Lindane Case Study
Curcumin amends oxidative stress and antioxidants status in olfactory lobes, cerebrum, hypothalamus-hippocampus, cerebellum and pons-medulla of mice acutely intoxicated with lindane
Abstract: Present study ascertains the neuroprotective potential of curcumin in olfactory lobes, cerebrum, hypothalamus-hippocampus, cerebellum and pons-medulla of mice, intoxicated with lindane. Lindane is highly toxic to central nervous system (CNS), causing mental and motor retardation. Oxidative stress due to abnormal production of reactive oxygen species (ROS) and impairment of endogenous antioxidants is believed to be involved in the toxicity induced by lindane. Curcumin has antioxidant property to mitigate the toxicity induced by lindane. For the study mice

Group I was control and it received olive oil as a vehicle. Lindane (25 mg/kg b.w) and curcumin (45 mg/kg b.w) were administered to the mice of group II and group III. Group IV was treated with the curcumin and lindane both. Curcumin was injected 10-15 minutes prior to exposure of lindane in group IV. Mode of exposure of lindane and curcumin was intraperitoneal .
After 12 hours of exposure, mice were cervical dislocated and olfactory lobes, cerebrum, hypothalamus-hippocampus, cerebellum and pons-medulla regions of brain were immediately removed. After the collection, all the brain regions were washed in normal saline.
Tissue homogenate preparation: 10% homogenates of different parts of brain in phosphate buffer (0.1 M, pH 7.4) were prepared. Tissue homogenates were stored at -200 C and used for determination of various biochemical paramaters. For affirmation of toxicity in different brain regions due to lindane, a change in oxidative stress and endogenous antioxidants was used as biomarker.
Oxidative stress: TBARS level and protein carbonyl content (PCC) were used as biomarkers of oxidative stress. TBARS level was measured by the method of Ohkawa et al (1961) whereas Levine et al (1990) method was used for determination of PCC

    In order to conduct this study, male Sprague Dawley rats at sixteen months old were used. They were put into normal living conditions with access to plenty of food and water. The rats were then divided into four different groups. According to Zhang, Zheng, Dong, and Wang (2012), “group A was sham operated control animals, group B was focal cerebral ischemia model, group C was vascular dementia model, and group D was vascular dementia model treated with nimodipine.” The rats were then taken into surgery and were “induced using the bilateral middle cerebral artery occlusion-reperfusion method (Zhang, Zheng, Dong, and Wang, 2012).” In this study, the body temperature was to be kept the same. They used a point system to determine what kind of cognitive deficit the rats had. If the score was greater than three, the rats were then selected for inclusion for groups D and C. All other rats in the other groups were given a saline solution on the same schedule. After all appropriate testing, ten rats were deemed excluded from the study, which left fifteen rats in each experimental group. According to Zhang, Zheng, Dong, and Wang (2012), the Morris Water Maze Test was performed after placing the rats into two different subgroups. One group was for the rats that were trained after two months and the other for those that were trained with the test for four months. This test consisted of the rats being…

    The topic of this paper is estrogen’s neuroprotective mechanism in reference to neuronal injury and repair and the actual method of neuroprotection estrogens utilize. Estrogens play a monumental role in protection from brain injury and neurodegenerative disease (Lebesgue, 2009). Research questions dealt with estrogen’s specific mechanism for neuroprotection and whether or not estrogen’s neuroprotection changed over a life time. Research on estrogen’s neuroprotective mechanisms is emerging and growing every year. This paper will discuss two papers with varying results on how estrogen protects neurons and other nervous tissue. Methods of the literature to be reviewed are animal testing and statistics. The animals were tested for a base line, placed under various forms of neuronal injury in the presence of estrogens, and tested again. The animals who had a higher concentration of estrogen recovered and performed better than the animals with less estrogens. Estrogen’s neuroprotection is not yet well understood, but science is recognizing its immense aid in protecting neurons from extensive damage.…

    Evidences have shown that Bcl-2 protects neural cells from glutamatergic insults, which are thought to lead to cell death, neuropil reshaping, and subsequent abnormalities in brain volume. It has been reported that Bcl-2 expression could be an important factor promoting neuronal survival after increased exposure to Glu. An increase in Bcl-2 expression has been also reported to protect cells against the deleterious effect of Glu toxicity…

    As recorded in the U.S federal government’s patent on this plant, cannabis or marijuana is an anti-oxidant and a neuroprotectant. This is significant for ALS disease as the neuroprotectant and anti-oxidant properties of cannabis can help in slowing down the progress of the disease. It protects the motor neurons that the disease attacks and kills (as mentioned in Gregory T. Carter 201). The anti-oxidant properties of cannabis also help in reducing the oxidative stress at a cellular level that leads to…

    The brain has a specialized vasculature that extends from the surface to deep within the brain tissue, reaching all regions in order to meet the brain’s high metabolic demands. Exposures to toxic compounds entering the blood have the potential to access this vasculature leaving the brain susceptible to possible neurotoxicity. Currently, there are over 200 known chemicals that have been correlated with neurotoxicity. A protective mechanism called the blood brain barrier (BBB) was first discovered in 1880 by researcher Paul Elrich, which demonstrated that IV administration of certain dyes stained all organs but spared the brain and spinal cord.…

    Chronic Arsenic Exposure

    • 331 Words
    • 2 Pages

    Subchronic level of arsenic exposure can affect the level of monoamine neurotransmitters in mice brains. Arsenic can downregulate the concentrations of norepinephrine (NE), dopamine (DA), monoamine oxidase (MAO) and 5-OH tryptamine (5-HT) in the cerebrum or cerebellum of mice. Arsenic increases acetylcholinesterase in brain tissue [7, 8]. The oxidative damage results in structural deformities in the myelin sheath of nerve fibers and degradation in the terminals of the mossy-fibers impairing synaptic function and spatial memory [9]. Mechanistically, an elevated export of GSH and accelerated consumption of cellular glucose resulted in lactate production [10]. In addition, arsenic-treated astrocytes revealed a higher toxic potential of arsenite compared to arsenate, accompanied with a loss of total cellular glutathione with an increase in the cellular glutathione disulfide content…

    There are three types of painful, deadly experiments that are performed on animals. The first is the Draize eye test. This test is mostly performed on rabbits to check for irritancy of shampoo, weed killers, pesticides, and detergents. The product is left in the animal’s eye for up to 14 days for observation, and it almost always results in blindness. The second test is the lethal dosage test. This test is used for testing of cosmetic products including lipstick, face wash, and nail polish. The procedure is performed in order to test the toxicity or irritancy of products in an attempt to determine how much of a chemical or substance it takes to kill an animal within a set time. The third test is used to determine skin toxicity. In this test, the animal is shaved and the toxic substance is absorbed into their skin. The animal is then analyzed for certain responses and reactions which are often unreliable. During the test, the animals are restrained so that they cannot lick their wounds for relief, and if the…
