess testicular function in experimental varicocele rats, we used 31P magnetic resonance (MR) spectroscopy and compared MR spectroscopic parameters with flow cytometric DNA analysis. In vivo 31P MR spectroscopy and flow cytometric DNA analysis of testes were performed in 10 sham-operated and 9 induced varicocele rats. Although the testicular phosphomonoester (PM)/ATP ratio did not differ between sham-operated and induced varicocele rats, the phosphodiester (PD)/ATP ratio was significantly reduced and the inorganic phosphate (Pi)/ATP ratio was significantly increased in induced varicocele rats. There was no difference between the right and left sides. DNA flow cytometry showed a decrease in the percentage of haploid cells in induced varicocele rats, regardless of the side. This study indicates that in vivo 31P MR spectroscopy provides valuable information for assessment of testicular function.

    Notes: Summary Spinal cord atrophy takes on several different forms which correlate closely with specific clinical features. The majority of them, however, can be categorized into three distinct patterns, diffuse (transverse myelopathy), hemi-(Brown-Sequard syndrome), or anterior (anterior spinal artery syndrome) atrophy. Until recently, the differential diagnosis had been made solely on the neurological examination. We present three cases of spinal cord atrophy, one in each category. Spinal computed tomography with metrizamide appears to be a reliable supporting diagnostic method for spinal cord atrophy.
