摘要

为研究急性短期高温环境下机体营养物质代谢发生显著变化时犬血液学相关指标的变化规律，本试验采用人工模拟高温环境的方法，分别测定了试验犬（n=6）在（35±1）℃下持续0、3、8、16 h及自然降温16 h后的血常规、血液流变学及血清生化指标。结果显示：与试验开始前相比，急性短期高温环境下犬各试验时间点粒细胞计数、粒细胞百分比、红细胞变形指数和红细胞电泳指数均显著增加（P<0.05），血红蛋白浓度、淋巴细胞百分比和单核细胞百分比均显著降低（P<0.05），红细胞计数、红细胞压积、红细胞分布宽度、血小板压积、血小板分布宽度、平均血小板体积、红细胞聚集指数以及血清谷丙转氨酶活性、直/总胆红素值无显著变化（P>0.05）。结果表明，急性短期高温环境能显著改变犬血液学部分指标，揭示临床上可通过改善血液质量的方法缓解急性短期高温环境对犬造成的危害。

Abstract

This study was performed to explore the change rules of hematological related indexes in canine exposed by acute short-term high-temperature environment which significantly changes the body's metabolism of nutrients. In this experiment, the method of artificial simulated high-temperature environment was used, and the blood routine, hemorheological and serum biochemical indexes of trial canine (n=6) which were reared at (35±1)℃ for 0, 3, 8, 16 hours and the resulting process of natural cooling for 16 hours, respectively. The results showed as follows:when compared with the starting of experiment, the granulocyte count, granulocyte percentage, red cell deformation index and red cell electrophoresis index were significantly increased in canine exposed by acute short-term high-temperature environment at 3, 8, 16 hours and the resulting process of natural cooling for 16 hours (P<0.05); however, the hemoglobin concentration, lymphocyte percentage and monocyte percentage were significantly decreased (P<0.05). At the same time, there were no significant differences in red blood cell count, hematocrit, red blood cell distribution width, thrombocytocrit, mean platelet volume, platelet distribution width, red cell assembling index, and serum alanine aminotransferase activity and direct/total bilirubin value (P>0.05). These results show that acute short-term high-temperature environment can significantly change the some hematological indexes, and suggest that some methods improving the blood quality clinically may alleviate the acute short-term high-temperature environment hazards of canine.

Key words： canine; high-temperature; blood routine indexes; hemorheological indexes; serum biochemical indexes
