GHEORGHE RAFTU, GETA MITREA, LUANA ANDREEA MACOVEI, AUREL NECHITA CHEMICAL ADDITIVES FROM THE COMPOSITION OF PLASTIC PRODUCTS AND OTHER MATERIALS IN ESTABLISHING DIAGNOSIS FOR ALERGY DISEASE Many of the chemical additives in the plastic products, besides the possible safety problems that may arise during the production process, have negative effecty, too, on the environment and human health. Plastic is a synthetic polymer. The polymers include starch, latex and cellulose, combined with different substances and chemicals, used in various formulas, the polymer is included in the naylon. At high temperatures such as microwave oven temperature, polymers can migrate from the packaging plastic in food. In most cases, establishing the diagnosis of allergic disease is a complex and difficult operation. This difficulty is primarily related to the polymorphism of the clinical manifestations accompanying allergic reactions, the existence during the evolution of these conditions, of long clinical asymptomatic latencies, as well as due to numerous subjective and objective symptoms that overlap with those caused by the allergen, complicating and altering the clinical picture. Allergies are an abnormal reaction of the body to allergens and develop in two stages. After the first contact with the allergen, the IgE antibodies are produced, and the second contact produces the allergic reaction. The produced antibodies will release the chemical mediators (histamine, prostaglandine, etc.) which cause an inflammatory response, vascular changes and irritation of the tissues, with the appearance of symptoms specific to allergy: redness, rash, itching, edema, etc.The so complex symptom of allergic diseases comprises several systems and organs at the same time, and the existence of over-additive phenomena makes it impossible to have characteristic clinical symptoms of allergic diseases that allow their identification only by clinical examination. However, this does not mean that the clinical exam and the analysis of the various objective and subjective symptoms presented by the patient is of no importance in establishing the diagnosis and recognizing the allergic character of the disease.The study includes a number of patients studied at the Galati Allergy Clinic. Specific immunotherapy known as desensitization or anti-allergic vaccination, is designed to fight the causes of allergies that occur when the immune system misinterprets harmless substances. Clinical examination results are complemented by allergen and specific antibody research; skin tests are the most common method for allergen detection.
