Antioxidants are the chemical substances that are capable of binding to the free oxygen radicals and averting the destruction of the healthy cells by these or antioxidants are the substances which inhibits oxidation. Antioxidants are predominantly important in perspective of biology and organic chemistry as all existing cells enclose intricate systems of the antioxidant chemicals or enzymes to avoid chemical harm to the cellular components through oxidation.
All Living organisms do have a composite scheme of chemicals and antioxidant enzymes some of which are conserved throughout the evolution and thus are necessary for life. Antioxidants have immense significance in the biological systems, including defending oxidative injure and contributing in major signaling passageways of the body cells.
The most important function of antioxidants in the body cells is to avert harm by action of the imprudent oxygen species like superoxide anion (O2), hydrogen peroxide (H2O2), and free radicals including hydroxyl radical (• OH). Such molecules are unsteady and extremely reactive, and capable of spoiling cells by chemical sequential reactions for example lipid peroxidation and DNA adducts formation that might lead to cancer-promoting alteration or death of the cell. All cells thus possess antioxidants serve to lessen or avoid its damage.
Antioxidants are further categorized as inert and pro- oxidant on the type of the product released at the end of the oxidation reaction in the cells. Antioxidants are principally imperative in the eukaryotic cells mitochondria as oxygen utilization during the process of generating energy generate imprudent oxygen species. The aerobic metabolism process requires oxygen as oxygen provides the final quiescent place for generated electrons by oxidation steps in citric acid cycle.
Antioxidants dietary supplements are essential to slow down, avoid, or even overturn certain illnesses that are due to certain cellular damage, and conceivably even dawdling down the normal aging process. Some of the important antioxidant dietary supplements are provitamin A (beta carotene) vitamin E, vitamin C and Selenium, or some special herbs known to have antioxidants values like those of jiaogulan and green tea.
Studies have recommended that antioxidants are significantly useful in several ways concerning the management of cancer. Antioxidants improve the efficiency of chemotherapy; reduce side effects of radiotherapy and chemotherapy and preventing some kinds of cancer. Adequate epidemiological revisions have revealed that ingesting antioxidants containing like vegetables and fruits, can reduce the jeopardy of numerous forms of cancer and it is observed in several studies that blood of cancer patients contain reduced level of antioxidants.
Antioxidant dietary supplement are those food supplements containing antioxidants obtainable from plants. Though antioxidants play a vital role in our bodily defense mechanism they are to be supplied from outside either as food or other ways. Investigations and studies on biological sciences reveal that consumption of antioxidant dietary supplements reduces harm to cells and biochemical in the free radicals.

Understanding Leukemia is Need for All
By: Nandeshori Devi Konthoujam | 07/08/2006 | HealthLeukemia is any of the sharp or persistent neoplastic ailments of bone marrow wherein unrestrained propagation of leukocytes or white blood corpuscles occurs, generally in association with anemia that is damaged blood clotting, and magnification of the liver, lymph nodes, and spleen. Leukemia is observed in animals including as cats, cattle, guinea pigs, over and above in humans. There is no age difference in leukemia disease that is both children as well adults may suffer from this fatal disease. The central organ of infection in the body is the bone marrow and it spreads to rest of the body with the progress of the disease. Leukemia in other words is a form of cancer where the white blood cells becomes abnormal or huge abnormal cells are being produced by the bone marrow leading to various symptoms ultimately death. Thus leukemia can be considered as a fatal cancerous disease specially those chronic ones. Understanding the characteristics of the normal leukocytes is of great importance to know leukemia. The leucocytes produced in the bone marrow fight against the diseases and infections. Leukemia may be influenced by genetic as well as environmental factors. The genetic factors of Leukemia are somatic alteration in DNA which triggers oncogenes or degenerate cancer suppressor genes disrupting the regulation of cell differentiation, death, or division. These somatic mutations in DNA may happen spontaneously or due to exposure to carcinogenic substances or radiation and are probably influenced by the genetic factors. Revelation to petrochemicals including benzene, hair dyes, certain Viruses like HIV, conscientious for AIDS or human T-lymphotropic virus and adult T-cell leukemia or lymphoma as well as Fanconi anemia are some other causal factors of leukemia. Leukemia is categorized into myeloid or lymphocytic depending upon the kind of affected leukocyte. Leukemia is also categorized as acute, referring to those rapidly succeeding disease which involves immature leukocytes and chronic with a slower proliferation concerning mature white blood cells. In acute leukemia, juvenile nonfunctioning leukocytes known as blast cells propagate. The myeloid leukemia distressing the granulocytes growing myelocytes is further divisible into acute and chronic myeloid leukemia. The lymphocytic leukemia also known as T cell or B cell leukemia affecting the lymphocytes growing white blood cells including acute and chronic cases. Leukemia symptoms are usually the symptoms when the blood synthesizing bone cell in infected and the leukocyte level in the blood increase at an excessive range. The associated leukemia symptoms are also occurring unknowingly with high speed in progress. Leukemia symptoms includes infection, fever, extreme bruising, fatigue, physical exercise prejudice, abdominal soreness, or usually sensitivity of fullness, weight reduction, unusual bleeding, amplification of spleen, lymph nodes, and liver and overall weakness etc. People suffering from leukemia frequently have fewer red blood cells and platelets than normal quantity. As an effect, there are not sufficient erythrocyte cells for carrying oxygen throughout the body and the condition leads to anemia. The leukemia symptoms are depending on amount of anomalous cells and resulting to a large number of leukemia symptoms in the patient. The track of treatment for leukemia is based on the kind of the cell affected, the sequence of disease, as well as age of the enduring patient and can be confirmed by pronouncing a inconsistent count of leukocytes or white blood cells in tissues through a bone marrow biopsy test. Radiation therapy, chemotherapy by anticancer drugs, blood as well as plasma transfusions, and transplantation of bone marrow are the recent and most excellent treatments for leukemia. Latest studies have specify that blood from placenta (cord blood) and umbilical cord of a newborn baby are used effectively as an alternative to marrow transplantation for some leukemia. Biological therapies comprising interferons; monoclonal antibodies; maturation drugs, including tyrosine kinase inhibitors and all-trans retinoic acid may enhance the natural reaction of body to leukemia by strengthening the immune retort, inhibiting the gene which drives cell propagation, or may persuade maturation of undeveloped leukemic cells or reproduction of desirable healthy blood essentials.
