    Abstract:
    OBJECTIVE: To observe the change of erythrocyte theology in rabbits with acute renal failure (ARF). METHODS: Thirty-eight healthy rabbits were randomly divided into control group (n = 8), model group (establishing ARF model via intramuscular injection 1% HgCl2, and divided into 12 h, 24 h, 48 h subgroups, all n = 10), the arterial blood sample was taken out through carotid artery at corresponding times after anesthetization with urethane, for detecting the indices of renal function and erythrocyte rheology. RESULTS: The levels of urea and creatinine in plasma of model rabbits at 12 h, 24 h and 48 h were higher than those of control group, and there was a rise trend along with the time extension. The erythrocytes electrophoresis time at 12 h of model group was higher, the electrophoresis rate and migration rate of erythrocytes were lower compared with those of control group; the erythrocytes electrophoresis time at 24 h of model group was lower and the electrophoresis rate and migration rate were higher compared with those of model group at 12 h; and there were no statistical differences in erythrocytes electrophoresis indices between model group at 48 h and other groups. Meanwhile, there was a rise trend in erythrocyte sedimentation rate (ESR), K value of equation and emendation along with the time extension of ARF, but these indices only at 48 h of model group was lower significantly than that of control group. There were no statistical differences in aggregation index and deformability index of erythrocytes among groups. CONCLUSION: During the process of ARF, the erythrocytes electrophoresis time lengthen and electrophoresis rate and migration rate decrease at early stage, and these indices gradually return to normal; the indices of ESR increase gradually.
