The aim of the study was to determine the effect of sheep’s genotype and grazing site on their hematological and redox status indicators. The experiment was carried out on sheep of the Świniarka and Uhruska breeds grazed in naturally valuable areas (xerothermic grasslands) and kept in a sheepfold. Several blood indices were determined by ABACUS Junior Vet, including the numbers of leukocytes, thrombocytes and erythrocytes, hemoglobin and procalcitonin concentrations, hematocrit, the mean red cell volume and the average hemoglobin concentration in red blood cells, the percentages of lymphocytes, monocytes and granulocytes, the degree of erythrocyte anisocytosis and the degree of variation in platelet volume. The concentrations of lipid peroxides and malonic dialdehyde, the activity of superoxide dismutase and catalase and total antioxidant potential were determined by spectrophotometric methods. The study showed that Świniarka sheep had a greater antioxidant potential and higher white blood cell counts than Uhrusian sheep. It was found that sheep’s grazing place had a significant influence on the antioxidant status and hematological indicators of their blood. An improvement in antioxidant potential and hematological blood parameters was achieved in sheep grazed in naturally valuable areas, that is, in the Stawska Góra nature reserve and on xerothermic grasslands in Gródek and Kąty, compared to sheep fed in a sheepfold

Abstract The aim of the study was to determine the effect of the perinatal period on redox status indicators in the blood of ewes before and after lambing and during lactation. The study was performed on 12 ewes of the synthetic SCP line. Blood for testing of redox parameters was collected seven times: before pregnancy, 1.5 months and 24 h before lambing, 2 and 24 h after lambing, and in the fourth and eighth weeks of lactation. The following blood indices were determined by spectrophotometry: lipid peroxides, malondialdehyde, superoxide dismutase, catalase, plasma total antioxidant capacity, uric acid, urea, bilirubin, and creatinine. The tests showed that during the perinatal period reactions are generated which lead to oxidative stress. Oxidative stress in pregnant ewes was found to increase during the period before lambing and may persist even up to weeks 4-8 of lactation.

Presented hematological indices for a stress-free selection of material from moose in the process of domestication depending on age and sex characteristics. Fluctuations in the blood parameters of moose have been established within various limits, taking into account the influence of various factors - the climatic, environmental, technological, physiological state of the animal, and age and sex characteristics. Considerable attention is paid to the selection of blood from moose, one of the most labor-intensive processes when working with them. Some tendency to fluctuations in hematological parameters in young moose has been recorded. This, possibly, is associated with a decrease in the action of colostral immunity, the formation of a specific defense of the body. Differences in blood indices in moose depending on gender were unreliable. However, in males, some of them - in terms of the content of erythrocytes, basophils, and monocytes - was higher than in females, and vice versa, in females - the number of leukocytes, lymphocytes, and eosinophils. It was shown that in young animals of 21-50 days of age, a neutrophilic profile prevails with increased content of segmented forms, and in adults - a lymphocytic profile. Compared with moose, which are in the process of domestication in animals living in natural conditions, expressed leukocytosis was recorded. As a result of the studies, the estimated norms of morphological parameters of the blood of moose in the process of domestication are established, depending on age and gender.

Farming of native carnivore fish species has drawn attention due to their promising use in aquaculture. Among these species, tucunaré of the genus Cichla stand out, them being of high economical interest for sport fishing and Amazon's industry of ornamental fish. The present study describes the weight-length relationship (WLR), relative condition factor (Kn), red blood cell parameters, thrombocytes and leukocytes count of Cichla temensis Humboldt, 1821, farmed in central Amazon. Fish that underwent food training during fingerling culture received extruded ration containing 45% of crude protein during fattening, and had Kn with values from 0.925-1.199, which indicated good health condition during the culture. The equation obtained from the WLR was W = 0.0073Lt3.1435, indicating an isometric growth, which is the desirable for fish of fish farm. Red blood cell counts, total thrombocyte and leukocyte counts, hematocrit, hemoglobin concentration, mean corpuscular volume (MCV), concentration of mean corpuscular hemoglobin (MCHC), lymphocytes, monocytes and neutrophils had intra-specific variation. A significant (p<0.001) positive correlation of the red blood cells number with the hemoglobin concentration and hematocrit was found. These are the first sets of blood parameters for C. temensis and could be used as reference for comparison in further studies to evaluate the health status of this fish in different environments, because assessment of these parameters may be used as quick tool for diagnosing diseases, stress and malnutrition.

The aim of this study was to investigate effects of lambda-cyhalothrin (LCT) on clinical, hematological, biochemical and pathological alterations in rabbits (Oryctolagus cuniculus). New Zealand white female rabbits (n = 24) of 4-5 months age having 997.92 ± 32.83 g weight were divided into four equal groups. Group A (control) received normal saline intraperitoneally (ip). Animals in groups B, C and D were treated with LCT 1.0, 4.0 and 8.0 mg/kg bw ip. Each group received seven consecutive doses at an interval of 48 hours. Blood and serum samples were collected at an interval of 96 hours. Blood analysis revealed a significant (p < 0.05) decrease in red blood cell and white blood cell counts, hemoglobin concentration and lymphocytes, while mean corpuscular hemoglobin concentration, mean corpuscular volume, neutrophils, monocytes and eosinophils were increased. Serum biochemical analysis revealed significant (p < 0.05) decrease in serum total proteins and serum albumin, while an increase was seen in serum alanine aminotransferase and aspartate aminotransferase activities compared with the control group. Serum globulin values varied non-significantly in all treatment groups as compared to control group. A dose-dependent increase in the incidence of micronucleated polychromatic erythrocyte was observed. All gross and histopathological lesions observed in LCT-treated rabbits were dose-dependent. Liver of the treated rabbits exhibited extensive perihepatitis, hyperplasia of bile duct, necrosis, hemorrhages and congestion. In lungs, there were hemorrhages, thickened alveolar walls, congestion, emphysema, collapsed alveoli and accumulation of extensive inflammatory cells. Kidneys were congested and hemorrhagic whereas renal parenchyma and stroma were normal. Microscopically, heart showed congestion of blood vessels and nuclear pyknosis, myodegeneration. It was concluded from the study that LCT produced toxicopathological alterations in rabbits in a dose-dependent manner. On the basis of the results, it can be suggested that overdosing of LCT be avoided while treating animals for ectoparasites.

Regularities of Variation of the Red Blood Indices Characterizing the Respiratory Function of Blood in Selected FishThere is a large diversity of red blood indices determining oxygen transport ability in vertebrates. In fish this diversity is particularly large, probably due to the great variability in water environments, which impedes the possibility of finding and understanding general patterns. It has been assumed that in mammals, the measure determining the ability of a blood unit to transport oxygen is the ratio of hemoglobin concentration (HB) and total erythrocyte surface area (TSAE). It was also shown that both in mammals and birds the amount of hemoglobin per total surface area unit (Hb/TSAE) conditions maximum use of respiratory pigment in oxygen transport, in different physiological and environmental conditions. In order to check whether this regularity occurs in fish, red blood indices were analyzed in seven species of freshwater fish, differing noticeably in their biology and body mass in two seasons of the year. Notwithstanding this marked seasonal variability to the component variables together determining the total surface area of erythrocytes, the value for TSAE was found to differ in proportion to the higher or lower concentrations of HB. In consequence, the HB/TSAE ratio indicative of the maximal use of haemoglobin in the transport of oxygen was constant in all of the fish studied between analyzed seasons. This constancy - resembling that to be noted in birds - is most probably related to the counter-current gaseous exchange ongoing in the gills of fish.

Objective: This study was aimed to evaluate the antioxidant potential of sinapic acid in both in vitro and in vivo. Recently, we have reported that oral administration of sinapic acid (3,5-dimethoxy 4-hydroxycinnamic acid) an active phyto ingredient widely distributed in rye, mustard, berries, and vegetables has been shown to ameliorate hyperglycemia.Methods: Experimental Type 2 diabetes was induced in male Wistar rats by feeding high-fat diet to induce insulin resistance followed by intraperitoneal administration of a single low dose streptozotocin (35 mg/kg body weight [bw]). Sinapic acid was administered orally at a concentration of 25 mg/kg bw/rat/day for 30 days, and its efficacy was compared with metformin. In vitro, antioxidant scavenging properties of sinapic acid were determined using 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS), superoxide, and nitric oxide (NO) assay.Results: Sinapic acid treatment showed a significant decline in the levels of lipid peroxides, hydroperoxides and protein carbonyls in the plasma and vital tissues of diabetic rats. The treatment also improved the antioxidant status in diabetic rats indicating the antioxidant potential of sinapic acid. In addition, the results of DPPH, ABTS, superoxide, and NO radical scavenging assays substantiate the free radical scavenging efficacy of sinapic acid.Conclusion: The results of this study evidenced that sinapic acid possess significant antioxidant properties which in turn may be responsible for its antidiabetic properties.

The aim of the study was to evaluate the safety and persistence of selected Lactobacillus strains in the gastrointestinal tract (GIT) of healthy adult volunteers after oral consumption of high doses of lactobacilli to identify potential candidates for probiotic and biotechnological applications. In the first phase of the study, nine individuals consumed capsules containing Lactobacillus gasseri 177 and E16B7, Lactobacillus acidophilus 821-3, Lactobacillus paracasei 317 and Lactobacillus fermentum 338-1-1 (each daily dose 1×1010 cfu) for 5 consecutive days. Data on gut health, blood parameters, and liver and kidney function were collected. The persistence of Lactobacillus strains was assessed by culturing combined with arbitrarily primed polymerase chain reaction (AP-PCR) and PCR-denaturing gradient gel electrophoresis (PCR-DGGE) on days 0, 5, 8, 10 and 20 from faecal samples. All strains survived gastrointestinal passage and were detected on the 5th day. L. acidophilus 821-3 was detected in four volunteers on the 8th day (4.3 to 7.0 log10 cfu/g) and in two on the 10th day (8.3 and 3.9 log10 cfu/g, respectively). In the second phase of the study, five additional volunteers consumed L. acidophilus 821-3 (daily 1×1010 cfu) for 5 consecutive days. The strain was subsequently detected in faeces of all individuals using real-time PCR on the 10th day (range 4.6-6.7; median 6.0 log10 cell/g) in both phases of the study for at least 5 days after discontinuation of consumption. The administration of high doses of different Lactobacillus strains did not result in any severe adverse effects in GIT and/or abnormal values of blood indices. Thus, the strain L. acidophilus 821-3 is a promising candidate for probiotic and biotechnological applications. Further studies will be performed to confirm the strain persistence and safety in a larger number of individuals.

This study was carried out to investigate the effect of experimental infection by Escherichia coli on some blood parameters and histopathological changes in male rats to reach this objective twenty male rats (Rattus norvigicus) were divided into two groups, housed under same conditions of water, feed, temperature, light and humidity. The first one served as control group, while the second was experimentally infected with Ecoli by administration of 2ml / rat of (1×109) colony forming unit/ml of E-coli. Five days later blood were obtained from animals by cardiac puncture to measure the total and differential white blood cells count hemoglobin concentration packed cells volume red blood cells count, and thrombocytes count. One animal from each group was killed and histopathological examination was done for intestine kidney liver and spleen to detect the effect of infection on these organs. The results revealed a significant increase in total leukocytes count (P<005) in infected group while the differential count showed a significant increase in neutrophils and significant decrease in lymphocytes (P< 0.05) in same group. There were a significant decrease in hemoglobin concentration packed cell volume and non significant decrease in red blood cells count. While thrombocytes count showed a significant decrease in infected group compared with control group (P<0.05). The histopathological examination of infected male rats intestine was demonstrated mild diffuse inflammation which include increased numbers of neutrophile in tissue intraepithelial lymphocytes and goblet cells In kidney renal tubules showed extensive epithelial swelling with decreased lumen space and generalized necrotic changes with interstitial hemorrhage in renal cortex. In liver hepatocytes were swollen with decreased sinusoidal spaces and widely distributed necrotic foci were seen. There is extensive splenic necrosis with infiltration of leukocytes from white pulp to red pulp of spleen.
