The proportion of sickle haemoglobin [HbS] was determined in 170 sickle-cell-trait individuals; 75 [44.1%] individuals had HbS% > 38%, 54 [31.8%] had HbS% between 31% and 38% and 41 [24.1%] had HbS% < 31%. There was positive correlation between HbS% and haemoglobin concentration, packed cell volume, mean corpuscular haemoglobin, mean corpuscular volume and target cell percentage. Multiple regression analysis indicated that measurement of haemoglobin concentration, mean corpuscular haemoglobin and target cell percentage could be used to predict the HbS%

Camels are regarded as the ship of the desert, being used for transporting humans and their goods. They are also raised for milk, meat, hides and wool. Normal haematological values are important as disease diagnostic aid as they are vital indicator of the animals’ health status. Haematological parameters of one- humped camels (Camelusdromedarius) were determined in this study. 60 one- humped camels (Camelusdromedarius) were selected in sokoto and their blood samples were analyze using standard procedures for haematological parameters. [Packed cell volume (PCV), red blood cells (RBC), haemoglobin (Hb),white blood cells (WBC), neutrophils, eosinophils, Basophils, monocyte, lymphocyte, mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), and mean corpuscular haemoglobin concentration (MCHC)].For all the parameters, only neutrophils and MCV values showed significant variation between sexes with male camels having higher values than females. There is variation in the range values for all the parameters between sexes except Basophils, Monocyte and Lymphocyte. Based on the results of this study, the values were similar in both sex except in neutrophils and mean corpuscular volume indicating insignificant effect of sex on most of the haematological parameters.

Total body water (TBW) is increased after cardiopulmonary bypass (CPB) resulting in tissue oedema and organ dysfunction. Ultrafiltration has been used to reduce this accumulation of water, although conventional ultrafiltration seemed ineffective in reducing the rise in TBW after CPB in our clinical experience. We describe a modified technique in which ultrafiltration is performed in the first 10 minutes after the patient is weaned from bypass, returning nearly all the blood in the circuit to the patient and elevating the haematocrit (Hct) to any predetermined level. We carried out a pilot study on 21 children aged 4-144 months undergoing open-heart surgery and CPB for congenital heart defects. They were divided into three comparable groups: (1) controls (n = 6); (2) conventional ultrafiltration (n = 7); and (3) modified ultrafiltration (n = 8). TBW (bio-impedance), Hct, osmolality, mean corpuscular volume and mean corpuscular haemoglobin concentration were recorded at frequent intervals. Control patients showed elevation of TBW by 18.2% median (range 14.5-20.3), conventional ultrafiltration by 12.4% (7.9-15.0), modified ultrafiltration by 5.7% (4.5-7.1) (p < 0.0001 compared to controls, p < 0.005 compared to conventional ultrafiltration, Mann-Whitney U test). Hct could be elevated to preoperative levels only by the modified method. Mean corpuscular volume, and mean corpuscular haemoglobin concentration osmolality were unaltered. Ultrafiltration by the modified method was more effective than conventional ultrafiltration in reducing the rise in TBW and elevating Hct after CPB.

Haematological and some biochemical determinations were made on the blood of six White Fulani heifers monthly for a period of twelve months in order to investigate any normal seasonal variations in the levels of some of these components. It was found that packed cell volume, haemoglobin and red cell count values were higher during the relatively dry months of the year than the wet months. These changes can possibly be explained by change in the water content of the serum since body water content would decrease with decrease in haemoconcentration. Total leucocyte count, mean corpuscular haemoglobin concentration and total serum protein tended to increase during the rains and were lower in the dry months, while there were no appreciable seasonal differences observed in the levels of mean corpuscular volume, mean corpuscular haemoglobin, inorganic phosphorus and calcium. However, mean corpuscular volume appeared to increase with increasing age

Haematological analysis was performed on 27 adult specimens of Carassius auratus irrespective of sex in 2003 and on 32 juveniles of distinguished sex in 2004. In this study we found that the ploidy level affected significantly (p < 0.01) the values of the erythrocyte count, mean corpuscular volume and mean corpuscular haemoglobin. Although we did not prove any significant effect of sex in juvenile diploids of C. auratus on the values of erythrocyte profile, the erythrocyte count, haematocrit value and haemoglobin content value were higher for males than for females. The erythrocyte count decreased significantly (p < 0.01) with increasing ploidy level. The index of haemoglobin content followed the same trend of a decreasing mean value with increasing ploidy level. Mean corpuscular volume and mean corpuscular haemoglobin increased with the increasing ploidy level (p < 0.01). Haematocrit value and mean corpuscular haemoglobin concentration did not significantly differ from the point of view of the ploidy level.

The Impact

Background: Vitamin D has a steroid- and an anabolic-resembling chemical structure. Vitamin D is essential for many processes in the human body after hydroxylation. Aims of the Study: To investigate the impact of 25-hydroxy-vitamin D plasma concentrations on the blood parameters number of erythrocytes, hematocrit, mean corpuscular hemoglobin and mean corpuscular volume. Methods: Serial assessments were done in 290 patients with multiple sclerosis and repeated after a mean interval of 245 days. A recommendation for vitamin D supplementation was given in case of a concentration lower than 20 ng/mL combined with a prescription of a formulation containing vitamin D but not vitamin K. Results: There was a fall of vitamin D in 119 subjects and a rise in 164, while no change appeared in 7 participants. When vitamin D values went down between both assessments moments, the computed increase of mean corpuscular haemoglobin was significantly lower compared with the rise of mean corpuscular haemoglobin associated with a vitamin D elevation. When vitamin D declined, the computed fall of mean corpuscular volume fall was significantly lower compared with the decrease of mean corpuscular volume, when vitamin D rose. Positive correlations were found between differences of vitamin D and mean corpuscular haemoglobin, respectively mean corpuscular volume. Inverse relations appeared between disparities of vitamin D and erythrocytes, respectively haematocrit. Conclusions: The elevation of vitamin D plasma levels provides enhanced preconditions for a better tissue oxygenation on a cellular level.

Blood Clotting Time

As a consequence of hypothermia (15 °C rectal temperature) in the rat and the hamster, there are increases in red cell fragility and in blood clotting time and a decrease in prothrombin time. In the hypothermic hamster there are significant increases in haemoglobin and erythrocyte count but mean corpuscular volume, mean corpuscular haemoglobin content, and serum protein levels are not altered. These findings indicate that, unlike the hypothermic rat, the hypothermic hamster has an increased haematocrit as a consequence of increased release or decreased destruction of erythrocytes rather than as a consequence of increased cell size and decreased plasma volume. Hypothermia causes a marked leukopenia in both the hamster and the rat but causes an alteration in the relative numbers of lymphocytes and neutrophiles only in the rat.
