The thymus gland in the elderly, emaciated, dissecting-room subject is inconspicuous and, indeed, often difficult to make out. In younger subjects, who have not. died after a wasting disease, it is quite a conspicuous object, relatively greatest at birth, and absolutely at puberty. It is a flattish, bilobed, glandular mass lying in the anterior mediastinum and extending from the isthmus of the ...

Previous experimental work concerning enlargement of the thymus has dealt mainly with the regeneration which follows partial or subtotal removal, or with the regeneration which follows transplantation. We planned our experiments to obtain evidence of uncomplicated hypertrophy by removing one lobe and studying the enlargement of the remaining lobe. Our results clearly indicate that such hypertro...

Inferior thyroid artery is one of the main arteries supplying thyroid gland and laryngeal muscles. It also supplies pharynx, esophagus, trachea and thymus. It emerges from the thyrocervical trunk of the subclavian artery at the level of C6 vertebra. Then, it rapidly curves inferomedially, crossing the bundle of common carotid artery, internal jugular vein and vagus nerve. Further, it continues ...

OBJECTIVE To evaluate frequency, anatomic presentation, and quantities of supernumerary parathyroids glands in patients with primary hyperparathyroidism (HPT1) associated with multiple endocrine neoplasia type 1 (MEN1), as well as the importance of thymectomy, and the benefits of localizing examinations for those glands. METHODS Forty-one patients with hyperparathyroidism associated with MEN1...

I t has been demonstrated by a number of workers that the active principle of the thyroid gland in the causation of amphibian metamorphosis is iodine. Recently Swingle 1 has obtained definite proof that inorganic iodine when fed to larvm of Salientia induces metamorphosis in a short time after the be#nning of the feeding. On the other hand, it has been shown by the writer 2 that the retarding i...

SMALL lobules of aberrant thymus are not infrequently found in the neck, often within the thyroid gland, possibly present in up to 20% of humans (Goldstein and Mackay, 1969; Gilmour, 1941). However, ectopic thymic tissue of size sufficient to produce a palpable swelling of the neck is uncommon. In a review of the forty-six such cases recorded in the English literature, Hinds et al. (1970) found...
