Document Summary
Immune system responds to something: epitopes of molecules from pathogens. Immune system remembers that material: memory cells. Subsequent exposure produces reacion: protecion from pathogens, allergy to harmless material. Cold- like symptoms: associated with the innate immune system, some people get a geographic tongue. Atopic dermaiis from surface exposure: comes from skin contact. Dose makes the poison --> the amounts are what is important. Its a response to the powders, not the speciic powder. Exposure to lg amounts of powder (factory"s, bakers etc) Latex gloves and condoms: there are alternaives today. Nickel alloys are common (zippers, belt buckles, ear rings, coins etc) Many piercings made of stainless steel: stainless steel may contain nickel. Matresses can contain lg amounts of droppings. Most reacions are due to pet saliva. Gets on their fur when they lick themselves. Allergy: immune system reacts to the food. Intolerance: substance in food produce adverse reacion. Lactase is available as a supplement: breaks the lactose down into glucose.
