Autoimmune thyroiditis (EAT) can be induced by immunizing mice against mouse thyroglobulin. A gene critical to the phenotypical expression of EAT was mapped to the H-2K locus by studying B6 mice and its mutant strain B6.H-2ba. To identify organs in which expression of the gene was decisive for the EAT phenotype, we transplanted thyroid or irradiated thymus glands into various strains of normal ...

Concentrations of actinomycin D-3H in tissues and organs of mice were measured at 30 min and other times up to 48 hr after injection (600 ~g/kg). Although this dose is sublethal for mice, it is known to damage cells of the intestinal epithelium, spleen, thymus, and the sensitive Ridgway osteogenic sarcoma (ROS). I t has little or no cytotoxic effects on mouse liver or the solid, transplantable ...

Ectopic parathyroid adenomas can be a cause of recurrent and refractory hyperparathyroidism. Majority are located in the neck region, however very few cases they within mediastinum. In such excision via cervical approach is not possible it becomes diagnostic as well surgical challenge. Excision thoracoscopic preferred this regard. Here we represent case ectopic adenoma embedded thymus gland whi...

The thymus is a gland originating from the epithelium, which forms in the third portion of the pharynx during the tissue matching that takes place in the sixth week of fetal life. In the eighth week of fetal life there is a migration of the thymus from the cervical region towards the caudal and medial region to its final location at the upper mediastinum. Failure of this migration will cause ab...

an abnormally large thymus gland in itself cannot be considered to be indicative of status thymicolymphaticus when no obvious cause of death is found at post mortem. On the other hand, Moncrieff (1938) has remarked that an enlarged thymus is not a common chance finding .in .the chests of infants who have been z-rayed for other conditions, of heart or lungs. Also a study of a number of healthy i...

Objectives The aim of this study was to investigate the effects of pinealectomy and melatonin treatment on the rat thymus gland characteristics, taking into consideration possible gender differences. Materials and methods Thirty adult Wistar rats of both sexes were divided into three groups. Group C and group PX served as control groups and included sham-pinealectomized and pinealectomized an...

ture of both thymus and thyroid. The discovery of the thyro-thymic lymphatic channels is not of recent date, but was the result of work done by Sir Astlv Cooper, who described them in 1832. Recently, Sir Arthur Keith has found in the museum of the Royal College of Surgeons, England, injection specimens of thyroid and thymus attributed to Sir Astly Cooper. In a ' Physiological essay 011 the thym...

The volatile constituents of the aerial parts of two samples of Thymus longicaulis C. Presl, collected in Campania and in Sicily, and two samples of Thymus pulegioides L. from the same regions, were extracted by hydrodistillation and analyzed. Considering the four oils together, seventy-eight different compounds were identified: 57 for Thymus longicaulis from Sicily (91.1% of the total oil), 40...

True massive thymic hyperplasia is a very rare entity, characterized by an increase in the size and weight of the thymus gland, without an apparent cause. Surgery has been required in patients with severe respiratory distress. We present an idiopathic true massive thymic hyperplasia in a 5-month-old boy.

Cod liver oil and Viosterol in therapeutic doses are antirachitic in the absence of the parathyroid gland, or of the thymus, or of both.
