Background: This study aims to investigate the effects of blunt lung trauma performed in experimental rat model on lung tissue and blood as well as proinflammatory cytokines, oxidant-antioxidant enzymes and histopathological parameters after Ngamma-nitro-L-arginine methyl ester and N-iminoethyl-L-ornithine administration.

Methods: The study included 50 adult male Wistar albino rats (weighing 350 to 400 g). Rats were randomly allocated into four groups.

Although non-muscle invasive bladder cancer (NMIBC) is widely seen in men, most laboratory studies of new intravesical therapies to prevent NMIBC have been conducted on female animals. In addition, ozone (O) has been shown to be a beneficial agent as an intravesical application in the treatment of various disorders. In the current study, we evaluated the immunohistopathological and oxidative-antioxidative effects of intravesical O treatment on n-methyl-n-nitrosourea (MNU)-induced NMIBC.

This study investigated the effects of resveratrol (RES) on doxorubicin (DXR) induced rat bone marrow cell chromosome aberrations. RES, a polyphenolic compound, has attracted considerable attention because of its antioxidant and antimutagenic effects. DXR, a chemotherapeutic agent, is known to cause chromosomal aberrations in healthy cells in cancer patients.

Aim: This study aimed to investigate the effects of VNS in transient middle cerebral artery occlusion and reperfusion (MCAO/R) rat model of ischemia based on behavioral, morphological, and molecular approaches.

Material And Methods: Wistar albino rats were divided into 3 groups: ischemia-reperfusion (I/R), I/R+VNS, and sham (for I/R). Each group was further divided into two subgroups for the assessment of neurological deficits and infarct area, or biochemical parameters related to oxidative stress.

Objectives: Our objective was to examine blood and tissue levels of nitric oxide (NO) and malondialdehyde (MDA), and their correlations with well-known prognostic indicators [total prostate-specific antigen (tPSA), %free/total PSA (%f/t PSA), pathological stage (pT), and Gleason sum] in patients who had radical retropubic prostatectomy (RRP) for localized prostate cancer (PCa) without metastasis.

Patients And Methods: Preoperatively 31 patients' bloods were obtained for determination of NO, MDA, fPSA, tPSA, and %f/tPSA ratios. Tissues were obtained from RRP specimens for determination of NO and MDA.

Objectives: the aim of our study was to evaluate the activity of superoxide dismutase (SOD) and the levels of glutathione (GSH), malondialdehyde (MDA), and nitric oxide (NO) in liver and kidney tissues in a rat model of convulsive seizure induced by single and repeated doses of pentylenetetrazole (PTZ) and sound stimulation with key ringing.

Materials And Methods: male Wistar adult rats (n=48), were used in the experiment. The animals were divided into six groups: (1) Single Seizure Control Group (SS-Control; n=8), (2) Repeated Seizures Control Group (RS-Control; n=8), (3) PTZ induced Single Seizure Group (SS-PTZ Group; n=8), (4) PTZ induced Repeated Seizures Group (RS- PTZ Group; n=8), (5) Key-Ringing Induced Single Seizure Group (SS-KEY Group; n=8), (6) Key-Ringing Induced Repeated Seizures Group (RS-KEY Group; n=8).

This study was designed to examine the effects of erdosteine on bleomycin (BLM)-induced lung fibrosis in rats. Thirty-three Sprague-Dawley rats were divided randomly into three groups, bleomycin alone (BLM), bleomycin + erdosteine (BLM + ERD), and saline alone (control). The BLM and BLM + ERD groups, were given 2.

Objective: Cisplatin (DDP, cis-diamminedichloroplatinium II) is one of the most potent chemotherapeutic antitumor drugs, but is able to generate reactive oxygen species (ROS) and it also inhibits the activity of antioxidant enzymes in renal tissue. In the present study, we investigated the preventive effect of 100, 200 and 400 mg/kg b.w.

Objective: Long-term inhalation of thinners may cause damage, both to the lungs and to other organ systems. It causes cellular damage via formation of reactive oxygen species. The lung is protected from oxidative stress by the glutathione (GSH) antioxidant system which can be augmented by the thiol drug, N-acetylcysteine (NAC).

Background: Excessive generation of reactive oxygen species (ROS) contributes to the process of progressive renal injury in a variety of clinical and experimental renal diseases. The present study was designed to test the hypothesis that treatment with vitamins decreases renal injury in chronic renal failure (CRF).

Methods: Forty male Sprague-Dawley rats were divided into 5 groups: group 1, control; group 2, 5/6 nephrectomy (CRF); other groups 5/6 nephrectomy and injected vitamins (E, A, D).

Purpose: To evaluate plasma total homocysteine (tHcy) and nitric oxide (NO) marker levels in patients with pseudoexfoliation syndrome (PXS), pseudoexfoliation glaucoma (PXG), primary open-angle glaucoma (POAG), and normal controls.

Methods: This cross-sectional, prospective study involved 19 patients with POAG, 18 with PXS, 22 with PXG, and 20 control subjects. Fasting tHcy levels of all study participants were determined using a fluorescence polarization immunoassay method.
