摘要
目的 :探求肝郁气滞阴茎海绵体组织中Ⅴ型磷酸二酯酶 (PDE5 )活性及疏肝理气活血中药对其影响。 方法 :采用与人类精神性应激十分相似的非损伤性应激刺激法 ,制造肝郁气滞型SD大鼠动物模型 4 0只 ,随机法将大鼠分为 :空白组 ;肝郁证造模组 (简称模型组 ) ;萎康凝胶高剂量给药组 (高剂量组 )和低剂量给药组 (低剂量组 ) 4组 ,每组 10只。以免疫组化与计算机图像分析技术测定海绵体组织中PDE5活性。 结果 :高剂量组阴茎海绵体组织中PDE5活性与模型组差异有显著性 (P <0 .0 1)。 结论 :肝郁气滞可导致阴茎海绵体组织中PDE5活性增强 。
Objectives: To study the PDE5 activity in corpora cavernosa of the Ganyu Qizhi model penis and the efffect of the Chinese herbal medicine Shugan Liqi Huoxue (SLH) ointment on it. Methods: Non-injury stress stimulus method similar to human spirit stress was used to extablish the Ganyu Qizhi animal(rat) model, and the PDE5 activity in corpora cavernosa of the rat penis was measured by the method of immunohistochemistry and computer image analysis. Results: The PDE5 activity in corpora cavernosa of the high-dosage SLH group was significantly different from that of the model group (P< 0.01). Conculsion: Ganyu Qizhi may increase the PDE5 activity in corpora cavernosa of the penis while SLH can reduce such activity.
