The present study was carried to determine the changes in haematological parameters in P. falciparum infected patients in Ajeromi Ifelodun area of Lagos, Nigeria. Seventy (70) human subjects comprising of 50 P. falciparum malarial infected and 20 non-infected (control) subjects between 10-60 years were selected for this study. RDT test and microscopy were carried out to ascertain the presence of P. falciparum. They were grouped based on age criteria and level of parasitaemia. This work was carried out in the Department of Biochemistry, Nigeria Institute for Medical Research Laboratory, Yaba, Lagos, Nigeria between August 2016 and January 2017. Blood samples were collected for the determination of P. falciparum, level of parasitaemia and haematological parameters. Haematological parameters were determined using a Coulter A-T Pierce haematology analyzer (Beckman Coulter, Inc. Fullerton, CA, USA), P. falciparum was determined by rapid diagnostic test (RDT) and Microscopy. There was a significant increase in the mean level of total white blood cells (WBC) and red blood cells distribution width (RDW), and a significant decrease in the mean level of haematocrit (HCT), haemoglobin (HGB), red blood cells (RBC), and platelets (PLT) in the malaria infected patients than in the controls (p<0.05). There was also a higher malaria parasite density among malaria infected patients for ages above 20 and a lower malaria parasite density for ages below 20 in this study. The findings of this study show that infection with P. falciparum produces changes in haematological parameters in those infected and tested positive for malaria. The most commonly affected parameters are haemoglobin, haematocrit, white blood cells and platelet count.

SummaryCatechol O-methyltransferase of lysed human red blood cells was assayed under optimal conditions, using saturating concentrations of the substrates, S-adenosyl-L-methionine and 3,4-dihydroxybenzoic acid. The mean enzyme activity found in 24 normal subjects was 29.2 nmol/hr/ml RBC. The mean activity in blood of 33 female unipolar depressives was not significantly different from normal. However, higher enzyme activities were observed in the blood of 11 schizophrenic patients (38.9 nmol/hr/ml RBC). Partially purified enzyme preparations from blood of normal and schizophrenic individuals were indistinguishable with respect to substrate specificities, isoelectric pH values, and ratios of the two O-methylated products. Therefore it is unlikely that any defect in O-methylation which may occur in schizophrenia can be attributed to a change in the intrinsic properties of erythrocyte catechol O-methyltransferase.

Chronic renal failure is one of the more common causes of morbidity and mortality among Sudanese. This study describes altered haemoglobin concentration (Hb), haematochrit percent (Hct), red blood cells count (RBCs), platelet count (Plts) and white blood cells count (WBCs) in patients with chronic renal failure and describes the effect of disease duration on haemoglobin concentration and red blood cells count. Methods: Haematological parameters in (50) patients with Chronic renal failure and (50) age and sex matched controls were evaluated, living in Shendi locality in northern Sudan. The results of this study showed that mean of Hb concentration, RBCs count, Hct percent and platelet count were exhibited significant decreased, but mean of WBCs count was insignificantly increased. Increased duration of the disease lead to significantly decreased on mean of Hb concentration and RBCs count. Chronic renal failure is associated with different degrees of reduced haematological parameters. Also increase duration of the disease lead to significantly decrease in mean of Hb concentration and RBCs count.

Haemagglutination assay and haematological analysis of 143 poults generated as F1 individuals by artificial insemination from randomly selected turkeys of White, Black and Lavender genotypes which are classified by antibody titre was carried out so as to confirm their antibody titre levels in response to sheep red blood cells (SRBC). Results showed that mean values obtained for high and low antibody titres were 7.31 and 2.67 respectively, resulting in the classification of the turkeys into Black high and low, Lavender high and black, and White high and low antibody titres. The genotype’s titre had significant (P <0.05) effect on the packed cell volume (PCV), haemoglobin (Hb), red blood cells (RBC), white blood cells (WBC) and basophil (BAS) of the basal haematological parameters. Genotype’s titre had no significant (P >0.05) effect on the primary response haematological parameters. Meanwhile, the primary response haematological parameters to SRBC antigen varied along the genotypes with the WBC increasing drastically in all the genotypes, signifying the presence of an antigen. The study concluded that the F1 turkey poult population studied diverged along the high and low antibody titre in response to SRBC. Thus, the F1 generation of the high antibody titre genotypes (Black high, White high and Lavender high) can be used as foundation stock for selection of local turkeys for high antibody titre.

A study of the red blood cells, hemoglobin, blood platelets, and the total and individual white blood cells was made on 180 male rabbits of known age and representing fifteen standard breeds. An attempt was made to eliminate or bold constant such variables as age, sex, season, time of examination, technical errors, food, housing, and disease. The mean, variance of the mean, and standard deviation were calculated for each breed sample and for the group as a whole. An analysis of the variance showed that the variation between the breed samples was significantly greater than the variation within the breed samples for the red blood cells, hemoglobin, blood platelets, total white blood cells, basophiles, eosinophiles, and lymphocytes per cubic millimeter and in per cent and the neutrophiles in per cent. No significant variations were detected in the monocytes except when the breeds were divided into heavy and light breeds. No variation in the neutrophiles per cubic millimeter was detected; a large number of the breeds had exactly the same mean neutrophile level. Characteristic blood formulae were found for the various breed samples having an adequate numerical representation. It was concluded that the varying blood formulae could not be explained on any other, except an hereditary (genetic) basis.

Objectives: We aimed to establish a new reference interval of blood cell parameters by classifying and counting blood Cells of 16- to 85-year-old healthy volunteers and observing continuous changes with age. Methods: We analyzed the blood cell parameters of 42,678 cases (men, 24,406; women, 18,272), and compared the blood cell parameters of men and women in different age groups using an independent samples t-test. Using limits of 2.5%–97.5%, a 90% confidence interval was used to develop new reference intervals. Results: Counts of blood cell parameters, including white blood Cells, neutrophils, lymphocytes, monocytes, eosinophils, basophils, red blood Cells, hemoglobin, hematocrit, distribution width of red blood Cells and platelets, were found to differ between men and women in different age groups. These parameters were used to establish a new reference interval of blood Cells. Conclusion: The blood cell parameters of both men and women changed with increasing age. The reference interval that we established will provide more accurate basic evidence for clinical diagnosis and treatment of diseases.

The Lusitano horse is an autochthonous Portuguese breed with a growing worldwide expansion. Our objective was to establish reference intervals for haematological parameters using the haematological cell counter LaserCyte (IDEXX). For this purpose, blood samples from 100 healthy adult horses (13 females and 87 males, ranging from 3 to 25 years of age) were analysed. The reference intervals were estimated following the ASVCP guidelines with the Reference Value Advisor software. The obtained reference intervals were 6.4–10.1 × 1012/L for red blood cells, 30.6–45.1% for haematocrit, 11.6–17.1 g/dL for haemoglobin, 42.8–53.2 fL for mean corpuscular volume (MCV), 15.5–20.8 pg for mean corpuscular haemoglobin (MCH), 33.7–39.4 g/dL for mean corpuscular haemoglobin concentration, 17.8–20.3% for red cell distribution width (RDW), 4.5–10.1 × 109/L for white blood cells, 2.2–6.0 × 109/L for neutrophils, 0.9–4.9 × 109/L for lymphocytes, 0.2–0.5 × 109/L for monocytes, 0.1–0.6 × 109/L for eosinophils, 0.0–0.1 × 109/L for basophils, 78.5–172.2 K/mL for platelets, 4.3–9.4 fL for mean platelet volume, 18.8–24.2% for platelet distribution width, and 0.06–0.12% for plateletcrit. LaserCyte equine reference intervals are transferable to the Lusitano horse for 18 of the 22 analytes studied. Regarding age, significant statistical differences were observed for MCV, RDW, neutrophils and lymphocytes between the mean values of young (3–6 years old), middle-aged (7–14 years old) and old (< 15 years old) age groups. MCH means were statistically significantly different between the three age groups. The haematological reference intervals established in this study might represent a valuable and applicable tool for haematological assessment of adult Lusitano horses, providing useful information that helps clinicians to interpret clinical data.

Effect Of Age

The main aim of the present study was to determine the values of the haematological parameters of dairy sheep reared under intensive and semi-intensive conditions, as well as to test for the effects of age and reproductive stage of the animals on the values of these parameters. In total, 200 clinically healthy Chios sheep from 10 farms of Central Macedonia were used in the study. For the determination of the effect of age 150 sheep were assigned in three groups. Group A consisted of 50 lambs aged 3-6 months (meantSD: 4.45±1.22 months), group Β of 50 non-pregnant ewes into lactation aged 1-3 years (meantSD: 2.18±0.74 years) and group C of 50 non-pregnant ewes into lactation aged more than 3 years (meantSD: 5.88±1.87 years). For evaluating the effect of reproductive status 50 pregnant ewes in dry period were used, 15-30 days before the expected day of lambing (group D), along with the 100 non-pregnant ewes into lactation of groups Β and C (group E). Blood sampling was performed once, in dry ewes from December to January, and in lambs and lactating ewes from March to May. The mean values of the determined haematological parameters were within the range provided by the literature, except for red blood cells count of ewes. The results also showed that haematocrit, haemoglobin concentration and red blood cells, white blood cells, neutrophils, lymphocytes, eosinophils and platelets count were significantly affected by the age; only monocytes and eosinophils count by the reproductive stage of the animals.

The Difference

Introduction. The estimation of malaria parasite density using a microscope heavily relies on White Blood Cells (WBCs) counts. An assumed WBCs count of 8000/µL has been accepted as reasonably accurate in estimating malaria parasite densities due to the challenge to accurately determine WBCs count. Method. The study used 4944 pieces of laboratory data of consented participants of age group less than 5 years. The study compared parasite densities of absolute WBCs, assumed WBCs, and the WBCs reference values in Central Ghana. Ethical approvals were given by three ethics committees. Results. The mean (±SD) WBCs and geometric mean parasite density (GMPD) were 10500/µL (±4.1) and 10644/µL (95% CI 9986/µL to 11346/µL), respectively. The difference in the GMPD compared using absolute WBCs and densities of assumed WBCs was significantly lower. The difference in GMPD obtained with an assumed WBCs count and that of the WBCs reference values for the study area, 10400/µL and 9200/µL for children in different age groups, were not significant. Discussion. Significant errors could result when assumed WBCs count is used to estimate malaria parasite density in children. GMPD generated with WBCs reference values statistically agreed with density from the absolute WBCs. When obtaining absolute WBC is not possible, the reference value can be used to estimate parasite density.

Objectives: Destruction of blood cells and damage to hepatocytes are the hallmark of hepatitis B viral infection. This cross-sectional study was undertaken to evaluate some hematological parameters and biomarkers of liver injury in healthy blood donors infected with the occult and overt hepatitis B attending the University of Abuja Teaching Hospital (UATH) and Nnamdi Azikiwe University Teaching Hospital (NAUTH) Nnewi, Nigeria.  Materials and Methods: A total of 20 overt and 14 occult hepatitis B virus-infected blood donors were confirmed and enrolled using Roche ® COBAS q-PCR from 212 consented pooled subjects. Hematological parameters and absolute CD4+ T-cell count were determined using the Sysmex hematology analyzer and Partec cyflow counter, respectively. Determination of serum Alanine Aminotransferase (ALT) and Alpha Feto-protein (AFP) levels were done spectrophotometrically and ELISA, respectively.  Results: The mean red blood cells, hematocrit, hemoglobin, white blood cells, CD4 and platelet count in the overt group were not statistically significantly different from the occult group p>0.05. However, of the 34 infected subjects, 7 (20.6%), 6 (17.7%), 2 (5.9%), 13 (38.2%), 2 (5.9%) and 4 (11.8%) had abnormally low blood values for red blood cells, white blood cells, hematocrit, hemoglobin, CD4 and platelets respectively. The mean ALT and ALP values from the occult and overt groups were not also significantly different (p>0.05).  Conclusion: This study found a decrease in the values of some blood cells. However, no significant changes in the liver enzymes were found. These infected individuals should be managed to prevent transmission of HBV infection to other people and subsequent destruction of blood cells and damage to liver cells. Future studies could focus on patients with chronic liver diseases/Hepatocellular carcinoma caused by HBV to determine the effects on the liver biomarkers and hematological parameters.

The purpose of this paper is to put up a device for urinary sediment detection with a homemade microscope and a CCD, and to test the feasibility of the device. In this study, we use a capillary to absorb the urinalysis control (UC) which is diluted 500 times, and drip it into a counting pool of a urinary sediment quantitative analysis board (USQAB). In this setup device, we detect 30 counting pools in this analysis board with microscopic examination in total. Further, we count the number of red blood cells (RBC) and white blood cells (WBC) of every counting pool, and calculate the average number of RBC and WBC of 30 counting pools. Though this detection device, we are able to get 30 groups of imaging results clearly while the number of RBC and WBC in each counting pool fluctuates around the mean value. The result indicates that the setup detection device in this experiment is simple and feasible.
