Abstract The objective of this study was to characterize and compare the hematological variables (erythrogram, thrombogram, leukogram and plasma metabolites) of three cichlid species: Cichla monoculus, Cichla temensis and Cichla vazzoleri. A total of 45 specimens were captured in Balbina lake, Presidente Figueiredo, Amazonas, Brazil, with the aid of a rod and reel or hand line, with natural or artificial bait: 15 C. monoculus, 15 C. temensis and 15 C. vazzoleri. Their blood was removed by means of caudal puncture of the dorsal aorta, and hematological data were determined in accordance with methodology previously described in the literature. The erythrogram showed similarities between the species, while the thrombogram showed differences between C. vazzoleri and the other species studied (C. monoculus and C. temensis). The total leukocyte counts for C. temensis and C. vazzoleri were higher than those of C. monoculus. The predominant leukocyte in C. temensis and C. vazzoleri was lymphocytes, whereas it was monocytes in C. monoculus. The plasma metabolites showed differences between the three cichlid species, regarding their glucose, cholesterol, urea and potassium levels. It is concluded that these three species present hematological differentiation, thus indicating that they have differentiated blood-cell immune responses and plasma metabolite physiology.

Traumatic brain injuries (TBI) represent a high impact public health problem due to a high rate of death , long term disability and occurrence especially in young adults. Despite several promising animal studies, several parameters were proposed as biological markers and were assessed for this aim. Our study proposes the study of the early biochemical changes in association to hematological parameters for severe TBI patients prognosis. 43 patients with acute TBI were included in study based on clinical, laboratory and imagistic findings. The severity of the TBI was established by Glasgow Coma Scale GCS 3-8. In all patients were evaluated hematologic parameters (Red blood cell count - RBC, Hematocrit, blood Hemoglobin, White blood cell - WBC, Platelet count and biochemical parameters (glucose, urea, creatinine, electrolytes). Outcome was expressed as Glasgow Outcome Scale (GOS), between 1-5. Values were compared to control group -15 cases. Significant early differences in body temperature, heart rate, and systolic blood pressure were observed in TBI group versus control (p[0.05). After correlation, laboratory findings significantly associated to severe outcome - GOS = 1, 2 - (p[0.05) were plasma Na decrease and significant glucose increase. An early increase of temperature and decrease of Na may predict a severe outcome in patients with acute TBI; association with shifts in heart rate and blood pressure, imposes aggressive treatment measures.

SUMMARYThe excretory/secretory (E/S) products of adult Haemonchus contortus comprise of at least 15 polypeptides with molecular weights ranging from 10 to > 100 kDa. These E/S products induce an immune response in infected Texel sheep, as demonstrated by specific IgGI levels and a significant lymphocyte proliferation index. Moreover, immunoblotting analysis revealed that sera of primary H. contortus-infected sheep specifically recognize a 24 kDa E/S product. In addition, sera of challenged sheep react strongly with a 15 kDa E/S product. The other E/S products of H. contortus showed immunoreactivity with serum samples of Haemonchus-infected sheep as well as with samples of sheep harbouring other trichostrongylid infections. These cross-reacting epitopes are the main cause of the lack of specificity of an E/S material- based ELISA. This ELISA can differentiate Haemonchus infections from Nematodirus battus infections, but not from Ostertagia circumcincta or Trichostrongylus colubriformis infections.

Background: Clinical laboratory reference intervals are an important tool to identify abnormal laboratory test results. The generating of hematological parameters reference intervals for local population is very crucial to improve quality of health care, which otherwise may lead to unnecessary expenditure or denying care for the needy. There are no well-established reference intervals for hematological parameters in southwest Ethiopia. Objective: To generate hematological parameters reference intervals for apparently healthy individuals in southwest Ethiopia. Methods: A community-based cross-sectional study was conducted involving 883 individuals from March to May 2017. Four milliliter of blood sample was collected and transported to Jimma University Medical Center Laboratory for hematological analysis and screening tests. A hematological parameters were measured by Sysmex XS-500i hematology analyzer (Sysmex Corporation Kobe, Japan). The data were analyzed by SPSS version 20 statistical software. The non-parametric independent Kruskal–Wallis test and Wilcoxon rank-sum test (Mann–Whitney U test) were used to compare the parameters between age groups and genders. The 97.5 percentile and 2.5 percentile were the upper and lower reference limit for the population. Results: The reference interval of red blood cell, white blood cell, and platelet count in children were 4.99 × 1012/L (4.26–5.99 × 1012/L), 7.04 × 109/L (4.00–11.67 × 109/L), and 324.00 × 109/L (188.00–463.50 × 109/L), respectively. The reference interval of red blood cell, white blood cell, and platelet count in adults was 5.19 × 1012/L (4.08–6.33 × 1012/L), 6.35 × 109/L (3.28–11.22 × 109/L), and 282.00 × 109/L (172.50–415.25 × 109/L), respectively. The reference interval of red blood cell, white blood cell, and platelet count in geriatrics were 5.02 × 1012/L (4.21–5.87 × 1012/L), 6.21 × 109/L (3.33–10.03 × 109/L), and 265.50 × 109/L (165.53–418.80 × 109/L), respectively. Most of the hematological parameters showed significant differences across all age groups. Conclusion: Most of the hematological parameters in this study showed differences from similar studies done in the country. This study provided population-specific hematological reference interval for southwest Ethiopians. Reference intervals should also be established in the other regions of the country.

In several countries, a lot of researches have shown the toxicity of pesticides on farmers. Meanwhile, few of them have dealt with vegetable farmers in Benin. Therefore, this study has been carried out to assess the effects of pesticides on vegetable farmers’ health. This study is conducted on 30 vegetable farmers who used pesticides and 20 subjects as control group. Pesticides used by vegetable farmers and their risky behavior were investigated. Their blood samples were collected and some tests were performed for hematological and biochemical parameters. For the statistical analysis of the results, Student’s test was used. Our investigations revealed that vegetable farmers of Benin were exposed to different active ingredients of pesticides such as (Abamectin, Acetamiprid, Chlorpyriphos ethyl, Cyfluthrin, Cypermethrin, Emamectin benzoat, Flubendiamid, Lambdacyhalothrin, Mancozeb, Profenofos, Spinosad and Spirotétramate). The hematological parameters showed significant decrease in White blood cell (WBC), Red blood cell (RBC), Hemoglobin (HGB), Hematocrit (HTC), Mean Corpuscular Volume (MCV), Platelet (PLT) count among study group. The enzymatic activities of Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT) have significantly raised between vegetable farmers and the control group, while the serum concentration in urea and creatinine showed insignificant difference in the study group. These results suggest that pesticides have adverse effects on vegetable farmers of South of Benin.

A total of 281 specimens of freshwater armored ornamental fish species (Leporacanthicus galaxias, Lasiancistrus saetiger, Cochliodon sp., Hypostomus sp., Pseudacanthicus spinosus, Ancistrus sp. and Rineloricaria cf. lanceolata) were captured at the hydrological basin of Guamá River, Pará, Brazil. The infection by Trypanosoma spp. was inspected. The morphological and morphometric characterization of the parasites and the hematological parameters were determined. Leporacanthicus galaxias and Pseudacanthicus spinosus presented 100% infection prevalence, and the other species showed a variable prevalence of infection. The parasites showed clearly different morphotypes and dimensions, and probably belong to different species. The hematological response to the infection varied with the host. Cochliodon sp. showed no differences between infected and not infected fish. In other species several modifications on some hematological parameters were found, but apparently without causing disease. It is emphasized the possibility of introduction of the parasites in new environments due to the artificial movements of these ornamental fish.

Preeclampsia (PE) is a turmoil in the pregnancy appeared with the onset of hypertension and considerable amount of proteinuria. Extra serum iron is a causative component of oxidative stress concerned in the pathogenesis of preeclampsia. This study is a case control, conducted in 2018, and aimed to determine the iron status in preeclamptics as compared to normotensive pregnancies in Gaza strip. About 100 pregnant women with gestational age between 26 to 36 weeks. Fifty of them were preeclamptics and an equal number were without preeclampsia, aged between 18 to 35 years. Interview questionnaires were used to take sociodemographic and clinical data. Anthropometric evaluation and biochemical analysis were conducted. The SPSS version22 was used for data analysis. There was no statistically difference in the gestational age, gestational number and hemoglobin levels in the cases and controls (p≥ 0.05). In contrast, the body mass index (BMI), systolic, diastolic blood pressure (BP), and uric acid (UA) levels were significantly higher in preeclamptics (P<0.001). As well, the majority of cases were have +2 proteinuria on dipstick testing. Further, serum iron and ferritin levels were significantly higher in preeclamptics. On the other hand, ferritin levels had significant direct correlations with gestational number, previous preeclampsia, BMI, systolic BP, diastolic BP, UA, and proteinuria (P<0.05). Likewise, Iron had significant direct correlation with proteinuria (P<0.05). Preeclamptics have higher hematological parameters levels (iron & ferritin) as compared to normotensive women. However, Iron status of preeclamptic women should be assessed before giving iron supplements as these may cause more harm than benefit.

The purpose of this study is to investigate the effect of aerobic and strength exercises on hematological parameters in sedentary women. To achieve the purpose of this study, a total of 23 volunteers including aerobic exercise group (AE, n: 10), strength exercise group (SE, n:13) were selected as participants. Two different exercises were applied for 4 days a week, throughout 16 weeks, within 60 minutes for each exercise with the intensity of heart rate (HR) 60-70 percent. The HR was measured using a heart rate monitor for each subject.The women's white blood cell (WBC), thrombocyte (PLT), red blood cell (RBC), hemoglobin (HGB), hematocrit (HCT) and mean corpuscular volume (MCV) were measured before and after exercise. For statistical analysis, the Wilcoxon signed-rank test was used for intra-group evaluations, and the Mann Whitney U test was used for inter-group evaluations. After the exercise program, there were a meaningful decrease in the body weight and body mass index (BMI) the women in both intervention groups. In addition, in the hematological results of strength exercise group, some meaningful decreases were determined in the values of RBC, HGB, HCT and MCV (p<0.01). As a results, it was observed that regular aerobic and strength exercises can positively influence the body weight and BMI parameters of sedentary women. Along with this, a meaningful decrease has been found in the values of RBC, HGB, HCT and MCV of strength exercise group compared to aerobic exercise.

Aims and Objectives: This study is to investigate the inorganic composition and the effect of fourteen (14) -day oral administration of aqueous extracts of root, pod and stem of Telfairia occidentalis in rats.Materials and Methods: Plant samples were analyzed for K, P, Mg, Ca, S, Mn, Fe, Cu, Zn, Pb, and Cr using atomic absorption spectrophotometry (AAS). Wister rats of both sexes were assigned to sixteen (16) groups of 4 animals per group. Different animal groups received distilled water and   root, stem, and pod extracts at the doses of 250, 750, 1500, 2250, and 3000mg/kg of body weight. All animals were treated for 14 days and sacrificed on the 15th day.Results: The inorganic composition result showed that potassium (K) was the highest in abundance in all the samples (root, pod, and stem), compared to the other mineral elements. The root contained high levels of potassium and manganese; the stem had magnesium, manganese and iron while the pod contained high amount of potassium, manganese and iron. Hematological assay results showed reduction in the values of white blood cell (WBC) count for higher doses of root extract and all doses (except for 1500mg/kg bw) of pod extract. Platelet count (PLT) was significantly high for root extract at 750mg/kg bw. The stem extract showed a consistent decrease in the red blood cell (RBC) count for all dose administered.Conclusion: Telfairia occidentalis root, pod, and stem may be a good source of inorganic elements. The extracts have varying effects on hematological parameters which may be dosage- and duration- dependent.Asian Journal of Medical Sciences Vol.7(5) 2016 75-80

Background: Cordyla pinnata (C. pinnata) is commonly used in traditional medicine for the treatment of various ailments. The aim of this study was to assess the toxic and safety potentials of the methanol extract of C. pinnata in rats.  Methods: The methanol extract of C. pinnata was administered to the rats orally once daily at a dose of 0, 150, 300 or 600 mg/kg, body weight for 21 days. The toxicity was assessed using mortality rate, clinical signs, body and organ weights, hematological and serum chemistry indices. Results: The extract at 150, 300 or 600 mg/kg significantly decreased (p<0.05) the serum alanine aminotransferase and sodium, but increased the urea concentration compared with those in the controls. There were no significant treatment-related alterations in the activities of aspartate aminotransferase, albumin, bilirubin, total proteins, chloride and creatinine. Also, the serum hematological parameters including Hemoglobin (HB), Packed Cell Volume (PCV), Mean Corpuscular Hemoglobin (MCH), Mean Corpuscular Hemoglobin Concentrations (MCHC) and Red Blood Cell (RBC) did not change significantly (p<0.05). However, there were significant increases (p<0.05) in White Blood Cell (WBC) and platelet counts, in weight gain and relative liver, kidney, lung and heart body weight ratio in the rats treated with 600 mg/kg of the extract compared with those in the controls.  Conclusion: The C. pinnata extract was safe and non-toxic to the rats’ liver and blood components at doses up to 600 mg/kg for a period of 21 days. However, alterations found in the markers of kidneys integrity call for exercising caution when using this extract orally as a long-term remedy.
