AB  - BACKGROUND During the last decades, the abuse of anabolic androgenic steroids (AASs) has become popular among professional and recreational athletes. The abuse of AASs leads to decreased levels of sex hormones, but the available literature a gives very small pool of data regarding the effects of swimming alone or combined with AASs on testicle tissue. The aim of this study was to investigate the effects of four-week administration of nandrolone decanoate and swimming training alone or in combination on morphometric parameters, androgen receptor (AR) and redox state in testicle tissue. The study included Wistar albino male rats, 10 weeks old, classified into 4 groups: control (T-N-), nandrolone (T-N+), swimming training (T+N-) and swimming training with nandrolone (T+N+). The rats from nandrolone (N+) groups received nandrolone decanoate 20 mg/kg b.w.once per week. The rats from training (T+) groups, swam 1 h/day 5 days/week. The isolated testicles were measured, left testicles were routinely processed for histological analysis, while right testicles were homogenized and prepared for the analysis of the following oxidative stress biomarkers: index of lipid peroxidation (TBARS), nitrites, catalase, superoxide dismutase (SOD), and reduced glutathione (GSH). RESULTS Diameter, as well as cross-section area of seminiferous tubules were decreased by 10 % and 21 % (respectively) in the T-N+ group and by 15% and 41 % (respectively) in the T+N+ group compared to control. Interstitium of the testicles was decreased in all experimental groups. Reduction of immunoreactivity of AR in T-N+ group was 22 %, in T+N+ group was 9 % compared to control. TBARS levels were increased in T+N- and T+N+ groups. Nitrites were decreased in T+N+ group. Catalase activity was increased in all experimental groups. Swimming alone or combined with nandrolone decreased the level of GSH compared to control. SOD activity was decreased in T-N+ and T+N+ groups compared to control. CONCLUSIONS Nandrolone alone or combined with swimming decreased morphometric parameters and amount of AR in testicle tissue. Changes in the redox state indicate reproductive dysfunction. RéSUMé: CONTEXTE: Au cours des dernières décennies, l’abus de stéroïdes androgéniques anabolisants (SAA) est devenu populaire parmi les athlètes professionnels et récréatifs. L’abus des SAA conduit à une diminution des niveaux d’hormones sexuelles, mais la littérature sur les effets de la natation seule ou combinée avec des SAA sur les tissus testiculaires est encore très limité. Le but de cette étude était d’étudier les effets de l’administration de quatre semaines de décanoate de nandrolone et de l’entraînement à la natation seuls ou en combinaison sur les paramètres morphométriques, le récepteur aux androgènes (RA) et l’état redox dans le tissu testiculaire. L’étude a inclus des rats mâles Wistar albinos, âgés de 10 semaines, classés en 4 groupes: contrôle (T-N-), nandrolone (T-N+), entraînement à la natation (T+N-) et entraînement à la natation avec nandrolone (T+N+). Les rats des groupes nandrolone (N+) ont reçu du décanoate de nandrolone 20 mg/kg p.c. une fois par semaine. Les rats des groupes entraînement (T+) nageaient 1 h/jour 5 jours/semaine. Les testicules isolés ont été mesurés, les testicules gauches ont été systématiquement traités pour l’analyse histologique tandis que les testicules droits ont été homogénéisés et préparés pour l’analyse des biomarqueurs de stress oxydatif suivants: indice de peroxydation lipidique (TBARS), nitrites, catalase, superoxyde dismutase (SOD) et glutathion réduit (GSH). RéSULTATS: Le diamètre, ainsi que la section transversale des tubules séminifères ont été réduits de 10 % et 21 % (respectivement) dans le groupe T-N+ et de 15 % et 41 % (respectivement) dans le groupe T+N+ par rapport au groupe témoin. L’interstitium des testicules était diminué dans tous les groupes expérimentaux. La réduction de l’immunoréactivité de RA dans le groupe T-N+ était de 22 %, dans le groupe T+N+ était de 9 % par rapport au groupe témoin. Les niveaux de TBARS ont augmenté dans les groupes T+N- et T+N+. Les nitrites ont diminué dans le groupe T+N+. L’activité de la catalase a été augmentée dans tous les groupes expérimentaux. La natation seule ou combinée à la nandrolone a réduit le niveau de GSH par rapport au contrôle. L’activité de la SOD était diminuée dans les groupes T-N+ et T+N+ par rapport au contrôle. CONCLUSIONS: La nandrolone seule ou combinée à la natation a diminué les paramètres morphométriques et la quantité de RA dans le tissu testiculaire. Les changements de l’état redox indiquent un dysfonctionnement de la reproduction.

AB  - Galectin-3 (Gal-3) has diverse roles in inflammatory and autoimmune diseases. There is evidence that Gal-3 plays a role in both type 1 and type 2 diabetes. While the role of Gal-3 expression in immune cells invading the pancreatic islets in the experimental model of type 1 diabetes mellitus has been already studied, the importance of the overexpression of Gal-3 in the target β cells is not defined. Therefore, we used multiple low doses of streptozotocin (MLD-STZ)-induced diabetes in C57Bl/6 mice to analyze the effect of transgenic (TG) overexpression of Gal-3 in β cells. Our results demonstrated that the overexpression of Gal-3 protected β cells from apoptosis and attenuated MLD-STZ-induced hyperglycemia, glycosuria, and ketonuria. The cellular analysis of pancreata and draining lymph nodes showed that Gal-3 overexpression significantly decreased the number of pro-inflammatory cells without affecting the presence of T-regulatory cells. As the application of exogenous interleukin 33 (IL-33) given from the beginning of MLD-STZ diabetes induction attenuates the development of disease, by increasing the presence of regulatory FoxP3+ ST2+ cells, we evaluated the potential synergistic effect of the exogenous IL-33 and TG overexpression of Gal-3 in β cells at the later stage of diabetogenesis. The addition of IL-33 potentiated the survival of β cells and attenuated diabetes even when administered later, after the onset of hyperglycemia (12-18 days), suggesting that protection from apoptosis and immunoregulation by IL-33 may attenuate type 1 diabetes.

While the role of Gal‐3 expression in immune cells in experimental type 1 diabetes has been already studied, the importance of the overexpression of Gal‐3 in the target β cells is not defined. We used 10‐12 weeks old C57/BL6 male mice (WT) and C57/BL6 mice with transgenically enhanced Gal‐3 expression in pancreatic β cells (TG). Both groups, received STZ for 5 consecutive days at a dose of 40 mg/kg ip. Mice received exogenous mouse IL‐33 (0.4 μg/injection) i.p., 12th, 14 th, 16 th, and 18 th day after the disease induction. Control animals were treated with intraperitoneally PBS + citrate buffer or IL‐33 + citrate buffer. The overexpression of Gal‐3 protected β cells from apoptosis and attenuated MLD‐STZ induced hyperglycemia, glycosuria and ketonuria. The cellular analysis of pancreata and draining lymph nodes showed that Gal‐ 3 overexpression significantly decreased the number of proinflammatory cells without affecting T regulatory cells. The application of exogenous IL‐33, attenuates the development of disease, by increasing the presence of regulatory FoxP3+ ST2+ cells, and competely abrogate diabetogenesis. We demonstrated the potential synergistic effect of exogenous IL‐33 and TG overexpression of Gal‐3 in β cells Not only enhanced expresion of Gal‐3 in β cells reduced T cell mediated autoimmune inflammatory disease, but also exogenous IL‐33 application had powerful terapeutic effect in TG mice.

Male Wistar albino rats, 10 weeks old, were classified into four groups: control (T−N−), nandrolone (T−N+), swimming training (T+N−), and swimming training with nandrolone (T+N+). The T+ groups swam for 4 weeks, 1 h/day, 5 days/week. The N+ groups received nandrolone decanoate (20 mg/kg) once per week for 4 weeks. Pituitary tissue sections were processed and stained for immunohistochemical analysis and immunofluorescence. The volume density of luteinizing hormone (LH) cells was decreased by 48% in T−N+ and for 35% in the T+N+ group. The volume density of follicle-stimulating hormone (FSH) cells was decreased by 39% in T−N+ and for 30% in T+N+ compared to the control. Nandrolone alone, or combined with swimming training, decreased the number of LH/FSH cells compared to the control. The levels of the immunofluorescent signal of LH/FSH cells were increased in all experimental groups. Nandrolone alone decreased the serum level of LH by 17%, whereas swimming training alone increased FSH levels by 11% compared to the control. Serum levels of testosterone were increased in all experimental groups. Nandrolone alone, or combined with swimming training, decreased immunohistomorphometric parameters of gonadotropic cells, whereas the levels of immunofluorescent signal were increased.

AB  - The aim of this study was to show the effects of moderate-intensity and high-intensity training on morfometric parameters of the left ventricle miocardium in normotensive and hypertensive rats. The study included 32-male Wistar albino and spontaneously hypertensive rats, divided into 6 groups: control normotensive (CTRL), normotensive moderate-intensity training (MIT), normotensive high-intensity training (HIIT), control hypertensive (SHR), hypertensive moderate-The rat ton Mist Roups and by peaterive high since sit training (Si HI days/week, Ih/day, while HIIT groups ran on speed from 35 to 55m/min, 30s in 5 cycles, with a 3 min period of rest between the cycles. After 4-weeks of training, the rats were sacrificed. Heart biopsy specimens were routinely fixed and embedded in paraffin. Five micrometer thick sections were H&E stained. Captured microscopic images were processed by special software for image analysis to quantify the results. Body weights were decreased in all groups of hypertensive rats compared to normotensive rats. Relative heart weights were increased in hypertensive rats compared to normotensive rats. Longitudinal section diameter of cardiac muscle cells was decreased in SHR-MIT group for 13% compared to MIT, while in SHR-HIIT group the same parameter decreased for 17% compared to HIIT. Cross section muscle cell area was decreased: in SHR fl 7% compared to CTRL, in SHR-MIT for 6% compared to MIT, and in SHR-HIIT for 9% in comparison with HIIT.

AB  - Anabolic androgenic steroids (ASs) are synthetic analogs of testosterone. Because of its anabolic effect, in recent decades, AAS became very popular among professional and recreational sports man. The aim of this study was to examine the chronic effects of exercise training alone or combined with supraphysiological doses of nandrolone decanoate (ND) on cardiac muscle of the left ventricle. The study included 32 Wistar albino male rats, divided into 4 groups: control (I-N-), nandrolone (I-N+), exercise training (T+N-) and exercise training plus nandrolone (T+N+) groups. The T+N- and T+N+ group swam for 3 weeks, 1 hour/day, 5 days/week. The T-N+ and T+N+ groups received nandrolone decanoate (20 mg/kg b.w.) once per week, subcutaneously. After 3 weeks of training, the rats were sacrificed. Heart biopsy specimens were routinely fixed and embedded in paraffin.
Five micrometer thick sections were stained with hematoxylin and eosin (H/E). Captured microscopic images were processed by special software for image analysis to quantify results. Our result show that nandrolone alone causes left ventricular wall thickening for 4% (p > 0.05), training alone 14% (p > 0.05) while training combined with nandrolone leads to increased wall thickening for 24% (p < 0.05). Longitudinal section diameter of cardiac muscle cells was increased for 6% (p >0.05), in T-N+ for 23% (p < 0.05), in T*N- and for 33% (p < 0.05) in T+N+ group. Comparison between the experimental groups showed that the largest difference of longitudinal section diameter can be observed between T-N+ and T+N+ (24%; p < 0.05) and the lowest difference was found between T+N- and T#N+ (8%; p > 0.05). Cross section muscle cell area was increased in T-N+ for 7% (p > 0.05), in T+N- for 29% (p < 0.05), in T+N+ for 31% (p < 0.05). Comparison between the experimental groups showed that the difference of cross section area between T-N+ and T+N+ was 22% (p < 0.05) and the lowest, non-significant difference was found between T+N- and T+N+ (1.6%; p > 0.05). Chronic administration of supraphysiological doses of ND alone promote mild cardiac muscle hypertrophy, but only in combination with the exercise training the degree of the cardiac muscle hypertrophy of the left ventricle is significant.

AB  - Anabolic androgenic steroids (AASs) are synthetic analogs of testosterone often used by athletes to increase the skeletal muscle mass. Our goal was to examine the effects of physical activity and physical activity combined with supraphysiological doses of nandrolone on functional morphology of the quadriceps muscle. The study included 32 peripubertal Wistar rats, divided into 4 groups: control (T-N-), nandrolone (T-N+), physical activity (T+N-) and physical activity plus nandrolone (T+N+) groups. The T+N- and T+N+ group swam for 4 weeks, 1 h/day, 5 days/week. The T-N+ and T+N+ groups received nandolone decanoate (20 mg/kg b.w.) once per week, subcutaneously. Subsequently, the rats were sacrificed and muscle specimens were prepared for the processing. Tissue sections were histochemically and immunohistochemically stained, while the image analysis was used for quantification. Longitudinal diameter of quadriceps muscle cells was increased for 21% in T-N+, for 57% in T+N- and for 64% in T+N+ group while cross section muscle cell area was increased in T-N+ for 19%, in T+N- for 47% and in T+N+ group for 59%, compared to the control. Collagen fibers covered area was increased in T-N+ group for 36%, in T+N- for 109% and in T+N+ group for 159%, compared to the control. Erythrocyte depots were decreased in T-N+ group and increased in T+N- and T+N+ group, in comparison with T-N-. VEGF depots were increased in all treated groups. Chronic administration of supraphysiological doses of AASs alone or in combination with physical activity induces hypertrophy and significant changes in the quadriceps muscle tissue structure.

AB  - The aim of this study was to evaluate the effects of chronic NAC administration along with cisplatin on cisplatin-induced cardiotoxicity by means of coronary flow (CF), cardiodynamic parameters, oxidative stress markers and morphological changes in isolated rat heart. Isolated hearts of Wistar albino rats (divided into four groups: control, cisplatin, NAC and cisplatin+NAC group) were perfused according to Langendorff technique at constant coronary perfusion pressure starting at 50 and gradually increased to 65, 80, 95 and 110 cm H2O to evaluate cardiodynamic parameters within autoregulation range. Samples of coronary venous effluent (CVE) were collected for determination of CF and biochemical assays, and heart tissue samples for biochemical assays and histopathological examination. Cisplatin treatment decreased CF and heart rate, and increased left ventricular systolic pressure and maximum left ventricular pressure development rate. Cisplatin increased H2O2 and TBARS, but decreased NO2(-) levels in CVE. In tissue samples, cisplatin reduced pathological alterations in myocardium and coronary vessels, with no changes in the amount of total glutathione, as well as in activity of glutathione peroxidase and glutathione reductase. NAC coadministration, by reducing oxidative damage, attenuated cisplatin-induced changes of cardiodynamic and oxidative stress parameters, as well as morphological changes in myocardium and coronary vasculature.
