Delayed Hypersensitivity Reaction to Poison Ivy Kaitlynn Webb AP2630 Dr. Romig Strongsville When a person comes into contact with poison ivy‚ they are almost guaranteed to break out into an itchy and annoying rash. This rash is a product of the body’s response from the reaction of the immune system called a delayed hypersensitivity reaction. This type of reaction generally takes between several to seventy-two hours to show symptoms. Symptoms of a hypersensitivity reaction include rash‚ pus around

Hypersensitivity ■ Exaggerated responses by an individual to an antigen following a previous exposure ■ Ag-ab reaction – release large quantities of chemicals‚ enzyme‚ and cell stimulators that are damaging to the host. ■ Traditionally classified based on time after exposure to offending antigen ❑ Immediate hypersensitivity – Ab mediated ❑ Delayed hypersensitivity – Cell mediated Types of Hypersensitivity Type I - ANAPHYLACTIC Type

Acute Systemic Anaphylaxis Anaphylaxis is a systemic allergic reaction involving the respiratory and/or the cardiovascular system; it has a rapid onset with the possibility of causing death. However‚ less severe reaction may be also defined as “anaphylaxis” if there is a high index of suspicion for allergic reaction in the setting of previously diagnosed allergy (Sanchez et al. 1999; Simons et al. 2007; Tang and Liew‚ 2008). It was observed by Simons (2006) that anaphylaxis is a disease of modern

Anatomy and Physiology Donna Loshbough Reeva Aggarwal January 23‚ 2014 Hodgkin Disease What is Hodgkin Disease? It is a type of lymphoma‚ lymphoma being a type of cancer originating in the lymphatic system. It is a cancer of the bone marrow and blood‚ and is one of the most curable cancers known to man. One of the first signs of Hodgkin disease is an enlarged lymph node‚ which may then spread. However‚ this type of cancer is highly treatable; the types of treatment include radiation and/or

PUTTING IT TOGETHER: Classifying Chemical Reactions Purpose: To observe and differentiate between the four different types of chemical reactions. Variables: The independent variables are the sodium chloride‚ sodium carbonate‚ magnesium‚copper‚ copper (11) sulfate‚ silver nitrate‚ oxygen‚ lead(11) nitrate‚ sodium carbonate‚ copper (11) sulfate pentahydrate. The dependent variables are the chemical reactions that are being looked for. For example decomposition‚ synthesis‚ single displacement or double

behind them. The term allergy/asthma is a collective term for the diseases: asthma‚ rhinoconjuctivitis‚ food allergies‚ atopic dermatitis‚ angioedema‚ urticaria‚ anaphylaxis‚ and insect and drug allergies (Holgate & Polosa‚ 2008). Cases of allergic reactions date all the way back to 3500 BC when Egyptian King Menses reportedly died from a bee sting. In the last 20 years the prevalence of allergies has doubled. Up to 40% of the world’s population has a predilection for developing allergies‚ while a third

RATE OF REACTIONS. The reaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. For example‚ the oxidative rusting of iron under the atmosphere is a slow reaction that can take many years‚ but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second (right). Chemical kinetics is the part of physical chemistry that studies reaction rates. The concepts
