ABSTRACT
Objective To study the change of erythrocyte indices and serum iron in hyperthyroidism rats .Methods SD female rats were randomly divided into hyperthyroidism group and control group .Hyperthyroidism rats were induced by intragastric ad‐ministration of Euthyrox (Levothyroxine) and their blood and serum were obtained after administration of 1-8 weeks ,respective‐ly .And the control rats were given normal saline .Levels of T3 ,T4 and TSH were determined by a radioimmunoassay .Erythrocyte index were measured by automatic blood cell analyzer .Serum iron concentration and total iron binding capacity were determined by chromatometry .Results The concentration of serum T3 and T4 increased in hyperthyroidism rats ,whereas the TSH decreased . RBC was higher in hyperthyroidism rats at 2-8 weeks compared with the control rats (P<0 .05) .HCT was higher in hyperthy‐roidism rats at 1-8 weeks compared with the control rats (P<0 .01) .MCV was lower in hyperthyroidism rats at 2-8 weeks com‐pared with the control rats (P<0 .05) .MCHC was lower in hyperthyroidism rats at 1 -8 weeks compared with the control rats (P<0 .01) .RDW SD and RDW CV was higher hyperthyroidism rats at 1-2 weeks compared with the control rats(P<0 .01) .Ser‐um iron concentration and total iron binding capacity increased in hyperthyroidism rats at 4 -8 weeks compared with the control rats(P<0 .01) .Conclusion The hyperthyroidism rats in the present study is absent significant manifestation of anemia ,whereas the hypochromic changes of erythrocyte is significant .Serum iron concentration and total iron binding capacity increase in hyperthy‐roidism rats ,which demonstrate the iron utilization disorder .
