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.

Monitoring of changes in some blood laboratory parameters in 34 horses after ingesting freshly harvested maize that was to be used for ensiling, heavily contaminated with young Datura stramonium plants, is described. For a 7-day period the following parameters were monitored: haemoglobin content (HGB), red blood cell counts (RBC), white blood cell counts (WBC), haematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), differential white cell counts (DWC), erythrocyte sedimentation rate (ESR), protein fractions, aspartate aminotransferase (AST), lactate dehydrogenase (LDH), total bilirubin (TB), direct bilirubin (DB), blood glucose (Glu), total protein (TP), globulin (Glob) and albumin (Alb). The intoxication was accompanied by erythrocytosis, leukocytosis, regenerative left shift neutrophilia, lymphopaenia, eosinopaenia, increased haematocrit values, low erythrocyte sedimentation rate, hyperglycaemia, bilirubinaemia, hypoproteinaemia and increased activity of AST and LDH. No changes occurred in the mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), albumin, globulin and globulin fractions (a1, a2, b1, b2 and g). The blood parameters returned to normal between post-intoxication days 2 and 5. The observed changes in clinical chemistry indices could be used in the diagnosis, differential diagnosis and prognosis of Jimson weed intoxication.

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.

The present paper extends the knowledge of selected blood indicators in six species of feathered game such as helmeted guineafowl (Numida meleagris), common pheasant (Phasianus colchicus), Japanese quail (Coturnix coturnix japonica), chukar (Alectoris chucar), grey partridge (Perdix perdix) and wild turkey (Meleagris gallopavo), reared in the Czech Republic and Europe. The red blood cell (RBC) values in individual species of feathered game ranged as follows: the mean RBC counts varied in a range of 2.10 - 2.58 T/l; haematocrit values were in a range of 0.33 - 0.39 1/1; haemoglobin concentration varied in a range of 101.20 - 129.13 g/l; mean corpuscular haemoglobin concentration (MCHC) ranged from 28.63 to 35.44%; mean corpuscular haemoglobin (MCH) varied in a range of 46.15 - 62.07 pg and the mean corpuscular volume (MCV) was 147.66 - 178.20 fl. Except for the total concentration of haemoglobin and the mean corpuscular haemoglobin concentration, no significant differences were found between the mean values of RBC values in individual species of feathered game. However, some differences between species were found in white blood cell (WBC) values, ranging as follows: the total WBC count ranged from 13.55 to 26.90 G/l, basophil granulocytes from 0.011 to 0.110 G/l, eosinophil granulocytes from 0.011 to 0.593 G/l, neutrophil granulocytes from 1.868 to 6.661 G/l, lymphocytes from 10.937 to 20.922 G/l and monocytes from 0.034 to 0.199 G/l. Most values showed significant (P ⪬ 0.05) to highly significant (P ⪬ 0.01) interspecies differences. The main goal of the study was to investigate selected haematological indicators in six major species of feathered game.

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%
