Eighteen free-ranging female woodland caribou were captured in northern Alberta in January and February 1993. Blood was collected into ethylenediaminetetraacetate (EDTA) tubes which were packaged in coolers containing ice packs, and transported to the laboratory where they arrived within 48 hrs of collection. Complete blood counts (CBC) were performed on five consecutive days to assess the stability of hematological parameters. Average values of hematocrit (HCT), mean cell hemoglobin (MCH), mean cell volume (MCV), red cell distribution width (P-J3W), white blood cell count (WBC), and red blood cell count (RJ3C) remained stable with no statistically significant changes occurring during 5 days of post-collection storage at 4°C. Mean PvBC values exhibited significant differences (p<0.05) between geographic locations. Mean platelet volume (MPV) increased significantly (p<0.001) with storage time, while platelet (PLT) values decreased (p<0.001) over time and were significantly different (p<0.01) between locations. For optimal hematological results, it is recommended that sample analysis be performed within 24 hours of blood collection; however, if caribou blood samples are properly stored at 4°C, useful information may be obtained from stable parameters up to 5 days following collection.

Abstract Background School-aged children (SAC) are a high-risk demographic group for infectious diseases and malnutrition. The objective of this study was to assess the burden and the effect of Plasmodium falciparum and Schistosoma haematobium infections on the haematological indices in SAC and the confounding influence of malnutrition on the outcomes. Methods This cross-sectional study was conducted in SAC 4–14 years old living in Ikata, Bafia and Mile 14-Likoko in Muyuka, Cameroon. Anthropometric measures of malnutrition were obtained and blood samples collected were used for detection of malaria parasites by Giemsa-stained blood films using light microscopy and complete blood count analysis using an automated haematology analyser. Urine samples collected were used to detect micro haematuria with the aid of reagent strips and the eggs of S. haematobium by urine filtration technique. Multiple linear regression model was used to examine influence of independent variables on haematological parameters. Results Out of the 606 SAC examined, the prevalence of single infections with Plasmodium or S. haematobium and co-infection with both parasites was 16.2, 16.3 and 8.3%, respectively. Overall, malaria parasite (MP), urogenital schistosomiasis, malnutrition, anaemia, haematuria, microcytosis and thrombocytopenia was prevalent in 24.4, 24.6, 25.9, 74.4, 12.2, 45.4 and 11.1% of SAC, respectively. A significant linear decline (P = 0.023) in prevalence of P. falciparum infection with the severity of stunting was observed. Factors that significantly influenced haematological parameters included haemoglobin: age, stunting and MP; haematocrit: age and MP; white blood cell count: age; red blood cell count; age and MP; lymphocyte counts: stunting; mean cell volume: age; mean cell haemoglobin: age and stunting; mean cell haemoglobin concentration: sex, stunting and red cell distribution width-coefficient of variation: sex, age and stunting. Conclusions Malnutrition, Plasmodium and S. haematobium infections are common while anaemia is a severe public health problem in Muyuka, Cameroon. The interaction between haematological parameters with malaria parasites as well as linear growth index was negative and other interactions indicate systemic inflammation. While findings provide contextual intervention targets to ensure the judicious use of the limited resources, there is need for regular monitoring and proper treatment to improve the health of the underserved population.

Hemotherapy using whole blood and its components is being increasingly used in veterinary therapy. Since it is important to store animal blood while maintaining acceptable hematological, blood gas, and biochemical characteristics, increasing our knowledge of available technologies for strategic blood storage is imperative. Thus, we aimed to assess the hematological, blood gas, and biochemical changes in donkey whole blood using blood bags with two different types of storage agents. Eight adult healthy male donkeys were used; 900 mL of blood was collected from each, with 450 mL stored in citrate-phosphate-dextrose and adenine bags (CPDA-1) and 450 mL stored in bags containing citrate-phosphate-dextrose, adenine, mannitol, and sodium chloride (CPD/SAG-M). Both bags were kept refrigerated between 1 and 6 °C for 42 days. Blood samples were removed from the bags eight times (T): T0 (immediately after blood collection), T1, T3, T7, T14, T21, T35, and T42 (1, 3, 7, 14, 21, 35 and 42 days after storage). Hematological, blood gas, biochemical, and microbiological parameters were assessed. The CPDA-1 bags had a higher packed cell volume when compared to CPD/ SAG-M. The red blood cell count reduced by around 19% in both the bags due to hemolysis, which was confirmed by an increase in plasma hemoglobin. The white blood cell count; pH; concentrations of glucose, sodium, bicarbonate, and 2,3 diphosphoglycerate were reduced in both bags. Meanwhile, pO2, pCO2, lactate dehydrogenase, and levels of potassium increased in the CPDA-1 and CPD/SAG-M bags. Blood bags were efficient for the storage of donkey blood for up to 42 days.

Abstract Growth and differentiation factor 11 (GDF11) is a member of the transforming growth factor β superfamily. Previous studies have shown that GDF11 decreases with age and has antiaging effects; however, such reports are controversial. We choose 152 subjects covering a large age range (2 hours to 75 years) to measure serum GDF11. Twenty-two hematological variables and 13 biochemical values were measured. Pearson’s analysis found a significant correlation between GDF11 and age (p = .0000, r = .4898), as well as serum creatinine, uric acid, triglycerides, red blood cell count, hemoglobin, hematocrit, and platelet volume distribution width. GDF11 negatively correlated with aspartate transaminase, white blood cell count, platelet count, lymphocyte count, monocyte count, mean platelet volume, and plateletcrit. Interestingly, we found GDF11 increases in people aged 20–30 years, holds steady in people aged 30–50 years, and increases in people older than 50 years. The results suggest that GDF11 serves different roles along the life span. The current actual evidence supports that GDF11 is helpful to promote aging.

Agranulocytosis is a rare but potentially lethal adverse effect of sulfasalazine. We report a case of sulfasalazine-associated agranulocytosis that occurred in a 79-year-old woman who had been taking the drug for approximately seven weeks. The patient had discontinued the drug on her own initiative nine days prior to admission. The patient was admitted with complaints of hoarseness, fever, odynophagia, and malaise. The total white blood cell count was 600/mm3 with a differential of 0% neutrophils, 8% bands, 67% lymphocytes, and 25% monocytes; a bone marrow aspirate and biopsy revealed maturation arrest. The patient's peripheral white blood cell count and differential progressively increased over the nine-day hospital course. Upon discharge the white blood cell count was 12 000 cells/mm3 with 66% neutrophils, 8% bands, 16% lymphocytes, and 10% monocytes. Complete blood counts should be performed periodically in patients receiving sulfasalazine, especially during the first two months of therapy. Pharmacists should counsel patients to discontinue the drug and consult their physician immediately if they develop unexplained fever, chills, sore throat, malaise, or other nonspecific illness during the initial two months of treatment.

Abstract Heritability (h2) indicates the extent to which genes contribute to the observed inter-individual variation in a phenotype. Traits that have a high h2 may be fruitful targets of a subsequent genome screen to identify quantitative trait loci (QTL) and the genetic variants underlying them. We have estimated the heritabilities of measurements that commonly comprise a complete blood cell count (CBC) for members of the San Antonio Family Heart Study (table). The number of white blood cells per μL of blood (WBC) was not under genetic influence (h2 = 0.160, p = 0.253), however, the individual components of the differential (lymphocyte, monocyte, and granulocyte percentage) did appear to be. Red blood cell count (RBC) had the highest heritability (h2 = 0.638, p < 0.001) with both the mean corpuscular volume (MCV) and the red cell distribution width (RDW) demonstrating moderate heritability. The platelet count (Plt) and the mean platelet volume (MPV) had a mild genetic influence that was nominally significant. Currently, the fourth longitudinal examination of this cohort is in progress and to date we have measurements for 154 Mexican American subjects in 16 nuclear families. If prior recruitment rate is maintained, bivariate analyses assessing pleiotropy between traits may be available for presentation. Some of these traits have been investigated previously, but for many these are the first reported h2 estimates to our knowledge. This investigation is a necessary first step to understanding the contributions of genes to these important clinical measurements and to the elucidation of the biological pathways involved in their regulation, which may lead to improved diagnostics and therapies to treat blood cell-related disorders.

Mercury toxicity in tilapia, Oreochromis niloticus, (Linnaeus, 1758) was investigated by the hematological parameters after long-term (14 days) exposure to various Hg concentrations (0.02, 0.002, 0.0002mg/L Hg). Test groups were set up with three replicates for each concentration, plus the control group. Blood samples were collected from six individuals for each concentration at 0, 3, 7, 10 and 14 days of exposure. The hematological parameters analyzed were: total red blood cell count (RBC), hemoglobin concentration (Hb), hematocrit (Ht), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), total white blood cell count (WBC) and differential leukocyte counts and total thrombocyte count (Tr). There were no significant differences among the mean hematological values at the different Hg concentrations indicating that Hg at the concentrations studied was not toxic to tilapia.

Objective: Previous studies reported independent associations of hematological parameters with risk of incident type 2 diabetes, although limited data are available on associations of these parameters with insulin resistance (IR) and (especially) pancreatic β-cell dysfunction in large epidemiological studies. Our objective was to evaluate the associations of hematological parameters, including hematocrit (HCT), hemoglobin (Hgb), red blood cell count (RBC), and white blood cell count with IR and β-cell dysfunction in a cohort of nondiabetic subjects at high metabolic risk. Methods: Nondiabetic subjects (n = 712) were recruited in Toronto and London, Ontario, Canada, between 2004 and 2006, based on the presence of one or more risk factors for type 2 diabetes mellitus including obesity, hypertension, a family history of diabetes, and/or a history of gestational diabetes. Fasting blood samples were collected and oral glucose tolerance tests administered, with additional samples for glucose and insulin drawn at 30 and 120 min. Measures of IR included the homeostasis model assessment (HOMA-IR) and Matsuda’s insulin sensitivity index, whereas measures of β-cell dysfunction included the insulinogenic index divided by HOMA-IR as well as the insulin secretion-sensitivity index-2. Associations of hematological parameters with IR and β-cell dysfunction were assessed using multiple linear regression and analysis of covariance with adjustments for age, gender, ethnicity, smoking, cardiovascular disease, systolic and diastolic blood pressure, and waist circumference. Results: HOMA-IR increased across quartiles of HCT, Hgb, RBC, and white blood cell count after adjustment for age, gender, ethnicity, and smoking (all P (trend) <0.0001). Similarly, there was a strong stepwise decrease in the Matsuda’s insulin sensitivity index across increasing quartiles of these hematological measures (all P (trend) <0.0001). The associations remained significant after further adjustment for previous cardiovascular disease, blood pressure, and waist circumference (all P (trend) <0.0001). Similarly, there was a strong pattern of decreasing β-cell function across increasing quartiles of all hematological patterns (all P (trend) <0.0001). The findings for HCT, Hgb, and RBC were attenuated slightly after full multivariate adjustment, although the trend across quartiles remained highly significant. Conclusion: These findings suggest that standard, clinically relevant hematological variables may be related to the underlying pathophysiological changes associated with type 2 diabetes mellitus. In a large sample of non-diabetic subjects with metabolic risk factors, hematological parameters were significantly associated with insulin sensitivity and β-cell dysfunction, the main physiological disorders underlying type 2 diabetes.

Vitamin C is an essential dietary supplement that plays a vital role in battling health conditions. The antioxidant has positive effects on the functioning of the body. The purpose of this study is to investigate the outcome of varying concentrations of Vitamin C on the hematological parameters of Swiss Albino mice. Four albino mice were separated and accommodated in similar caging conditions. Three of them were orally administered with 250mg/kg, 500mg/kg, and 1000mg/kg Vitamin C powder, along with their diet. The fourth one was kept as control, in order to provide a standard value for future comparison. After 30 days of administration of the Vitamin C, the red blood cell count, the white blood cell count, the hemoglobin concentration, the platelet cell count, and the packed cell volume of the blood samples were tested.
