Therapeutic effect of Jinghuosu on oligospermia and asthenospermia / 中华男科学杂志

Objective@#To investigate the effects of the compound preparation Jinghuosu on oligospermia and asthenospermia.@*METHODS@#This multi-centered clinical study included 120 cases of mild to moderate idiopathic oligospermia or asthenospermia, all treated with oral Jinghuosu once a bag, bid, for 3 successive months. Before and at 1, 2 and 3 months after treatment, we detected sperm concentration, total sperm motility, progressive sperm motility and normal sperm morphology of each ejaculate, and recorded whether the patients had any adverse reactions.@*RESULTS@#After 3 months of treatment, all the patients showed obvious improvement in semen parameters, most significantly in sperm concentration, total sperm motility, and the percentages of progressive motile sperm and morphologically normal sperm (P <0.05). No significant adverse reactions were observed during the 3 months of medication.@*CONCLUSIONS@#Jinghuosu has a significant efficacy and no obvious adverse effect in the treatment of mild to moderate oligospermia and asthenospermia.

Nandeshi: a powerful inhibitor of human acrosin activity / 中华男科学杂志

<p><b>OBJECTIVE</b>To evaluate the inhibitory effect of Nandeshi, an acrosin inhibitor, on human acrosin activity.</p><p><b>METHODS</b>We collected sperm samples from 10 healthy fertile men and cultured them with Nandeshi at 30 degrees C for 5 minutes at the concentrations of 0. 100, 0.120, 0.144, 0.173, 0.207, 0.249, 0.299, 0.358 and 0.430 mmol/L, with the controls treated with a well-known acrosin inhibitor N-alpha-p-tosyl-L-lysine chloromethylketone (TLCK) at 150.0, 189.8, 213.6, 240.3, 270.3, 304.1 and 342.1 mmol/L. Then we determined the residual activity of human acrosin by improved Kennedy assay.</p><p><b>RESULTS</b>The residual activity of acrosin was negatively correlated with the Nandeshi concentration, and Nandeshi exhibited an inhibition rate about 800 times that of TLCK.</p><p><b>CONCLUSION</b>Nandeshi has a powerful inhibitory effect on human acrosin, and improved Kennedy assay is a simple, practical and highly sensitive technique for the detection of human acrosin activity.</p>
