Assay Guided Comparison for Enzymatic and Non-Enzymatic Antioxidant Activities with Special R...

The antioxidant properties oí Acantholippia deserticola, a herb used in traditional northern Chilean medicine was studied using free radical-generating systems. The 50% aqueous-ethanol extract oí Acantholippia deserticola protected against non-enzymatic lipid peroxidation in microsomal membranes of rat, induced by an Fe++-ascorbate system and measured spectrophotometrically by the TBARS test, a...

background: in patients with non-obstructive azoospermia (noa), vital spermatozoa from the tissue is obtained from testes by enzymatic treatment besides the mechanical treatment. objective: to increase the sperm recovery success of testicular sperm extraction (tese), with enzymatic digestion if no sperm is obtained from testis tissue by mechanical method. materials and methods: tissue samples w...

βThalassemia is an inherited genetic disorder which is caused by different kinds of mutations in the HBB gene in chromosome 11. Due to several types of mutation in βgene, globin chains cannot synthesise completely and free α-globin is highly unstable and readily precipitates bound heme and iron. In βthalassemia these precipitated iron, repeated blood transfusion and increased gastrointestinal i...

BACKGROUND AND OBJECTIVES The diet is a key environmental factor implicated in health and disease. Oxidative stress, antioxidant status and their relation to diet is a subject of interest in recent years. The objective of the study was to compare lipid peroxidation and antioxidant status in healthy vegetarians and non-vegetarians. METHODS The present study comprises 100 healthy individuals (5...

Earthworms have been widely used in traditional medicine for thousands of years. However, it is only during the past few decades, with the development of biochemical technologies, that research on the pharmaceutical effects has been initiated. The present study was carried out to investigate the hepatoprotective and antioxidant properties of indigenous earthworm powder (Perionyx excavatus), usi...

Methanol is primarily metabolized by oxidation to formaldehyde and then to formate. These processes are accompanied by formation of superoxide anion and hydrogen peroxide. This paper reports data on the effect of methanol on antioxidant status and lipid peroxidation in lymphoid organs such as the spleen, thymus, lymph nodes and bone marrow of rats. Male Wistar albino rats were intoxicated with ...

Mucuna pruriens Linn., a leguminous plant, has been recognized as an aphrodisiac and spermatogenic agent. Protective efficacy of M. pruriens on reactive oxygen species (ROS)-induced pathophysiological alterations in structural and functional integrity of epididymal sperm in aged Wister albino rat was analysed. Animals were grouped as groups I, II, III and IV, i.e. young (control), aged, aged tr...

Patients with diabetes mellitus are likely to develop certain complication such as retinopathy, nephropathy and neuropathy as a result of oxidative stress and overwhelming free radicals. Treatment of diabetic patients with antioxidant may be of advantage in attenuating these complications. Oleuropein, the active constituent of olive leaf (Olea europaea), has been endowed with many beneficial an...

The present study evaluated the in vitro anticataract and antioxidant activities of ethanolic seed extract of Abrus precatorius Linn. (Fabaceae) against calcium-induced cataractogenesis using goat lenses. Transparent isolated goat lenes were incubated in artificial aqueous humor and divided into seven experimental groups. The extracts at a dose of 100 μg/ml and 200 μg/ml were incubated simultan...
