Steroid thymus atrophy

Zinc controls many of the reactions of the human immune system to invading bacteria, viruses and cancer cells.  Zinc is required for white blood cells to track down and kill invading bacteria and viruses (called chemotaxis).  Without sufficient zinc the thymus gland (which produces a white blood cells called a T-cell) shrinks (called atrophy).  While the most prominent effect of zinc deficiency is a functional decline in late-responding T-cells (thymus cell), zinc is also needed for fast-responding white blood cells called neutrophils.   Without adequate zinc the immune response runs out of control and massive inflammation results.

A controlled clinical trial has never been reported for any medical or surgical modality used to treat myasthenia gravis. All recommended regimens are empirical and experts disagree on treatments of choice. Treatment decisions should be based on knowledge of the natural history of disease in each patient and the predicted response to a specific form of therapy. Treatment goals must be individualized according to the severity of disease, the patient's age and sex, and the degree of functional impairment. The response to any form of treatment is difficult to assess because the severity of symptoms fluctuates. Spontaneous improvement, even remissions, occur without specific therapy, especially during the early stages of the disease.

Anterior lobe: Secretions here are the somatotropic, or growth hormone (STH or GH), which regulates cell division and protein synthesis for growth; adrenocorticotropic hormone (ACTH), which regulates functional activity of the adrenal cortex; thyrotropic hormone (TTH or TSH), which regulates functional activity of the thyroid gland; and prolactin, also called lactogenic hormone, which induces secretion of milk in the adult female. The gonadotropic hormones are as follows: in women, follicle-stimulating hormone (FSH) stimulates development of ovarian follicles and their secretion of estrogen; in men, it stimulates spermatogenesis in the testes. In women, luteinizing hormone (LH) stimulates ovulation and formation of the corpus luteum and its secretion of estrogen and progesterone. In men, LH also called interstitial cell-stimulation hormone (ICSH), stimulates testosterone secretion.
