ABSTRACT
In order to explore the effects of testicular infection of murine cytomegalovirus (MCMV) on mature sperm viability at different periods following MCMV inoculation in mice, 91 BALB/c mice without MCMV infection were randomly divided into two groups: an experimental group (n = 56) and a control group (n = 35). The mice in the experimental group were treated by inoculating MCMV intratesticularly, while those in the controlled group were directly inoculated with DMEM without MCMV. The mice in both groups were sacrificed separately on the day 1, 1. 5, 2, 4, 6, 9 and 14 post-inoculation (D1) 1. 5, 2, 4, 6, 9 and 14 PI). The MCMV M83 mRNA gene was detected in the testis by in situ hybridization (ISH) with MCMV late-mRNA probe labeled with digoxin. Sperm viability of mature sperm in the epididymis cauda was measured. The results demonstrated the positive signal of ISH of MCMV was found mainly in the cytoplasm of the testicular interstitial cells and spermatogenic cells in the experimental group. Compared with that in the controlled group, the sperm viability in the experimental group was decreased significantly on D1 PI and D1.5 PI (P 0.05). This suggested that sperm viability in mice might be descended significantly shortly after MCMV infection and might return to normal with time, indicating that MCMV acute infection might temporarily degrade sperm quality and influence procreation transiently.

This is a case report a of hepatitis C-positive 43-year-old male who presented with small vessel involvement resulting in infarction of the testis, kidney and fingers in addition to multiple and painful aneurysms of arteries. The diagnosis, features and management of the patient are discussed briefly
