| 설명 | 적혈구의 기능은 산소를 운반하는데 있다. 적혈구 속에 산소와 결합을 하여 산소를 운반하는 혈색소라는 물질이 있다. 철은 이 혈색소의 중요한 부분을 이루는 것으로 철이 없으면 혈색소가 만들어질 수가 없다. 혈색소가 없으면 역시 적혈구도 만들어지지 않으므로 체내에 철이 부족하면 빈혈이 생긴다. 이 철결핍성 빈혈은 빈혈의 원인 중에서 가장 흔한 것이다(약 25%를 차지한다). 철저장량의 저하-결핍, 혈청철농도의 저하, 트란스페린량 상승, 트란스페린포화도의 저하, 혈색소농도 또는 헤마토크리트의 저하, 저색소성대적혈구를 특징으로 하는 빈혈로서, 생체 내에서 철이 장기에 걸쳐 결핍되며 그 때문에 혈색소 생산 감소에 의해 일어난다. 창자에서의 철흡수량 부족, 철의 수요 증대(유아기, 사춘기, 임신), 철소실과잉(출혈)에 의해 일어나며, 특히 사춘기에서 폐경기까지의 여성에게 많다. 증상으로서는 얼굴창백, 피로감, 피부창백, 손톱 변화(스푼 모양) 등을 나타낸다. 구강 영역에서는 혀의 접촉통, 발적, 건조감, 삼킴곤란을 수반하면 플러머-빈슨(Plummer-Vinson)증후군이라고 한다. 혈액 소견은 혈청철은 저하하며, 철결합능력의 상승, 저색소성 작은적혈구성을 나타낸다. |

| neonatal diseases and abnormalities | Diseases existing at birth and often before birth, regardless of causation. Of these congenital diseases, those characterised by structural deformities are termed abnormalities. (12 Dec 1998) |
|---|---|
| neonatal heart failure | <radiology> most likely cause, premature: patent ductus arteriosus, full term: hypoplastic left heart, 2nd week: coarctation and VSD aetiology, valvular stenosis, mitral stenosis, aortic stenosis, aortic coarctation, vein of Galen aneurysm, infantile haemangioendothelioma of liver, hypoplastic left heart see also: congestive heart failure in kids (12 Dec 1998) |
| neonatal hepatitis | Hepatitis in the neonatal period presumed to be due to a variety of causes, chiefly viral; characterised by direct and indirect bilirubinaemia, hepatocellular degeneration, and appearance of multinucleated giant cells; may be difficult to distinguish from biliary atresia, but is more likely to end with recovery, although cirrhosis may develop. Synonym: giant cell hepatitis. (05 Mar 2000) |
| neonatal herpes | Herpes simplex virus type 1 or 2 infection transmitted from the mother to the newborn infant, often during passage through an infected birth canal; severity varies from mild to fatal generalised infection, the latter especially with primary maternal genital herpes. (05 Mar 2000) |
| neonatal hypoglycaemia | Familial onset of symptomatic hypoglycaemia during infancy, with persistently low blood glucose; a variant form is leucine-induced with hyperinsulinism and variable mental retardation. (05 Mar 2000) |
| neonatal isoerythrolysis | Isoerythrolysis in the newborn animal, haemolytic icterus of the newborn. (05 Mar 2000) |
| neonatal jaundice | Icterus which can be accentuated by many factors including excessive haemolysis, sepsis, neonatal hepatitis or congenital atresia of the biliary system. Synonym: physiologic icterus, jaundice of the newborn, neonatal jaundice, physiologic jaundice. (05 Mar 2000) |
| neonatal line | In deciduous teeth, a line of demarcation between prenatal and postnatal enamel. Synonym: neonatal ring. (05 Mar 2000) |
| neonatal lupus | Lupus erythematosus occurring in newborn children of mothers who had lupus during pregnancy; anti-SSA antibodies usually should be screened for; 50% have anti-nuclear antibodies. A variety of skin lesions are seen, which can resolve or leave scarring; the syndrome usually resolves; however cardiac manifestations can be fatal. Some children develop systemic lupus later in life. (05 Mar 2000) |
| neonatal medicine | The art and science of caring medically for the newborn. (12 Dec 1998) |
| neonatal mortality rate | The number of children dying under 28 days of age divided by the number of live births that year. The neonatal mortality rate in the united states, which was 8.4 per 1,000 live births in 1980, declined to 5.8 per 1,000 live births in 1990. (12 Dec 1998) |
| neonatal nursing | The nursing specialty that deals with the care of newborn infants during the first four weeks after birth. (12 Dec 1998) |
| neonatal pulmonary venous hypertension | <radiology> With cardiomegaly, hypoplastic left heart, critical aortic stenosis, cor triatriatum, pulmonary venous atresia, normal heart size, infradiaphragmatic TAPVR (12 Dec 1998) |
| neonatal ring | In deciduous teeth, a line of demarcation between prenatal and postnatal enamel. Synonym: neonatal ring. (05 Mar 2000) |
| neonatal screening | The identification of selected parameters in newborn infants by various tests, examinations, or other procedures. Screening may be performed by clinical or laboratory measures. A screening test is designed to sort out healthy neonates from those not well, but the screening test is not intended as a diagnostic device, rather instead as epidemiologic. (12 Dec 1998) |
