Some Biochemical Studies On Hemoglobin

The function of hemoglobin is the transportation of oxygen from lungsto tissues for use in respiration, and the removal of CO2 from the tissues. Inorder for hemoglobin to fulfill its physiologic role, it must bind to oxygen with an appropriate degree of affinity. Hemoglobinopathies are diseases that affecting the oxygen carrying capacity of hemoglobin. This work represents some biochemical studies oThe subject of this work were 146 children and adults divided to, 44cases were school-age children «8-14 years old) 25 males and 19 females,and 1 02 cases were adults (15-72 years old) 81 males and 21 females. Allindividuals under investigation were from urban and rural areas of Dakahliagovernorate, Egypt. Any diseases were taken in consideration.One ml of venous blood taken from each individual the samples werecollected on heparin as anticoagulant, each sample of whole blood was usedfor determination or’ (hemoglobin concentration, methemoglobin percentageand carboxyhemoglobin percentage) by using OSM3 hemoximeter.The findings obtained in this study can be summarized as follows:1- Hemoglobin: 1- The total hemoglobin concentration was varied significantly with age. Hemoglobin was found to be significantly lower in school- age children «8-14 years), it was ranged between 12.0 ± 0.4 gm/dl and 12.6 ± 0.2gm/dl, hemoglobin was then increased in adults (15-48 years), it
