Learning About the Immune System

The Lymphatic System
The onset of almost all infectious and degenerative disease is preceded or accompanied by inadequate immune response. AIDS epidemic from to Iron and folic acid: When this happens excess lymph accumulates and results in the swelling that is characteristic of lymphedema. A low total IgE level is not adequate to rule out sensitization to commonly inhaled allergens. Stevens GA et al.

Immune system disorder

This is called antigenic variation. An example is HIV, which mutates rapidly, so the proteins on its viral envelope that are essential for entry into its host target cell are constantly changing. These frequent changes in antigens may explain the failures of vaccines directed at this virus. In HIV, the envelope that covers the virion is formed from the outermost membrane of the host cell; such "self-cloaked" viruses make it difficult for the immune system to identify them as "non-self" structures.

Immune deficiencies Immune deficiency disorders result from defects that occur in immune mechanisms. Hereditary and congenital deficiencies Immune deficiencies resulting from hereditary and congenital defects are rare, but they can affect all major aspects of the immune system.

Deficiencies caused by infection Damage to lymphocytes that is inflicted by viruses is common but usually transient. Deficiencies caused by drug therapy In countries with advanced medical services, immune deficiency often results from the use of powerful drugs to treat cancers. Page 1 of 9.

Keep Exploring Britannica Cancer. Finnish researchers came to a similar conclusion. They found that children who eventually developed allergies ate less butter and more margarine compared with children who did not develop allergies.

Of course, health authorities have been urging us for decades to consume more polyunsaturated fats and less saturated fat thereby increasing the severity of asthma. A study in the British Medical Journal September 25, ; , shows that giving babies other milk than breast milk before the age of four months greatly increases the risk of asthma and allergies. This article reports that children who use chlorinated swimming pools every week get lung damage just like smokers. Also lifeguards who work in indoor pools have an increased incidence of asthma.

A surprising Japanese study found that school children who ate more fish had also higher rates of asthma Preventive Medicine February ; As we know from other studies that fish oil and even consumption of oily fish reduce inflammations and asthma, the conclusion is that in this case the high rates of mercury in Japanese coastal waters are the cause of such fish causing increased asthma.

There are also various reports of vaccinations causing asthma. One such case is described under the title: Acta Med Scand Suppl. Finish researchers found that mothers can prevent eczema and asthma in their children by taking Probiotics acidophilus-bifido bacteria while they are pregnant and breastfeeding. Babies normally get their mother's bacteria as they travel down the birth canal, but modern medicine is preventing this. Babies born by caesarian section are inoculated with hospital bacteria such as Streptococci and Clostridia.

In an article entitled "The Dark Side of Immunizations? Science News reports that a study by researchers at the Wellington School of Medicine in New Zealand found that unvaccinated New Zealand children report fewer cases of asthma than vaccinated children. Another study by New Zealand researchers published in the November Epidemiology analyzed the health of 1, people born in Of these, 23 didn't get any childhood vaccinations and none of them suffered childhood asthma.

Among the 1, who got polio and DPT shots, more than 23 percent later had episodes of asthma. Science News adds that a survey of British children, most of them eight years old, showed that 91 received no vaccinations in early childhood. Only one child out of 91 got asthma.

About 11 percent of the other children who had been vaccinated with pertussis and other vaccines had asthma.

Several asthma and allergy researchers have found results similar to the earlier described relationship between immunization and IDDM. Julian Hopkin presented data at the British Thoracic Society meeting in which linked asthma to immunization. Similar results have been suggested by others Odent, Culpin and Kimmel, The culprit behind asthma and allergies: Can vaccines cause immune dysfunction resulting in allergies, asthma and anaphylaxis?

The Institute of Medicine's Immunization Safety Review Committee held a public meeting in Seattle, Washington on November 12, to review the "Possible association between multiple immunizations in newborns and infants and immune system dysfunction. Some, but not all, of these studies suggested that certain vaccines increase the risk of developing allergic disorders.

Methodological weaknesses and inconsistent findings among the studies, however, led the committee to conclude that there is inadequate evidence to either accept or reject a causal relationship between multiple immunizations and increased risk of allergic diseases, particularly asthma. Why the "surge" in anaphylactic children entering school a decade ago?

These children were among the first to receive an additional vaccination, Hib meningitis. Is it possible that the Pertussis and Hib vaccine, both shown below to cause allergic responses, are creating a hypersensitive immune system in some children? Has any study looked into what happens to atopy incidence and IgE levels when 5 vaccines are given concurrently in infants?

Possible association between multiple immunizations in newborns and infants and immune system dysfunction. The exact numbers of children affected by anaphylaxis are difficult to pinpoint. A study in Arch Intern Med Jan 8; 1: On the basis of our figures, the problem of anaphylaxis may, in fact, affect 1.

Pediatr Res Sep;22 3: Mortality observed after bovine albumin challenge is due to an anaphylactic reaction Increasing glutathione levels in the lungs may be beneficial in lung disease. Although there are few studies using glutathione GSH enhancement therapies or nebulized aerosolized and inhaled glutathione in lung diseases, there is good data mostly in animal models suggesting increasing the potent antioxidant and free-radical scavenger glutathione would be beneficial in certain degenerative lung conditions associated with increased free radical load including asthma , cystic fibrosis, bronchiectasis and bronchiolitis obliterans.

Homeopaths have a long history of successful allergy treatment, and they have made some important contributions to present understanding of allergies. Sir William Osler, considered the Father of Modern Medicine, was known to say, "Asthmatics don't die, they just 'pant into old age.

Research conducted by professors at the University of Glasgow, Europe's largest medical school, indicates that those patients given an exceedingly small homeopathic doses of whatever substance to which they are most allergic can provide significant relief within the first week of treatment.

The authors called this unique method of individualizing medicines "homeopathic immunotherapy. The patients were assessed by a homeopathic physician and a conventional physician. When the patients and doctors were asked if they felt the patient received the homeopathic medicine or the placebo, both the patients and the doctors tended to guess correctly.

How Can Homeopathy Help Asthma? Like with Traditional Chinese Medicine, each individual is analyzed for their specific symptoms and an appropriate therapy is chosen, not for the disease, but for the person displaying signs of health out of balance. This is a very important distinction, and, very generally speaking, one of the main differences between conventional and "complementary" approaches to health care.

Please refer to the essay on Homeopathy in the Introduction to Modalities section. American Association of Naturopathic Physicians. They work similar in action to a vaccine- in that a small amount of a substance stimulates the healing mechanisms of the immune system. The beauty of homeopathic treatment is that there are no worries about toxic side effects, relatively inexpensive, and works to repair the immune system and other imbalances in the body.

Recent clinical studies have confirmed the effectiveness of homeopathic medicine in the treatment of asthma. Solid research have proven the effectiveness of homeopathic medicines in hayfever. David Taylor-Reilly, a professor and homeopath at the University of Glasgow in Scotland, published an important study in the Lancet October 18, which showed that homeopathically prepared doses of 12 common flowers were very effective in reducing hayfever symptoms when compared with patients given a placebo.
