Abstract:
Objective To evaluate the change of serum creatinine (Scr) before and after administration of contrast agent in different dose,to observe the difference of dog's kidney tissue with electron microscopy and investigate the effect of contrast agent on renal function.Methods Twelve dogs were divided into four groups randomly:the control group,the low dose group,the moderate dose group and high dose group.After the administration of different doses of iodine contrast agent at the same rate,the changes of Scr and microscopic structure were compared before administration and 48 hours later.Results The differences of Scr before and 48 hours after administration were (4.6±1.6) μmol/L,(6.7±2.5) μmol/L,(6.9±4.5) μmol/L,(5.1± 1.9) μmol/L for control group,low dose group,moderate dose group and high dose group,respectively.There was no statistically significant difference among the groups (P ＞0.05).In high dose group,the mitochondria of tubular epithelial cells were swelling and obvious vacuoles were observed.Only a small amount of vacuoles existed in the renal tubular epithelial cells in low dose group.Conclusion Compared with the moderate and high dose group,the low-dose iodine contrast agent have less damage to the kidney cells of the dogs.
