The effect of thyroid dysfunction and treatment on fat tissue adiponectin levels in rats

摘要

Adipose tissue is a hormonal active system that produces and releases leptin.adiponectin and resistin.Seen from this aspect,it may be thought that adiponectin may interact with the thyroid axis.Thyroid function disturbance led to changes on the body weight,muscle volume and adipose tissue.Experimental findings show that adiponectin and thyroid hormones have biological intemctin with each other.However,various results have been reported a relationship between thyroid hormones and adiponection levels.The aim of the present study was to determine adipose tissue adiponectin levels in rats with thyroid dysfunction and after treatment.Study was performed on 40 Sprague-Dawley male rats.Groups were designed as 1-control.2-hypothyroidism(Hypo).3-hypothyroidism + Thyroxine.4-hyperlhyroidism(Hyper).5-hyperlhyroidism + PTU.At the end of 3 weeks experimental period,adipose tissues of rats were analyed for adiponection by Elisa.Experimental hypothyroidism reduced adipose tissue adiponectin levels,but hyperthyrodism increased.Treatment of hypothyroidism and hyperthyroidism corrected disrupted adiponectin levels to control.The results of the present study show that experimental thyroid dysfunction has affected adipose tissue adiponection levels in rats.
