Acupuncture treatment on postoperative urinary retention keeps developing and innovating. And it is held to have better effect when compare with western medicine.

Effect of ornidazole on sperm in rats and its mechanism of action / 中华男科学杂志

<p><b>OBJECTIVE</b>To explore the reductive effect of ornidazole on sperm motility in rats and its mechanism of action.</p><p><b>METHODS</b>Twenty rats were randomly divided into three groups, a low dosage group (LD group, n = 5), a high dosage group (HD group, n = 8) and a normal control group (n = 7). Ornidazole (200 mg/kg, 400 mg/kg) was given to the LD and HD groups, and 0.5% carboxymethylcellulose sodium (CMC) administered to the normal control, all for 20 consecutive days. Immediately after, sperm density, motility and the morphological changes of the testis and epidiclymis were measured, and the concentrations of lactate dehydrogenase (LDH), alpha-glycosidase, malondialdehyde (MDA) and fructose in the testis and epididymis tissues were monitored.</p><p><b>RESULTS</b>Compared with the normal control, there were no obvious changes in sperm density (P > 0.05), but a significant decrease in sperm motility in the LD and HD groups (P < 0.01), and the concentration of LDH obviously declined (P < 0.01) while that of MDA distinctly increased in the HD group (P < 0.05).</p><p><b>CONCLUSION</b>Spermatogenic cells could be damaged by the increase of inhibiting MDA, while sperm motility could be decreased by inhibiting energetic transferase or non-protein substance in the epididymis. This might be one of the mechanisms of ornidazole on weak sperm models in rats.</p>
