After racing 722 m, 16 Greyhounds were evaluated to determine changes in hematologic, biochemical, blood-gas, and acid-base values following exercise. Values were determined before racing (T(0)), immediately after racing (T(1)), and 3 hours after racing (T(2)). Significant changes detected immediately after racing included heart rate, respiratory rate, and rectal temperature. Significant changes in hematologic values included increases in PCV, total plasma protein, hemoglobin, RBC, WBC, neutrophils, and lymphocytes. Change was not detected in values for monocytes, eosinophils, and neutrophil/lymphocyte ratio. Other increases included those for plasma concentrations of sodium, chloride, calcium, lactic acid, aspartate transaminase, alanine transaminase, alkaline phosphatase, creatine kinase, lactate dehydrogenase, and glucose. Concentrations of potassium and urea did not change. Measurement of blood-gas and acid-base status revealed significant increases in Pao2 and base deficit, whereas Paco2, pH, and bicarbonate decreased. Three hours after exercise, all vital signs and blood-gas and acid-base values, except for Paco2, which was still slightly, low, had returned to baseline (T(0)) values. Most biochemical values had also returned to baseline, although sodium, chloride, asparatate transaminase, and creatine kinase were still high, and urea was low. Many hematologic values were still different from baseline values, with high values for WBC, neutrophils and neutrophil/lymphocyte ratio, and low values for PCV, total plasma protein, hemoglobin, RBC, and lymphocytes.

The influence of immunosuppression by T-2 mycotoxin on the fungal disease aspergillosis was investigated in rabbits. Four groups of rabbits (groups 1A, 1B, 3A, and 3B) were given 0.5 mg of T-2 toxin/kg of body weight/day, PO; in addition, rabbits of groups 3A and 3B were exposed to aerosols of Aspergillus fumigatus conidia from days 7 through 16. Rabbits of groups 2A and 2B were exposed to A fumigatus aerosols, but were not given T-2 toxin, and rabbits of group 0 served as controls. Two rabbits of group 1A, 1 rabbit of group 1B, and 1 rabbit of group 3A died before scheduled necropsy. Rabbits of groups 1A, 2A and 3A were killed and necropsied on day 17, and the remaining rabbits (groups 0, 1B, 2B, and 3B) were killed and necropsied on day 28. Changes caused by T-2 toxin included leukopenia, marginal anemia, and increased number of and morphologic changes in nucleated erythrocytes by day 21, followed by a regenerative hematologic response. Serum alkaline phosphatase and sorbitol dehydrogenase activities and antibody response to A fumigatus (as measuredby an indirect hemagglutination test) were decreased by T-2 toxin ingestion. Rabbits with aspergillosis had leukocytosis, increased PCV, and increased antibody response to A fumigatus. Histologic lesions consisting of centrilobular hepatocellular swelling, portal and periportal fibrosis, and lymphocyte necrosis and/or depletion within secondary lymphoid tissue were observed in most rabbits treated with T-2 toxin. Normal defense mechanisms against A fumigatus infection were compromised by T-2 treatment, as evidenced by the severity and extent of lung lesions, greater number of hyphal elements observed, and greater number of colonies of A fumigatus isolated from rabbits of groups 3A and 3B. There were no significant changes in group-0 rabbits.

To estimate the source of variance components for some hematological parameters and assess the utility of the conventional population-based reference interval, this study computed index of individuality for blood samples, which were from 13 dogs drawn once weekly for 4 consecutive weeks. Results were subjected to nested analysis of variance. For all parameters measured between-dog variations were greater than within-dog variation. Except for the parameters RBC and MCHC the index of individuality was less than 1.4. The low reliability coefficient and high index of individuality of less-than or equal to 0.8 were found for the majority of hematological parameters.

The blood is a connective tissue that composes of suspended cells in liquidmatrix. In this study ,we discuss the effect of three factors on blood sampling duringthe collection of blood samples (anti-coagulants, temperature and duration of storage). The delay of storage processing led to hemolysis of blood sample , increase ofhemoglobin, decrease of red cells ,triglycerides, hematocrite, mean corpuscularvolume, mean corpuscular hemoglobin and its concentration and increase number ofwhite blood cells. The histological analysis of blood sample during long-term storageshowed a slight difference in the shape and size of RBC,WBC and platelets as well ascondensed nucleus bluish cytoplasm and basophilic segmented nucleus in neutrophilsin addition to decrease in sodium ,calcium and chloride. The effect of temperature onblood sampling showed slight variation in shape and size of RBC , basophilicneutrophils and platelets aggregation and decrease of leukocyte number and K levels .

The effect of quercetin derivative (1-(-2-(3,4-dihydroxyphenyl)-3,5,7-trihydroxy-4 H –chromen-4-ylidene) thiourea coded (QTU)  on the hematological profile of Wistar rats induced toxicity with carbon tetrachloride (CCl4) was investigated. Administration intraperitoneal injection of 12.5 mg /kg and 25mg/kg of quercetin derivative (QTU), after four weeks of being exposed to CCl4, led to a  significant decrease  (p<0.05) in WBC count, with a corresponding increase on PCV and Hb. It was also observed that the functional recovery of these blood indices is concentration dependent.  Results of this study revealed a depletion of RBC and a decrease in Packed Cell Volume (PCV) and Hemoglobin (Hb), In addition, an elevation in the levels of White Blood Cell (WBC) caused by CCl4 compared to control samples. 

The current study aims to evaluate the effect of Iraqi sweet almond (Prunus amygdalus) on the toxicity of lead acetate in wild pigeons Rock Doves (Columba livia gaddi) on body weight and certain hematological and biochemical parameters. Forty healthy adults of both sexes Rock Dove pigeons were randomly selected and categorized into four groups, A,B,C, and D. Group A (control group), were fed on a balanced ration, group B, were administered lead acetate 72 mg/kg body weight orally, group C orally administered with an aqueous extract of Iraqi sweet almond (Prunus amygdalus) 300 mg/kg body weight, and group D were orally administered with 72 mg/kg body weight of lead acetate and 300 mg/kg body weight of the  aqueous extract of Iraqi sweet almond (Prunus amygdalus). These materials were administered daily and for the whole study period which extended to 28 days. Results showed that lead acetate alone caused significant decrease (P≤ 0.05) in the body weight, hemoglobin concentration, total erythrocyte count, PCV% and triglycerides, while there were a significant increase (P≤ 0.05) in total leukocyte count, heterophils, monocytes, lymphocytes, glucose, uric acid, and AST and ALT activities. On the other hand, combined treatment with Iraqi sweet almond and lead acetate to members of group (D) caused significant increase (P≤ 0.05) in hemoglobin, total erythrocyte count, PCV% and lymphocytes, and  significant decrease (P≤ 0.05) in cholesterol and uric acid, while no significant differences in triglyceride and AST and ALT activities. The present finding concludes that adding of Iraqi sweet almond has significant effects on certain hematological and biochemical properties of Rock Dove pigeons (Columba livia gaddi) affected by administering lead.

The study of alterations of some hematological parameters in a experimentally induced lead toxicosis were carried out on a total of 15 (15 days old) male weaning Long- Evans (ICDDRB strain) rats. The rats were randomly divided in to three equal groups, each consisting of fiverats. Rats of group A were kept as control (without giving any treatment), group B received lead acetate alone @ 6 mg/ml drinking water and group C receivedlead acetate @ 6 mg/ml plus whole milk (Star ship®) 150 mg/ml drinking water. The result showed a most significantly (p< 0.01) decreased TEC, TLC and Hb%observed on day 56 in group B but in group C, these counts decreased significantly (p< 0.05) on days 56 of experiment. From the study, it was concluded that treatment with lead acetate at low doses has harmfuleffects on experimental animals including hematological alterations.

This study was conducted to investigate the effects of adding raw garlic in the diets on certain hematological and serum biochemistry of broiler chicken. Total of (40) birds (one day old) were used for this study. The birds divided randomly and equally into (4) treatment groups which fed on one of the following for 56 days: group (1) was fed on 10% raw garlic with basal diet, group (2) was fed on 5% raw garlic with basal diet, group (3) fed on basal diet and antibiotic (Ampicillin) which was added to the drinking water and group (4) fed on basal diet only (control group) The results showed that there were no significant alteration in PCV and RBCs in the group which fed on 10% raw garlic compared with the control one, however these group showed significant (p

Aflatoxin (AF)-contaminated and fumonisin B1 (FB1)-contaminated (culture material from Fusarium moniliforme) diets were fed singly and in combination to growing cross-bred barrows. Six barrows (3 replicates of 2 each; mean body weight, 17.5 kg) per group were fed: 0 mg of AF and 0 mg of FB1/kg of feed (control); 2.5 mg of AF/kg of feed; 100 mg of FB1/kg of feed; or 2.5 mg of AF plus 100 mg of FB1/kg of feed for 35 days. The effects on production performance, serum biochemical, hematologic, immunologic, and pathologic measurements were evaluated. Body weight, gain, and feed consumption were significantly (P < 0.05) decreased by AF and AF plus FB1 diets. The FB1 diet decreased feed consumption, and although body weight was numerically decreased, it was not statistically significant. Aflatoxin increased serum gamma-glutamyltransferase (GGT) activity and total iron concentration and decreased urea nitrogen concentration and unsaturated iron-binding capacity. The FB1-alone diet increased serum GGT activity, whereas the AF plus FB1 diet increased serum aspartate transaminase, cholinesterase, alkaline phosphatase, and GGT activities, increased RBC count, triglycerides, and total iron concentrations, and decreased unsaturated iron-binding capacity and urea nitrogen concentration. For the most part, the effects of the AF plus FB1 diet on body weight and hematologic measurements could be considered additive. However, the effect of the AF plus FB1 diet on cholinesterase and alkaline phosphatase activities was greater than additive and was a synergistic response. One pig in the FB1-diet group and 2 pigs in the combination-diet group died. Postmortem lesions in pigs of the FB1-diet group consisted of ascites and increased liver weight. Observations at necropsy for pigs of the AF plus FB1-diet group consisted of hydrothorax, ascites, pulmonary edema, gastric erosions and ulceration, and increased liver and spleen weights. The AF diet increased relative liver weight and resulted in liver that was pale, rubbery, and resistant to cutting. Histologic lesions consisted of hepatic necrosis or degeneration, or both, with variable degrees of bile duct proliferation in barrows of the AF-diet groups. Renal tubular nephrosis was observed in barrows of the FB1 diet group, but this was not consistent in the AF plus FB1-diet group. Cell-mediated immunity, as measured by mitogen-induced lymphoblastogenic stimulation index, was decreased in barrows of the AF and FB1-diet groups, and values in barrows given the combination diet were significantly decreased from those in barrows given the single toxin diets. It was concluded that AF and FB1 (from culture material), singly or in combination, can adversely affect clinical performance, serum biochemical, hematologic, and immunologic values and induce lesions in growing barrows. For most of the variables we evaluated under our study conditions and dosages of toxins, measurements were affected more by the combination diet than by either single toxin diet, and the toxic responses could be described as additive or more than additive, particularly for induction of liver disease.

Effects of dietary ochratoxin A (OA) and T-2 toxin, fed singly and in combination, were evaluated in growing crossbred pigs. Thirty-six barrows (3 replicates of 3 for each of 4 treatment groups, mean body weight, 18.0 kg) were fed: 0 mg of OA and 0 mg of T-2/kg of feed (control); 2.5 mg of OA/kg of feed; 8.0 mg of T-2/kg of feed; or 2.5 mg of OA plus 8.0 mg of T-2/kg of feed for 30 days. Production performance, serum biochemical, hematologic, immunologic, and pathologic evaluations were made. Body weight and body weight gain were decreased by all toxin treatments, but the combination toxin treatment reduced weight gain more than did either of the toxins administered singly and could be considered additive. Liver weight was decreased by combination treatment, whereas kidney weight was increased by OA treatment. Ochratoxin decreased serum cholesterol, inorganic phosphorus, and alkaline phosphatase values; reduced mean cell volume, hemoglobin concentration, and macrophage phagocytosis; and increased creatinine and total protein values. Consumption of T-2 toxin reduced hemoglobin and serum alkaline phosphatase values. The combination treatment decreased serum cholesterol, gamma-glutamyltransferase, alkaline phosphatase, mean cell volume, hematocrit, and hemoglobin values, as well as lymphoblastogenesis and phagocytosis, and increased serum nine concentration. We concluded that OA and T-2, singly or in combination, can affect clinical performance, serum biochemical, hematologic, and immunologic values, and organ weights of growing barrows. Although some analytes were affected more by the combination than by either toxin alone, the interactions could best be described as additive, not synergistic.
