SUMMARY In rats in which arthritis had been induced by injections of formalin, removal of the thymus led to slight aggravation of the disease. Cortisone, which prevented or arrested the arthritis in intact rats, produced serious aggravation of the condition in thymectomized animals.

This article reviews the embryology, physiology, and pathophysiology of the thymus. The anatomy of this lymphoid organ, the significance of the presence or absence of the thymus radiographically, and the role of the thymus in immunity are also reviewed. Finally, the pathologic presentation of thymic hypoplasia (DiGeorge syndrome) is discussed.

Endocrinology, 1981
Tritiated dihydrotestosterone ([3H]DHT) binds with high affinity to a single class of limited capacity sites in cytoplasmic preparations from rat and mouse thymus glands. The affinity of these bindings sites for [3H]DHT (Kd at 4 C, 1 nM) and their specificity [methyltrienolone (R1881) greater than DHT greater than testosterone much greater than ...

The continuous production of T lymphocytes requires that hematopoietic progenitors developing in the bone marrow migrate to the thymus. Rare progenitors egress from the bone marrow into the circulation, then traffic via the blood to the thymus. It is now evident that thymic settling is tightly regulated by selectin ligands, chemokine receptors, and ...

Tuberculosis is increasing in prevalence in North America, mainly due to HIV infection. We describe an unusual case of TB of the thymus in a HIV sero-negative Filipino immigrant who preoperatively was thought to have a thymoma. We describe the clinical, radiologic and pathologic findings and review the literature on TB of the thymus.

W15 Limiting MRI to the area of interest to shorten image acquisition time is essential. A long image acquisition makes successful breath-holding difficult, with resultant motion artifact significantly compromising image evaluation. Hyperventilating the patient before each breath-hold can be helpful. Oxygen administration has been shown to be even more

Thymic neoplasms are a common cause of an anterior mediastinal mass and may be benign or malignant. Thymic cysts are congenital or acquired and may be associated with a thymic malignancy. True thymic hyperplasia and thymic lymphoid hyperplasia may enlarge the thymus and simulate a neoplasm.

Immunology Today, 1984
The thymus has fascinated immunologists since the discovery that it influenced the maturation of T lymphocytes. However, only within the past five years have investigations of the thymus progressed beyond descriptive histology or functional studies performed at the population level.

Chest Surgery Clinics of North America, 2001
Technologic advances in imaging, particularly CT and MR imaging, have revolutionized the ability to noninvasively image the thymus. Increasing knowledge of the normal and pathologic states of the thymus has been accompanied by an increasing ability to depict morphologic alterations in this gland with fine spatial resolution and can even provide ...

Proper development of the thymus is critical for an individual to acquire full immune capability. A full complement of the components that participate in thymic development, interacting with each other at the correct time, is required for maturation.
