<p><strong>Background:</strong>Dimethylnitrosamine (DMN) is a potent hepatotoxin, carcinogen and mutagen which exerts carcinogenic effects and induces hepatic necrosis in experimental animals through metabolic activation by CYP2E1. This study thus evaluated efficacies of <em>Annona muricata</em> pre-treatment on acute dimethylnitrosamine (DMN)-induced anemia and biochemical alterations in male albino rats.</p><p><strong>Methods:</strong>Four (4) groups of six (6) rats each were used for the study. Group 1 served as control and was untreated, group 2 and 3 were pre-treated with 400mg/kg <em>Annona muricata</em> ethanol leaf extract for one week while group 3 and 4 each received single dose of 20mg/kg DMN (orally) after one week. The rats were sacrificed 48hrs after DMN administration.</p><p><strong>Results:</strong>In rats administered 20mg/kg DMN, toxicty was clearly shown by decreased activities of serum liver synthetic molecules namely total protein, albumin, increased total bilirubin, increased kidney parameters such as creatinine and urea as well as decreased body weight gain. The toxic effect of DMN was also indicated by significantly decreased levels of red blood cells (RBC), hemoglobin (Hb), packed cell volume (PCV), white blood cells (WBC) and platelet count (Plt count). However, in rats pre-treated with 400mg/kg <em>Annona muricata</em> prior to DMN administration, there were significant reversals in the activities of serum liver synthetic molecules, kidney profiles, and hematological parameters when compared to DMN-alone administered rats.</p><p><strong>Conclusion:</strong><em>Annona muricata</em> pre-treatment exhibited <em>in vivo</em> protective and anti-anemic effects against DMN-induced injury.</p>

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.

The present study investigates the antidiabetic potential of polyphenol extracts purified from guava pulp, seeds and leaves using an in vivo experiment on albino rats. The polyphenols from guava pulp, seeds and leaves were extracted using methanol solvent and the sonication method while being evaluated by total phenolic contents and radical scavenging activity assay. The proximate composition of powders revealed that ash, protein and total sugars were significantly (p < 0.05) higher in leaves and seeds, while vitamin C was highest in pulp. Total phenolic and antioxidant activities were highest in pulp followed by leaves and seeds. The findings of feed intake and body gain revealed that the supplementation of polyphenols, especially from pulp, significantly (p < 0.05) increased the feed intake, which resulted in increased body weight. Moreover, total cholesterol (TC) and low-density lipoprotein (LDL) levels were significantly (p < 0.05) decreased, while the level of high-density lipoprotein (HDL) was increased in groups fed with polyphenols from guava pulp compared to both (+ive and –ive) control groups. Furthermore, blood glucose and triglycerides were significantly (p < 0.05) decreased in supplemented groups compared to the control group of diabetes mice, which resulted in the inhibition of α-amylase and glucose transport. Besides this, packed cell volume (PCV), mean corpuscular volume (MCV), hemoglobin, red blood cells (RBCs), white blood cells (WBCs) and platelet levels were increased significantly (p < 0.05) in pulp’s extract followed by leaves and seeds compared to both control groups. Overall, the antidiabetic potential of different extracts was in the following order: pulp > leaves > seeds. The findings suggest the feasibility of adding 200–250 mg/kg.bw of polyphenol extracts of pulp as an alternative to diabetic drugs.

In this study we evaluated the possible protective effects of selenium (Se) on hematological and oxidative stress parameters in rats chronically treated with cisplatin (cisPt). Four groups of Wistar albino rats were examined: a control, untreated rats (I), rats treated with Se (II), rats treated with cisPt (III), and rats treated with Se and cisPt (IV). All animals were treated for 5 days successively and killed 24 h after the last treatment. Hematological and oxidative stress parameters were followed in whole blood and red blood cells (RBC). Results showed that the chronic application of Se was followed by a higher number of reticulocytes and platelets, increased lipid peroxidation and GSH content in the RBC. Cisplatin treatment induced depletion of RBC and platelet numbers and an elevation of the superoxide anion, nitrites and glutathione levels. Se and cisPt co-treatment was followed by an elevation of the hematological parameters and the recovery of the glutathione status when compared to the control and cisPt-treated rats.

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.

The Impact

Several immune and hematological parameters are associated with survival in patients with oropharyngeal cancer (OPC). The aim of the study was to analyze selected immune and hematological parameters of patients with HPV-related (HPV+) and HPV-unrelated (HPV-) OPC, before and after radiotherapy/chemoradiotherapy (RT/CRT) and to assess the impact of these parameters on survival. One hundred twenty seven patients with HPV+ and HPV− OPC, treated with RT alone or concurrent chemoradiotherapy (CRT), were included. Patients were divided according to HPV status. Confirmation of HPV etiology was obtained from FFPE (Formalin-Fixed, Paraffin-Embedded) tissue samples and/or extracellular circulating HPV DNA was determined. The pre-treatment and post-treatment laboratory blood parameters were compared in both groups. The neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), monocyte/lymphocyte ratio (MLR), and systemic immune inflammation (SII) index were calculated. The impact of these parameters on overall (OS) and disease-free (DFS) survival was analyzed. In HPV+ patients, a high pre-treatment white blood cells (WBC) count (>8.33 /mm3), NLR (>2.13), SII (>448.60) significantly correlated with reduced OS, whereas high NLR (>2.29), SII (>462.58) significantly correlated with reduced DFS. A higher pre-treatment NLR and SII were significant poor prognostic factors for both OS and DFS in the HPV+ group. These associations were not apparent in HPV− patients. There are different pre-treatment and post-treatment immune and hematological prognostic factors for OS and DFS in HPV+ and HPV− patients. The immune ratios could be considered valuable biomarkers for risk stratification and differentiation for HPV− and HPV+ OPC patients.

Abstract Ethnopharmacological relevanceAnemia is a very serious condition in Zambia. One of the plants that has been used traditionally is Phyllanthus muellerianus where different parts of shrub are used to treat a number of diseases in Zambian folklore medicine. Earlier studies have investigated medicinal properties of its aqueous root extracts. This study evaluated the effect of P. muellerianus roots on the hematological indices of albino rats and determined its phytochemical profile. Aim of the studyTo carry out phytochemical screening of the root extract and assess the ant-anemic effect of the aqueous extract on laboratory rats with tail-bled induced anemia Materials and MethodsThirty-six male albino rats placed in six groups were used for the study. The groups comprised the 100, 200, and 400 mg/kg plant extract, Ranferon (200 mg/kg) positive control, anemic non treated control and a normal (non-anemic) control. Anemia, induced through bleeding of the rats, was defined as hemoglobin (Hb) levels less than 12 g/dL. The anti-anemic potential of the plant was determined by comparing its effect on the hematological parameters of rats on treatment to that of the control group.ResultsAfter treatment, rats on the 400 mg/kg plant extract dose showed the greatest increase in the mean values for Hb, Packed cell volume (PCV) and RBC count were 43.3±1.2%, 15.4±0.3 g/dL and 6.3±0.3 x106 /mL respectively, when compared to the negative control group (P < 0.05). Phytochemical screening revealed positive results for alkaloids, flavonoids, saponins, glycosides, steroids, triterpenoids and tannins with varying amounts.Conclusions. The aqueous root extract of P. muellerianus was efficacious against anemia in a dose-dependent manner. The phytochemical compositions seem to be responsible for its hematopoietic properties. Thus, the root decoction of P. muellerianus is useful in alleviating anemia and the results lend credence to its use in traditional medicine in the management of anemia.

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.

Antioxidative Status

Aspartame (ASP) is one of the most widely used nonnutritive sweeteners. This study investigates the chronic effects of ASP on hematological and biochemical parameters, and its effects on the oxidative/antioxidative status in the red blood cells of Wistar albino rats. Rats were provided with ASP (40 mg/kg/daily for six weeks) in drinking water. Increased food and fluid intake was observed in the ASP-treated rats. Total body mass was significantly decreased in the ASP-treated rats. Treatment with ASP caused an increase in the concentrations of glucose, cholesterol, LDL-cholesterol, and in the activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH), as well as a decrease in the levels of HDL-cholesterol in the serum. A significant decline in the number of white blood cells (WBC) was observed after ASP uptake. Based on the results we conclude that ASP induces oxidative stress, observed as an alteration of the glutathione redox status, which leads to increased concentrations of nitric oxide (NO) and lipid peroxides (LPO) in the red blood cells. Changes in biochemical parameters, lipid metabolism, as well as changes in the levels of oxidative stress markers and the appearance of signs of liver damage indicate that chronic use of ASP can lead to the development of hyperglycemia, hypercholesterolemia and associated diseases.

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.
