The interaction of the thyroid gland, pineal gland and immune system in chicken.

چکیده
The interaction of immunological system, thyroid and pineal gland was studied in 5-week old males of Gallus domesticus. Several morphometrical parameters in pineal and thyroid glands were measured after bird immunization with human red blood cells and/or treatment with melatonin or seduxen, melatonin receptor blocker. The peak of the thyroid activity was found on Day 7 after immunization. The immune system appears to directly activate the thyroid gland only in the presence of certain level of melatonin. We suggest that the melatonin mechanism of action includes the enhancement of thyroid gland sensitivity to immune factors. Seduxen prevented the stimulatory influence of the immune system on the thyroid gland.

Background and Aim: Intracranial physiologic calcification is not accompanied by any evidence of disease and has no demonstrable pathological cause. It is often due to calcium deposition in the blood vessels of different structures of the brain. Computed tomography (CT) is the most sensitive means of detection of for this calcification. The aim of this study was the assessment of the intracrani...
متن کاملEvaluation of Thyroid Gland Irradiation in Women with Breast Cancer during Radiotherapy with different Radiation Energies at Supraclavicular Region
Introduction: During treatment of breast cancer, Radiotherapy to the Supraclavicular fossa region results in absorption of radiation by the thyroid gland and consequently leads to hypothyroidism in 40% of patients. The aim of this study was to compare thyroid gland radiation absorption during radiotherapy with different anterior-posterior beam radiation of 6-15 and 15-15 MV pho...

Living organisms have multiple biological rhythms. Some of these rhythms are endogenous and some are under the influence of light and dati cydes during 24-hours. Nowadays periodic changes in melatonin secretion from pineal gland and changes in N-acetyl transferase (NAT) activity which influence the melatonin secretion rate has been acknowledged as a basic rhythm. In this study NAT activity in p...
متن کاملComparison of Absorbed Fraction of Gamma and Beta Rays of I-124 and I-131radio-Isotopes in Thyroid Gland with Monte Carlo Simulation
I131 is a famous radio-iodine isotope in use for diagnosis and treatment of hyper functioning and cancerous thyroid gland. It is a nuclear reactor product; however nuclear reactor may be unavailable in some areas. Replacement by I-124 may be possible, another iodine isotope producible by cyclotron; a system more available than reactor. Here absorbed fraction of Gamma and Beta rays of...
