作者通过72只雄鼠的实验,证明肝素化可改善睾丸缺血耐受性,加用α-受体阻滞剂更可明显改善此耐受性。作者认为阻断睾丸血流前给予肝素可预防最细的睾丸小动脉血栓形成,使血流恢复后就能立即保证其血液循环而进行氧灌注和带走代谢产物,再加用α-受体阻滞剂则可阻碍血流恢复后继续发生的血管痉挛。作者已对16例幼童自体睾丸移植应用上述处理,睾丸缺血时间为20～90分钟,术前口服Dibenzyran0.5mg/kg,阻
The experiment of 72 male rats proved that heparin could improve testicular ischemic tolerance. Adding α-receptor blocker could obviously improve this tolerance. The authors suggest that blocking heparin before testicular blood flow may prevent thrombosis of testicular arterioles that are the smallest, allowing blood to circulate immediately after blood flow is restored for oxygen perfusion and metabolic products, plus alpha-receptors Blockers can then hinder the continued vasospasm after blood flow is restored. The authors have 16 cases of young children with autologous testicular transplantation application of the above treatment, testicular ischemia for 20 to 90 minutes, preoperative oral Dibenzyran 0.5mg / kg, resistance
