The effects of acute exposure to cadmium (Cd) on the blood antioxidant defense system, lipid peroxide concentration and hematological parameters, as well as the possible protective role of vitamin E were studied. Male Wistar albino rats (3 months old) were treated with cadmium (0.4 mg Cd/kg b.m., i.p., 24 h before the experiment) or with vitamin E + Cd (20 IU Vit E/kg b.m., i.m., 48 h + 0.4 mg ...

The rhizomes of Nardostachysjatamansi, the plant commonly known as Jatamansi have been described in Ayurveda for their soothing and sedative action on the central nervous system. In the present study, the anti-stress effect of hydroethanolic extract (70%) of N. jatamansi (NJE) was evaluated in reference to its antioxidant property. Wistar rats were divided into four groups: naive, stressed, and...

The response of enzymatic (superoxide dismutase, SOD; catalase, CAT; glutathione peroxidase, GPX and glutathione reductase, GR) and non-enzymatic responses (glutathione, GSH, oxidized glutathione, GSSG and GSH/GSSG) against acute Cu toxicity (2-90μg/mL for 48h) in different tissues of Lymnaea stagnalis were measured. Incubation conditions for enzymatic activity measurements were optimized for L...

Six hundred 1-d-old male broilers (Ross 308) were assigned to four experimental groups; each was composed of 5 floor pen replications of 30 birds including control (no enalapril), 15, 30 and 60 ppm enalapril in the drinking water. From d 21 to 49, all the chicks were exposed to low ambient temperature to induce ascites. Mortalities were inspected to determine the cause of death and diagnose of ...

Background and aim: Extraction of natural antioxidant compounds has recently attracted the attention of researchers. Almond is one of the native products of  Iran, which annually during the process of production , large volumes of waste is achieved. The aim of this study is investigating the impact of two parameters (time and ethanol percentage) on the extraction of phenol and ...

male infertility evaluation is important to recognize an origin and provide treatment if the etiology is correctable. the aim of the present study was to investigate the protective role of lavandula angustifolia in impaired spermatogenesis caused by cadmium chloride in male rats. 36 male wistar rats were allocated in 6 groups. cadmium chloride was injected for 3 consecutive days (0.5 mg/kg) in ...

The aim of this work was to determine the effect of dietary n - 3 PUFA on oxidant/antioxidant status, in vitro very low and low density lipoprotein (VLDL-LDL), and VLDL-LDL-fatty acid composition in macrosomic pups of diabetic mothers. We hypothesized that n - 3 PUFA would improve oxidative stress in macrosomia. Diabetes was induced in female Wistar rats fed with the ISIO diet (control) or with...

OBJECTIVES: To study the effect of supplementation with an association of small physiological amounts of antioxidant nutrients upon biochemical parameters and indicators of oxidative stress and antioxidant enzymes. DESIGN: The study included a double-blind placebo-controlled design. SUBJECTS: 575 elderly long term hospitalized subjects aged 65-103 years. INTERVENTION: Four groups were compared....

Human semen contains spermatozoa as well as populations of round nonspermatozoal cells primarily consisting of leukocytes. Activation of white blood cells present in the seminal plasma during genital tract inflammation and cellular reactions against microbial agents may provoke a release of a variety of products such as cytokines and reactive oxygen species. The aim of this study was to evaluat...

Th e aim of this study was to determine the chemical composition and antioxidants capacity of three plum cultivars, namely ‘Top’, ‘Elena’ and ‘Bistrica’. Fruits were harvested and following parameters were determined: dry matter, total acids (TA), total soluble solids (TSS), pH, vitamin C, total phenols, nonfl avonoids and antioxidant capacity. Diff erences between cultivars for most of the che...
