In recent years, researchers have focused on the problem of the dependence of the functioning of various organs and systems on the level of androgens. The effect of long inhibition of testosterone synthesis by triptorelin on liver tissue is poorly understood. The aim of this research was to establish the microscopic organization of rat livers, production of nitric oxide and the intensity of oxidative stress in the rat livers during experimental central deprivation of luteinizing hormone synthesis by diphereline injection on the 270-360th day of the experiment. The experiments were carried out on 30 sexually mature male white rats of the Wistar line. Rats were divided into 2 groups: the control group (10) and the experimental group (20). Animals from the experimental group were subcutaneously injected triptorelin at a dose of 0.3 mg of the active substance/ per kg of body weight for 360 days, while the control group received an injection of saline. It was found that oxidative stress develops in hepatocytes, which is morphologically confirmed by karyopyknosis of the nuclei, oxyphilia of the cytoplasm with the appearance of a significant number of vacuoles in it. The vessels of the microcirculatory bed react with stasis. An increase in the production of superoxide radical anion in rat liver may be due to the absence of an inhibitory effect of testosterone on macrophages and liver mitochondria, which is accompanied by depletion of antioxidant enzymes and the development of oxidative stress. The intensity of biochemical markers of oxidative stress on the 360th day is lower than on the 270th day, which is due to an increase in the activity of antioxidant enzymes and a decrease in the production of reactive oxygen species.

Study Results

A relevant and popular area of research is the protective effect of the bioflavonoid quercetin, which makes it possible to use it to correct testicular dysfunction of various origins. The aim of the study was to determine the effect of quercetin on the microscopic organization of rat testicles, nitric oxide production and the intensity of oxidative stress in rat testicles on the 180th day of the experiment, during experimental central deprivation of luteinizing hormone synthesis caused by triptorelin solution. The experiment was performed on 20 adult male white rats. Rats were divided into 2 groups of 10 animals in each group: control group (I), group with central deprivation of LH synthesis + quercetin (II). Animals from the group with central deprivation of LH synthesis were injected subcutaneously with triptorelin acetate at a dose of 0.3 mg of active substance per kg and quercetin 100 mg per kg of body weight 3 times a week, while the control group was injected with saline. Ultrathin sections made by ultramicrotome were contrasted with 1 % aqueous uranyl acetate and lead citrate according to the Reynolds method and examined by electron microscopy. According to standard methods, the material was poured into paraffin blocks, from which sections with a thickness of 4 μm were made and stained with hematoxylin and eosin. Histological specimens were examined using a Вiorex 3 light microscope with a digital microfilter with software adapted for these studies. All biochemical studies were performed in 10 % of testicular tissue homogenate using a Ulab 101 spectrophotometer. Statistical processing of the study results was performed using Microsoft Office Excel software and Real Statistics 2019 extension. The nonparametric Mann-Whitney test was used to determine the statistical significance of differences between groups. Our study of the interstitial space in the testes of white rats showed the heterogeneity of populations of endocrinocytes and macrophages and the variability of structural and functional parameters. In the tissues of the testes in conditions of prolonged central deprivation of testosterone synthesis develops oxidative stress, which on the 180th day of the experiment leads to the development of edema of the interstitial space, followed by tissue fibrosis. Changes in the polarization of macrophages in our opinion may cause oxidative stress in the testes, as evidenced by increased iNOS activity and decreased arginase activity, but use of quercetin protects rat testicular tissue from oxidative damage caused by triptorelin by increasing direct antioxidant system and effects on the lipoxygenase pathway of arachidonic acid metabolism.

Abstract The aim of the this study was to evaluate the effects of fresh, dried and freeze-dried Centaurea depressa M. Bieb. (Asteraceae) on the oxidant and antioxidant status of the model organism D. melanogaster Meigen (Diptera: Drosophilidae) experimentally. The study was carried out from 2016 to 2019, and plant leaf extracts (0-50 mg/l) were added to insect standard artificial diets. The total protein, protein carbonyl content and glutathione-S-transferase, superoxide dismutase and catalase activities were quantified at the insect’s third larval stage. Our data showed that protein carbonyl content varied from 2.70 nmol/mg protein in the control group to 59.11 nmol/mg protein in the group fed with fresh leaf extract signifying induction of oxidative stress. All extracts increased the levels of all antioxidant enzymes and decreased the amounts of total protein. Meanwhile, the group fed with the freeze-dried extract showed no significant difference in the levels of total protein and protein carbonyl content except at the 50 mg/l concentration of the extract. Moreover, this group had superoxide dismutase and catalase activities 4 to 5 times higher than in the control group. In conclusion, induction of oxidative stress indicates that the fresh form of C. depressa leaves may have potential as a natural pesticide, whereas induction of endogenous antioxidant enzymes by the freeze-dried extract suggest its potential as an antioxidant.

The article presents data on the long-term effect (nine months) of a silicon compound supplied with drinking water – nonahydrate sodium metasilicate (10 mg/l in terms of silicon), on CD68-positive macrophages in the liver and spleen of laboratory rats. Changes in the morphological characteristics of this cell population were found. There was a decrease in the average cell area (in the liver of the control group of rats, the average macrophage area was 179.23±5.94 microns2, and in the group receiving silicon with drinking water – 117.04±3.35 microns2; in the spleen-136.02±3.93 microns2 and 103.44±2.8 microns2, respectively). Macrophages in the liver preparations of the experimental group of rats had a fewer processes and a darker cytoplasmic membrane. The number of macrophages in the liver per unit area was comparable, for the control group of rats it was 18.78±1.24, and for the rats that received with water with the addition of silicon – 19.41±0.75 cells. CD68+ macrophages of the red splenic pulp in laboratory rats that received silicon also underwent the following morphological changes: they were located in a denser way and had fewer processes, while the number of macrophages per unit area was 73.7±2.3 for the control group, 91.6±5.0-for the experimental group, respectively. The distance between them did not change. There was a change in the intensity of CD68 expression on the surface of the cytoplasmic membrane and in the cytoplasm of liver and spleen macrophages. These changes can be interpreted as the adaptive ability of liver and spleen macrophages to silicon introduced with drinking water. Given the heterogeneity of the macrophage population in the liver and spleen, further studies using markers for different subpopulations of macrophages are needed to clarify their role in the response of tissues to silicon supplied with drinking water.

Background/Aim. Chronically induced hypermethioninemia leads to hyperhomocysteinemia which causes oxidative stress, atherogenesis, neurodegeneration and cancer. However, little is known about the acute and subchronic effects of DL-methionine (Met). The aim of study was to assess the effects of acutely and subchronically applied Met on oxidative stress parameters in rat plasma [enzymes: catalase (CAT), glutathione peroxidise (GPx), superoxide dismutase (SOD) and index of lipid peroxidation, malondialdehyde (MDA)], and acetylcholinesterase (AChE) activity in rat cardiac tissue. Methods. The enzymes activities, as well as MDA concentration were evaluated following acute (n = 8) and subchronic (n = 10) application of Met [i.p. 0.8 mmoL/kg body weight (b.w.) in a single dose in the acute overload or daily during three weeks in the subchronic overload]. The same was done in the control groups following application of physiological solution [i.p. 1 mL 0.9% NaCl (n = 8) in the acute overload and 0.1?0.2 mL 0.9% NaCl, daily during three weeks (n =10) in the subchronic overload]. Tested parameters were evaluated 60 minutes after application in acute experiments and after three weeks of treatment in subchronic experiments. Results. There were no difference in homocysteine values between the groups treated with Met for three weeks and the control group. Met administration significantly increased the activity of CAT and GPx after 1 h compared to the control group (p = 0.008 for both enzymes), whereas the activity of SOD and MDA concentrations were unchanged. Subchronically applied Met did not affect activity of antioxidant enzymes and MDA level. AChE activity did not show any change in rat cardiac tissue after 1 h, but it was significantly decreased after the subchronic treatment (p = 0.041). Conclusion. Results of present research indicate that Met differently affects estimated parameters during acute and subchronic application. In the acute treatment Met mobilizes the most part of antioxidant enzymes while during the subchronic treatment these changes seems to be lost. On the contrary, the acute Met overload was not sufficient to influence on the AChE activity, while longer duration of Met loading diminished function of the enzyme. These findings point out that methionine can interfere with antioxidant defense system and cholinergic control of the heart function.

Oxidative stress is an imbalance between free radicals and antioxidants, and is an important etiological factor in the development of hypertension. Recent experimental evidence suggests that subpressor doses of angiotensin II elevate oxidative stress and blood pressure. We aimed to investigate the oxidative stress related mechanism by which a subpressor dose of angiotensin II induces hypertension in a normotensive rat model. Normotensive male Wistar rats were infused with a subpressor dose of angiotensin II for 28 days. The control group was sham operated and infused with saline only. Plasma angiotensin II and H2O2 levels, whole-blood glutathione peroxidase, and AT-1a, Cu/Zn SOD, and p22phox mRNA expression in the aorta was assessed. Systolic and diastolic blood pressures were elevated in the experimental group. There was no change in angiotensin II levels, but a significant increase in AT-1a mRNA expression was found in the experimental group. mRNA expression of p22phox was increased significantly and Cu/Zn SOD decreased significantly in the experimental group. There was no significant change to the H2O2 and GPx levels. Angiotensin II manipulates the free radical-antioxidant balance in the vasculature by selectively increasing O2− production and decreasing SOD activity and causes an oxidative stress induced elevation in blood pressure in the Wistar rat.

The present study was designed to investigate the antioxidant property of l-carnitine (LC) on serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (TH) and testis oxidative stress in streptozotocin (STZ)-induced diabetic rats. The rats were divided into the following groups: group I, control; group II, LC 100 mg/kg/d; group III, diabetic; and groups IV to VI, diabetic rats treated with 50, 100, and 200 mg/kg/d of LC, respectively. Daily injections were given intraperitoneally for 7 weeks. At the end of experimental period, after sacrificing the rats, FSH, LH, TH, total antioxidant capacity (TAC), malondialdehyde (MDA), glutathione (GSH), catalase (CAT), mitochondrial function (MTT), protein carbonyl (PC), and reactive oxygen species (ROS) levels were measured. STZ caused an elevation of MDA, ROS, and PC ( P < .001) with reduction of GSH, CAT, TAC, and MTT ( P < .001) in the serum levels. Group VI had significantly increased FSH, LH, and TH levels versus the untreated diabetic group ( P < .001). Although groups V and VI significantly decreased MDA ( P < .001), PC ( P < .01), and ROS ( P < .01) compared with the untreated diabetic group; only in group VI, the activity of GSH ( P < .001), CAT ( P < .01), TAC ( P < .001), and MTT ( P < .001) significantly increased. The results of the present study suggest that LC decreased diabetes-induced oxidative stress complications and also improved serum level of FSH, LH, and TH by reducing levels of lipid peroxidation and increasing antioxidant enzymes.

Для получения препаратов и добавок, обладающих антиоксидантными свойствами, представляют интерес выжимки томатов, образующиеся при производстве сока прямого отжима с предварительным отделением семян. Проведена сравнительная оценка эффективности функциональных свойств образцов пищевой добавки, полученных из выжимок томатов по различным технологиям: образец добавки 1 получен по технологии, включающей ИК-сушку выжимок, их охлаждение и измельчение; образец добавки 2 – по инновационной технологии, включающей дополнительную предварительную обработку выжимок в ЭМП СВЧ перед ИК-сушкой. Исследования проводили в течение 30 дней на трех группах лабораторных белых крыс: контрольной, животные которой получали стандартный рацион, и двух опытных, в которых животные помимо основного рациона получали при кормлении индивидуально 1 раз в сутки 2 г добавки образца 1 (1-я опытная группа) или образца 2 (2-я опытная группа). Установлено, что степень снижения концентрации ферментов печени АсАт и АлАт в крови животных 2-й опытной группы соответственно на 10,6 и 11,0% выше, чем в крови животных 1-й опытной группы. Степень снижения содержания диеновых коньюгатов, кетодиенов и малонового диальдегида в крови животных 2-й опытной группы была соответственно на 22,1; 10,1 и 12,7% выше по сравнению с аналогичными показателями животных 1-й опытной группы. Таким образом, доказано, что пищевая добавка «Томатная», выработанная по инновационной технологии, проявляет ярко выраженные антиоксидантные и гепатопротекторные свойства, что обеспечивает нормализацию биохимических процессов в организме, повышает его антиоксидантную защиту и препятствует разрушению мембран клеток. For the obtaining of preparations and additives with antioxidant properties, tomato pomace, formed during the production of direct-pressed juice with preliminary separation of seeds, is of interest. A comparative evaluation of the effectiveness of the functional properties of food additive samples obtained from tomato pomace using various technologies was carried out. The sample of additive 1 was obtained using a technology that includes IR drying of pomace, cooling and grinding; the sample of additive 2 was obtained using a technology that includes additional pretreatment of pomace in microwave EMF before IR drying. The studies were carried out for 30 days on three groups of laboratory white rats: a control group, the animals of which were given a standard diet, and two experimental ones, in which the animals, in addition to the main diet, were given individually once a day with 2 g of an additive of sample 1 (1st experimental group) or sample 2 (2nd experimental group). It was found that the degree of decrease in the concentration of liver enzymes AsAt and AlAt in the blood of animals of the 2nd experimental group was respectively 10,6 and 11,0% higher, than in the blood of animals of the 1st experimental group. The degree of decrease in the content of diene conjugates, ketodienes and malondialdehyde in the blood of animals of the 2nd experimental group was higher respectively by 22,1; 10,1 and 12,7% compared with similar indicators of animals of the 1st experimental group. Thus, it is proved that the food additive «Tomatnaya», developed by innovative technology, shows pronounced antioxidant and hepatoprotective properties, which ensures the normalization of biochemical processes in the body, increases its antioxidant protection and prevents the destruction of cell membranes.

In this study the effect of butylated hydroxyanisole (BHA), a phenolic antioxidantused in food on Ferric‐Nitrilotriacetate (Fe–NTA) induced nephrotoxicity is reported. Fe‐NTA (9 mg Fe/kg body weight, intraperitoneally) treatment enhanced the renal microsomal lipid peroxidation and hydrogen peroxide generation to ~2‐2.5 folds compared to saline‐treated control and glutathione levels and the activities of antioxidant enzymes decreased to a range of 2–2.5 fold in kidney. These changes were reversed significantly in animals receiving a pretreatment of BHA. Pretreatment with BHA prior to Fe‐ NTA treatment reduced microsomal lipid peroxidation and hydrogen peroxide generation to 1.3‐1.5 fold compared to control group and glutathione and the activities of antioxidant enzymes increased to a range of 1.5‐2 folds in kidney. Fe‐NTA administration enhanced value of blood urea nitrogen and creatinine to 3.7 and 2.5 fold respectively as compared to their corresponding control group. Administration of Fe‐NTA to rats receiving a pretreatment of BHA led to a significant diminution in both of these values. The results indicate that BHA is a potent chemopreventive agent and suppresses Fe‐NTA induced nephrotoxicity in rats.

Hydroxyapatite Nanoparticles

Abstract Hydroxyapatite nanoparticles (HAP-NPs) are an inorganic component of natural bone and are mainly used in the tissue engineering field due to their bioactivity, osteoconductivity, biocompatibility, non-inflammatory, and non-toxicity properties. However, the current toxicity data for HAP-NPs regarding human health are limited, and only a few results from basic studies have been published. Therefore, the present study was designed to investigate the beneficial role of chitosan nanoparticles (CsNPs) and curcumin nanoparticles (CurNPs) in alleviating nephrotoxicity induced by HAP-NPs in male rats. The results showed that HAP-NPs caused a reduction in antioxidant enzymes and induced lipid peroxidation, nitric oxide production and DNA oxidation. Moreover, HAP-NP administration was associated with intense histologic changes in kidney architecture and immunoreactivity to proliferating cell nuclear antigen (PCNA). However, the presence of CsNPs and/or CurNPs along with HAP-NPs reduced the levels of oxidative stress through improving the activities of antioxidant enzymes. Also, the rats administered the nanoparticles showed a moderate improvement in glomerular damage which matched that of the control group and showed mild positive reactions to PCNA–ir in glomeruli and renal tubules in the cortical and medullary portions. These novel insights confirm that the presence of chitosan and curcumin in nanoforms has powerful biological effects with enhanced bioactivity and bioavailability phenomena compared to their microphase counterparts. Also, they were able to ameliorate the nephrotoxicity induced by HAP-NPs.

Objective: The present study was aimed to evaluate the antihyperglycemic activity and in vivo antioxidant effect of methanolic extract of whole plant of Psydrax dicoccos (MEPD) belonging to the family Rubiaceae.Methods: MEPD was prepared by Soxhlet extraction. Wistar rats weighing (180–200 g) were divided into six groups (n=6), with three doses of 100 mg/kg, 200 mg/kg, and 400 mg/kg of extract. Metformin was used as a standard drug. Diabetes was induced by streptozotocin (STZ) (40–50 mg/kg, i.p) in control group. The animals were treated with different doses of extracts for 21 days, and on the 22nd day, the blood glucose levels along with antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), and lipid peroxidase (LPO) were determined.Results: The phytochemical screening of the extract showed the presence of carbohydrates, phenolics, flavonoids, glycosides, and tannins. The methanolic extract of MEPD at the dose of 200 mg/kg body weight showed a significant reduction in blood glucose levels (**p<0.001) with the value of 151.2 mg/dl on the 22nd day at 8 h. A promising antioxidant effect was also evident from the determination of antioxidant enzymes such as SOD, CAT, and LPO.Conclusion: The P. dicoccos extract revealed a potential effect of antihyperglycemic activity and combating nature on oxidative stress induced by STZ.
