The overall objective of this study was to evaluate the hemolysing action of Naja nigricollis venom on rabbit blood. To carry out this study, three batches of three rabbits were formed with two control batches and one experimental batch. Each control lot is composed of three rabbits (males or females) while the experimental lot is composed of two males and one female. Each rabbit from the control lots was separately collected in the purple tube (EDTA) and transported to the laboratory for analysis. The rabbits from the experimental batch were also collected distinctly a few minutes after the injection of the venom of Naja nigricollis for the analysis of haematological parameters. However, before the analysis of the hematological parameters of the rabbits from the control and experimental batches, an in vitro hemolysis test of Naja nigricollis venom was performed to verify its hemolysing power. The results showed that Naja nigricollis venom has a dose-dependent in vitro hemolysing power. As for the haemogram, it revealed that the venom of Naja nigricollis has a decreasing effect on blood cells (red and white blood cells), on haemoglobin and on haematocrit, and an elevation on MGVs thus promoting anaemia.

Objective: The aim of the present study was to investigate the protective efficacy of rotenone against lipopolysaccharide (LPS) and D-galactosamine (D-GalN)-induced altered hematology. Methods: Hematotoxicity was induced by coinjection of LPS (50 μg/kg i.p.) and D-GalN (300 mg/kg i.p.). Rotenone (5, 10 and 20 mg/kg p.o.) was administered for 6 days as a pre-treatment. Blood was collected through puncturing the retro-orbital sinus to analyze blood parameter. Serum was separated to analyze glucose, triglyceride, and cholesterol. Results: The present study revealed decreased in red blood cells, platelets, hemoglobin, and hematocrit value while a significant increase in white blood cells, lymphocyte, and monocytes were observed in LPS and D-GalN treated rats. LPS and D-GalN administration significantly decrease glucose level while serum lipid profile (triglycerides and cholesterol level) were increased significantly at 5% level of significance. LPS and D-GalN-induced altered hematological and serological variables were restored toward control by rotenone pretreatment for 6 days in dose-dependent manner. Conclusion: It can be said that LPS and D-GalN administration resulted in alteration of various hematological parameters and rotenone at 20 mg/kg dose restored significant alteration toward control due to the presence of antioxidant activity of rotenone.

An 8-year-old boy with chronic granulomatous disease (CGD) was admitted in moribund condition with aspergillus pneumonia. Because of the gravity of the situation, normal granulocyte infusions were used as adjuncts to the more conventional antimicrobial therapy. White blood cells, derived from a total of 58 units of whole blood obtained by leukophoresis of the father, were given in two separate doses. The first dose, totaling 2.8 x 1010 granulocytes, was coincident with significant improvement, and the second, totaling 3.0 x 1010 granulocytes, was coincident with the onset of clinical improvement and interim recovery. Transient improvement in in vitro granulocyte function was noted in cells taken from the patient's blood immediately after infusion. No adverse effects of the infusions were noted in either the patient or the donor. Although it is impossible to divorce the therapeutic effect of the granulocyte infusions from the more conventional therapy, we conclude that normal granulocyte infusions can be considered a valid adjunct in children with CGD who are suffering from a life-threatening infection.

Purpose: to study hematological parameters of blood in bulls-producers of dairy breeds on the day of semen collection in the Udmurt Republic after a long winter period of operation, depending on the breeds, age and place of selection.Materials and methods. The work was performed at the Federal Research Center for Animal Husbandry named after Academy Member L. K. Ernst on the basis of AO "Udmurtplem" of the Udmurt Republic in the period from 2020 to 2021 on dairy bulls (n=20) aged 15-69 months, including a purebred Holstein breed of domestic selection (n=6), a Holstein black-and-white breed of European selection (the Netherlands, n=6), a black-and-white breed with blood transfusion on Holsteins on at the level of 94-98% (n=8). The content of white blood cells, red blood cells, hemoglobin and hematocrit, depending on age and breed, was studied on the ABC VET hematological analyzer on the day of taking the seed.Results. It was found that on average, in 20 bulls aged 15-69 months, the level of white blood cells was at the level of reference values of 8.8±0.25 x 109/l, red blood cells 10.3 x 1012/l, which is 50% more than the reference values. The concentration of hemoglobin is 128.0±2.92 g/l, hematocrit is on average 54.3%, with a norm of 24-46%. Breeding bulls at a reliable level, differing in age, showed that some animals had high indicators for red blood cells of 10.3±0.26 x 102, for hematocrit of 54.3% against 24-46% of reference values. Also, according to hematological indicators, there was a tendency to increase the concentration of hemoglobin and hematocrit in European-bred bulls.Conclusion. The study of the variability in hematological parameters depending on the selection showed that there is no significant difference in leukocytes and all indicators are at the level of reference values, and in erythrocytes more than 50% than the highest indicators. The highest hemoglobin values were at the level of 141-156 g/l instead of 128 g/l according to the highest reference values. Hematocrit also showed high max values in all groups in comparison with the reference values of 59-66% versus 46% in the norm. It is necessary when analyzing hematological blood parameters in addition to the average statistical indicators (M+m) also, monitor the variability (min-max) in order to obtain more objective information.

In Vitro Data

To evaluate the effects of blood cells on the response of platelets to aggregating agents using whole blood impedance aggregometer, studies were carried out on whole blood (WB) of normal subjects and of patients with: polycythemia vera (PV), iatrogenic anemia (IA), primary thrombocytosis (PT), idiopathic thrombotic purpura (ITP), myeloid chronic leukemia (MCL), iatrogenic leukopenia (IL). The in vitro effects of red blood cells (RBC) and of white blood cells (WBC) on platelet rich plasma (PRP) aggregation were also evaluated. WB, PRP, WBC and RBC were prepared by conventional methods. Aggregation was performed using the impedance aggregometer (mod. 540, Chrono Log Corp). In normal subjects the concentration of collagen giving 50 % aggregation (AC50 ) found in PRP did not differ from that of WB, indicating that hematocrit values within the normal range did not appreciably affect platelet aggregation. The results obtained in WB of patients are summarized in the table: In vitro data showed that aggregation in prp in wb of normal subjects was related to the number of platelets present in the sample. RBC added to PRP significant reduced aggregation only when the RBC number was greater than 4.101 cells. No effect of WBC on collagen induced aggregation of PRP was observed, whereas significant inhibition was detected after ADP. It is concluded that the aggregation evaluated in WB with impedance method is dependent on the platelet number. Also, in vitro data and studies in WB of patients indicate that aggregation is significantly affected by the presence of cells other than platelets only in conditions of changes of the ratio between platelets and leukocytes and/or red cells.

Nitrofurantoin (NT) used for the treatment of urinary tract infections may have antiplasmodial activity. Dihydroartemisinin-piperaquine (DP) is an artemisinin based combination therapy used for the treatment of malaria. This study evaluated the antiplasmodial effect of dihydroartemisinin-piperaquine-nitrofurantoin (DP-NT) on mice infected with Plasmodium berghei. Adult Swiss albino mice (30-35 g) of both sexes were used. The mice were randomly grouped, inoculated with Plasmodium berghei, and treated orally with DP (1.7/13.7 mg/kg), NT (57.1 mg/kg) and DP-NT (1.71/13.7/ 57.1 mg/kg), respectively using curative, prophylactic and suppressive tests. The negative control was orally treated with normal saline (0.3 mL), while the positive control was orally treated with chloroquine CQ (10mg/kg). After treatment, blood samples were collected and evaluated for percentage parasitemia, inhibitions and hematological parameters. Liver samples were evaluated for histological changes. The mice were observed for mean survival time (MST). Treatment with DP-NT decreased parasitemia levels when compared to individual doses of DP and NT with significant difference observed at p<0.05. DP-NT prolonged MST when compared to individual doses of DP and NT with significant difference observed at p<0.05. The decrease in packed cell volume, red blood cells, hemoglobin and increase in white blood cells in parasitized mice were significantly restored by DP-NT  when compared to individual doses of DP and NT with difference observed at p<0.05. DP-NT eradicated liver Plasmodium parasite.  NT remarkably increased the antiplasmodial activity of DP. DP-NT may be used for the treatment of malaria.

Purpose This paper aims to evaluate the therapeutic potential of apple extracts against thrombocytopenia, i.e. decrease in platelet count. Design/methodology/approach Male Sprague Dawley rats were used to evaluate therapeutic potential of apple extracts. Diets enriched with apple fruit and seed’s ethanolic extract were provided to normal and KBrO3-induced thrombocytopenic rats for 60 days. KBrO3 was administered at level of 85 mg/Kg of body weight of rats to intentionally decrease the platelet count. Platelet count and other hematological parameters were monitored at monthly intervals to evaluate therapeutic effect of apple extracts against thrombocytopenia. Findings The results of current research portrayed that both apple seed and fruit extracts enriched diets increased the platelet count significantly (p < 0.05) in thrombocytopenic rats. It was observed that apple fruit extract-enriched diet (AFE) raised the platelet count to 14.72 and 33.07 per cent in normal and thrombocytopenic rats, respectively. Apple seed extract-enriched diet (ASE) raised the platelet count to 11.08 and 32.90 per cent in normal and thrombocytopenic rats, respectively. Other hematological parameters including white blood cells, red blood cells and hemoglobin were also significantly increased. Originality/value Thrombocytopenia is uprising problem in developing world including India and Pakistan accompanied by different diseases especially dengue and related complications. Because of questioning on therapies against thrombocytopenia, research on diet-based therapies, as a substitute to synthetic one, is increasing. Diet rich in antioxidant compounds including apple fruit and seeds are the limelight of manuscript.

The hematological parameters red blood cells (RBC) and total white blood cells (WBC) counts, hematocrit, hemoglobin concentration, and RBC indexes (median corpuscular volume and median corpuscular hemoglobin concentration) were determined and T CD5+ lymphocytes and CD4+ and CD8+ subpopulations of the umbilical cord blood (UCB) of dogs were quantified by the cytofluorimetric technique. Nine adult Beagles, from two do five-year old, were used as control. The umbilical cord blood (UCB) was collected from 20 neonate dogs. The method for the UCB collection was adequate to obtain sufficient quantity of blood for the accomplishment of the hematological analyses and lymphocyte quantification. Cytoscopic preparations of the UCB suggested high erythropoietic activity. There was no difference for the global leukocyte and lymphocyte counts between the groups. UCB T lymphocyte counts were lower than those obtained for adult dogs. The proportion of CD4:CD8 showed a great dominance of T CD4+ cells over T CD8+ lymphocytes in UCB.
