5—羟色胺是肺循环血管活性物质,在其些非心源性肺水肿的发生过程中,可能起着一定的作用,为了观察呼吸道蒸气烧伤肺水肿发生机制中5—羟色胺的作用,本组实验用四川地区杂种狗经116℃蒸气灌气6秒造成典型肺水肿模型观察致伤后4小时内肺静脉血,全血—羟色胺含量,以及4小时后肺组织中5—羟色胺与5—羟吲哚醋酸含量的变化。初步探讨5—羟色胺是否参与肺水肿的发生。5—羟色胺与5—羟吲哚醋酸用萤光分光光度法测定。致伤组与对照组动左心室全血5—羟色胺含量见表一,致伤组与对照组动物在致伤4小时后活杀,肺组织中5—羟色胺与5—羟吲哚醋酸含量见表二。左心室全血5—羟色胺含量
Serotonin is a circulating pulmonary vasoactive substances in some of its non-cardiogenic pulmonary edema may play a role in the process, in order to observe the mechanism of respiratory steam burn pulmonary edema serotonin role in this group of experimental A typical model of pulmonary edema in hybrid dogs in Sichuan Province at 116 ℃ for 6 seconds was used to observe the pulmonary venous blood and serum total serotonin levels within 4 hours after injury and the levels of serotonin and 5-hydroxyindole acetic acid Changes in content. To investigate whether serotonin participate in the development of pulmonary edema. Serotonin and 5-oxindole acetic acid were measured by fluorescence spectrophotometry. Serum and serum 5-HT levels in the left ventricular blood of the injured group and the control group are shown in Table 1. The injured and control animals were killed 4 hours after the injury and the content of 5-hydroxytryptamine and 5-oxindole acetic acid in the lung tissue Table II. Left ventricular whole blood 5-HT content
