The mediators released by mast cells and basophils can be grouped into two categories:
(1) preformed substances contained within granules and
(2) newly generated chemicals synthesized following cellular activation.
These mediators comprise the effector function of the mast cell. Together they are able to increase vascular permeability, dilate vessels, cause bronchospasm, contract smooth muscle, and summon inflammatory cells. Few cells in the body produce compounds with such a large and varied spectrum of activity. (more…)
By definition, allergy is a condition where a person has hypersensitivity to an environmental, drug, or food antigen (allergen) caused by an altered or unusual immune system reaction to the antigen.
Allergenic foods can impact the lungs when an allergic reaction individual inhales food particles that may have been released when the food was cooked or that were dispersed in aerosol form. Allergy to the allergens in cooked food has been reported by highly allergic patients who were exposed to their allergenic foods (say, fish, shellfish, or eggs) in an enclosed area (for example, a restaurant dining room) or during meal preparation. Most cases of asthma triggered by aerosolized food allergens involve adults engaged in specific occupations that regularly expose them to the allergens. In contrast, most cases of asthma in children are triggered when the allergen is eaten, not inhaled.
Many experts believe that if a baby can be protected from becoming sensitized to the most highly allergenic foods when their healthy immune system and the digestive tract are in the most vulnerable stage for allergy to develop, the incidence of lifelong food allergy and potentially life-threatening anaphylactic reactions to foods will be reduced and hopefully entirely prevented. When a baby has been identified to be at risk for developing allergy, measures to reduce allergic sensitization might be implemented at birth and the problems associated with future food allergy may be significantly reduced. However, as we shall see in later discussions, experts disagree on the best way to avoid this early allergic sensitization.
The reaction of asthmatics to these chemical compounds is not an allergy, but is more correctly described as allergy intolerance because the initial response is not a triggering of the immune system. The process involves an increase in the level of the inflammatory mediators that are responsible for the bronchospasm of asthma. These mediators include histamine and leukotrienes. They are released during the reaction to an allergen, and cause the muscular contractions that result in the difficulty in breathing and wheezing that are typical of asthma. By inhibiting (or turning off) other types of mediators, the chemicals in the food additives cause an increase in the level of antihistamine and leukotrienes. This results in increased bronchospasm, and a definite worsening of the asthma symptoms.
Oral allergy syndrome is an allergic reaction to food that is confined to the oral cavity (i.e., to the lips, and around the lips, roof of the mouth, tongue, hard and soft palate, and uvula) and adjacent structures. It differs from other food allergy in that its symptoms do not appear in any other location in the body, and always accompany respiratory allergy to inhaled allergens of plants, particularly plant pollens. Of course, symptoms in the mouth, throat, and upper respiratory tract can be part of a generalized reaction to foods, but in this case they are more accurately described as oral allergy symptoms. The term oral allergy syndrome applies specifically to pollen allergy (pollinosis) accompanied by reactions to certain raw foods when they are in direct contact with oral tissues. Individuals with Oral allergy syndrome typically have hay fever symptoms caused by allergies to trees, grasses, and weeds. They experience irritation in the mouth (lips, tongue, roof of the mouth) and sometimes the throat after eating specific types of raw fruits, vegetables, and sometimes nuts.
Almost any kind of conditions sure enough get benefit from BICOM Bioresonance therapy. Bioresonance Treatment is non-invasive, painless and reliable treatment that suitable at any age. Dr. Peter Schumacher BICOM (Pediatrician) was popular in 1991 to effectively counterbalance the allergic reaction in children. In China, BICOM almost exclusively in children’s hospitals to treat baby eczema and to control asthma. (more…)
There are still many people that are giving consultation to others, suggest the wrong advice in the context of the treatment of baby eczema. Please take note that many of this well-intentioned advice may be more confusion rather than give help to parents. But from time to time, we need to know what you should do when treating baby eczema.

Having a food intolerance test is becoming increasingly popular nowadays. This is because the symptoms of indigestion, stomach cramps, headaches, insomnia and constipation are associated with food intolerance. Food intolerance or food sensitivity is much more common than food allergies. It is estimated that around 10% of people are allergic to a food, but the number is increasing between 30-60% of people with intolerance to one or more additives or chemicals allergies in food.

Extrinsic allergic alveolitis (synonym: hypersensitivity pneumonitis) describes an interstitial and bronchioloalveolar disease of the lungs caused by an immune mediated hypersensitivity response. It is associated with repeated exposure to a variety of inhaled organic dusts and reactive chemicals (allergy chemical), but only a proportion of exposed subjects become affected. Notable examples are farmers’ lung (due to actinomycetes contaminating farm produce) and bird fanciers’ lung (due to secreted avian antigens). The disease has considerable potential as a model of allergic lung disease, since the populations at risk can often be identified precisely, the relevant antigens can be purified, and the clinical and immunologic consequences of antigen exposure can be examined.

Allergies can be defined as inappropriate immune system reactions to a foreign substance entering body. Allergies are kind of diseases of immune system works to react to certain substances called allergens. Normally when a person is exposed to a harmless substance such as pollen, causes the body natural immune system to respond as if the substance is harmful. Some allergies are inherited from their parents or can be gained in environmental exposure. There are several common allergen exposures like mold, animal dander, pollen, dust mites, and many others.

It is widely knowt that pollen, pollution, smoke can trigger an asthma attack. But one interesting thing is exercise can also trigger asthma reactions.
Yes, because normally we breathe through the nose, where air is filtered, warmed and moistened. But when we exercise, especially if we are colds, sinusitis or allergic rhinitis have “breathe through the mouth and the air gets colder and drier the lungs and also unfiltered, so it can carry more allergens (more…)
Gastrointestinal allergy can be classified according to the triggering antigen, the mechanism of immune reaction, or the anatomic site of reaction.
Gastrointestinal allergy may be triggered by food components (e.g. food proteins or glycoproteins), and by other antigen antibody reaction to (e.g. bacterial disease, viral, fungal, and worm antigen), drugs and chemicals, (more…)
Food is essential for sustaining human life. Many love to eat and find enjoyment in this activity. But there are literally thousands people who have “food sensitivities” and suffer adverse allergy effects if they eat particular food that can trigger this event. (more…)
