Abstract:
Objective To observe the effects of short-term withdrawal of thyroxine on lipid level and the protective effect of atorvastatin.Methods The study included 60 rabbits which were randomly divided into treatment experiment group 1 (near-total thyroidectomy + 131 I ablative therapy),treatment experiment group 2 (near-total thyroidectomy + 131I ablative therapy + Atorvastatin intervention) and control group(sham thyroidectomy).Compared the thyroid functions and lipid levels among different groups at the points of before surgery.three weeks after surgery and five weeks after surgery.Results (1) Compared to before surgery,the thyroid function at the points of three weeks and five weeks after surgery were obvious reduced both in treatment group.(2) The leves of TG,TC,LDL-C in EG1 were increased gradually with the extension of time after surgery.Compared with the point of before surgery,the level of HDL-C at the point of five weeks after surgery was significantly declined in EG1.Compared with the point of before surgery,the level of TG at the ponts of three weeks and five weeks after surgery was significantly declined in EG2.Compared with the point of before surgery,the level of LDL-C at the point of three weeks after surgery was significantly declined in EG2.Conclusions (1) Short-term hypothyroidism can increase the levels of TG,TC,LDL-C in plasma.(2) Atorvastatin can maintain the stability of blood lipids during Short-term hypothyroidism.
