Abstract Background This study was undertaken to compare the sensitivities of mice strains during tumor induction by transcription activator-like effector nucleases (TALEN)-mediated Trp53 mutant gene. Alterations of their tumorigenic phenotypes including survival rate, tumor formation and tumor spectrum, were assessed in FVB/N-Trp53em2Hwl/Korl and C57BL/6-Trp53em1Hwl/Korl knockout (KO) mice over 16 weeks. Results Most of the physiological phenotypes factors were observed to be higher in FVB/N-Trp53em2Hwl/Korl KO mice than C57BL/6-Trp53em1Hwl/Korl KO mice, although there were significant differences in the body weight, immune organ weight, number of red blood cells, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), platelet count (PLT), total bilirubin (Bil-T) and glucose (Glu) levels in the KO mice relative to the wild type (WT) mice. Furthermore, numerous solid tumors were also observed in various regions of the surface skin of FVB/N-Trp53em2Hwl/Korl KO mice, but were not detected in C57BL/6-Trp53em1Hwl/Korl KO mice. The most frequently observed tumor in both the Trp53 KO mice was malignant lymphoma, while soft tissue teratomas and hemangiosarcomas were only detected in the FVB/N-Trp53em2Hwl/Korl KO mice. Conclusions Our results indicate that the spectrum and incidence of tumors induced by the TALEN-mediated Trp53 mutant gene is greater in FVB/N-Trp53em2Hwl/Korl KO mice than C57BL/6-Trp53em1Hwl/Korl KO mice over 16 weeks.

Abstract Among Kinetoplastida, the Trypanosoma is the genus with the highest occurrence infecting populations of marine fish and freshwater in the world, with high levels of prevalence, causing influences fish health and consequent economic losses, mainly for fish populations in situation stress. This study investigated infections of Hypostomus spp. by Trypanosoma spp. and leeches, as well as blood parameters of this host in the network of tributaries of the Tapajós River in the state of Pará, in the eastern Amazon region in Brazil. Of the 47 hosts examined, 89.4% were parasitized by Trypanosoma spp. and 55.4% also had leeches attached around the mouth. The intensity of Trypanosoma spp. increased with the size of the host, but the body conditions were not influenced by the parasitism. The number of red blood cells, and hemoglobin, mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), mean corpuscular hemoglobin (MCH), total number of leukocytes and thrombocytes showed variations and negative correlation with the intensity of Trypanosoma spp. in the blood of the hosts. The results suggest that the leeches were vectors of Trypanosoma spp. in Hypostomus spp.

The influence of the physiological state of rabbits (pregnancy and lactation) on the hematological parameters of blood during changes in the area of the plantar surface of the feet of the hind limbs in conditions of cage keeping was studied. In the body of pregnant females, with the appearance of signs of hyperkeratosis and alopecia in the studied area of the feet, an increase in hemoglobin level occurs, an increase in MCH (mean corpuscular hemoglobin), MCV (Mean Corpuscular Volume), MCHC (corpuscular hemoglobin concentration) occurs, followed by a decrease in the development of hemorrhagic changes. The level of red blood cells has slight fluctuations. In lactating females, with the occurrence of alopecia and hyperkeratosis, an increase in the level of erythrocytes and hematocrit occurs with a simultaneous decrease in hemoglobin, and against the background of the development of hemorrhages, these indicators decrease, a decline in the values of MCH, MCHS and an increase in MCV are recorded. Regardless of the physiological state of the animal and changes in the area of the feet, the erythrocyte sedimentation rate (ESR) value and the level of leukocytes fluctuate within the limits of physiological values, which indicates the absence of an inflammatory process in the body. he revealed hematological changes indicate the development of adaptive processes in the event of hyperkeratosis and alopecia in the area of the plantar surface of the feet at various physiological conditions of rabbits with subsequent decompensating against the background of hemorrhagic changes.

Abstract Because we recently observed two patients with severe diabetic hyperglycemia and spuriously elevated electronically determined hematocrit and mean corpuscular volume (MCV), we investigated the effect of hyperglycemia on two popular automated hematology systems, the Coulter S and Ortho ELT-8. Marked hyperglycemia (blood glucose 800-- 2000 mg/dl) caused consistent overestimation of the electronically determined MCV compared to that derived from a simultaneous spun microhematocrit. The resultant overestimation and underestimation, respectively, of the derived values for hematocrit and mean corpuscular hemoglobin concentration may be clinically misleading. The mechanism of MCV elevation in hyperglycemia appears to be swelling of hyperosmolar glucose “loaded” erythrocytes when diluted into “isotonic” counting medium. This effect is readily circumvented by determination of a spun microhematocrit.

Abstract Developments of pulmonary diseases, often accompanied by infections of bacteria, severely affect the meat production and welfare of pigs. This study investigated 307 pigs at age of 240 d from an eight-breed cross reared under standardized housing conditions for associations among the extent of lung lesions, bacteria load inferred from 16S rRNA sequencing of bronchoalveolar lavage fluid, as well as 57 immune cells and 25 hematological traits. We showed that the pigs under study suffered substantial and varied lung lesions, and the Mycoplasma is the most associated bacteria genera. At a false discovery rate of 0.05 (FDR &lt; 0.05), the severity of lung lesions were significantly associated with greater CD8+ to CD3+ cell ratio, neutrophil-to-lymphocyte ratio (NLR), and standard deviation of red blood cell volume distribution width (RDW-SD), and lower CD4−CD8−/CD3+, CD3+CD4−CD8−/PBMCs (peripheral blood mononuclear cells) and CD14−CD16−/PBMCs cell ratios, mean corpuscular hemoglobin concentration, lymphocyte count, and lymphocyte count percentage, reflecting an status of inflammation, immune suppression, and hypoxia of the pigs accompanying the progression of the lung lesions. The Mycoplasma abundance showed positive correlations with neutrophil count, neutrophil count percentage, NLR, monocyte count, coefficient of variation in red blood cell volume distribution width , and RDW-SD, and negative correlations with mean corpuscular hemoglobin concentration, lymphocyte count, and lymphocyte count percentage; these correlations are largely consistent with those of lung lesions, supporting the comorbidity of lung lesions and Mycoplasma infection. We also observed nonlinear associations that sharp increases in neutrophil count and neutrophil count percentage occurred only when Mycoplasma abundance raised above the population-average level. The results provide helpful insights into the changes of host immune status in response to Mycoplasma relevant lung diseases in pigs.

Thalassemia is common inherited disorder among humans, and they represent a major public health problem in many areas of the world. The study aimed to the measurement of hematological characterization of beta-thalassemia in Sudanese patients. Blood samples from 61 beta-thalassemic patients were collected after written consent form obtained from all participants. The frequency of adults (>18 years) was 45 (73.8%) and children’s (<18 years) was 16 (26.2%); the frequency of male was 27 (44.3%) and 34 were female (55.7%). Hemoglobin estimation and red cell indices were carried out using the automatic blood cell counter Sysmex K × 21N. The results showed that Hb and RBCs indices were varied between mild to moderate and severe decreasing, hemoglobin concentration (Hb) with the mean value of 9.6 g/dL, with minimum value of 6.1 g/dl and maximum of 11.9 g/dl, while RBCs were increased in all patients, mean value 5.2 c/l, mean corpuscular volume mean was 58.9 fl, hematocrit was 30.4, mean corpuscular hemoglobin (MCH) 18.8 pg, mean corpuscular hemoglobin concentration (MCHC) was 31.7pg, and RDW was 18.8%. The method used for hemoglobin electrophoresis was capillary electrophoresis, Hb pattern shows increased HbA2 and HbF, the mean of HbA is 78.3%, HbF is 2.3%, and HbA2 is 6.5% with the min. value of 3.6% and max. of 12.2%. While the mean of serum iron was 82.75 μg/dl, 7 patients showed low level, 19 high level, and 35 were normal level. Comparison of hematological analysis (HbA2) in thalassemic patients coexisted with iron deficiency and without result was insignificant difference (p=0.645), this result disagrees with references that say iron deficiency masking HbA2. Nevertheless, the association between HbA2 and HbF revealed a statistically significant difference (p<0.013) and HbA2 with Hb was insignificant (p=0.260).

This study aimed to evaluate the effects of heat stress on quail hematological parameters two published papers on quails in 2013 were studied, analyzed and compared. Broiler Japanese quails (Coturnix coturnix japonica) were exposed to high ambient temperature (340C, 8hr/d, 0900-1700hr) in both papers. An increase in values of red blood cells count, white blood cells count, lymphocytes, heterophils and lymphocytes (H/L) ratio, Monocytes, packed cell volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration were recorded while a lower values of heterophils, basophils, eosinophils, mean corpuscular volume and hemoglobin concentration than normal were recorded in groups exposed to heat stress (340C) on day 42 in Japanese quails (Coturnix coturnix japonica). Hemoglobin concentration was least affected. The obtained results indicated that, rearing quail birds under high environmental conditions during the fattening period has a great adverse effect on blood parameters. To help maintain Japanese quail as an essential animal model further heat stress related research on modern ways is needed.

ABSTRACT Objective: The objective was to determine the basic hematological parameters of remunerated blood donors in Benin City and to compare them with those of voluntary donors. Materials and Methods: This is a prospective study conducted in a tertiary health facility in Benin City. Pretransfusion samples were obtained from blood bags after gentle mixing and analyzed for hematological parameters. Samples were analyzed using the hematology autoanalyzer MODEL SYSMEX KN21. Result: A total of 215 samples were obtained comprising 160 remunerated (paid) and 55 voluntary donor samples. In the paid donors, the mean hemoglobin concentration (Hb) and hematocrit (HCT) 7.7±2.9 and 28.8±8.5 respectively. This was significantly lower than those of voluntary donors who had 13.9±1.2 and 42.2±3.3 with P < 0.001. The mean values of the red cell counts (RBC), white cell counts (WBC), mean cell volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) were significantly lower in paid donors as P-values were <0.001. MCV was significantly low but not compared to the other parameters as P=0.04. There was no significant difference in the platelet count. Conclusion: Paid donors in Benin City have significantly lower hematological parameters than controls.
