Evaluation of supramolecular complex of fenbendazole effect on embryonic development
The purpose of the research is to study the embryotropic effect of supramolecular complex of fenbendazole (SMΠ‘F).Materials and methods. The experiment to assess the embryotropic properties of SMCF was carried out on 40 white female and 20 male rats in accordance with the Guidelines for the experimental (preclinical) study of new pharmacological substances. Pregnant female rats were divided into 3 experimental and one control groups. SMCF was administered intragastrically on the 1β6 days of embryogenesis (group 1); on the 7β14 days (group 2) and on the 15β19 days (group 3) in three times therapeutic dose β 6,0 mg/kg of active substance. The animals of the control group received saline from the first to the 19th days of pregnancy. Rats were euthanized on the 20th day of pregnancy. The uterus with fetuses was removed after laparotomy, the number of corpora lutea, implantation sites, the number of living, dead and resorbed fetuses were recorded, the weight and diameter of the placenta were determined. The embryos were examined, weighed, the craniocaudal sizes were determined, the levels of total embryonic, preimplantation and postimplantation embryo death were calculated. The fetuses were examined for abnormalities of internal organs and changes in the skeletal system according to the methods of J. G. Wilson (1965) and A. B. Dawson (1926), modified in the department of embryology of the IEM of the USSR Academy of Medical Sciences.Results and discussion. As a result, SMCF does not induce toxic effects on the fetus: mortality rates, size and weight of embryos were at the level of the control group in a threefold therapeutic dose 6,0 mg/kg at intragastric administration on the 1β6; 7β14 and 15β19 days of pregnancy. SMCF did not cause external and internal malformations

The purpose of the research is to study the immunotoxic properties of the supramolecular complex of fenbendazole (CMF).Materials and methods. The study of the immunotoxic properties of SMF was performed using the agglutination reaction and delayed-type hypersensitivity. In each experimental group, there were 7β8 CBA Γ C57BL / 6 mice weighing 16β18 g. The CMF was administered once intragastrically at a therapeutic dose of 20 mg/kg for the active substance, in a tenfold dose β 200 mg/kg, the basic drug β fenbendazol asked in a tenfold dose of 20 mg/kg. Control groups of animals received starch paste. Then the mice were immunized intraperitoneally with a 3 % suspension of sheep erythrocytes (test antigen) and distributed into 8 groups. The effect of drugs on antibody production was determined in the hemagglutination reaction, the antibody titer in the serum in the microvariant of the direct hemagglutination reaction with the calculation of the reaction index. The effect of the drug on cellular immunity was established in a delayed-type hypersensitivity reaction (DTH) to sheep erythrocytes.Results and discussion. The introduction of the tested drugs had no inhibitory effect on antibody production in mice of the experimental groups: 6.5Β±0.22; 6.17Β±0.47 and 7.75Β±0.25 (log2) compared with the control β 7.67Β±0.21 (log2). Reaction indices were respectively 0.85; 0,80 and 1,01. Oral administration of a single CMF in therapeutic (20 mg/kg) and in a tenfold therapeutic dose (200 mg/kg) did not affect the cellular level of immunity. The shifts in the inflammatory response index in animals were 9.05Β±3.47 and 10.05Β±2.25% respectively. The introduction of the basic drug stimulated the reaction of HRT, which was manifested by an increase in the inflammation index (21.06Β±3.32%) compared with the control group (9.27Β±3.91%).Π¦Π΅Π»Ρ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΠΉ: ΠΈΠ·ΡΡΠ΅Π½ΠΈΠ΅ ΠΈΠΌΠΌΡΠ½ΠΎΡΠΎΠΊΡΠΈΡΠ΅ΡΠΊΠΈΡ

Gender differences in the pharmacological actions of pegylated glucagon-Like peptide-1 on endothelial progenitor cells and angiogenic precursor cells in a combination of metabolic disorders and lung emphysema
In clinical practice, the metabolic syndrome (MetS) is often associated with chronic obstructive pulmonary disease (COPD). Although gender differences in MetS are well documented, little is known about sex-specific differences in the pathogenesis of COPD, especially when combined with MetS. Consequently, it is not clear whether the same treatment regime has comparable efficacy in men and women diagnosed with MetS and COPD. In the present study, using sodium glutamate, lipopolysaccharide, and cigarette smoke extract, we simulated lipid metabolism disorders, obesity, hyperglycemia, and pulmonary emphysema (comorbidity) in male and female C57BL/6 mice. We assessed the gender-specific impact of lipid metabolism disorders and pulmonary emphysema on angiogenic precursor cells (endothelial progenitor cells (EPC), pericytes, vascular smooth muscle cells, cells of the lumen of the nascent vessel), as well as the biological effects of pegylated glucagon-like peptide 1 (pegGLP-1) in this experimental paradigm. Simulation of MetS/COPD comorbidity caused an accumulation of EPC (CD45βCD31+CD34+), pericytes, and vascular smooth muscle cells in the lungs of female mice. In contrast, the number of cells involved in the angiogenesis decreased in the lungs of male animals. PegGLP-1 had a positive effect on lipids and area under the curve (AUC), obesity, and prevented the development of pulmonary emphysema. The severity of these effects was stronger in males than in females. Furthermore, PegGLP-1 stimulated regeneration of pulmonary endothelium. At the same time, PegGLP-1 administration caused a mobilization of EPC (CD45βCD31+CD34+) into the bloodstream in females and migration of precursors of angiogenesis and vascular smooth muscle cells to the lungs in male animals. Gender differences in stimulatory action of pegGLP-1 on CD31+ endothelial lung cells in vitro were not observed. Based on these findings, we postulated that the cellular mechanism of in vivo regeneration of lung epithelium was at least partly gender-specific. Thus, we concluded that a pegGLP-1-based treatment regime for metabolic disorder and COPD should be further developed primarily for male patients
Effects of <i>Trichinella spiralis</i> and <i>Echinococcus multilocularis</i> extracts after single and multiple injections on mitosis and hematological and biochemical parameters of mice
The purpose of the research is to study effects of Trichinella spiralis and Echinococcus multilocularis extracts on mitosis in a bone marrow cell population, and on hematological and biochemical blood parameters of mice after single and multiple intraperitoneal injections.Materials and methods. The experiment was conducted on outbred male mice. The T. spiralis and E. multilocularis extracts were administered intraperitoneally once or multiple times daily for 10 days at a dose of 80 ΞΌg/mouse. Bone marrow cell isolation, microscopic preparations, mitotic index and individual stage determination were made as described in the literature (Ford C. E., Hamerton J. L., 1956). The mouse main peripheral blood parameters were determined with a MicroCC-20 Plus hematological analyzer, and the leucogram was determined by a conventional method. Biochemical blood parameters of the mice were determined with a Clima MC-15 analyzer.Results and discussion. The T. spiralis and E. multilocularis extracts after a single intraperitoneal injection at a dose of 80 ΞΌg/ mouse had a pronounced negative effect on the mouse bone marrow cell mitosis with the cell division terminated in the metaphase and a decreased proportion of other mitosis stages. Characteristics were detected of the effects made by the T. spiralis and E. multilocularis extracts on the mouse bone marrow cell mitosis after multiple administration for 10 days. In the reinjection mode of the test extracts to the mice, hematological and biochemical parameters did not change

Objective of research: Determination of the efficiency of 5% concentration Diminazene aceturate at the dose of 0.25 mg/kg body in combination with polyethylene glycol solution applied against piroplasmidosis in cattle.Materials and methods: Trial of the new method of prolonged chemoprevention was carried out in one of the farms of Dagestan, which is unfavorable for piroplasmidosis. Aceturate contained in this drug rapidly inhibits DNA in cells of blood parasites, which leads to their death within several hours. Diminazene aceturate proved to be effective against piroplasmidosis, babesiosis, taleriosis, hemosporidosis of animals. The experiment was conducted on 30 head of cattle divided into 3 groups 10 head in each. Animals of two groups received the preparation and prolongator at the dose of 0,25 mg/kg in the 15% aqueous solutions of polyethylene glycols (PEG), and at the dose of 0,25 mg/kg in the 20% aqueous solutions; the third group served as aΒ control (received the preparation without prolongator). Efficacy of the method was estimated by periodic examination of blood smears from experimental animals for plasmodia in erythrocytes and synchronous measurement of body temperature of animals.Results and discussion: It was found that the method of prolonged chemoprophylaxis applied against piroplasmidosis in animals (at the dose of 5 ml per 100 kg body weight, 6 times every 25 days) enables disease prevention during the whole disease season. Such method allows reducing the number of treatments from 24 to 12-13 times in a season. In addition, data on the distribution of hemosporidia infections among the cattle in the Republic of Dagestan were clarified.Π¦Π΅Π»Ρ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΡ β ΠΈΠ·ΡΡΠ΅Π½ΠΈΠ΅ ΡΡΡΠ΅ΠΊΡΠΈΠ²Π½ΠΎΡΡΠΈ ΠΏΡΠ΅ΠΏΠ°ΡΠ°ΡΠ° ΠΠΠ¦ (Π΄ΠΈΠΌΠΈΠ½Π°ΡΠ΅Π½Π° Π°ΡΠ΅ΡΡΡΠ°Ρ) Π² ΡΠΎΡΠ΅ΡΠ°Π½ΠΈΠΈ Ρ 20%-Π½ΡΠΌ ΡΠ°ΡΡΠ²ΠΎΡΠΎΠΌ ΠΏΠΎΠ»ΠΈΡΡΠΈΠ»Π΅Π½Π³Π»ΠΈΠΊΠΎΠ»Ρ ΠΏΡΠΈ ΠΏΠΈΡΠΎΠΏΠ»Π°Π·ΠΌΠΈΠ΄ΠΎΠ·Π°Ρ

The purpose of the research is to study effects of Trichinella spiralis and Echinococcus multilocularis extracts on mitosis in a bone marrow cell population, and on hematological and biochemical blood parameters of mice after single and multiple intraperitoneal injections.Materials and methods. The experiment was conducted on outbred male mice. The T. spiralis and E. multilocularis extracts were administered intraperitoneally once or multiple times daily for 10 days at a dose of 80 ΞΌg/mouse. Bone marrow cell isolation, microscopic preparations, mitotic index and individual stage determination were made as described in the literature (Ford C. E., Hamerton J. L., 1956). The mouse main peripheral blood parameters were determined with a MicroCC-20 Plus hematological analyzer, and the leucogram was determined by a conventional method. Biochemical blood parameters of the mice were determined with a Clima MC-15 analyzer.Results and discussion. The T. spiralis and E. multilocularis extracts after a single intraperitoneal injection at a dose of 80 ΞΌg/ mouse had a pronounced negative effect on the mouse bone marrow cell mitosis with the cell division terminated in the metaphase and a decreased proportion of other mitosis stages. Characteristics were detected of the effects made by the T. spiralis and E. multilocularis extracts on the mouse bone marrow cell mitosis after multiple administration for 10 days. In the reinjection mode of the test extracts to the mice, hematological and biochemical parameters did not change.Π¦Π΅Π»Ρ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΠΉ β ΠΈΠ·ΡΡΠ΅Π½ΠΈΠ΅ ΠΎΡΠΎΠ±Π΅Π½Π½ΠΎΡΡΠ΅ΠΉ Π²Π»ΠΈΡΠ½ΠΈΡ ΡΠΊΡΡΡΠ°ΠΊΡΠΎΠ² Trichinella spiralis ΠΈ Echinococcus multilocularis Π½Π° ΠΌΠΈΡΠΎΠ· Π² ΠΏΠΎΠΏΡΠ»ΡΡΠΈΠΈ ΠΊΠ»Π΅ΡΠΎΠΊ ΠΊΠΎΡΡΠ½ΠΎΠ³ΠΎ ΠΌΠΎΠ·Π³Π°, Π° ΡΠ°ΠΊΠΆΠ΅ Π³Π΅ΠΌΠ°ΡΠΎΠ»ΠΎΠ³ΠΈΡΠ΅ΡΠΊΠΈΠ΅ ΠΈ Π±ΠΈΠΎΡ
