AB  - The present study aimed to examine the biological activity and cardioprotective potential of Trametes versicolor heteropolysaccharides (TVH) in a rat model of metabolic syndrome (MetS). This study included 40 Wistar rats divided into 5 groups: CTRL—healthy non-treated rats; MetS—non-treated rats; and H-TV, M-TV and L-TV-rats with MetS treated with either 300, 200 or 100 mg/kg TVH per os for 4 weeks. After finishing the treatment, we conducted an oral glucose tolerance test (OGTT), hemodynamic measurements and the animals were sacrificed, hearts isolated and subjected to the Langendorff technique. Blood samples were used for the determination of oxidative stress parameters, lipid status and insulin levels. We showed that α-amylase inhibition was not the mode of TVH antidiabetic action, while TVH showed a moderate inhibition of pathogenic microorganisms’ growth (MIC 8.00 mg·mL−1; MBC/MFC 16.00 mg·mL−1). H-TV and M-TV significantly reduced the level of prooxidants (O2−, H2O2, TBARS; p < 0.05), increased antioxidants activity (SOD, CAT, GSH; p < 0.05), reduced blood pressure (p < 0.05), improved glucose homeostasis in the OGTT test (p < 0.05), and ejection fraction (p < 0.05) and cardiac contractility (p < 0.05) compared to MetS (p < 0.05). Moreover, TVH treatment normalized the lipid status and decreased insulin levels compared to MetS rats (p < 0.05). The obtained results demonstrated that the TVH may be considered a useful agent for cardioprotection in MetS conditions.

AB  - Polycystic ovary syndrome (PCOS) is a frequent multifactorial
endocrinopathy affecting women in the reproductive period, often associated with infertility and
metabolic disorders. The use of animal models helps to better understand etiopathogenesis, enabling
the examination of the effects of certain drugs in order to discover the best possible therapeutic
approach. We tried to investigate the additional effect of estradiol-valerate (EV) and high-fat diet
(HFD) in female rats to explore PCOS-related alterations with special focus on oxidative stress.
Materials and Methods: Animals were divided into three groups: control group (CTRL, n = 6), estradiolvalerate
group (EV, n = 6), and estradiol-valerate group on HFD (EV + HFD, n = 6). PCOS was
induced by single subcutaneous injection of long-acting EV in a dose of 4 mg/per rat. We tried to
improve the metabolic characteristics of the PCOS animal model by adding HFD, so the CTRL and
EV group had a regular diet, while the EV + HFD group had HFD during the induction period of
60 days. Results: We observed alterations of anthropometric parameters and hormonal disturbances,
along with estrus cycle impairment reassembly to obese-type PCOS phenotype. Moreover, glucose
metabolism was impaired after addition of HFD to EV protocol, contrary to EV administered alone.
Histological analysis confirmed more numerous cystic follicles after the combination of EV and HFD
protocol. The alterations of oxidative stress markers could be related to and serve as the mechanistic
base for development of PCOS-related endocrine, reproductive, and metabolic properties. Conclusions:
The additive effect of EV and HFD was obvious in the majority of the parameters observed. Our
study strongly demonstrated metabolic as well as reproductive properties of PCOS in rats.

AB  - The study included 32 Wistar albino male rats, 10 weeks old, divided into 4 groups: control (T-N-), nandrolone (T-N+), swimming (T+N-) and swimming plus nandrolone (T+N+) groups. The T+ positive groups swam for 4 weeks, 1 hour/day, 5 days/week. The N+ positive groups received nandrolone decanoate (20 mg/kg b.w.) once per week, subcutaneously. Five micrometer thick sections were immunohistochemically stained, while LH and FSH cells were exposed to the morphometric analysis. Circulating level of LH, FSH and testosterone were measured. Body weight did not significantly decrease in all experimental groups compared to control. Absolute pituitary weights were decreased in T-N+ and increased in T+ positive groups. Relative pituitary weights were increased in all experimental groups compared to control. Volume density of LH cells was decreased for 48% in T-N+, for 22% in T+N- and for 35% in T+N+ group. Number of LH cells on mm2 was decreased for 36% in T-N+, for 3% in T+N- and for 27% in T+N+ group. Volume densities of FSH cells were decreased for 39% in T-N+, for 5.5% in T+N- and for 30% in T+N+ compared to control. Number of FSH cells was decreased for 13% in T-N+, for 1% and 15% in T+N+ group compared to control. Serum levels of LH were decreased in N+ positive groups, while FSH level was increased in T+N- group. Serum level of testosterone was increased in all experimental groups compared to control value. Nandrolone alone or combined with swimming decreased morphometric parameters of gonadotropic cells.

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. Both types of training caused significant hypertrophy of the left ventricle myocardium in normotensive and hypertensive rats

AB  - The aim of this study was to investigate the immunohistomorphometric parameters of follicle-stimulating hormone (TSH) and luteinizing hormone (I.H) cells after testosterone application in an animal model of the andropause. Middle-aged Wistar rats were divided into orchidectomized (Or) and testosterone treated orchidectomized (OrxT) groups. Testosterone propionate (5 mg/kg b.m. (day) was administered for three weeks. while Or group received the vehicle alone.
Immunohistochemically stained FSH and I cells were subjected to the morphometric and optical density-related analysis. while circulating concentration of testosterone was measured by the immunoassay. Serum concentration of testosterone was increased (ps0.05) by 24 fold in comparison with Orx group.
Testosterone treatment did not cause significant changes of body mass or absolute and relative pituitary weights compared to Or group. The volume of FSH and LH cells was decreased (ps0.05) by 51.3% and 56.6% respectively, in comparison with Or rats. Relative volume density of FSI and LE cells was also decreased (p<0.05) by 54.0% and 72.8% respectively, compared to Or group. Results related to the optical density of gonadotropic cells were in line with the morphometric findings i.e. this parameter of FSH and LH cells was decreased (P«0.05) by 25.7% and 16.2% respectively, in comparison with Or rats. In conclusion. applied testosterone decreased morphometric parameters and optical density of gonadotropic cells in Or rats.

abstract = "The aim of this study was to investigate the immunohistomorphometric parameters of follicle-stimulating hormone (TSH) and luteinizing hormone (I.H) cells after testosterone application in an animal model of the andropause. Middle-aged Wistar rats were divided into orchidectomized (Or) and testosterone treated orchidectomized (OrxT) groups. Testosterone propionate (5 mg/kg b.m. (day) was administered for three weeks. while Or group received the vehicle alone.
Immunohistochemically stained FSH and I cells were subjected to the morphometric and optical density-related analysis. while circulating concentration of testosterone was measured by the immunoassay. Serum concentration of testosterone was increased (ps0.05) by 24 fold in comparison with Orx group.
Testosterone treatment did not cause significant changes of body mass or absolute and relative pituitary weights compared to Or group. The volume of FSH and LH cells was decreased (ps0.05) by 51.3% and 56.6% respectively, in comparison with Or rats. Relative volume density of FSI and LE cells was also decreased (p<0.05) by 54.0% and 72.8% respectively, compared to Or group. Results related to the optical density of gonadotropic cells were in line with the morphometric findings i.e. this parameter of FSH and LH cells was decreased (P«0.05) by 25.7% and 16.2% respectively, in comparison with Or rats. In conclusion. applied testosterone decreased morphometric parameters and optical density of gonadotropic cells in Or rats.",

AB  - Advanced age is frequently entwined with the adrenal cortex function impairment, glucocorticoid excess and following metabolic syndrome.
Also, age-dependent
disturbancies in aldosterone secretion and Na*/K homeostasis at least partly underlie the hypertension issues. Classical therapeutic approach in the treatment of some menopausal symptoms implies administration of estradiol or calcium, or their combination. Herein, we aimed to investigate the effects of chronic treatment with estradiol and calcium on some adrenal gland parameters in the ageing female rat model. Middle-aged (14-month-old) female Wistar rats were treated with estradiol dipropionate (EDP; 0.625 mg/kg b.m.) and calcium glucoheptonate (Ca; 11.4 mg/kg b.m.) daily for two weeks, while control ruts received vehicle alone by the same schedule. Combined treatment caused the decrease (p<0.05) of body mass by 21.5%, while the absolute and relative adrenal gland weights were increased (p<0.05) by16.2% and 43.8% respectively, compared to the adequate control values. The absolute adrenal gland volume, after treatment with EDP and Ca in the combination, was also increased (12.1%; p<0.05), in comparison with control group.
In parallel with that, circulating aldosterone was elevated (p<0.05) by 50.0%, compared to the control levels. However, combined treatment with EDP and Ca insignificantly (P>0.05) affected Na* and K' blood concentrations. It can be concluded that simultaneous estradiol ants calcium administration to middle-aged female rats enlarges the adrenal glands and have stimulatory influence on the mineralocorticoid output, which may represent unwanted effect from the perspective of blood pressure regulation.
