Aldose reductase inhibitor
A class of drugs used to prevent eye and nerve damage in diabetes. Aldose reductase is an enzyme that is normally present in the eye and in many other parts of the body. It helps change glucose into a sugar alcohol called sorbitol. Too much sorbitol trapped in eye and nerve cells can damage these cells, leading to retinopathy (retinal disease) and neuropathy (nerve disease). Drugs that prevent or slow the action of aldose reductase may represent a means to prevent or delay these complications of diabetes.
Aldrec
Trade name of the insecticide aldrin. See: Aldrin and dieldrin.

Aldrin and dieldrin
The common names of two structurally similar compounds that were once used as insecticides. They are chemicals that are made in the laboratory and do not occur naturally in the environment.

Alexander disease
A slowly progressive and ultimately fatal brain disorder that most commonly occurs in children. The infantile form of the disease is characterized by megalencephaly (an abnormally large head), seizures, spasticity and developmental retardation. It leads to death usually within the first decade. Patients with the juvenile and adult forms of Alexander disease typically experience ataxia and spasticity and a more slowly progressive course. The classic hallmark of all forms of Alexander disease is the presence of Rosenthal fibers, abnormal inclusions in astrocytes that contain the intermediate filament protein GFAP. Mutations in the gene for GFAP (glial fibrillary acidic protein) cause Alexander disease, the first known example of a primary genetic disorder of astrocytes, one of the major cell types in the vertebrate CNS. The disease was first described by W. Stewart Alexander, a New Zealand pathologist, in 1949.
Algia
Word ending indicating pain, as in arthralgia (joint pain), cephalgia (headache), fibromyalgia, mastalgia (breast pain), myalgia (muscle pain), and neuralgia (nerve pain). Derived from the Greek algos meaning pain.

Alkaline phosphatase
An enzyme made in the liver, bone, and the placenta and normally present in high concentrations in growing bone and in bile. Alkaline phosphatase is released into the blood during injury and during such normal activities as bone growth and pregnancy. It is measured in a routine blood test. Abnormally high blood levels of alkaline phosphatase may indicate disease in bone or liver, bile duct obstruction, or certain malignancies. The enzyme is often elevated in the leukemic cells in chronic myelogenous leukemia. Abnormally low levels of alkaline phosphatase is a genetic condition called hypophosphatasia which results in bone deformities. The enzyme is termed alkaline phosphatase because it works under alkaline (non-acidic) conditions, as opposed to acid phosphatase.
