Introduction. Epoxiconazole is a highly effective triazole fungicide. It is a part of many modern compounds for the control of phytopathogens. Widely used in agriculture in all over the world and in Ukraine, in particular. Despite its hepatotoxic characteristics, this fungicide alters the hematological parameters of blood.The aim of the study – to investigate the effects of generic triazole fungicide epoxiconazole, 95% on hematological and cytochemical parameters of peripheral blood of Wistar Hannover rats in acute experiment.Research Methods. 10 healthy males of Wistar Han rats were equally divided into control (0 mg/kg/bw) and experimental groups. Dose 1580 mg/kg/bw of epoxiconazole (1/2 LD50) was administrated once orally by gavage to 5 experimental rats. Peripheral blood was studied at 0 and 1, 3, 7, 14 day after exposure (DAE). RBC, HGB, HCT, erytrocyte indices MCV, MCH, MCHC, WBC and PLT were, hemogram and morphological disturbances of cells were studied,percentage ratio of different types of leukocytes was calculated.The cytochemical status of leukocytes was assessed on the basis of determining the enzymatic activity of specific naphthol-AS-D-chloroacetateterase in neutrophils, succinate dehydrogenase and acid phosphatase in lymphocytes.Results and Discussion. Erythrocytosis in response to pesticide intoxication with a decrease of mean cellhemoglobin concentration in one erythrocyte; the reduction of hemoglobin concentration in the end of experiment against the background of active polychromasia confirmed the anemic effect of epoxiconazole. Reactive neutrophilia, stimulation of lymphocytopoiesis and monocytopoiesis, appearance of macrophages in the peripheral blood, increased activity of naphthol-AS-D-chloroacetateterase, succinate dehydrogenase and acid phosphatase were considered as compensatory mechanisms. Reverse quantitative changes in the ratio of lymphocytes subpopulations based on the activity of acid phosphatase were noted.Conclusions. Results of the study of generic fungicide epoxiconazole, 95% hematotoxic activity in the acute experiment on Wistar Hannover male rats showed the development of latent anemia, which was manifested in the late-term study; activation of monocytopoesis; increase of macrophages in the peripheral blood; changes in the immune response of the body and the appearance of atypical normocytes and lymphocytes with nuclear abnormalities.

Ficus vogelii is a medicinal plant mainly found in tropical Africa and reported to treat inflammatory complaints. This study aims to evaluate the acute and sub-chronic toxicity of the aqueous extract of Ficus vogelii stem bark in wistar rats. For acute study, aqueous extract at a single dose of 5000 mg/kg body weight was administered to female rats and observed for 14 days. In the sub-chronic study, the extract was administered daily to both sex rats at the doses of 100, 200, 400, and 600 mg/kg body weight for 28 consecutive days. Body weight was measured weekly, while hematological, biochemical, and histopathological parameters were analyzed after euthanize. Aqueous extract of Ficus vogelii at all tested doses didn’t produced any mortality or significant change on the body weight and relative weight of rats on acute and sub-chronic studies. The lethal dose 50 was estimated greater than 5000 mg/kg (DL50˃5000 mg/kg). Hematological parameters were recorded non-significant in all treated rats. Aqueous extract at 600 mg/kg significantly changed transaminases and alkaline phosphatase activities, these changes were reversible in satellites. The concentrations of bilirubin was increased at 200 and 600 mg/kg in male rats, at 100, 400 mg/kg in female rats. The levels of lipids markers didn’t changed, except the significant decrease of LDL-cholesterol. Histological examination didn’t showed any change in the architecture of the liver and kidney of rats treated compared to control. Thus aqueous extract of Ficus vogelii stem bark didn’t produced adverse effects in rats after oral acute and sub-chronic treatment.

Warfarin (4-hydroxy coumarin) is Vitamin K (VK) antagonist that inhibits Vitamin K-dependent (VKD) processes, such as blood coagulation. It exerts influence on some non-VKD-related activities as well. In this study, the effect of subacute (30-day) oral warfarin (2 mg L-1 and 1 mg L-1) intake on hematological parameters was examined in two rat strains, Albino Oxford (AO) and Dark Agouti (DA), that differ in their sensitivity to certain chemicals. Greater susceptibility to anticoagulant effect of 2 mg L-1 of warfarin was observed in AO rats and was associated with an increase in relevant hematological parameters in this strain. Although both strains responded to 2 mg L-1 of warfarin with quantitative changes in peripheral blood leukocytes differential bone marrow and lung responses were observed. Strain-related differences in proinflammatory activity of peripheral blood granulocytes and in mononuclear cell IFN-? production were observed. Recognition of differences in quantitative and qualitative effects of oral warfarin on processes other than hemostasis might be of relevance for those humans who are on warfarin therapy.

The effect of the drug Delcid 7.5 ® on the clinical, hematological and biochemical parameters of rabbits of the New Zealand breed, 6 months of age, when used in doses of 2 ml or 4 ml. Three times with a cutaneous application along the vertebral column from the head to the tail. The conducted studies allow us to conclude that after applying the drug in these doses for 3 days, there were no external signs of intoxication in rabbits. All the animals of the experimental groups were active. The reaction to external stimuli is preserved. Hematological parameters of peripheral blood (number of erythrocytes, leukocytes, hemoglobin, color index, the average hemoglobin content of PG in erythrocytes, mean corpuscular volume, the exponent of anisocytosis of red blood cells, etc.) of the experimental group after treatment in 5, 15, 25 days had no significant differences from those in the control group, this suggests that the applied drug to the skin along the spine from the withers to the rump at a dose of 2 and 4 ml has no Toxicological effect on peripheral blood. The leukogram of the peripheral blood of rabbits when using the drug did not differ from the control parameters. The analysis of biochemical parameters (activity of aminotransferase, alkaline phosphatase, lactate dehydrogenase, creatinine, urea, glucose, total protein, bilirubin, etc.) of the blood of the experimental groups when applying the drug Delcid 7.5 ® along the spinal column at the maximum therapeutic dose did not reveal statistically significant differences from the control, which indicates that the drug does not have a genotoxic effect, does not interfere with the kidneys and metabolism in the body of rabbits. The results of the conducted studies show that the insecticide-acaricide drug Delcid 7.5® for veterinary use, developed by NVC Agrovetzashchita LLC, is safe for rabbits, and therefore it can be recommended for studying the effectiveness of acarosis in rabbits and other animal species.

At present, gold nanoparticles (GNPs) are widely used in biomedical applications such as cancer diagnostics and therapy. Accordingly, the potential toxicity hazards of these nanomaterials and human safety concerns are gaining significant attention. Here, we report the effects of prolonged peroral administration of GNPs with different sizes (2, 15 and 50[Formula: see text]nm) on morphological changes in lymphoid organs and indicators of peripheral blood of laboratory animals. The experiment was conducted on 24 white mongrel male rats weighing 180–220[Formula: see text]g, gold nanospheres sizes 2, 15 and 50[Formula: see text]nm were administered orally for 15 days at a dosage of 190[Formula: see text][Formula: see text]g/kg of animal body weight. The GNPs were conjugated with polyethylene glycol to increase their biocompatibility and bioavailability. The size-dependent decrease of the number of neutrophils and lymphocytes was noted in the study of peripheral blood, especially pronounced after administration of GNPs with size of 50[Formula: see text]nm. The stimulation of myelocytic germ of hematopoiesis was recorded at morphological study of the bone marrow. The signs of strengthening of the processes of differentiation and maturation of cellular elements were found in lymph nodes, which were showed as the increasing number of immunoblasts and large lymphocytes. The quantitative changes of cellular component morphology of lymphoid organs due to activation of migration, proliferation and differentiation of immune cells indicate the presence of immunostimulation effect of GNPs.

Bisphenol-A (BPA) is one of the highest volume chemicals produced world-wide and used in the manufacture of plastics and epoxy resins that are pervasive in our environment and daily lives. The present research was carried out to investigate the effects of two different doses of Bisphenol-A (BPA) on the body weight, hematological parameters and patho-physiological changes of kidney in mice. For this study, fifteen mice, 6 to 8 weeks of age with an average bwt 27.10±0.5 gm, were randomly divided into three groups (n= 5). Group A (control) received only normal mouse pellet while group B and group C received pellet mixed with BPA @ 50 mg and 100 mg / kg bwt daily for 12 weeks, respectively. At the end of the experiment, blood and tissues were collected and processed for hematological and histopathological examination. Results showed that BPA- treated mice caused significant elevation (p<0.01) in weight gain even treated with low dose (50mg) of BPA. The mice exposed to high dose of BPA (100 mg) showed marked reduction (p<0.05) in total erythrocyte count (TEC), significant decreased (p<0.01) in hemoglobin concentration (Hb) and packed cell volume (PCV). Histopathological alterations were detected in the kidneys of BPA-treated mice. In conclusion, this study suggested that BPA exerts deleterious impacts on hematological parameters including association with renal injuries. Asian J. Med. Biol. Res. December 2020, 6(4): 635-640

Introduction. Technical products that are part of pesticides recommended for use in agriculture must undergo a comprehensive sanitary and Toxicological examination, which is the basis for preventing the adverse effects of pesticides on the health of workers and the population, as well as on the sanitary state of the environment. Purpose of research - the study of the biological effect of the technical product derived triazolinthionov, with its repeated oral intake in mammals (rats), justification of the permissible daily dose (DSD) for humans. Material and methods. Chronic (12 months) experiment was conducted on male rats with a body weight of 200-210 g tested doses: 5.0; 50.0 and 500.0 mg/kg body weight (1 control and 3 experimental groups and 20 individuals each). In the dynamics of the experiment, we observed the condition and behavior of animals, water and food consumption, fixed the timing of death, recorded changes in body weight, physiological, biochemical and hematological parameters. Results. It was found that the dose of 5.0 mg/kg body weight does not cause significant changes in all studied parameters, doses of 50.0 and 500.0 mg/kg body weight had a polytropic effect on the body of experimental animals. Discussion. The studied technical product at repeated intake in doses of 50,0 and 500,0 mg/kg of body weight causes changes in the state of the Central nervous system of animals (statistically significant changes in SPP, total activity, path length, rest time), as well as changes in carbohydrate, lipid, and lipoprotein metabolism in the body, as evidenced by statistically significant changes in biochemical and hematological indicators. Consequently, doses of 50,0 and 500,0 mg/kg of body weight have a polytropic effect on the body of male rats and are effective. The dose of 5.0 mg/kg of body weight, when administered in animals of the experimental group in comparison with animals of the control group, there are no changes in all the studied parameters throughout the experiment, is accepted as invalid. On the basis of an inactive dose of 5.0 mg/kg of body weight and a reserve factor of 100, we have scientifically justified DSD for humans at the level of 0.05 mg/kg. Conclusion. Studies have shown that long-term repeated oral administration of the studied product into the body of animals (male rats) at a dose of 5.0 mg per 1 kg of body weight does not cause statistically significant changes in all the studied parameters, so the indicated dose is invalid. Doses of 50,0 and 500,0 mg/kg MT have a polytropic effect on the body of male rats and are effective. DSD for humans at the level of 0.05 mg/kg is justified based on the inactive dose at the level of 5.0 mg per 1 kg of body weight, established in a 12-month chronic experiment conducted on male rats, and the reserve coefficient of 100 (taking into account the unexpressed specific and long-term effects).

AbstractThe purpose of this study was to evaluate the beneficial effects of magnesium (Mg) supplementation upon carbon tetrachloride (CCl4) toxicity. Our study was carried out on 24 Wistar male rats divided into 4 batches. During a 6 week period, one group served as a control, two groups received Mg (after 4 weeks one of these groups was then treated with CCl4), and a final group was treated with CCl4 only. Under our experimental conditions, CCl4 poisoning resulted in oxidative stress indicated by a significant increase in lipid peroxidation level in renal tissues. The blood levels of creatinine and urea increased while the blood level of uric acid and proteins decreased. CCl4 also induced an increase in superoxide dismutase (SOD) and glutathione peroxidase (GPX) activity in kidneys, in the number of red blood cells (RBC), and in hemoglobin content (Hb) and mean cell hemoglobin concentration (MCHC). However, white blood cell count (WBC), platelet count (Pl) and catalase activity (CAT) all decreased significantly. Treatment with Mg was found to alleviate most of CCl4-induced damage by decreasing lipid peroxidation and by correcting changed hematological parameters, and catalase, glutathione peroxidase and superoxide-dismutase activities. The results provide strong evidence that Mg supplementation is beneficial in protecting the kidneys from CCl4 toxicity.

In this work there was investigated the effect of two nonsteroidal antiinflammatory drugs (NSAIDs), acetylsalicylic acid or aspirin (nonselective cyclooxygenase inhibitor - COX1 i COX2) and meloxicam (selective cyclooxygenase inhibitor - COX2) on certain hematological parameters in rats. The objective of the work was to determine whether (and to which extent), these drugs, after multiple peroral application, influence erythrocyte number, concentration of hemoglobin, hematological indices (mean corpuscular value - MCV; mean concentration of hemoglobin in erythrocytes - MCH; mean corpuscular hemoglobin concentration - MCHC), hematocrit, number of platelets, leukocytes, neutrophilic leukocytes, lymphocytes and monocytes. The experiment was conducted in in vivo conditions on 70 clinically healthy Wistar strain male rats, 10 to 12 weeks of age and body weight 250 to 300 g. The rats were divided into seven groups and they were daily perorally (by probe) given aspirin (ASCOPIR) at doses of 30, 40 and 80 mg/kg b.m. (I, II and III groups), or meloxicam (METACAM) at doses of 100, 125 and 250 ?g/kg b.m. (IV, V and VI groups), for seven days. The seventh group was a control one and they were given only saline. The obtained results showed that: acetylsalicylic acid in maximum dose tested (80 mg/kg b.m.) statistically significantly reduced the number of platelets (p<0,05), the number of leukocytes (p<0,05), the number of lymphocytes (p<0,05) and the number of monocytes (p<0,05), while on the other side, meloxicam in maximum dose tested (250 ?g/kg), statistically significantly reduced the mean corpuscular value (MCV), and increased the number of platelets (p<0,05), relative to the control value.
