Building Immune System
Building Immune Power: During his research, Dr. H. Sherwood Lawrence has founded “information molecule” of immune system that is contained on while blood cell. That molecule can be moved from other people and will give the recipient a body impenetrability from certain disease. He named that molecule a “Transfer Factor” (TF). On the next research this TF also founded on colostrums (the first mother milk) and on yellow part of egg.
More than 50 years after finding of Transfer factor, scientists from more than 60 countries than work for the next research. More than 3,500 report of scientific report have been launched and more than US $40 million have expensed for that research. Extraction process of that Transfer Factor from the colostrums of cow and the yellow part of egg have been patented by 4 life researcher.
Cancer Institute of Singapore have recorded that 1 in 3 Singaporean are likely to be infected by Cancer during their lifetime, and 1 in 4 Malaysians will suffer from Cancer as National Cancer Registry of Malaysia, Indonesia, no registry.
“Without an Immune System, YOU CANNOT SURVIVE…”
“To the degree your immune system works you are able to adapt to a WORLD FULL OF PATHOGENS and MICROBIAL THREATS.”
For several people an immune system have build naturally from they are birth, such as native Irian Jaya of Indonesia, this people have a natural Immune system to Malaria disease. Even many cases, Irian Malaria make other people die, but the native people will never get a malaria disease.

Blood Clotting
The clotting process is initiated by a protein called tissue factor, which is bound to the membranes of most cells outside the bloodstream. Blood coming into contact with these membranes sets off a sequence of reactions involving various blood protein called factors. Thus, a molecule of factor VII coming into contact with tissue factor converts to an active form that in turn converts ten molecules of factor X into thromboplastin, with the help of calcium ions. Thromboplastin in turn binds to factor Va, which then binds to the protein prothrombin to form two million molecules of the clotting enzyme thrombin. Thrombin acts as a catalyst to convert fibrinogen to billions of molecules of the insoluble protein fibrin, the basis of the final clot. The clot is made firm by factor XIII, reinforced by blood platelets.
Because minor injuries often occur, the clotting process is almost constantly taking place somewhere in the body. It must be terminated quickly, however, or blood would clot everywhere and death would ensue. To prevent this form happening, plasma proteins known as fibrinol-ysins, or plasmin, dissolve old clots in the bloodstream.
Blood Transfusions
Transfusions involve the intravenous administration of blood from a donor to a patient. The procedure's safety and effectiveness relates, in large measure, to careful donor selection and to pre-transfusion testing. Blood is now mainly transfused as components rather than as whole blood; a donated unit is separated into its cellular and plasma constituents and transfused according to the patient's clinical needs. Thus, blood from single donor can provide or the needs of several patients.
There is no true artificial substitute for blood. Some experimental solutions can transport oxygen to the tissues temporarily, and synthetic plasma substitutes are used to raise blood fluid levels.

Blood Diseases
Anemia is a deficiency of hemoglobin in the blood, generally caused by blood loss; abnormal destruction of the red cells, as in Sickle-cell disease; or inadequate red cells formation by the bone marrow, as in a plasmatic anemia and pernicious anemia. Anemia also occurs as a result of methermoglobinemia, a disorder in which methemoglobin, a nonfunctional form of hemoglobin, is present in the red cells.
In some persons, the concentration of red cells and of hemoglobin in the blood may be abnormally increased, rather than decreased, resulting in polycythemia. This is usually caused by an increased production of red cells, but in some persons it may be caused by a decreased volume of plasma.
Neutropenia
Deficiency of circulating granulocytes with poor resistance to infection, may occur in many diseases. One common cause is the use of X rays and toxic drugs to treat many malignant diseases.
Leukemia
A great increase in abnormal leukecytes may occur for unknown reasons, resulting in the diseases known as the leukemias. These range from the chronic lymphocytic leukemia, in which a person may live form many years, to devastating acute leukemia, often causing death within month.
Thrombocytopenia
The number of platelets can severely decrease, with danger of bleeding. Perhaps the most common cause of platelet deficiency, or thrombocytopenia, is an autoimmune disease related to autoimmune hemolytic anemia. The difference is that, in these cases, the body produces antibodies that attack only the platelets.
Hemophilia
Deficiencies of one or more of the plasma coagulation factors may also cause abnormal bleeding. The existence of many of the clothing factors was recognized only when persons were found who lacked such a factor. The best known such bleeding disorder is Hemophilia.
Thromboembolic Diseases
Abnormal clotting in the blood vessels, known as thromboembolic disease, may be caused by an excess of one or more of the plasma clothing factors, or at times to a deficiency of one of the fibrinolytic factors. This group of disorders is one of the most common causes of death in middle aged and elderly persons.

White Blood Cells
There are three types; granulocytes, lymphocytes, and monocytes. Granulocytes, accounting for about 70 percent of all white cells, include neutrophilis, ensinophils, and basophils. They are formed in the bone marrow. Lymphocytes form primarily in the Speen and lymphnodes. Monocytes are believed to originate from lymphocytes.
Platelets
Platelets, or thrombocytes, are tiny bits of cytoplasm, much smaller than the red blood cells but lacking a nucleus. They are round or biconcave disks and are normally about 30 to 40 times more numerous than the white blood cells. They are produced as broken fragments of the megakaryocytes. The plateletss' primary function is in the clotting process described below.
Plasma
Plasma is a complex, colorless solution, about 90 percent water, that carries different ions and molecules, including protein, enzymes, hormones, nutrients, waste materials such as urea, and fibrinogen, the protein that aids in clotting. The most abundant plasma protein is albumin, which normally keeps a large portion of the body water in the blood. When the plasma albumin concentration becomes dangerously low, because of disease, free water collects in the tissues outside the blood vessels, producing swelling called edema.
Globulin are large protein molecules of many chemical structures and functions. The antibodies, produced by lymphocytes, are globulin and are carried throughout the body, where many of them fight bacterial or viral invasion. Other antibodies are related to the blood groups.
An important function of plasma is to transport nutrients to the tissue. Glucose, absorb from the bowels, constitutes a major source of body energy. Some plasma proteins and fats are also used by the tissue for cell growth and energy. Minerals essential to body function, although present only in trace amounts, are important elements of the plasma.

Blood and the Type
Red Blood Cells
Red blood cells, or erythrocytes, are tiny, round, biconcave disks averaging7.5 microns (0.003 in) in diameter. A normal 76.5 kg (170-lb) main has about 5 l (5.3 qt) of blood, containing more than 25 trillion red cells. Because the normal life span of red cells is only about 120 days, more than 200 billion cells are normally destroyed each day by the spleen and must be replaced. Red cells are made in the bone marrow.
The main function of the red blood cells is to transport oxygen from the lungs to the tissue. Oxidations of various food substances to supply most of the energy requirements of the body results in carbon dioxide, one of the chief waste products, and red blood cells carry it to the lungs for release and to pick up more oxygen.
The substance in the red blood cells that is largely responsible for their ability to carry oxygen and carbon dioxide is hemoglobin, the material that gives the cells their red color. Produced in the bone marrow and broken down in the spleen, it is a protein complex comprising many linked amino acids, and occupies almost the entire volume of a red blood cell. Essential to its structure and function is iron.
Blood Typing
The cell wall contains many antigenic proteins, which determine the blood type. Among these proteins are the antigens. A and B, the major blood group factors. Blood with antigen B is group B. Blood with both antigens is called AB, and blood with neither is called group O. Normally, the plasma of every person contains an antibody against the A or B antigens in the red cells are determined by mixing the cells with known typing serums. The antibodies in the serum or plasma are determined by mixing it with cells of known A or B type. Such typing is necessary in preparation for blood transfusion. Antigens of the various Rh and Hr types, M and N, S and Kell, Duffy, and many others also exist in the red blood cell. All like the A and B antigens, are inherited. When the red cell antigens are determined, they show so many different combinations as to make a persons blood type almost as individual as a fingerprint.
Antibodies against antigens other than A and B do not normally occurs in the plasma. They may appear after transfusion, however, and may cause transfusion reactions and destruction of red blood cells or hemolytic disease of the newborn.
