Assessment of the impacts of 830 nm Low Power Laser on Triiodothyronine (T3), Thyroxine (T4) and the Thyroid Stimulating Hormone (TSH) in the Rabbits
Journal Title: Journal of Medical Science And clinical Research - Year 2014, Vol 2, Issue 11
Abstract
This study has designed to research whether there an impact on the thyroid hormone in female rabbits irradiated by low power laser therapy (LPLT) in the thyroid gland region. Thirty female rabbits utilized in this investigation. Ten rabbits used for inspecting the thyroid gland location and dissected to make certain that low power laser source shall be directed to this gland. Twenty female rabbits divided into two equal groups: 10 used as control and the others have exposed to LPLT for three sequential days for five minutes on either side. LPLT irradiation procedures consisted of an infrared diode laser emitting at 830 nm in continuous mode, point manner on the thyroid gland role. Blood collected for secretion assay from the ear vein at 1st, 4th, 7th, 10th, 13th, 16th, 19th, 22th, 25th and 30th days after the last treatment of LPLT. The results discovered a gradual decrease in Triiodothyronine (T3) and Tetraiodothyronine (T4) levels. A concomitant increase in Thyroid-Stimulating Hormone (TSH) level, then the normalization of hormone level has taken place to be normal after thirty days. It has concluded that LPLT of the thyroid gland can produce an effect on the thyroid hormone levels. A supplementary work is required on this topic to examine the specific role of LPLT on the glands.
