The effect of a purified bovine thymus gland extract (Dr. Kurt Mulli, GmbH, Hamburg, West Germany) was studied in 12-week old male Wistar rats on the following: thyroid weights and morphology, T3-T4 serum levels, thyroid lactic dehydrogenase, ATP-ase, acid phosphatase, and non-specific esterase activities. Thymus extract was administered intramuscularly daily for 21 days at doses of 0.5, 1.0 an...
Individuals with no thymus rapidly die from opportunistic infections due to total failure of the immune system. Experience in cases of infection with the human immunodeficiency virus (HIV) known as AIDS clearly shows that the thymus gland and the thymus helper lymphocytes (T cells) dependent on it are destroyed in the course of the disease. This generally triggers a series of severe consequenti...
We recently have reported several studies concerning the marked stimulation of growth and regeneration that occurs in the thymus gland of rats, of any age, following double suprarenalectomy (1-3). We showed that, as the result of such a procedure, marked hyperplasia of the involuting thymus, with enlargement of the same, occurs with great constancy. In line with these studies, we undertook a se...
In the following article we have provided modern data on main stages of implementation, formation as well stabilization functional activity thymus fetus different fetal development. Thus, analyzed specific features gland’s location in case children, adolescents and adults. We described two organ’s ontogenesis. addition, histological implemetation, starting with 8th week embryonic development we...
Ectopic intrathyroidal thymic tissue can form a mass lesion within the thyroid gland and has rarely been reported in children. We report a case of intrathyroidal thymus accompanied by an intrathyroidal parathyroid gland in a 29-year-old woman who visited our hospital due to right neck mass diagnosed as metastatic papillary carcinoma by aspiration cytology in an outside hospital. She had a histo...
The thymus gland is a lymphoid tissue derived from III and IV pharyngeal pouches. It is the source of stem cells that migrate to other lymphoid organs and participate in immune reactions (Kent, 1978). The thymus gland is regarded immunologically as a primary or central lymphoid organ and its presence is essential for the development of peripheral lymphoid tissues and their associated adaptive i...
