Erythrocyte Osmotic Fragility of Nera Black Fowls of Two - Age Groups
نویسنده
چکیده
The erythrocyte osmotic fragility and other erythrocyte indices in fowls of two different age groups (7-9 week-old and 49 week-old) were studied using Nera Black strain usually raised commercially for egg production in Nigeria. Erythrocytes in the 49 week-old birds were more fragile than those in the 7-9 week-old at sodium chloride (NaCl) concentrations of 0.2% (p<0.05), 0.7% (p<0.05), 0.8% (p<0.01) and 0.9% (p<0.01). The mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCH) values were also higher in the adults, but the packed cell volume (PCV) was lower. The haemoglobin (Hb) concentration, red blood cell (RBC) count and mean corpuscular volume (MCV) were similar in the two age groups.

* Corresponding author. e-mail: [email protected] or [email protected]. The effect of prolonged use of Iodosteryl, a polyvalent iodophorous compound, as water disinfectant, on the hematology and erythrocyte osmotic fragility of the domestic chicken was investigated. Twenty eight adult male domestic chickens of the Nera black strain were divided into four groups of seven birds p...

Background: The capacity of human HbAA erythrocytes of non-malarious blood to withstand osmotic stress in the presence of five antimalarial drugs, Chloroquine phosphate, Quinine, FansidarTM, CoartemTM and HalfanTM was studied in vitro. Materials and Methods: Aqueous solutions of four increasing concentrations of the drugs used in this investigation were in the order: 0.2%, 0.4%, 0.6% and 0.8% (...

Mild anaemia among patients with hyperthyroidism, reduction in intracranial zinc content of erythrocytes and anti- haemolysis of whole blood of patients with Graves, disease under laboratory Condition are the facts which indicate that although erythrocytes are devoid of receptors for thyroid hormones, they are affected by the excess of these hormones. In order to find out the reasons for suc...

Osmotic fragility (OF) test was conducted in Nigerian human black male erythrocytes stored for Oh, 12h, 24h and 48h. Storage of these human erythrocytes for up to 24h failed to alter significantly their membrane characteristics. A leftward shift in osmotic fragiligrams was noted suggestive of storage-time (age) dependent erythrocyte stability. Mean corpuscular fragility (MCF) diminished with an...
