【摘要】 目的:随着电能在生产和生活中的广泛应用,电烧伤发病率呈逐年上升趋势,已成为危害人类健康的主要创伤之一。高压电烧伤是电烧伤的主要组成部分,其病理变化复杂,对机体的影响广泛,具有较高的死亡率和致残率。因而,高压电烧伤的基础和临床研究受到医学界重视。高压电对机体的损伤机制涉及“电热效应”、“容积导电”、“真性电损伤”、“微循环障碍”等,其中微循环障碍在高压电烧伤后机体的进一步损害过程中起重要作用。同时高压电烧伤所致的微循环障碍大部分具有可逆性,经过正确治疗,可使微循环障碍解除或减轻,以达到保护受伤组织、器官和挽救生命的目的。白细胞流变行为异常是导致微循环障碍的重要原因之一。以往对高压电烧伤微循环的研究主要集中在微血管形态和微血流动力学上,并发现了高压电对机体外周组织和脏器微循环均有不同程度的影响,也发现了在微静脉内有白细胞增多的现象,但对白细胞流变行为变化及相关机制尚未进行深入和系统的研究。因此,本研究通过复制大鼠经颅高压电烧伤模型,以肠系膜为微循环观察窗,研究动物活体状态下白细胞在微静脉内的流变行为,检测电伤后P-选择素、E-选择素、L-选择素、可溶性细胞间黏附分子-1(sICAM-1)及CD11b/CD18的变化,并采用乌斯他丁及己酮可可碱治疗,探讨白细胞流变行为异常在高压电烧伤微循环障碍中的作用及相关机制,并为高压电烧伤微循环障碍的治疗提供实验依据。方法:成年雄性SD大鼠369只。随机分为对照1组、电伤1组、治疗1组(前三组),每组各15只,用于电伤后白细胞流变行为的研究;对照2组、电伤2组、治疗2组(中三组),每组60只,每组分6个时相组,每个时相组10只,用于研究电伤后选择素家族对白细胞流变行为的影响;对照3组、电伤3组、治疗3组(后三组),每组48只,每组分6个时相组,每个时相组8只,用于研究电伤后免疫球蛋白超家族的CD11b/CD18及血清sICAM-1对白细胞流变行为的影响。电伤三个组和治疗三个组均复制2kV经颅高压电烧伤大鼠模型;治疗1组和治疗3组采用乌斯他丁于电伤即刻一次性给药治疗,治疗2组采用己酮可可碱于电伤即刻一次性给药治疗;对照组采用只连线不通电的方法处理。观察时相分别为伤前15min、伤后5min、1h、2h、4h、8h。前三组使用微循环显微镜按时相观测肠系膜微静脉白细胞流变学变化,观察指标:滚动白细胞数(个/

【Abstract】 Objective: As the generally application of electrical in production and life, the incidence rate of electrical burn is increasing annually, and become one of the key heals that endanger people health. High voltage electrical burn, the main component of electrical burn, has high death rate and maim rate for its complex patholo gical variation. So, electrical burn basis and clinical study is being attached importance in medical area.The damage mechanism of electrical burn involves electric-hot, volume-electric conduct, actual electrical damage、micro-circulation obstruction and so on, among microcirculation plays an important part in further damage after high voltage electrical. At the same time, most microcirculation obstruction is reversible. Microcirculation obstruction could be relieved or abate to protect damaged tissues、organs and save lifes after correct treatment.Leucocytes rheological behavior change is an important cause of microcirculation obstruction. Former high-voltage burns microcirculation research focuses on microvascular form and micro hemodynamics, people found that high voltage electrical affect peripheral tissues and visceral microcirculation in different extent, and Leucocytes multiply in micro-veins. but didn’t study Leucocytes rheological behavior and related mechanism deeply and systematically yet. This experiment duplicates rats transcranial high voltage electrical burn models through the big, observes mesenteric micro-vessel, studys Leucocytes rheological behavior in micro-veins when the animals is live, and detects the change of P-selectin、E-selectin、L-selectin、sICAM-1 and CD11b/CD18.

The third step to study the effect of CD11b/CD18 and sICAM-1 on rheology characters of leukocytes after HEB, 144 SD rats were randomly divided into three groups, consisting of control three group, electricical burns three group and treatment three group, 48 for each, every group was falled into six phases to study, 8 rats for each phase.

The CD11b/CD18 in the treatment group 3 after HEB were significantly hegher than before the burn 15min.The CD11b/CD18 of three groups at 15min before burn intercomparison (P﹥0.05). The CD11b/CD18 of electrical burn group 3 and treatment group 3 in each phase were hegher than the control group 3(P﹤0.05). The treatment group 3 each phase were less than the electrical burn group 3 (P﹤0.05).12 The adhesion leukocytes in aboral three groups and center three groups have same trend.13 The skin perfusion in aboral three groups and center three groups have same trend.Conclusion:1 High-voltage electrical burns can cause leucocyte rheological abnormity change : count increase, rolling speed decrease, adhesion leukocytes increase, TLECT value extend.2 Ulinastatin can reduce abnormity leucocyte rheological that were caused by high-voltage electrical.3 High-voltage electrical burns can increased selectin-P, and selectin-E, and selectin-L and adhesion leukocytes in mesentery venuel, decreased chest wall skin perfusion.4 Pentoxifylline can reduce selectin-P, and selectin-E, and selectin-L ,decrease adhesion leukocytes in mesentery venuel , increase chest wall skin perfusion.5 High-voltage electrical burns can increase sICAM-1, and CD11b/CD18, and adhesion leukocytes and decrease chest wall skin perfusion.6 Ulinastatin can decrease sICAM-1, and CD11b/CD18, and adhesion leukocytes and increase chest wall skin perfusion.7 High-voltage electrical burns can cause leucocyte rheological abnormity change, selectin-P, and selectin-E, and selectin-L, and sICAM-1, and CD11b/CD18 et al play an important role in leukocyte adhesion. Ulinastatin and Pentoxifylline can reduce leucocyte rheological abnormity change.
