目的：从血液流变学角度进一步探讨各类阳萎的发病机制。方法：对43例各类阳萎患者（阳萎组）和20例正常对照者（对照组）进行血液流变学指标对照研究，其中包括全血低切粘度（10s-1）、全血高切粘度（100s-1）、血浆粘度（ηp）、红细胞压积（HCT）、血沉（ESR）、红细胞聚集指数（CE）、红细胞刚性指数（IR）、全血还原粘度（ηw）、血沉方程K值。结果：阳萎组10s-1、ηp、CE、K值、ηw明显高于对照组（P＜0．05），其中内分泌性阳萎10s-1、IR明显高于对照组（P＜0．05），心理性阳萎10s-1、HCT明显高于对照组（P＜0．05），动脉性和静脉性阳萎与对照组间无显著性差异（P＞0．05）。结论：阳萎组血液呈高粘滞性，心理性和内分泌性阳萎患者血液粘滞性升高是阳萎血液粘稠度升高的主要原因，HCT升高是心理性阳萎血液粘滞性升高的主要因素，而IR升高是内分泌性阳萎血液粘滞性升高的主要因素。
Objective: To further explore the pathogenesis of various types of impotence from the perspective of hemorheology. Methods: A total of 43 cases of impotence patients (impotence group) and 20 normal controls (control group) were studied on hemorheology indexes, including low blood viscosity (10s-1), whole blood high Shear viscosity (100s-1), plasma viscosity (ηp), hematocrit (HCT), erythrocyte sedimentation rate (ESR), erythrocyte aggregation index (CE), erythrocyte rigidity index (IR), whole blood reducing viscosity (ηw) K value. Results: The values of 10s-1, ηp, CE, K and ηw in the impotence group were significantly higher than those in the control group (P <0.05). The 10s-1 and IR of endocrine impotence were significantly higher than those of the control group. 05), psychological impotence 10s-1, HCT was significantly higher than the control group (P <0.05), arterial and venous impotence and the control group no significant difference (P> 0.05). CONCLUSION: The blood in the impotence group showed hyperviscosity. The increase of blood viscosity in patients with psychic and endocrine impotence was the main reason for the impaired blood viscosity. Impaired HCT was the cause of psychological impotence and blood stasis Sexual increase in the main factors, and IR increased endocrine impotence blood viscosity is the main factor.
