Dalteparin Sodium
Dalteparin Sodium A low-molecular-weight fragment of heparin, prepared by nitrous acid depolymerization of porcine mucosal heparin. The mean molecular weight is 4000-6000 daltons. It is used therapeutically as an antithrombotic agent. (From Merck Index, 11th ed)
RELATED TERMS--------------------------------------
Heparin
A highly acidic mucopolysaccharide formed of equal parts of sulfated D-glucosamine and D-glucuronic acid with sulfaminic bridges. The molecular weight ranges from six to twenty thousand. Heparin occurs in and is obtained from liver, lung, mast cells, etc., of vertebrates. Its function is unknown, but it is used to prevent blood clotting in vivo and vitro, in the form of many different salts.
Mean
The sum of the values of all observations or data points divided by the number of observations, an arithmetical average.
Molecular
Refers to the basic building blocks of the genetic material, such as DNA, genes and the other chemicals involved with the functioning of genes.
Index

PREVIOUS AND NEXT TERMS--------------------------------------
Damage, Reperfusion
Functional, metabolic, or structural changes, including necrosis, in ischemic tissues thought to result from REPERFUSION to ischemic areas of the tissue. The most common instance is MYOCARDIAL REPERFUSION INJURY.
Damage, DNA
Drug- or radiation-induced injuries in DNA that introduce deviations from its normal double-helical conformation. These changes include structural distortions which interfere with replication and transcription, as well as point mutations which disrupt base pairs and exert damaging effects on future generations through changes in DNA sequence. If the damage is minor, it can often be repaired (DNA REPAIR). If the damage is extensive, it can induce apoptosis.
Damage, Anoxic Brain
A reduction in brain oxygen supply. Severe hypoxia is referred to as anoxia, and is a relatively common cause of injury to the central nervous system. Prolonged brain anoxia may lead to BRAIN DEATH or a PERSISTENT VEGETATIVE STATE. Histologically, this condition is characterized by neuronal loss which is most prominent in the HIPPOCAMPUS; GLOBUS PALLIDUS; CEREBELLUM; and inferior olives. (From Adams et al., Principles of Neurology, 6th ed, pp1109-11)
Dam, Rubber
Sheets of latex rubber punched and placed over the teeth during dental procedures to isolate the field of operation from the rest of the oral cavity (Jablonski; Illustrated Dictionary of Dentistry, 1982). Rubber dams are useful in preventing the swallowing of instruments or restorations during dental work.
Dalzic
A beta-adrenergic antagonist that has been used in the emergency treatment of cardiac arrhythmias.

Dandy Walker Malformation
A congenital abnormality of the central nervous system marked by failure of the midline structures of the cerebellum to develop, dilation of the fourth ventricle, and upward displacement of the transverse sinuses, tentorium, and torcula. Clinical features include occipital bossing, progressive head enlargement, bulging of anterior fontanelle, papilledema, ataxia, gait disturbances, nystagmus, and intellectual compromise.
