Objective: The current study evaluates the effect of metformin (MET) and /or alpha lipoic acid (ALA) on hypothyroidism and its adverse effects on the cardiac, renal, and, hepatic functions in rats.
Materials And Methods: Rats were divided into five groups: control, rat model of hypothyroidism induced by propylthiouracil (PTU), rat model of hypothyroidism treated with MET, rat model of hypothyroidism treated with ALA, and rat model of hypothyroidism treated with MET and ALA. At the end of the experiment, body weight gain was determined and the blood samples were collected from orbital plexus to measure the serum levels of thyroxine (T4), triiodothyronine (T3) and thyroid stimulating hormone (TSH) by ELISA, glucose level, the activities of lactate dehydrogenase (LDH), creatine kinase MB (CK-MB), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP), and the levels of urea and creatinine spectrophotometrically.
Objective: The present study evaluates the neuroprotective effect of α-lipoic acid (ALA) and/or metformin (MET) on the behavioral and neurochemical changes induced by hypothyroidism.
Methods: Rats were divided into control, rat model of hypothyroidism induced by propylthiouracil, and rat model of hypothyroidism treated with ALA, MET, or their combination.
Results: Behaviorally, hypothyroid rats revealed impaired memory and reduced motor activity as indicated from the novel object recognition test and open-field test, respectively.
