海南鳽部分血液生理生化指标

Some Biochemical and Physiological Indices in Blood of Gorsachius magnificus

应用血球分析仪和全自动生化分析仪测定了海南鳽的7项血液生理指标和33项血清生化指标。结果显示:海南鳽像兀鹫一样具有大型的红细胞,与已报道的白鹭、池鹭、夜鹭、彩鹳、石鸡等几种鸟类相比,其平均红细胞体积(MCV)和平均红细胞血红蛋白含量(MCH)较高,红细胞计数(RBC)、红细胞压积(HCT)和血红蛋白浓度(HGB)均较低;尿素(Urea)含量较高。有关红细胞的生理指标揭示了海南鳽的血液携氧能力较低。生化指标与其他鸟类的差异可能是由物种不同所致。

Seven physiological and 33 biochemical indices of Gorsachius magnificus were determined by automatic biochemical analyzer and blood cell analyzer. The results showed that large erythrocytes were found in the avian Gorsachius magnificus, MCV were similar to that of the vulture Gyps africanus. G. magnificus had higher MCV and MCH, lower RBC, HCT and HGB, and higher urea concentration than those of other reported birds i. e. E. garzetta, A. bacchus, N. nycticorax, M. leucocephala, and A. chukar. The physiological indices of erythrocytes indicated that the blood of G. magnificus had a low oxygen-carrying capability. The differences between Gorsachius magnificus and other avian species in blood biochemical indices could be attributed to them being different species.
