The effect of pentoxifylline on fresh and frozen-thawed dog spermatozoa was evaluated. In Expt 1, 0.0036 mol l-1 or 0.0072 mol l-1 pentoxifylline was added to fresh dog spermatozoa. Semen was incubated at 25 degrees C or 39 degrees C. In Expt 2, pentoxifylline was added either before freezing or in the process of thawing at a final concentration of 0.0072 mol l-1. Addition of pentoxifylline significantly increased the percentage of progressively motile spermatozoa in fresh semen. The most beneficial effect of pentoxifylline on frozen-thawed semen was observed (P < 0.001) when it was added to semen in the process of thawing.
评估了己酮可可碱对新鲜和冻融犬精子的影响。在实验1中，将0.0036 mol l-1或0.0072 mol l-1的己酮可可碱添加到新鲜犬精子中。精液在25℃或39℃下孵育。在实验2中，在冷冻前或解冻过程中添加己酮可可碱，终浓度为0.0072 mol l-1。添加己酮可可碱显著增加了新鲜精液中进行性运动精子的百分比。当在解冻过程中将己酮可可碱添加到精液中时，观察到其对冻融精液最有益的效果（P < 0.001）。
