RESUMO
Objectives: Thyroid hormones regulate all metabolic activities; therefore, it is not amazing that hepatic; renal dysfunctions and lipid alterations are commonly detected in patients with thyroid disorders. This study estimated some biochemical changes in post pubertal hyperthyroid and hypothyroid mice and their impacts on liver and kidney functions and also on changes in the lipid pattern. In addition, the ameliorating role of Costus root extract supplementation was examined. Material and Methods: A total of 60 male Swiss albino mice were randomly divided into 5 groups; control, control with costus extract, hypo- and hyper-thyroids post-treated with costus root extract. Results: Present results revealed that, a significant increase in serum thyrotropin (TSH), alanine transaminase (ALT) and aspartate transaminase (AST), alkaline phosphatase (ALP), creatinine, urea, potassium, chloride, cholesterol and triglycerides levels in hypothyroid mice compared to control. On the other hand; a significant decrease in serumthyroxine (T4), tri‐iodothyronine (T3), albumin, total protein and calcium ions levels in hypothyroid mice compared to control. In contrast to hypothyroidism, a significant increase in serum T3, ALT, AST, ALP, creatinine, urea, sodium, potassium, chloride and total proteins levels in hyperthyroid mice compared to control. On the other hand; a significant decrease in serum TSH, T4, albumin, calcium ions cholesterol and triglycerides levels in hyperthyroid mice compared to control. Treatments of mice with Costus root extract in both hypo- and hyperthyroidism modulates the measured serum parameters. Conclusions: Our results could propose that the extract of Costus roots can be used as an adjuvant co-therapy in hypo- and hyperthyroidism syndromes with propylthiouracil and Eltroxin replacement therapy, respectively
