摘要
目的为了让学生更好地了解各类型缺氧所具有的特征,本实验不仅需要对各类型缺氧导致的小鼠呼吸、皮肤黏膜以及血液的颜色变化进行观察,还需检测不同类型缺氧时小鼠血红蛋白性质的改变。方法将小鼠随机分为正常对照组、密闭容器组、一氧化碳组和亚硝酸钠组,使用血氧分析仪测定小鼠血液中不同类型血红蛋白的百分比含量。研究时间为2021年2月至2022年5月。结果与正常对照组相比,密闭容器组小鼠还原性血红蛋白明显增高,一氧化碳组小鼠碳氧血红蛋白明显增高,腹腔注射亚硝酸钠组小鼠高铁血红蛋白明显增高,而4组小鼠总血红蛋白比较差异无统计学意义(P>0.05)。结论本研究通过观察不同原因复制的缺氧类型中血红蛋白性质的变化,从而明确缺氧模型实验中观察到的现象之间是否存在定量关系,提高实验的准确性。
Objective In order to enhance students'understanding of the characteristics of various types of hypoxia,the experiment not only needs to observe the changes in mouse respiration,skin mucosa and blood color caused by different types of hypoxia,but also needs to detect the changes in the properties of hemoglobin in mice under different types of hypoxia.Methods Mice were randomly divided into normal control group,airtight container group,carbon monoxide group,and sodium nitrite group.A blood oxygen analyzer was used to determine the percentage content of different types of hemoglobin in mouse blood.The study was conducted from February 2021 to May 2022.Results Compared with the normal control group,mice in the airtight container group showed a significant increase in reduced hemoglobin,carbon monoxide group mice exhibited a significant increase in carboxyhemoglobin,and mice in the sodium nitrite group injected intraperitoneally showed a significant increase in high iron hemoglobin.However,the total hemoglobin difference among the four groups of mice was not statistically significant(P>0.05).Conclusion This study clarifies the quantitative relationship between observed phenomena in hypoxia model experiments by examining changes in hemoglobin properties in different types of experimentally induced hypoxia.This contributes to the improved accuracy of experimental observations.
