A Study on the Normal Value of Red Blood Cell of Korean Primary School Children

ABSTRACT

This study was undertaken on 120 healthy primary school children (male 60, female 60), who live in a fishing village, Geo-Mun island, Chulla-Namdo, in order to investigate normal value of red blood cell. Ages of the children were ranged from six years to twelve years. The author cheked the number of red blood cell, hemoglobin level, hematcrit, mean corpuscular volume(MCV), mean corpuscular hemoglobin(MCH), and mean corpuscular hemoglobin concentration(MCHC). MCV, MCH, and MCHC were calulated by formula of Wintrobe. The results obtained were as follows; 1. The mean value of RBC count was 4,500,000/mm3(range : 3,470,000-5,850,000/mm3) 2. The mean value of hemoglobin level was 12.5gm/dl(range: 11.0~14.0gm/dl). 3. The mean value of hematcrit was 37.0%(range: 32~42%). 4. The mean value of MCV was 83.5 cub. micron(range 71.0~105.3 cub. micron.) 5. The mean value of MCH was 28.3rr(range: 22.2~39.7rr). 6. The mean value of MCHC was 33.8gm/100ml (range: 32.4~35.9/100 ml).
