| nutritional encephalomalacia of chicks | A disease of young chicks caused by vitamin E deficiency. Synonym: crazy chick disease. (05 Mar 2000) |

| nutritional energy | The dynamics of nutrition or metabolism. Synonym: nutritional energy. Origin: tropho-+ G. Dynamis, power (05 Mar 2000) |
| nutritional haemosiderosis | A disease seen in black South Africans that results from ingestion of iron in foodstuffs prepared in iron vessels; excessive absorption of iron affects the liver. (05 Mar 2000) |
| nutritional macrocytic anaemia | Macrocytic, megaloblastic anaemia due to deficiency of either folate or vitamin B12. (05 Mar 2000) |
| nutritional marasmus | Extreme weakness and wasting secondary to malnutrition. (05 Mar 2000) |
| nutritional oedema | A form of swelling caused by insufficient protein intake resulting in hypoproteinaemia and low plasma oncotic pressure. (05 Mar 2000) |
| nutritional polyneuropathy | A disorder of multiple peripheral nerves, noted in beriberi, chronic alcoholism, and other clinical states, resulting from thiamin deficiency. (05 Mar 2000) |
| nutritional status | State of the body in relation to the consumption and utilization of nutrients. (12 Dec 1998) |
| nutritional support | The administration of nutrients for assimilation and utilization by a patient by means other than normal eating. It does not include fluid therapy which normalises body fluids to restore water-electrolyte balance. (12 Dec 1998) |
| nutritional type cerebellar atrophy | A restricted type of cerebellar cortical degeneration, affecting particularly the Purkinje cells of the anterior and superior vermis; probably caused by thiamin deficiency; most frequently seen in chronic alcoholics and then called alcoholic cerebellar degeneration. (05 Mar 2000) |
| anaemia, refractory, with excess of blasts | Chronic refractory anaemia with granulocytopenia, and/or thrombocytopenia. Myeloblasts and progranulocytes constitute 5 to 40 percent of the nucleated marrow cells. (12 Dec 1998) |
| antibody excess | In a precipitation test, the presence of antibody in an amount greater than that required to combine with all of the antigen present. (05 Mar 2000) |
| antigen excess | In a precipitation test, the presence of uncombined antigen above that required to combine with all of the antibody; precipitation may be inhibited because the presence of excess antigen gives rise to soluble antigen-antibody complexes, in vivo the resultant antigen-antibody interaction in such an antigen excess may give rise to immune complexes, which have a potential to induce cellular damage; such injury underlies the pathologic changes seen in certain immune complex diseases. (05 Mar 2000) |
| base excess | A measure of metabolic alkalosis, usually predicted from the Siggaard-Andersen nomogram; the amount of strong acid that would have to be added per unit volume of whole blood to titrate it to pH 7.4 while at 37캜 and at a carbon dioxide pressure of 40 mm Hg. (05 Mar 2000) |
| calcium excess | Overly high intake of calcium (hypercalcaemia) may cause muscle weakness and constipation, affect the conduction of electrical impulses in the heart (heart block) lead to calcium stones in the urinary tract, impair kidney function (through nephrocalcinosis), and interfere with the absorption of iron predisposing to iron deficiency. According to the National Academy of Sciences, adequate intake of calcium is 1 gram daily for both men and women. The upper limit for calcium intake is 2.5 grams daily. (12 Dec 1998) |
