Effect of mineral-vitamin premix on milk productivity and hematological blood parameters of cows

The application of specialized premixes containing all the necessary elements for effective ration enrichment is the main direction of normalizing the mineral and vitamin nutrition of cows. The introduction of biologically active substances into animal diets in the form of premixes helps to increase the efficiency and productivity of the feed application. The purpose of our study was to investigate the effect of the mineral-vitamin premix Biomix on milk productivity and hematological blood parameters of cows. The experiment was carried out on Ukrainian Blackand-White Dairy cows. Two groups were formed for experiment; each group contains 10 heads. The animals of the experimental group were fed by premix Biomix at the rate of 50 g per 1 head per day as a part of the main diet. The control group was fed by the equivalent amount of monocalcium phosphate. The introduction of the Biomix premix into the diet of the research group made it possible to eliminate the deficiency of phosphorus, copper, zinc, cobalt, and iodine, and to bring the level of vitamin D3 to normal. Optimizing of the cows’ mineral and vitamin nutrition through the application of Biomix premix ensured the dairy productivity and the milk quality increase. The average daily milk yield of the experimental cows increased by 5.9 % for 90 experimental days. The fat and protein content increased by 0.05 and 0.07 %, respectively. Cows of the experimental group surpassed the control ones by 153.1 kg in gross milk yield, and by 1.71 kg in average daily yield in terms of 4 percent milk; it is 7.4 % relative to the control (P<0.05). The level of dry matter, calcium, phosphorus, and lactose have increased in milk; its total energy value has also increased. Feed consumption per 1 kg of milk decreased by 5.1 % and 5.4 % in terms of energy and digestible protein. Feeding Biomix premix did not have a negative effect on hematological changes in the body. Morphological and biochemical blood parameters of cows corresponded to physiological norms. An increase in total protein (Р≤0.95), hemoglobin (Р≤0.95), and creatinine (Р≤0.95) was noted. There was a tendency to increase the level of erythrocytes, glucose, urea, and calcium in the blood. Key words: cows, premix Biomix, vitamins, minerals, milk, fat, protein, blood, erythrocytes, hemoglobin.

The Effect of Indigo (Indigofera tinctoria L.) Waste on Growth Performance, Digestibility, Rumen Fermentation, Hematology and Immune Response in Growing Beef Cattle.

This experiment was conducted to assess the effect of indigo waste on the feed intake, digestibility, rumen fermentation, hematology, immune response and growth performance in growing beef cattle. Twenty crossbred beef cattle with an initial body weight (BW) of 145 ± 11 kg were fed four levels of indigo waste for 90 days in a trial. Additions of indigo waste at 0%, 10%, 20% and 30% in a concentrate diet using a completely randomized design (CRD). Cattle were fed concentrate at 1.8% BW, with rice straw fed ad libitum. The concentrate intake decreased linearly (p = 0.01) with the addition of indigo waste. The supplementation with indigo waste reduced dry matter (DM) and organic matter (OM) digestibility cubically (p = 0.03 and p = 0.02, respectively), while increasing neutral detergent fiber (NDF) digestibility cubically (p = 0.02). The final BW of beef cattle decreased linearly (p = 0.03) with the addition of indigo waste. The inclusion of indigo waste decreased the average daily gain (ADG) and gain-to-feed ratio (G:F) linearly (p < 0.01) from 0 to 90 days. The nutrient digestibility, ADG and G:F of beef cattle fed 10% indigo waste in the diet was similar when compared with the control (0% indigo waste). The ruminal pH, ammonia-nitrogen (NH3-N) and total volatile fatty acid (VFA) concentrations were similar among treatments (p > 0.05). The proportion of acetate increased linearly (p < 0.01) but propionate decreased linearly (p < 0.01), resulting in an increase in the acetate to propionate ratio (p < 0.01) when cattle were fed with indigo waste supplementation. Increasing indigo waste levels did not influence blood urea nitrogen (BUN) levels, hematological parameters or immune responses (IgA, IgM and IgG) (p > 0.05). In conclusion, the inclusion of indigo waste at 10% in a concentrate diet did not have a negative effect on feed intake, nutrient digestibility, rumen fermentation, hematology, immune function or growth performance in growing beef cattle.

Metabolic Profile in Dairy Cattle with Displacement of the Abomasum

The objective of this research was to evaluation metabolic, biochemical and hematological parameters in dairy cattle with displacement of the abomasum (DA). In this study, 80 dairy cattle with DA and 10 healthy dairy cattle in early lactation were used. Jugular venous blood samples for blood gases, hematological parameters and serum biochemical analysis of all cattle were taken. Glucose, lactate, triglycerides, BHB, NEFA, insulin, VLDL, GGT, CK concentrations and pH and hematocrit value of cattle with DA were significantly (P

Apoptosis Evaluation in Circulating CD34+-Enriched Hematopoietic Stem and Progenitor Cells in Patients with Abnormally Increased Production of Endogenous Glucocorticoids in Course of Cushing's Syndrome.

Abnormalities in hematological parameters of peripheral blood have been noted in patients with endogenous Cushing's Syndrome (CS) in the corticotropin (ACTH)-dependent and ACTH-independent forms. Nevertheless, the exact mechanism of glucocorticoids (GCs) action on human hematopoiesis is still not entirely clear. The aim of the study was to determine whether endogenous excessive production of GCs could affect apoptosis of CD34+ cells enriched in hematopoietic stem and progenitor cells (HSPCs) collected from the peripheral blood of newly diagnosed CS patients. Flow cytometry, Annexin-V enzyme-linked immunosorbent assay, TUNEL assay, real-time quantitative PCR, and microarray RNA/miRNA techniques were used to characterize CS patients' HSPCs. We found that the glucocorticoid receptor (GR) protein expression levels in CS were higher than in healthy controls. A complex analysis of apoptotic status of CS patients' HSPC cells showed that GCs significantly augmented apoptosis in peripheral blood-derived CD34+ cells and results obtained using different methods to detect early and late apoptosis in analyzed cell population were consistent. CS was also associated with significant upregulation in several members of the BCL-2 superfamily and other genes associated with apoptosis control. Furthermore, global gene expression analysis revealed significantly higher expression of genes associated with programmed cell death control in HSPCs from CS patients. These findings suggest that human endogenous GCs have a direct pro-apoptotic activity in hematopoietic CD34+ cells derived from CS subjects before treatment.

The effect of complex application of symbiotic and biocidal preparations on the metabolic status of broiler chickens' blood

Using probiotic preparations and their complexes in poultry farming is an important step towards increasing poultry resistance and productivity, and thus producing environmentally friendly products. The purpose of the study was to investigate the effect of the complex action of symbiotic drugs and biocidal agents by investigating the clinical and biochemical parameters of blood and mineral metabolism in the body of broiler chickens under the conditions of their use according to the developed scheme. Hematologic, biochemical and immunologic blood parameters were explored by conventional methods, micro- and macroelements by optical emission spectrometry with inductively coupled plasma. Using the proposed complex of symbiotic and biocidal agents in the technology of rearing broiler chickens activates the processes of erythropoiesis, haemoglobin production, restoration of protein metabolism and normalisation of mineral status within physiological limits, which indicates the strengthening of the body's defences, increased resistance to stress factors and adverse environmental conditions, and will further have a positive effect on the growth and productivity of the target bird. The pronounced effect of the complex combination of drugs on the body of broiler chickens of experimental B is a better assimilation of many inorganic elements (by increasing the content of Calcium, Phosphorus, Cuprum, Ferrum and Selenium, Magnesium, Manganum); and, accordingly, causes the sustainable development of metabolic processes due to the prevalence of anabolic over catabolic processes (by increasing the level of total proteins against the background of a physiological increase in the number of globulin fractions; including the induction of the endogenous detoxification system – by reducing the level of production of toxic metabolites of purine metabolism: uric acid and creatinine; reduction of Chromium content; normalisation of transamination processes and deceleration of alkaline phosphatase activity) and immunobiological reactions (by enhancing erythropoiesis and haemoglobin production; induction of lysozyme, bactericidal and phagocytic activity), respectively. The proposed system of rearing young poultry using a complex of symbiotic preparations in combination with biocidal agents promotes the synergistic effect of the latter and their effective action on the body of experimental broiler chickens, which increases nonspecific resistance and restores metabolic reactions

Frequency of JAK2V617F, MPL and CALR driver mutations and associated clinical characteristics in a Norwegian patient cohort with myeloproliferative neoplasms

Myeloproliferative neoplasms are hematological disorders characterized by increased production in one or more myeloid cell lines, associated with driver mutations in JAK2-, MPL- and CALR-genes. The aims of this study were to investigate the prevalence of these driver mutations in a Norwegian patient cohort with myeloproliferative neoplasms, and to assess whether the different mutations were associated with different clinical presentation and natural history. Results from 820 patients in whom analysis for JAK2V617F-, CALR- and MPL had been performed at Haukeland University Hospital in the period 2014-2019 were retrieved and analyzed together with clinical variables related to diagnosis, hematological blood parameters and complications, obtained from patient records. We identified 182 cases of myeloproliferative neoplasms: 78 with JAK2V617F, 28 with CALR-mutations, two with MPL-mutations and 23 cases without a driver mutation. There was a lower prevalence of JAK2V617F mutation than expected in the polycythemia vera group, likely related to overdiagnosis. In patients with essential thrombocytosis, we found significantly higher levels of hemoglobin and erythrocyte volume fraction for JAK2V617F-mutated disease, and significantly higher levels of platelets and lactate dehydrogenase for CALR-mutated disease. Patients with JAK2V617F-mutated primary myelofibrosis had significantly higher levels of hemoglobin, and there was an increased number of smokers or former smokers in this group compared to patients with CALR-mutations. Except for a lower prevalence of JAK2V617F-mutation in polycythemia vera, the mutational distribution in our patient cohort was similar to previous findings in other populations. The novel finding of a higher prevalence of smokers in JAK2V617F-mutated primary myelofibrosis warrants further investigation.

MORPHOLOGICAL INDICATORS OF BLOOD IN CATS WITH CALICIVIROSIS

In recent years, there has been a massive trend in Ukraine to keep cats, which has inevitably led to an increase in the incidence of their diseases. In the general pathology of cats, viral diseases occupy a leading place, and of particular concern is calicivirosis, which is caused by a virus capable of high mutation rates and can cause atypical course with nonspecific manifestations of clinical signs. Therefore, given the urgency of this issue, the result of our research is to clarify, supplement and summarize data on hematological and biochemical parameters of blood and erythrocytopoiesis in calicivirosis in cats, because blood is a sensitive and informative indicator of the body, responds quickly to changes as exogenous. and endogenous factors. The research was conducted in veterinary clinics of Zhytomyr and Kyiv, on purebred and outbred cats (n = 18). Diagnostic studies to confirm feline calicevirus were performed using rapid tests Ag Test (FCV Ag), Quicking Biotech Co., Ltd. and ELISA and PCR for the presence of calicivirus antigen on the basis of a private veterinary laboratory LLC "Bald" in Kiev.&#x0D; Comprehensive studies have shown that cats with calicivirosis (18) are characterized by changes in morphological and biochemical composition of blood. Deviations from physiological limits were found, namely erythrocytopenia P≤0.05, thrombocytosis P≤0.05, leukocytosis P≤0.05, monocytosis P≤0.01, increase in ESR P≤0.001 and lymphocytopenia P≤0.05, for biochemical ones it is a significant increase in the concentration of globulin P≤0.001, creatinine P≤0.001, urea P≤0.05 hyperenzymemia α-amylase P≤0.001, and ALT P≤0.05. As a result of experimental research of morphological indicators of blood the difficult pathogenesis of a disease with multiorgan insufficiency is established.

Feeding barley and corn hydroponic based rations improved digestibility and performance in Beetal goats

The current trial aimed to determine the impacts of fed goats with hydroponic fodder-based maize or barley rations on nutrient digestibility, growth and efficiency of consumed feed, and some blood constituents. Twenty-four post-weaned growing Beetal male kids (3 months of age with an initial body weight of 12.4 ± 0.03 kg) were randomly allocated into six equal groups (n = 4, each one). Each group was offered one of the following dietary treatments: T0, fed 100 % basal diet (BD; containing 80 % Lucerne hay and 20 % wheat straw); T1, fed 80 % BD + 20 % Hydroponic fodder Maize (HFM); T2, fed 80 % BD + 20 % Hydroponic fodder Barley (HFB); T3, fed 60 % BD + 40 % HFM; T4, 60 % BD + 40 % HFB; T5, 60 % BD + 20 % HFM + 20 % HFB for 90 days feeding trial period. Animals were kept under the same hygienic, rearing and environmental conditions. The dry matter and crude protein intake results revealed significant increases in all hydroponic-based rations, with T4 and T5 reporting higher values when compared to the control and other treated groups. Whereas, the T1 group had the maximum fiber intake compared to the other treated and non-treated groups. At the same trend, the T5 group recorded the highest final weight, weight gain, and total weight gain values and the lowest feed conversion ratio compared to the other experimental groups. In addition, goats fed a diet containing two types of hydroponic-based fodder (T5) exhibited a highly significant improvement in all nutrient digestibility and total nitrogen balance compared with other experimental groups. Furthermore, feeding goats hydroponic maize and barley-based rations had no significant influence on blood biochemical and hematological parameters, except that the lymphocyte percentage increased considerably in T2 and T3 groups compared to other experimental groups. In conclusion, in arid and semi-arid regions where most feeds are imported and resources of both land and water are scarce, feeding animal diets incorporating hydroponic fodder might improve growth and production while filling a feed supply gap.

Drinking water chlorination in dairy beef fattening bulls: water quality, potential hazards, apparent total tract digestibility, and growth performance

The first study aimed to evaluate the effect of drinking water disinfection (chlorination: NaClO 15%) and conditioning (acidification: H3PO4 diluted 1:5 in water) on water quality, water and feed consumption, apparent total tract digestibility, and its potential hazardous effects on Holstein bulls fed high-concentrate diets. Twenty-four animals (221 ± 20.9 kg of BW, and 184 ± 9.9 days of age) were individually assigned to one of four treatments according to a 2 × 2 factorial arrangement: conditioning (with or without acidification) and disinfection (with or without chlorination). The entire study lasted 210 days. Physicochemical and microbiological water quality, water and feed consumption, haematological and biochemical blood parameters, and apparent total tract digestibility were measured; data were analysed via a mixed-effects model. Chlorination and acidification increased (P = 0.02) free residual chlorine in water, and chlorination reduced (P = 0.01) total coliform and Clostridium perfringens counts in water. Treatment did not affect water consumption, total DM intake, or blood parameters. At the beginning of the study, NDF digestibility decreased (P = 0.04) with acidification, however, this was restored at the end of the study. The second study evaluated the potential benefit of drinking water chlorination and acidification on the performance of crossbred Holstein bulls fed high-concentrate diets under commercial conditions. Ninety-six animals (322 ± 35.0 kg of BW, and 220 ± 14.2 days of age) were allocated into six pens assigned to one of the two treatments: untreated drinking water or drinking water treated with chlorination and acidification for a total of 112 days. Physicochemical and microbiological water quality, water and concentrate consumption, eating behaviour, growth performance, and carcass quality were analysed via a mixed-effects model. Water conditioning and disinfection increased (P = 0.01) free residual chlorine concentration and reduced (P = 0.04) total coliform count in water. Although water consumption and eating behaviour were similar between treatments, water conditioning and disinfection increased average daily weight gain (P = 0.03), BW before slaughter (P = 0.01), and hot carcass weight (P = 0.01). In conclusion, drinking water chlorination and acidification in fattening dairy beef bulls is recommended as it improves growth performance without any detrimental side effects on health or nutrient digestibility.

Age- and sex-specific reference intervals for complete blood count parameters in capillary blood for Chinese neonates and infants: A prospective study

BackgroundThe reference intervals (RIs) of laboratory tests are essential for disease diagnosis, therapy monitoring, and health assessment. They are also significant for clinicians to discriminate between subjects with disease and healthy subjects. However, RIs for complete blood count (CBC) parameters in capillary blood for children are deficient. This study aimed to establish capillary blood RIs for blood cell parameters in neonates and infants from birth to 2 years of age in Zhengzhou. MethodsWe prospectively collected a total of 1840 capillary blood specimens from healthy subjects from birth to 2 years of age. Hematology RIs were established by analyzing capillary blood sample data, and RIs and 90 % confidence intervals (CIs) were calculated according to Clinical and Laboratory Standards Institute (CLSI) C28-A3 guidelines. ResultsRIs were established for hematological parameters of capillary blood in neonates and infants from birth to 2 years of age. The levels of almost all hematological parameters, except for the lymphocyte (LYMPH), platelet (PLT), and thrombocytocrit (PCT) parameters, peaked in the first month after birth and then decreased to lower levels within 6 months. There were significant sex differences in most erythrocyte-related parameters, with higher levels in males than in females. Erythrocyte-related parameters showed an increasing tendency with increasing age after the second month. Neutrophil (NEUT) levels were high on the third day of life, declined to a nadir in the first month, and then slowly increased with age. LYMPH levels were low at birth and began to increase after birth, peaked at approximately-six months of age and then gradually declined with age. PLT and PCT levels showed an increasing trend during the first month, while the other parameters showed a decreasing trend. All platelet-related and leukocyte-related parameters showed no significant difference with sex. ConclusionWe provide comprehensive age- and sex-specific RIs, including RIs for neonates in Henan. Our study provides more comprehensive reference ranges for Child Health Hospital and children's medical institutions, which may facilitate preliminary screening, diagnosis, and therapy.

Antidiabetic and Toxicity Studies of the Extract of Four Nigerian Medicinal Plants

Aims: To evaluate the anti-hyperglycaemic efficacy and safety of the methanol extract of the combination of Senecio biafrae leaf, Xylopia aethiopica fruit, Carica papaya seed and Spondias mombin stem bark mixed together in ratio 1:1:1:1&#x0D; Study Design: Extract of medicinal plants was assayed using glucose and streptozotocin-induced herperglycaemic rats model.&#x0D; Place and Duration of Study: Department of Pharmacognosy, Obafemi Awolowo University, IleIfe, Nigeria, between May, 2019 and January, 2022.&#x0D; Methodology: The extract of the combined plant parts was tested for toxicity in rats while its effects on glucose level, blood and biochemical components were also assessed. Its in-vitro anti-hyperglycaemic activity was assayed in α-amylase and α-glucosidase inhibitory models while its in-vivo effects were tested in glucose and streptozotocin-induced hyperglycaemic rats. The antioxidant activity of the extract was also carried out.&#x0D; Results: The extract did not show any adverse effects on blood sugar levels, haematological and biochemical parameters in normal rats in sub acute toxicity tests. The extract gave comparable (p &gt; 0.05) α-amylase and α-glucosidase inhibitory effects to acarbose. In glucose-induced hyperglycaemic rats, its 100 mg/kg was the most effective dose with 19, 40, 43, and 57% activity that was significantly higher (p &lt; 0.05) than the 10, 18, 24, and 40% activity given by glibenclamide (5 mg/kg) at the same time points. In streptozotocin-induced diabetic assay, its 50 mg/kg showed 31, 85, 85 and 82 % effects on days 4, 7, 10 and 14, respectively that was significantly higher than its 100 mg/kg and glibenclamide on days 7 and 10. The extract also elicited high free radical scavenging effects in all the antioxidant assays.&#x0D; Conclusion: The extract of the combination of four Nigerian antidiabetic plants mixed together in equal ratio gave significantly better antidiabetic activity at low doses than the individual plants without toxic effects.

The effectiveness of the association of probiotics in the diets of sheep

Relevance. Of scientific interest are studies on the physiological effect of the association of probiotic strains of microorganisms for their subsequent use by ruminants in order to increase productivity due to increasing the adaptive capabilities of the body.Methods. To study the effect of feeding the association of probiotics in loose and granular species, physiological experiments were conducted on animals with chronic rumen fistulas, with the study of the characteristics of consumption and digestibility of feed nutrients, nitrogen balance, indicators of scar digestion, microbiota of the large intestine, features of metabolic processes in the body and indicators of natural resistance according to generally accepted modern research methods.Results. The positive effect of feeding the association of probiotics at dosage7 g/head/day in bulk and in mini-granules on feed consumption, digestibilitywas revealed, with an increase in the amount of compound nutrients and an increase in digestibility coefficients, as well as nitrogen retention. Higher levels of mass formation of bacteria, protozoa, their amounts both before and after feeding, with a higher concentration of volatile fatty acids, amylolytic activity were found in the scar content. In microbiological studies of fecesunder the influence of the probiotic association, higher levels of lactobacilli, bifidobacteria were found, with a lower level of lactose-positive non-pathogenic microorganisms belonging to the Escherichia coli group of pathogenic molds, enterococci. The improvement of carbohydrate-fat and protein metabolism, as well as hematological parameters of blood in the body of animals receiving probiotic strains was found. The data obtained indicate the expediency of using probiotic associations in ruminants to improve metabolic processes in the body as a basis for increasing productivity and to improve adaptive capabilities.

Assessment of flax and hemp fibres in terms of their impact on the growth performance and health status of weaned piglets

Weaning is a critical phase in intensive piglet production marked by the frequent occurrence of digestive disorders posing health and economic burden. To stave off such weaning-related problems, antibiotics and supplements containing high levels of ZnO are often used. In this study, we investigated whether natural fibres obtained from two plants known for their dietary fibre profile and antioxidant properties: flax (Linum usitatissimum L.) and hemp (Cannabis sativa L.), can serve as a health-promoting diet supplement. The study was conducted on a total of 191 Polish Large White piglets from 18 L, from their birth to 56 days of age. Piglets were divided by litters into six groups: W1.5, F1.5, H1.5, W2.0, F2.0, and H2.0. Groups W1.5, F1.5, and H1.5 received feed supplemented with 1.5% fibre from wood cellulose (W), flax (F), and hemp (H), respectively, while groups W2.0, F2.0, and H2.0 received feed with a higher 2.0% content of the same fibres. Flax and hemp fibres were characterised by a complex composition, antioxidant properties due to the presence of phenolic acids, and low risk of mycotoxin contamination. Flax fibre resulted in best weight gains and feed conversion ratio (P ≤ 0.05) of piglets, while hemp fibre had higher positive effect on antioxidant status (P ≤ 0.05) compared to the other two fibre additives. Neither flax nor hemp fibres had any adverse effect on the haematological and biochemical blood parameters. Piglets receiving a diet with 1.5% added fibre showed better growth performance, while diet supplementation with 2% fibre had a beneficial effect on the content of butyric acid in the small intestinal chyme (P ≤ 0.05). The results suggested that both flax and hemp fibres can be innovative feed additives for weaned piglets. However, further studies should be conducted in commercial farms, as the effects of dietary fibre could vary in more challenging environmental conditions.

Productivity and hematological parameters of blood of young pigs at fatten-ing for feeding protein vitamin mineral supplement

The article presents data on the productivity and hematological parameters of the blood of young pigs for fattening for the inclusion in their diet of a new protein vitamin-mineral supplement with essential oils, Efiprot. Plant essential oils are natural phytobiotics containing fat-soluble vitamins, polyunsaturated fatty acids, volatile acids, aldehydes, and other biologically active substances with bactericidal and antiseptic properties, increased appetite, and secretion of digestive juices. Thus, they provide better feed conversion and increased productivity. Protein vitamin-mineral supplement Efiprot is for a diet consisting of barley grains (50 %) and wheat grains (35 %). The experiment was carried out on two groups (12 heads in a group) of young pigs, a cross of Large White and Landrace. At the beginning of the experiment live weight of the animals was 35 kg; at the end, it was 110 kg. Control group animals were fed a supplement without essential oils; experimental group animals were additionally fed a dose of essential oils (200 g per 1 ton of supplement). Feeding supplements with essential oils positively affected pig productivity and feed growth. The absolute increase in live animals of the experimental group averaged 68.6 kg, average daily was 762 g; the corresponding values of the control group were 63.8 kg and 709 g for 90 days. Feeding protein vitamin-mineral supplement (PVMS) increased average daily gain by 53 g or 7.48 %, while feed consumption per 1 kg of live weight gain was lower by 0.3 energy feed units or 6.69 % than the control one. Hematological parameters of pig blood fed by PVMS Efiprot corresponded to the limits of the physiological norm. At the end of the experiment, an increase in erythrocytes, total protein, and hemoglobin was observed in the blood of the experimental animals, which is consistent with an increase in meat productivity. A slight increase in the mass of basophils, eosinophils, and leukocytes is adaptive and incredible.

Phytochemical Test and Acute Safety Evaluation of Oral Purple Leaves (Graptophyllum Pictum L. Griff) Extract in Rats

Background: Purple leaves (Graptophyllum pictum (L) Griff) is a native plant from Indonesia (Polynesia) which is empirically common used to treat hemorrhoids, diabetes, and many other diseases. Despite its massive development globally, there are few studies have written about the toxicity of this herbal medicine. Aim: The aim of this study is to describe the acute toxicity of this herbal medicine, as the basic ground of the further safe development of this medicine. Method: Each purple leaf dry powder (2 kg) was extracted with 15 L of 70% ethanol and 15 L of hexane by maceration method for 3 days at room temperature and then filtered to obtain macerate liquid. The study was conducted on 36 male 6-8 weeks, Sprague–Dawley (SD) rats. The result was presented as the mean value ± standard deviation (SD). Data were evaluated for homogeneity using Saphiro Wilk. The comparisons between pre dan post treatment body weight were measured by paired student t test and hematological measurements were analyzed by ANOVA. P value less than 0.05 was considered significant. Results: Acute toxicity of ethanol and hexane extract were assessed following a single dose administered by gavage at a dose of 50, 2000 and 3000 g/kg bw. The mean body weight of rats increased from 150 ± 2.22 g to 161 ± 6.68 g during the 14 days. The difference of body weight between before and at 14 days amongs groups were significantly different with P value <0.01. Conclusion: The present study showed that hexane extract contains more valuable components for medical treatment purposes. The acute toxicity on 50, 2000,3000 kg/BW oral ethanol and hexane extract of Graptophyllum pictum showed no significant influence on hematological blood parameters of rats. It is safe to administered orally ethanol or hexane extract of G. pictum below 3000mg/kgBW rats.

DYNAMICS OF BLOOD HEMATOLOGICAL PARAMETERS DURING TREATMENT EIMERIOSIS (EIMERIA TENELLA) OF CHICKENS WITH ARTEMISIA ABSINTHIUM

The chickens of local rocks breed were grown in the vivarium of the Institute of Zoology up to 20 days of age. Chickens were fed with standard bird combined feed for broilers. For studying the dynamics of hematological parameters of blood of local pockmarked rocks chickens infected with E.tenella and treated of Artemisia absinthium were divided into three groups of 20 birds each. Chickens of the first group were not infected (control). Chickens second and third groups were infected E.tenella with dose of 20,000 sporulated oocysts. The second group of chickens was not treated (control 2), and the third group of chicks was allowed A. absinthium 1500 mg per kg feed at the following day after the infection for 10 days. In the blood of chicks infected with Eimeria tenella number of erythrocytes, eosinophils, pseudo-eosinophils&nbsp;decreases and the number of monocytes increases (P &lt;0,05). Decrease in the number red blood cells reduces the amount of hemoglobin.

Influence of 24 h Simulated Altitude on Red Blood Cell Deformability and Hematological Parameters in Patients with Fontan Circulation.

Patients with Fontan circulation are particularly dependent on low pulmonary vascular resistance because their lungs are passively perfused. Hypoxia drives pulmonary vasoconstriction; thus, red blood cell (RBC) deformability and stability of hematological parameters might be of particular importance, because alterations during hypoxia might further influence circulation. This study aimed to measure respective parameters in patients with Fontan circulation exposed to normobaric hypoxia. A total of 18 patients with Fontan circulation (16 to 38 years) were exposed to normobaric hypoxia (15.2% ambient oxygen). Blood samples were taken in normoxia, after 24 h in hypoxia, and 60 min after return to normoxia. Blood count, RBC age distribution, EPO, RBC deformability, marker of RBC nitric oxide, oxidative state, and RBC ATP were measured. Hypoxia increased oxidative stress in RBC, but without affecting RBC deformability. RBC age distribution remained unaffected, although EPO concentrations increased, followed by a rise in reticulocyte count at an already high hematocrit. NO metabolism was not affected by hypoxia. Modest normobaric hypoxia for 24 h did not impair RBC deformability in patients with Fontan circulation; however, the oxidative system seemed to be stressed. Given the high baseline Hct in these patients, hypoxia-induced erythropoiesis could adversely affect rheology with more prolonged hypoxia exposure.

Evaluation of metabolic stress status in common carp (Cyprinus carpio) exposed to the fungicide folpet

Among pesticides, fungicides are the most extensively used ones in agriculture and their effects on fish health and indirectly human health are needed to evaluate. Folpet has been used for over 50 years as a fungicide across the world. The mechanism of action of folpet on non-target aquatic organisms is so poorly understood and there is no available information about potential acute toxicity of folpet and its mechanism of action in non-target aquatic organisms. With this motivation, two successive experiments were set up: first, 96 h-LC50 value of folpet for common carp (Cyprinus carpio) was determined; and second, effects of different sublethal concentrations (0, 0.025, 0.50, 0.1 and 0.15 mg/L) of folpet on hematological serum biochemical blood parameters, DNA damages, expression levels of catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione S-transferase (GST), and cortisol receptor (HSP70) genes were evaluated in this study. It was calculated that 0.199 mg/L of folpet was the 96 h-LC50 value. After the folpet exposure for 14 days, significant decreases in red blood cells, hemoglobin, hematocrit, serum total protein, and GST gene expression levels were observed while serum glucose, liver enzymes activities, and expression levels of CAT, SOD, GPx, HSP70 genes increased. Also, folpet induced a significant genotoxic effect on the blood cells regarding to DNA damages. Consequently, the results have shown the toxic effects of folpet even at the lowest concentration on common carp.

Clinical and biochemical status of patients with ulcerative collitis

Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), are chronic inflammatory conditions of the gastrointestinal tract characterized by a relapsing and remitting course. Aim - to analyze clinical data and the most significant hematological and biochemical blood parameters used for diagnosis in patients with ulcerative colitis. Materials and methods. Between 2020 and 2021 examined 50 patients with the diagnosis "Ulcerative colitis" living in the Samara region. The diagnosis of ulcerative colitis was confirmed by a combination of clinical, radiological, endoscopic, and histopathological criteria generally accepted for inflammatory bowel diseases. A hematological blood test was performed on an automatic hematological analyzer Sysmex KX-21N, Japan, and a biochemical blood test was performed on an automatic biochemical analyzer Hitachi 902, Japan. Results. In the biochemical analysis of blood, an increase in the content of C-reactive protein in the blood is expected in 64% of patients. In 40% of patients, the concentration of total protein and electrolytes decreases. An increase in glucose levels was revealed in 44% of patients, in 10% of cases, a decrease in creatinine concentration, an increase in the activity of ALAT and ASAT was noted in 6 and 4% of cases, respectively. Reduced urea levels are noted in 6% of patients. Conclusion. As a result of the study, the data necessary for the diagnosis and monitoring of the effectiveness of the treatment of ulcerative colitis were obtained.
