摘    要:
目的探讨急性高原缺氧条件下氰化钠中毒对大鼠脑组织能量代谢的影响。方法雄性sD大鼠,分为平原组和高原组。平原组动物在本地常规实验室内处理。高原组动物放置于模拟4000m海拔高度的低压舱内3d后开始实验。为大鼠腹腔注射氰化钠(NaCN)3.6mg/kg染毒,于0、0.5、1、2、4、6h6个时相点麻醉后断头取脑。以干湿质量法测定脑组织含水量,伊文思蓝法检测脑组织血管通透性,高效液相色谱(high performance liquid chromatography,HPLC)法测定大鼠脑纹状体和海马组织腺苷三磷酸(adenosine triphosphate,ATP)、腺苷二磷酸(adenosine diphosphate,ADP)和腺苷-磷酸(adenosine monophosphate,AMP)含量。结果与平原组比较,高原缺氧环境氰化钠中毒大鼠脑组织含水量增加,纹状体和海马组织ATP和ADP含量减少,AMP含量增加。结论高原缺氧可导致大鼠脑组织腺苷酸能量代谢障碍,缺氧条件下氰化钠中毒可进一步加重脑组织能量代谢障碍,同时脑水肿也进一步加重。

关 键 词:高原  低氧  氰化钠  腺什酸  海马  纹状体

Abstract:
Objective To investigate the effect of sodium cyanide(NaCN)intoxication on brain energy metabolism in rats under hypoxia.Methods Male SD rats were randomized equally into normal altitude group and high altitude hypoxia group.The animals in the high altitude hypoxia group were pre-exposed in a hypobaric chamber simulating 4 000 m above sea level for 3 d and were injected with 3.6 mg/kg NaCN intraperitoneally.The rats in the normal altitude group were treated in a routine laboratory in Chongqing(308 m above s...
Keywords:high altitude simulated 4 000 m  hypoxia  sodium cyanide  adenine nucleotide  hippocampus  corpus striatum
