radiological evaluation of the common sage (ziziphora tenuior) extract effects in myna hypothyroidism

The present study aimed to investigate the radiological effects of common sage (ziziphora tenuior) extract on hypothyroidism in myna (acridotheres tristis). this descriptive-cross sectional study involved 20 male myna with an average age of 11.00 ± 9.00 months and a mean weight of 241.00 ± 42.00 g. the birds were randomly and equally divided into five groups including a negative control group, a positive control group, and three treatment groups receiving alcoholic extract of common sage at 1.00, 2.00, and 3.00% concentrations. the alcoholic extract of common sage was administered to the three treatment groups for 40 days. propylthiouracil was used to induce hypothyroidism. after induction and onset of hypothyroidism symptoms, radiographs in lateral and ventrodorsal positions were obtained from all myna on days 0 and 45. the results of this study showed that following the induction of hypothyroidism and the development of osteoporosis in mynas, thin and shell cortical signs were observed in the radius, ulna, tibia, and fibula bones. with the initiation of treatment with alcoholic extract of common sage, the signs of osteoporosis were reduced in the study groups, and this reduction was significant in the treatment group received 3% of the extract from this plant. the findings of this study suggest that alcoholic extract of common sage can stimulate the thyroid gland and increase serum thyroid hormone levels in mynas.
