Opis:
In this study, the cryoprotective effect of different doses of propolis (P) on bull semen, which has solid pharmacological properties thanks to its rich phenolic components, was investigated biochemically and physiologically. Semen samples were collected from Simmental breed bulls via the artificial vagina and pooled. After dividing into five groups, control (C: no additive) and four different P (200, 100, 50, and 25 μg/mL) groups, the final concentration was diluted to 16×106 per straw. Semen samples were equilibrated at 4°C for approximately 4 hours, then placed in French straws and frozen. After thawing, sperm motility and kinetic parameters, DNA integrity by single-cell gel electrophoresis, sperm abnormalities by liquid fixation, and lipid peroxidation levels by the colorimetric method was analyzed by Computer-Assisted Semen Analyzer. P added to the diluent showed no effect on motility and kinetic parameters at P25 and P50 (p>0.05), while P100 and P200 had a negative effect (p<0.001). The addition of P (25 and 50) showed a treatment effect on tail abnormality compared to C (p<0.05). Especially P50 had a positive effect on tail length, tail DNA, and tail movement, while P100 and P200 caused DNA damage (p<0.001). MDA levels increased in all P dose groups compared to C (p<0.001). This study has clearly demonstrated that P25 and P50 supplements could be used therapeutically to treat sperm tail abnormalities and prevent DNA damage in post-thawed bull sperm.

Opis:
This is the first study to identify 23 protein spots corresponding to 13 proteins in mitochondria isolated from rabbit epididymal spermatozoa. In the group of protein spots identified in stress-induced samples, the abundance of 20 protein spots increased, whereas the abundance of three protein spots (GSTM3, CUNH9orf172, ODF1) decreased relative to the control. The results of this study provide valuable inputs for future research into the molecular mechanisms implicated in pathological processes during oxidative stress (OS).

Opis:
This study was aimed to evaluate the effects of inulin used as prebiotic on the kidney in lipopolysaccharide (LPS)-induced endotoxemia model. Wistar Albino rats were divided into four groups: Control group, LPS (endotoxemia) group, Inulin + LPS group in which LPS (1.5 mg/kg, E. coli, Serotype 0111: B4) was treated after inulin (500 mg/kg) given by gavage for 21 days and Inulin group. The animals were sacrificed 24 h after the last LPS injection. Kidney samples were taken for biochemical and immunohistochemical analyses. Total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), malondialdehyde (MDA) and myeloperoxidase (MPO) values were determined. In addition, kidney sections were stained for inducible nitric oxide synthase (iNOS), tumor necrosis factor (TNF)-α and interleukine-6 (IL-6) expression, and leukocyte infiltration. LPS caused oxidative stress and inflammation. Inulin administration could prevent oxidative stress and lipid peroxidation. Moreover, inulin decreased iNOS, TNF-α and IL-6 expression. However, it did not change the distribution of leukocytes in kidney tissues. These results suggest to promising benefits of inulin as prebiotic in reducing the effects of endotoxemia. Further studies should be conducted to evaluate the capacity of prebiotics in endotoxemia.

Opis:
The aim of this study was to evaluate the efficacy of electroacupuncture in acute and chronic phases of radial and ulnar nerve injuries in histopathological, immunohistochemical and biochemical aspects. In the study, the rabbits were divided into four groups namely acute nerve injury (ANI) group, chronic nerve injury (CNI) group, positive control (PC) group and negative control (NC) group. In the ANI, CNI and PC groups, damage was created on the nervus radialis and nervus ulnaris by applying pressure for 60 seconds using a hemostatic forceps under anesthesia. No damage was created in the NC group. Fifteen sessions of electroacupuncture were applied to the rabbits in the ANI, CNI, and NC groups every other day using LI-4 (Large Intestine Meridian-4, He Gu), LI-10 (Large Intestine Meridian-10, Shou San Li), LR-3 (Liver Meridian-3, Tai Chong), and ST-36 (Stomach Meridian-36, Zusanli) electroacupuncture points. Electroacupuncture was not applied to the rabbits in the PC group. Decapitation was performed under general anesthesia at the end of electroacupuncture applications. After the euthanasia procedure, the samples obtained were evaluated for histopathological, immunohistochemical and biochemical parameters. In conclusion, degenerative foci in the treatment groups were found to be fewer than in the PC group whereas NGF and S-100 immunoreactivity were higher in the treatment groups than in the PC group. Whereas no statistically significant difference was observed between the treatment groups and the NC group in terms of oxidative stress factors, there was a statistically significant difference between the treatment groups and the PC group. In light of all these data, we have concluded that electroacupuncture is an effective treatment method for peripheral nerve injuries.

Opis:
The aim of the present study was to determine the effects of Luteolin (LUT) on semen quality, oxidative stress, apoptosis, acrosomal integrity, mitochondrial membrane potential and dead sperm ratio in rabbits. Ejaculates from six New Zealand rabbits were collected, evaluated and pooled. The pooling was divided into five groups as control (no additive) LUT 25 μM, LUT 50 μM, LUT 100 μM and LUT 200 μM and LUT added. It was then filled into a falcon tube with Tris-based extender at a final concentration of approximately 35 x 106 spermatozoa. Diluated rabbit semen samples were drawn into frozen and thawed. Frozen semen straws were thawed at 37°C in 30 seconds. According to our findings, no statistical difference was found between all doses of luteolin and the control group in the CASA (computer assisted sperm analysis) analysis performed at 4°C. However, total motility, progressive motility and rapid sperm percentage were found to be higher in the frozen and thawed rabbit semen at a dose of LUT 50 μM compared to the other groups (p<0.05). While amplitude of lateral head displacement (ALH) and beat cross-frequency (BCF) values were found at the lowest dose of LUT 200 μM, a statistically significant difference was observed between the other groups. When the flow cytometry results were examined, no statistical difference was found between the rate of dead sperm, acrosomal integrity, mitochondrial membrane potential and apoptosis rate. Morever, the H2O2 percentage was found to be lower in all experimental groups compared to the control group (p<0.001). In conclusion, the addition of LUT in long-term storage of rabbit semen provided a protective effect for spermatozoa with its antioxidative properties against damage caused by cryopreservation.

Opis:
Two theories, one based on the metabolism of inorganic substances, the other on metabolism of organic substances, have played an important role in the explanation of the origin of life. They demonstrate that the original environment of life on Earth was seawater containing micronutrients with structural, metabolic and catalytic activity. It is assumed that the first primitive organisms lived around 3.8 billion years ago and it was also then that the first catalytic reaction involving metal ions occurred. Biological oxidation leading to oxidative stress and cell damage in animals represents one of these types of reactions which are responsible for many animal diseases. The role of prooxidative and antioxidative actions of transition metal ions as well as their neuropathological consequences have therefore been the topic for many research projects. There is hope that metal chelates and antioxidants might prove to be a modern mode of therapy for i.e. neurogenerative diseases. The aim of this review is to show the evolution of scientific knowledge on metal ions, their biological oxidation, and an overview of their role in physiology and in pathological processes.

Opis:
The aim of the study was the evaluation of cadmium effects on the activity of antioxidant enzymes in rat hepatocytes. The studies were conducted with isolated rat hepatocytes incubated for 1 or 2 hours in a modified (deprived of carbonates with phosphates) Williams’ E medium (MWE) in the presence of cadmium chloride (25, 50 and 200 μM). Hepatocytes incubated in the MWE medium without cadmium chloride were used as a control. The application of the modified Williams’ E medium allowed for the appearance of cadmium compounds in a soluble form that is indispensable for suitable estimation of its toxic action. There were evaluated markers of the oxidative stress such as: concentration of thiobarbiturate reactive substances (TBARS) – proportional to the level of lipid peroxidation, concentration of reduced glutathione (GSH), and the activity of antioxidant enzymes, including superoxide dismutase (SOD1 and SOD2), catalase (CAT), total glutathione peroxidase (GSHPx), selenium – dependent glutathione peroxidase (SeGSHPx), glutathione transferase (GST) and glutathione reductase (GSHR). Alterations of antioxidant enzymes activity, the level of TBARS and GSH in isolated rat hepatocytes caused by cadmium in vitro, were shown to depend on the concentration and time of exposure of cells to this metal. The increased level of TBARS and GSH was observed as well as changes in the activity of antioxidant enzymes. The activity of SOD isoenzymes and CAT was increased, whereas GSHPx and GST were decreased. These results indicate that cadmium induces oxidative stress followed by alterations in the cellular antioxidant enzyme system in isolated rat hepatocytes.
