Anemia characterized by a decrease in the ratio of the weight of hemoglobin to the volume of the erythrocyte, i.e., the mean corpuscular hemoglobin concentration is less than normal. The individual cells contain less hemoglobin than they could have under optimal conditions. Hypochromic anemia may be caused by iron deficiency from a low iron intake, diminished iron absorption, or excessive iron loss. It can also be caused by infections or other diseases, therapeutic drugs, lead poisoning, and other conditions. (Stedman, 25th ed; from Miale, Laboratory Medicine: Hematology, 6th ed, p393)

An anemic disease of girls.

A medical name for green-sickness.

A diseased condition in plants owing to lack of certain minerals, due mainly to want of light.

A disease which affects young females, more particularly those who have not menstruated. It is characterized by a pale, lurid complexion, languor, listlessness, depraved appetite and digestion, palpitation, &c. The disease generally goes off on the occurrence of the menstrual flux; but sometimes it is long before this is established, and, at times, the catamenia are in much larger quantity than usual. To this last form M. Trousseau has given the name chlorose hemorrhagique. The blood of chlorosis is generally thin, light-coloured and deficient in red corpuscles; and, according to Piorry, in iron,-achalybhemie; and the clot is in less proportion to the serum than in health. On auscultation, a bellows' sound has been almost invariably detected over the heart, and a continuous blowing sound in the larger arteries, (especially the carotids and subclavians,) re-enforced by each systole of the ventricle, and resembling the buzzing of a humming-top, the cooing of doves, the whistling of air through a key-hole, &c., (see Bruit.) Very similar sounds are heard in the arteries after copious hemorrhage: they seem, therefore, to coincide with enfeebled circulation. Tonics- as iron -are usually required in the treatment, -the disease most commonly occurring in those in whom there is considerable torpor of the system.

Green-sickness; anemia of young women about the time of puberty.

Green-sickness; a form of anemia observed usually in girls from 12 to 20 years of age. The blood picture is that of secondary anemia, but often no cause whatever can be discovered and therefore it has been regarded as a mild primary anemia. The hemoglobin of the blood is reduced in amount out of proportion to the diminution of the red blood cells.

n. [Greek] The green sickness; –a disease in plants.

The green-sickness.
