Hypersensitivity I – immediate (onset 15-30 min) Affects - skin (urticaria and eczema, angioedema) - eyes (conjunctivitis) - nasopharynx (rhinorrhea, rhinitis), - bronchopulmonary tissues (asthma) - gastrointestinal tract (gastroenteritis) - Anaphylaxis Histology - Extrinsic/exogenous antigen - Antibody IgE - Mediated by mast cell and basophil - Lesion: mainly mast cell and eosinophil (also basophil, neutrophil) - Appearance: red, swollen Hypersensitivity II – cytotoxic (minute...

SUBJECT AND TASKS OF PATHOPHYSIOLOGY. GENERAL NOSOLOGY. ETIOLOGY AND PATHOGENESIS. 1.Pathophysiology is the science of: # &Vital functions of a sick human and animal organism. # Mechanisms of development of diseases. # Causes of disease # The conditions of development of disease. 2. The goal of pathophysiology is: # & Knowledge of the physiological mechanisms of the clinical manifestations of the disease. # Elimination of symptoms of the disease. # Checking disease‘s factors in anim...

Reversible Cell Injury Reversible injury is the stage of cell injury at which the deranged function and morphology of the injured cells can return to normal if the damaging stimulus is removed Two patterns of reversible cell injury can be observed under the microscope 1 Cellular swelling Occurs with impairment of the energy dependent Na ++/K ATP ase membrane pump, This will increase intracellular sodium and water accumulation 2 Fatty change Appearance of triglyceride containing li...

Chapter 1: The Cell as a Unit of Health and Disease • General Concepts o Pathology  The Greek word meaning suffering  Modern meaning “study of disease” • Understanding the cellular and molecular abnormalities that give rise to disease o Understanding NORMAL cellular structure and function is integral to understanding pathology  The focus of this initial lecture o “Physiologic process” generally means a normal process  Example – physiologic jaundice • Expect...

Hypertrophy - Increase in cell size - results in enlarged tissue mass Causes of hypertrophy - Additional work by the tissue Excessive hormonal stimulation Examples of hypertrophy - Enlarged heart resulting from increased demands Effect of consistent exercise on skeletal muscle, leading to an enlarged muscle mass Atrophy - Decrease in cell size - results in reduced tissue mass Causes of atrophy - Reduced use of the tissue Insufficient nutrition Decreased neurologic or hormonal ...

Description Briefly reflect on your pathophysiology experience and address the following questions: How will the knowledge of pathophysiology play into your career role?(nursing) What aspect of pathophysiology do you feel will be the most important moving forward? Pathophysiology Pathophysiology refers to abnormal functions in an individual or organ due to the disease process. In my nursing career, the knowledge of pathophysiology will serve as a hallmark of understanding the patients’ biol...

Define hypersensitivity Altered immunologic response to an antigen that results in disease or damage to individual (strong genetic linkage) 2 alternate names for type 1 hypersensitivity Immediate hypersensitivity or IgE mediated reactions most common allergic reactions are type 1 Mechanisms of type 1 response 1. Sensitizing exposure 2. Re exposure (immediate response and longer term response) Sensitizing exposure (type 1 mechanism) - Helper 2 t cells help b lymphocytes differentiate into plas...
