Bone marrow disease

Inhibition of IGF-IR autophosphorylation by NVP-ADW742 results in a plethora of pro-apoptotic molecular events that may account for its effectiveness as a single agent and in enhancing the antitumor activity of a broad spectrum of chemotherapeutic and anticancer targeted agents. Initial in vivo proof-of-concept of the potential therapeutic benefit of blocking IGF-IR kinase activity in tumor cells was obtained in an orthotopic multiple myeloma (MM) model of bone and bone marrow disease. In this mice model, MM... 

There are several other metabolic disorders, but because they are not very common, not much is known about them. For example, a disease known as amyloidosis results when enough amyloid protein builds up in one or more organs to cause the organ(s) to malfunction. The heart, kidneys, nervous system and gastrointestinal tract are most often affected. Amyloid (pronounced am -i-loyd) is an abnormal protein that may be deposited in any of the body s tissues or organs. This abnormal protein comes from cells in the bone marrow, so amyloidosis is known as a bone marrow disease. The bone marrow makes protective antibodies that protect against infection and disease. After they have served their function, these antibodies are broken down and recycled by... 

In the case of chronic myelogenons leukemia, routine analyses are made of whole blood and bone marrow to determine the degree of abnormal transcripts derived from cancerons or neoplastic cells. In this way, a marker is provided for the progression or regression of the disease. The technique has also been appUed to patients with solid tnmors. The nse of tyrosine hydroxylase transcripts has been foimd to correlate with micrometastatic bone marrow disease in nemoblastoma, and tyrosine transcript levels are known to relate to the progression (or regression) of melanoma. Other snbstances detectable include prostate-specific markers, notably...

Due to their extensive use and resistance to decomposition, halogenated polyphenyls are almost universal environmental contaminants, present in waste sites, sediments, the human body, water supplies, and elsewhere. They are associated with many toxic and biochemical effects including wasting syndromes, bone marrow diseases, atrophy, chloracne, hyperplasin, liver damage, and cancer. 

Opposed imaging uses in and out of phase imaging techniques. It can be used to detect a small amount of fat within a lesion and for evaluating bone marrow disease. It is a specialised technique that is not routinely used (Dixon 1984). 

Splenectomy in GD shows the typical sequelae of this procedure. The transient elevation of the thrombocyte count may, however, last longer than that observed after splenectomy for other reasons. Elimination of thrombopenia by splenectomy is independent of associated bone marrow disease and occurs even with marked infiltration by GC (Pick 1926, Davidsohn 1928, Bonta 1929, Hunter and Evans 1929, Carling et al. 1933, Logan 1941). An increase in circulating white cells may persist for months with counts up to 30000. Herrlin and Hillborg (1962) saw recurring leukocytosis 4—5 years after splenectomy. There is also some improvement of anemia after splenectomy. 

The presence of antimicrobial drug residues in the edible tissues can cause allergies, toxic effects, changes in the intestinal microbial fauna and acquisition of drug resistance. Chloramphenicol residues in food consumed by humans can even result in aplastic anemia, which causes very serious bone marrow diseases. Nitrofuran antibiotics are known to cause cancer and many other diseases. It is for this reason that most countries that import fish products have banned the use of certain antibiotics (Sanandakumar, 2002).

The first human kidney and bone marrow transplants using cyclosporine were reported in 1978. Oral or intravenous cyclosporine is an immunosuppressant for transplantation of these and other organs and investigations are underway for its possible use in a variety of autoimmune diseases including rheumatoid arthritis, severe psoriasis, and Crohn s disease. Dose-dependent nephrotoxicity (261—264) remains the primary limitation of the dmg and necessitates close monitoring of patients, including measurement of dmg levels in blood. Cyclosporine research has been reviewed (265—274). 

Acyclovir is more effective the more serious the disease and the earher it is given. It has been shown to be efficacious when used systemicaHy in the prophylaxis of HSV infections in immunosuppressed patients, ie, bone marrow transplant recipients (67). Acyclovir therapy appears to be superior to ara-A in the treatment of herpes simplex encephaUtis in humans (68). 

Toxic Effects on the Blood-Forming Tissues Reduced formation of erythrocytes and other elements of blood is an indication of damage to the bone marrow. Chemical compounds toxic to the bone marrow may cause pancytopenia, in which the levels of all elements of blood are reduced. Ionizing radiation, benzene, lindane, chlordane, arsenic, chloramphenicol, trinitrotoluene, gold salts, and phenylbutazone all induce pancytopenia. If the damage to the bone marrow is so severe that the production of blood elements is totally inhibited, the disease state is termed aplastic anemia. In the occupational environment, high concentrations of benzene can cause aplastic anemia. 

Chloroquine is contraindicated in patients with known hypersensitivity. It is a good idea to use chloroquine cautiously in patients with hepatic disease or bone marrow depression and during pregnancy. Children are very sensitive to chloroquine, and the drug should be used with extreme caution in children. 

These dru are contraindicated in patients with known hypersensitivity. Hydroxychloroquine is contraindicated in patients with porphyria (a group of serious inherited disorders affecting the bone marrow or the liver), psoriasis (chronic skin disorder), and retinal disease (may cause irreversible retinal damage). MTX is contraindicated during pregnancy because it is a Pregnancy Category X dmg and may cause birth defects... 

The antipsychotics are contraindicated in patients with known hypersensitivity to the drug s, in comatose patients, and in those who are severely depressed, have bone marrow depression, blood dysera ias, Parkinson s disease (haloperidol), liver impairment, coronary artery disease, or severe hypotension or hypertension.
