Neuralgia is defined as a condition of a sudden and heavy
attacks of pain that follows the path of a nerve or nerves as a result
of a change in neurological structure or function due to irritation or
damage to the nerves without stimulating pain receptor (nociceptor) cells. the disease affects about 2%–3% of the population.
Antioxidant against neuralgia(42)
1. Copper
Copper, an
essential trace element is essential for the absorption and utilization
of iron and distributed widely in the body and occurs in liver, muscle
and bone. Deficiency of copper can often cause the anemia-like
symptoms. However, ingesting too much of it can lead to generator of
free radicals that can damage DNA
1.1. Antimicrobial and viral
Copper enhances the immune function in fighting against foreign
invasion, such as bacteria and virus, thus reducing the risk of
infection and inflammation by utilizing the absorption of oxygen and
production of energy within cells.
1.2. Antioxidant enzyme Superoxide dismutase (SOD)
Copper
is vital for the making of antioxidant enzyme, superoxide dismutase,
an important antioxidant defense in nearly all cells exposed to oxygen
by protecting the cell membranes from free radicals. In fact, it
outcompetes damaging reactions of superoxide, thus protecting the cell
from superoxide toxicity. Research found in experiment, Mice lacking
SOD1(Superoxide dismutase [Cu-Zn]) develop a wide range of pathologies,
including hepatocellular carcinoma, an acceleration of age-related
muscle mass loss,an earlier incidence of cataracts and a reduced
lifespan. Mice lacking SOD3(Extracellular superoxide dismutase [Cu-Zn] )
do not show any obvious defects and exhibit a normal lifespan, though
they are more sensitive to hyperoxic injury and mice lacking SOD2
(Superoxide dismutase 2, mitochondrial) die before birth. The above
result enhances the importance of the presence of copper in improving
life span and living health in human as well.
2. glutathione (GSH)
Glutathione
(GSH), a polypeptide of glycine, cysteine, and glutamic acid that
occurs widely in plant and animal tissues beside is best known for its
role in enhancing the immune system in protect our body from bacteria
and virus, it also is an antioxidant that helps to prevent damage caused
by oxidation of cellular components such as free radicals and
peroxides by converting to its oxidized form glutathione disulfide
(GSSG), leading to generation of antioxidant enzymes, glutathione
peroxidases and peroxiredoxins of which reduces the risk of oxidative
DNA damage and subsequently the individual’s risk of cancer
susceptibility.Deficiency of Glutathione (GSH) causes hemolytic
anemia, progressive degeneration of the spinal cord, disorders of the
peripheral nervous system, diseases of the skeletal muscles, etc.
Intake with vitamin D increases glutathione levels in the brain and
appears to be a catalyst for glutathione production.
3. Alpha lipoic acid
Alpha
Lipoic Acid (ALA) is an organosulfur compound derived from octanoic
acid. It has been used as over-the-counter nutritional supplements to
treat a number of diseases and conditions. Alpha Lipoic Acid (ALA) not
only is importance in preventing the symptoms of vitamin C and vitamin E
deficiency, but also generates dihydrolipoic acid by reduction of
antioxidant radicals. Recent study showed that Alpha lipoic acid
may have a therapeutic and anti-aging effects due to modulation of
signal transduction and gene transcription, which improve the
antioxidant status of the cell.
4. Manganese
Manganese
is an essential trace nutrient in all forms of life. It is well known
for its role in helping the body to maintain healthy skin and bone
structure, but also acts as cofactors for a number of enzymes in higher
organisms, where they are essential in detoxification of superoxide
(O2−, with one unpaired electron) free radicals. Although
superoxide is biologically quite toxic and is deployed by the immune
system to kill invading microorganisms by utilizing the enzyme NADPH
oxidase. Any Mutations in the gene coding for the NADPH oxidase cause an
immunodeficiency syndrome. Superoxide may contribute to aging
via the oxidative damage that it inflicts on cells. In larger amounts,
manganese can be poisoning to neurological damage which is sometimes
irreversible.
5. Selenium
Selenium
, a trace mineral plays an important and indirect role as an
antioxidant by fulfilling its function as a necessary constituent of
glutathione peroxidase and in production of glutathione, that inhibits
the damage caused by oxidation of free radical hydrogen peroxide,
leading to aging effects.
5.1. Heart health
Since it works
synergism with vitamin E, it promotes heart health. Study showed by
increasing the levels of glutathion, selenium decreases the risk of LDL
oxidation, thus lowering the risk of plaque building up on the arterial
walls, blood pressure and heart diseases.
5.2. Immune system
Selenium
enhances the immune function that fighting off the attack of AID virus
by promoting the function of interleukin 2 and T-cells.
5.3. Cancer
Study showed that levels pf selenium in blood test is associated with high rate of cancer, including skin cancer.
6. Zinc
Zinc
is an essential mineral that is naturally present in some foods. The
ability of zinc ininhibiting oxidative processes has been recognized for
many years. Chronic effects, zinc enhances the introduction of
metallothioneins, which help to capture the superoxide and hydroxyl
radicals due to cysteine residues, resulting in lessening the risk of
oxidative stress.
Over acute effects, zinc may reduce the
postischemic injury to a variety of tissues and organs by involving the
antagonism of copper reactivity as a result from its antioxidant
functions.
