The total number of white blood cells (WBCs) is related the immune system. In mammals, it is affected by the body mass, but it is unclear how the numbers of different WBC types correlate with this parameter. We analyzed the effect of body mass on WBC number and ratio in felids, where species are similar in diet (warm-blood vertebrates) and reproductive strategy (promiscuity). Based on zoo veterinary data (ZIMS database) we analyzed the effect of body mass on WBC number and neutrophils/lymphocytes ratio in 26 species of felids. The number of WBCs correlated with the body masses of animals: large cats had more WBC, which may be due to greater risks of infection associated with larger body surface, lifespan and home range size. For the first time we found obvious differences in the number of WBC types. Large cats also had more neutrophils and monocytes but fewer lymphocytes than smaller cats. The ratio of neutrophils to lymphocytes is greater in large felids. This phenomenon may be related to diet (relative prey size and kill utilization time), which suggests regular contact of large cats with bacterial and protozoal pathogens in contrast to the small cats.

Edema Factor

The anthrax toxin comprises three proteins. When they work together, they can kill humans, especially after spores of the bacteria have been inhaled. One anthrax protein, called protective antigen (PA), chaperones the two other toxins into human or animal cells and shields them from the body’s immune system. The second, lethal factor (LF), destroys the white blood cells that hosts send in defence. The third toxin molecule, edema factor (EF), hijacks the signaling system in the body. This disrupts the energy balance of cells and leads to them accumulating fluid and complete destroy of cells.

This research was conducted to estimate the effects of Persicaria odorata leaf meal (POLM) on haematological indices, serum biochemical attributes, and internal organs parameters, including histomorphological features of the liver, in broiler chickens. A total of 120 one-day-old male broiler chicks (Cobb-500) were randomly allocated into four experimental groups. The dietary treatments were basal diet (BD), which served as the control (C), along with BD + 2 g/kg POLM (Po2), BD + 4 g/kg POLM (Po4), BD + 8 g/kg POLM (Po8), which were the supplemented groups. The body weight gain (BWG) showed a linear increase and feed conversion ratio (FCR) showed a linear decrease with increasing POLM dosage at day 42 (p ˂ 0.05) and for the overall growth performance period (p ˂ 0.01). On day 21 and day 42, the values of red blood cells (RBCs), white blood cells (WBCs), haemoglobin (Hb), and packed cell volume (PCV) showed linear increases (p ˂0.05) as the dosage of POLM increased in the diet. On day 21, dietary supplementation of POLM linearly decreased (p ˂ 0.05) the serum activity of alkaline phosphatase (ALP), aspartate aminotransaminase (AST), alanine aminotransaminase (ALT), and serum levels of urea and creatinine. On the other hand, serum levels of total protein (TP), albumin, and globulin showed a linear increase (p ˂ 0.05) as the POLM dosage increased. On day 42, the serum activity of AST and ALT and serum levels of glucose, cholesterol, triglycerides, urea, and creatinine showed linear decreases (p ˂ 0.05) with increased levels of POLM in the diet. However, POLM supplementation linearly increased (p ˂ 0.05) the serum levels of TP and globulin. Dietary inclusion of POLM did not influence the organ parameters and showed no adverse effects on the liver histomorphology. In conclusion, supplementation of POLM increased the growth performance, improving haematological indices and serum biochemistry profiles of broiler chickens without any deleterious effects on the liver histomorphology. The results of the present study provide evidence that POLM can be safely used at a dose rate of 8 g/kg of feed as an alternative to conventional antimicrobial growth promoters (AGPs).

Purpose The elevated white blood cells (WBCs) count has been reported to be a predictor of cardiovascular diseases, diabetes, hypertension and metabolic syndrome. This study aims to determine the associations between WBCs count and obesity in apparently healthy young adults. Design/methodology/approach In this cross-sectional study, the authors evaluated the body mass index (BMI) in 392 apparently healthy young adults of both sexes. The WBCs count was measured using standard counter techniques. The inclusion criteria were the agreement to participate in the study, between 18 and 25 years of age, lack of self-reported diseases such as cardiovascular diseases, hypertension, kidney and infectious diseases. Findings According to the BMI classification, underweight and overweight or obesity were observed in 14.58 and 11.48 per cent of young adults, respectively. The mean WBC was 6.5 ± 1.5 (×10³ cells/µL). Higher values of WBCs were found in women than in men (p = 0.02). The young adults with higher BMI had a higher WBCs count. There was a positive correlation between WBCs count and weight and BMI (r = 0.19 and r = 0.22, p < 0.001, respectively). Research limitations/implications This research was a cross-sectional study. Future studies are suggested using longitudinal studies to examine more relationships between obesity and WBCs count in apparently healthy young adults. Practical implications The results of this study provide evidence for weight management in this age group to reduce diseases associated with increased WBCs count. Originality/value The WBCs count was related to increasing levels of BMI per cent 2 C even in the normal range.

Abstract Bone marrow (BM) constitutes one of the largest organs in mice and humans, continuously generating, in a highly regulated manner, red blood cells, platelets, and white blood cells that together form the majority of cells of the body. In this review, we provide a quantitative overview of BM cellular composition, we summarize emerging knowledge on its structural organization and cellular niches, and we argue for the need of multidimensional approaches such as recently developed imaging techniques to uncover the complex spatial logic that underlies BM function in health and disease.

To date, the search for the most informa-tive and simple methods for diagnose of adaptive capabilities is an urgent problem of veterinary medicine and adaptive physiolo-gy. The direction of the animal body's re-sponse to the hypoxic factor has not been sufficiently studied. Objective: the analyze of the dynamics of changes of the main indi-cators in the leukogram under the influence of hypoxia, as well as the study of the role of leukocyte, indices the analysis of the level of resistance in rats. The animals were divided into two groups: in the first case, the animals were injected with cytoflavin at a dose of 135 mg/kg before the hypoxia ses-sion, and in the second case, saline was ad-ministered at an equivalent dose. The blood test was performed on a hematological auto-matic analyzer, and the clinical parameters of peripheral blood were determined. Mathe-matically, the leukogram was used to deter-mine: the white blood cell shift index (ISLC), the lymphocyte-monocyte ratio in-dex (ISLM), and the lymphocyte-granulocyte index (ILG). The results of the study showed that the course of hypoxia contributes to a number of changes in the blood composition, for 21 days. There was an increase in the number of white blood cells in both groups, a change in the parame-ters of the leukocyte formula-a decrease in the content of lymphocytes, with a simulta-neous increase in the proportion of mono-cytes. The use of interval hypoxia caused a decrease in the content of red blood cells in animals of the first group, a decrease in the concentration of hemoglobin and hematocrit in both groups studied. The number of plate-lets increased, which also indicates the start of adaptive reactions in the body of rats. The use of leukocyte indices is the assess to the level of resistance of the body and showed their high significance and informa-tive value in modeling experimental hypoxia.

The catalytic activity of the blood of normal rabbits varies almost directly with the volume and number of red blood cells. This explains to a certain extent at least why animals of the same general degree of nutrition, and of the same litter, should have about the same activity since they are likely to have the same number of red blood cells, and why healthy large animals should read high while small poorly nourished ones should read low. Accompanying the hyperpyrexia resulting from puncture of the corpus striatum of a rabbit's brain, there is no change in either the catalytic activity of the blood or the white blood count. In experimentally produced peritonitis, the catalytic activity of the blood always rises, and is, therefore, absolutely independent of body temperature and white blood cells since one or both of these may rise, fall or remain stationary while the catalytic action increases.

RBC (Red Blood Cells) and WBC (White Blood Cells) are the main constituents of blood. WBC fight infections by attacking bacteria and viruses, that invade the body, while RBC transports oxygen in the body. Many blood diseases can be detected using RBC and WBC count values. Immunity-related blood diseases like Leukopenia and Leukocytosis can be easily detected using the WBC count value. The manual counting method of blood cells in laboratories takes at least one day to get the blood results, which becomes a major drawback for healthcare sectors to diagnose the disease at the right time. More expensive pathological tests are also a major drawback. Accurate counting of blood cells is essential in the accurate diagnosis of the disease. The proposed system is used to calculate the RBC and WBC Count, Total blood Count, RBC and percentage and the blood disease (Leukocytosis, Leukopenia) from the input blood smear image. This will help laboratories to perform the counting of blood cells with high accuracy and less workload. This is achieved by pre-processing that involves grayscale conversion, image enhancement, noise removal, binary conversion of input image, followed by plane extraction and threshold-based Segmentation. The blood disease (Leukocytosis and Leukopenia) is detected using WBC percentage-based classification methodology. This approach obtained an accuracy of 98.4%, specificity of 88.889%, precision of 99.58%, F - Measure of 99.50%. Morphological operations are implemented using MATLAB software.
