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.

The maternal body must adapt to fetal growth and development during the state of pregnancy for successful foal and mother. Pregnancy status as in other mammals is related to physiology and hematology. This study aimed to compare the hematology profiles and biochemical parameters of late pregnant and non-pregnant mares. Twenty-two mares were included in the study. Mares were divided into two groups according to the pregnancy status. Hematology profile and biochemical parameters were analyzed from blood samples collected from the jugular vein. All data were analyzed using Stata 12/MP4. White blood cell count, lymphocyte, red blood cell count, hemoglobin concentration, hematocrit, monocyte and percentage of monocyte were significantly lower in non-pregnant mares compared to late pregnant mares (P<0.05). No significant differences were noted in values of neutrophil, eosinophil, mean cell volume, mean corpuscular hemoglobin concentration, mean corpuscular hemoglobin, platelet, mean platelet volume, red cell distribution width in both groups (P>0.05). On the other hand, biochemical parameters analysis showed that calcium, total bilirubin, and triglyceride concentrations were greater in late pregnant mares (P<0.05). However, urea, albumin, cholesterol, and magnesium concentrations were similar among groups (P>0.05). In conclusion, the present study showed hematology profile and biochemical parameters differences in late pregnant and non-pregnant mares. These values could be useful in clinical practices to assess the situation of late pregnant mares.

Hematological results are reported for 13 giant anteaters (Myrmecophaga tridactyla) and 13 collared anteaters (Tamandua tetradactyla). Animals were captive-reared adults held at the Fundação Parque Zoológico de São Paulo (São Paulo, SP, Brazil) and Parque Zoológico Municipal Quinzinho de Barros (Sorocaba, SP, Brazil), and were considered healthy on physical examination. Examined parameters included red blood cell count, white blood cell count, hematocrit, hemoglobin concentration, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, total plasmatic protein and differential leukocyte counts. Also, a survey for hemoparasites was done and none was observed in thin blood smears. The results were generally similar to those previously reported in the exiguous literature for these species, providing further reference data for the interpretation of laboratory results besides health monitoring, assisting early disease diagnosis and providing relevant information for conservation programs for these species.

Although proper exercise training induces positive physiological effects, improper exercise can lead to injury, fatigue, and poor performance. The frequency, intensity, time/duration, type, volume, and progression (FITT-VP) are the essential components of exercise training to maintain or improve physical fitness and health. The purpose of this study was to develop specific exercise programs by applying the FITT-VP principle and to examine the effects on heart rate (HR) and hematological and biochemical parameters in dogs. The healthy male Beagles (n = 4) included in this study performed continuous and interval exercises, comprising 12 protocols. The HR monitoring elicited an affirmative response to activities but varied depending on the protocols. The hematologic parameters (e.g., red blood cell count, white blood cell count, hemoglobin, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration) were within the reference ranges both before and after exercise. The creatine kinase level significantly increased, and the cholesterol level decreased after exercises. In conclusion, the continuous and interval exercise program elicits an appropriate HR reaction, has no adverse effects on the serum parameters, and provides valuable insight for healthcare in dogs.

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.

Eleginops maclovinus has been an important fishery resource in Chile since 1957. Caligus rogercresseyi is one of the most prevalent ectoparasite species found on E. maclovinus. Hematocrit, hemoglobin level, red blood cell count (RBC), white blood cell count (WBC), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC) and differential white blood cell count were determined before and after an experimental infestation withC. rogercresseyi. We found significant differences in the hemoglobin level, WBC, MCV, MCH, MCHC, hematocrit level and RBC between infested and uninfested fish. Furthermore correlations between number of C. rogercresseyi with hematocrit, MCHC, neutrophil, eosinophil and lymphocyte counts were found. Hematological reference ranges of E. maclovinus in captivity conditions were also established.

Abstract Complete blood cell counts have been used as a diagnostic tool across many animal species including swine. To investigate the factors that cause variation in complete blood cell count results, a total of 2,284 whole blood samples were collected from 2012 to 2019 in preweaning piglets (n = 518), nursery pigs (n = 1,704), and grower pigs (n = 60). Whole blood was collected into K2EDTA blood collection tubes and assayed using an automatic hematologic analyzer within 6 hours of collection. Data were analyzed by Mixed procedure of SAS with gender, parity group, and farrowing season as fixed effects. Body weight and age of pigs served as covariances. Farrowing season was grouped into summer (born during May to October) or winter (or November to April). Pigs that were born from first, second, and third parity, and four and above parity sows were assorted into parity group 1, 2 to 3, and 4+, respectively. Barrows had a greater concentration of total white blood cells (P &lt; 0.01), lymphocytes (P &lt; 0.01), and neutrophils (P &lt; 0.01) compared to gilts. Barrows had lower mean corpuscular volume (P = 0.03), mean corpuscular hemoglobin (P &lt; 0.01), and mean corpuscular hemoglobin concentration (P = 0.02) compared to gilts. Pigs that were farrowed in the winter season had a greater concentration of white blood cells (P = 0.01), neutrophils (P = 0.01), and the percentage of neutrophils (P = 0.03), but were lower in the percentage of lymphocytes (P = 0.03) compared to pigs farrowed during summer. Pigs born to parity four and above sows obtained a greater lymphocyte count (P = 0.01), percentage of neutrophils (P = 0.02), and percentage of lymphocytes (P = 0.01). We concluded that peripheral complete blood cells count results were affected by gender, farrowing season, and sow parity.

Background: During viral outbreaks, pregnancy poses an increased risk of infection for women. Methods: In a prospective study, all patients admitted for delivery at term to Elena Doamna Obstetrics and Gynecology University Hospital in Iasi, Romania, between 1 April 2020 and 31 December 2020 were included. There were 457 patients, divided into two groups: group 1, SARS-CoV-2-positive patients (n = 46) and group 2, SARS-CoV-2-negative patients (n = 411). Among other tests, complete blood count was determined upon admittance, and the following values were studied: white blood cell count, lymphocytes, neutrophils, red blood cell count, hemoglobin, mean corpuscular hemoglobin concentration, mean corpuscular hemoglobin, mean corpuscular volume, red blood cell distribution width, hematocrit, platelet count, mean platelet volume, platelet distribution width, plateletcrit, and platelet large cell ratio. Results: in pregnant SARS-CoV-2-infected patients at term, there was a significant decrease in white blood cell, neutrophil, and lymphocyte count, and an increase in mean corpuscular hemoglobin concentration, compared to healthy pregnant women at term, although all still within normal limits. None of the other components of the complete blood count or fetal outcomes studied was significantly influenced by SARS-CoV-2 infection in pregnant patients at term.

     This study was designed to determine the effect of ketorolac on some hematological parameters post cavitation surgery in domestic rabbits. Ninety-six adult domestic local breed male rabbits were used in this study, weighing (1.23 ± 0.33) kg. They were divided randomly into two groups in the first one (n= 48/group) which represented control group, while the second one (n=48/group) represented the treated group (Ketorolac group). All rabbits in both groups undergoes surgical operation (bone cavitation in femur bone) under general anesthesia. In the Ketorolac group, animals were treated by using 30 mg/kg of Ketorolac directly post-operation and continued daily for 5 days, while in Control group no treatment was given postoperatively. The hematological parameters were recorded which include white blood cells count; red blood cells count; hemoglobin; packed cell volume; mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration; mean corpuscular volume and platelets at the period of (3, 5, 7, 14, 21, 28, 35, and 42) days post operation were estimated. Results concerning hematological values showed no significant differences in packed cell volume values between control and treated group and within each group, while haemoglobin values showed a significant decrease at period 7 and 14 days between control and treated group. Within control group the significant decrease were noticed clearly at period of 7 days. Data concerning mean corpuscular hemoglobin values within control group showed significant decrease were noticed at 5 day, but within treated group, there were no significant differences. mean corpuscular hemoglobin concentration values showed significant decrease ate period 3; 5 and 21 days between control group and treated group respectively. Within control group the significant decrease were noticed obviously at 5 days while within treated group the significant decrease were noticed at 35 days. mean corpuscular volume values showed significant increase at 3 and 5 days period between control and treated groups. Platelets counts within control group showed significant increase at period of 14 days, within treated group the significant increase were recorded at 42 days. Red blood cells showed significant decrease between control and treated groups, while within control group, the significant decrease were at 7 days. White blood cells count within treated group showed significant increase recorded at 21 days. Differential White blood cells count concerning Lymphocytes cells within control group the significant increase were recorded at 42 days  while the significant decrease were noticed at 21 days, but within treated group the significant increase were recorded at 35 days  and significant decrease were noticed at 14 days. Neutrophils counts showed significant decrease at periods 3, 14, 28 and 42 days between control and treated groups respectively; while within control group there were significant decrease at 3 days, but within treated group the significant decrease were noticed at 42 days.
