1. The presence of unusually large red cells in the blood.
2. A condition in which the erythrocytes are larger than normal; such as, in macrocytic anemia and some types of liver disease.

Macrocytosis is present in 1 to 4 percent of the adult population. The most common cause is alcoholism. Other causes include: nutritional deficiencies (B12 and folate), chemotherapy, drug side effects, haemolysis, liver dysfunction, myelodysplasia, as well as, hypothyroidism.

Ptosis, sagging, or pendulous condition of the mammary glands or breasts.

A thickening and loss of elasticity of the walls of the arteries of the blood; especially, but not exclusively, muscular ones as a result of calcification.

1. A complete or marked change of physical form, structure, or substance: During the beginning of winter, an overnight metamorphosis of the pond water in Sam's backyard resulted in ice.
2. A transformation caused by some supposed supernatural powers: In the story Jane was reading, the prince was changed into a frog by metamorphosis caused by the bad witch!
3. In zoology, a complete or marked change in the form of an animal as it develops into an adult: Examples of two metamorphoses involve the change from a tadpole to a frog or from a caterpillar to a butterfly. © ALL rights are reserved.

1. Partial insanity, in which a person's morbid mental state is restricted to one subject, the patient being of sound judgment and having appropriate behaviors regarding all other subjects.
2. An impulsive single act without an apparent motive.

1. Replacement of muscle tissue by fibrous tissue.
2. Chronic myositis with diffuse hyperplasia of the interstitial connective tissue pressing upon and causing atrophy of the muscular tissue.

Necrosis of muscle tissue.

General and nonspecific reversible depression of neuronal excitability, produced by a number of physical and chemical agents, usually resulting in stupor rather than in anesthesia.

1. The degeneration and death of the body’s cells from natural processes.
2. Physiologic or normal death of cells or tissues as a result of changes associated with development, aging, or use.
3. A state of degeneration of a part or tissue in which some portions are alive and others are dead.

1. The death of cells in a tissue or organ caused by disease or injury.
2. Death, or mortification; especially, of a bodily tissue, as a result of the loss of blood supply, corrosion, burning, etc.

The causes of necrosis include insufficient blood supply, but also, other physical agents; such as, trauma, or radiant energy (electricity, infrared, ultraviolet, roentgen, and radium rays); chemical agents acting locally, acting internally following absorption, or placed into the wrong tissue; such as, some medicines cause necrosis if injected into the tissues rather than the vein, and iron dextran (injectable form of iron used in the prevention of iron deficiency) causes necrosis if injected into areas other than the deep muscle or vein.

Regeneration in cases where the new part is unlike anything in the body.

Any disease, deformity, or malformation, of the nails.

1. Correct living, both hygienically and morally.

3. Living in accordance with proper hygienic principles.

The absence of any nucleated erythrocyte precursors in human blood; that is, the normal condition.

1. Diffusion of a solvent through a differentially permeable membrane from a region of low solute concentration to one of high solute concentration.
2. The diffusion of pure solvent across a membrane in response to a concentration gradient, usually from a solution of lesser to one of greater solute concentration.
3. The tendency of a fluid, usually water, to pass through a semipermeable membrane into a solution where the solvent concentration is higher, thus equalizing the concentrations of materials on either side of the membrane.
