    Abstract:
    OBJECTIVE: To study the relationships of experimental varicocele to the apoptosis of epididymis epithelium and changes of the contents of alpha-1,4-glucosidase and sialic acid from the unilateral epididymis in adolescent rats, and to investigate the effects of varicocele on the unilateral epididymis epithelium. METHODS: Experimental left varicocele models of 16 adult male Sprague-Dawley rats were obtained by partial ligation of the left renal vein. The epididymides were collected for detecting the apoptosis of epididymis epithelium and the contents of alpha-1,4-glucosidase and sialic acid by using spectrophotometry. RESULTS: Seven days after the establishment of the left varicocele model, the index of the apoptosis of the left epididymis epithelium was significantly higher (P < 0.001) and the contents of alpha-1,4-glucosidase and sialic acid significantly lower (P < 0.05, P < 0.005) in the experimental group than in the control. CONCLUSION: The results suggest that unilateral varicocele may increase the apoptosis of epididymis epithelium and the contents of alpha-1,4-glucosidase and sialic acid and subsequently affect the synthesizing and secretory function of the epididymis.
