Noise is defined as a displeasing and unwanted sound. It is one of the most encountered stressor to which mankind is exposed. Frustration, poor reading, impaired hearing and difficulty in problem solving activities are the common consequences of noise stress. It has been reported to produce atrophy of dendrites and alterations in neurotransmitter levels.(More)
Mankind is exposed to a number of stressors, and among them noise is one which can cause intense stress. High levels of background noise can severely impair one's ability to concentrate. The present study was aimed to investigate the effect of sub-chronic noise stress on cognitive behavior and hippocampal monoamine levels in male rats. The study was(More)
Oxidative stress from generation of increased reactive oxygen species or free radicals of oxygen has been reported to play an important role in the aging. To investigate the relationship between the oxidative stress and memory decline during aging, we have determined the level of lipid peroxidation, activities of antioxidant enzymes, and activity of(More)
Cadmium is a toxic environmental and industrial pollutant. Cadmium toxicity has been reported to produce biochemical and behavioral dysfunction that may cause adverse effects on several organs including the central nervous system. The present study was designed to investigate the neurotoxic effects of Cadmium Chloride (CdCl2) at three different doses by(More)
Lead toxicity is known to induce a broad range of physiological, biochemical and behavioral dysfunctions that may result in adverse effects on several organs, including the central nervous system. Long-term exposure to low levels of lead (Pb2+) has been shown to produce behavioral deficits in rodents and humans by affecting hypothalamic-pituitary-adrenal(More)

Dietary nutrients may play a vital role in protecting the brain from age-related memory dysfunction and neurodegenerative diseases. Tree nuts including almonds have shown potential to combat age-associated brain dysfunction. These nuts are an important source of essential nutrients, such as tocopherol, folate, mono- and poly-unsaturated fatty acids, and(More)
Magnesium (Mg) is the fourth most abundant biological mineral essential for good health. Neuroprotective, anxiolytic and antidepressant effects of magnesium following stress and brain injuries are well established. In present study, we analyzed the protective effects of magnesium in rats exposed to sub-chronic noise stress. Magnesium Chloride (MgCl2, 100(More)
It is observed that memories are more strengthened in a stressful condition. Studies have also demonstrated an association between stressful events and the onset of depression and anxiety. Considering the nootropic, anxiolytic and antidepressant-like properties of curcumin in various experimental approaches, we appraised the beneficial effects of this herb(More)
The present study was designed to investigate the gastroprotective, analgesic, and antipyretic effects of curcumin (Cur), the major constituent of turmeric. Acetylsalicylic acid (ASA) was used in this study as a standard drug for comparison. The analgesic activity was measured using the Hot-Plate Test. The antipyretic and antiulcer effects were assessed(More)
