To determine the effect of ART on the thyroid function after hypothyroidism in rats, body weight, food intake per day, core body temperature, glucose level, serum thyroid stimulating hormone (TSH), tri-iodothyronine (T3) and L-thyroxine (T4) levels, and ghrelin and glucagon-like peptide-1 (GLP-1) secretion were calculated. Here, GCG is linked to hypothyroidism.
