Inflammation Mediators and Vascular Responses to Injury or Infection

inflmmation responses
Some of the immediate sequelae of injury are uncomfortably familiar: Soon after an injury occurs, the affected site and its surrounding tissues become reddened, warm, swollen, and painful. These four signs which are probably the most useful and ubiquitous diagnostic clues in all of clinical medicine are hallmarks of acute inflammation, the body’s initial physiologic reaction to tissue distress. In its simplest form, inflammation is a response carried out by blood vessels and by the endothelial cells that line them. (more…)

Mediators of Allergic Response: Lipid Derivatives And Cytokines

Mediators Allergic Response
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…)

Allergen Vaccine and Allergenic Source of Material

Allergen Vaccine
Being an immunological disease, the characteristics of allergy are those of specificity and memory. Regardless of whether the clinical manifestation is rhinoconjunctivitis, rhinitis, or asthma, the underlying immunological response disorder is based on the adverse reactions of cells in the immune system upon contact with allergens. These cells are specific for epitopes that are structural parts of allergens present in the allergenic source material. Two types of cells (i.e., T cells and B-cells) produce receptor molecules (i.e., T-cell receptors and immunoglobulin [IgE] antibodies) that, through high-affinity interactions with the allergen, efficiently catalyze the presence of even minute amounts of allergens into clinical symptoms, the extreme consequence of which may be life-threatening to the patient.

Allergy and Immune System: Living with Allergies & Immune Disorders

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.

Use Natural Hives Remedies for Quick Relief

natural hives remedies

When it comes to relation to natural hives remedies for quick relief, you must first understand what causes the hives, and when it occurs. The Hives are caused when the chemical histamine is released into your body when you get contact with something you allergic with (allergen).

The hives normally indicated by a red area of acute inflammation, like a flare. (more…)

Bioresonance Allergy Treatment: Can It Eliminate Your Allergy?

bioresonance allergy treatment
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…)

How to Treat Baby Eczema

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.

Food Intolerance Test - Which One is Best?

food intolerance test
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.

What is Extrinsic Allergic Alveolitis (Hypersensitivity Pneumonitis) ?

Hypersensitivity Pneumonitis
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.

Seasonal Allergic Reactions – Natural Relieve and Prevention

Each year, millions of people are susceptible to seasonal allergies symptoms. The pollen of the flowers float in the air that could be much more than a trigger allergies in some people. Pollen can cause allergic reactions that people can not take into consideration. Pollen can trigger an allergic reactions in patients with allergic rhinitis and asthma. (more…)
