1、病理生理学Pathophysiology山东大学医学院病理生理学教研室,IntroductionPathophysiology:The ology is to study the mechanisms of the occurrence,development and outcome of the diseases Pathological anatomy Pathology Pathophysiology The alteration function Pathophysiologyin process of metabolismdisease structure Pathological

2、anatomy,for example:bronchial alveolar edema structure congestionlobar pneumonia function hypoventilation,metabolism diffusion impairment hypoxia,acidosis,shockThe task,position and content of pathophysiologyThe methods of investigationThe history,Introduction of disease.concept of disease causes di

3、sturbances abnormal conditions of homeostasis life process.causes and conditions of disease cause(etiology):condition:inducing factor(precipitating factor):,for example pneumococcal pneumonia cause(etiology):pneumococcus condition:cold,tired pulmonary tuberculosis cause:tubercular bacillus condition

4、:worry,malnutrition.pathogenesis of disease It studies how the etiology can cause the disease in the body.,1.The general rule of pathogenesis in disease damage and anti-damage damage:defence anti-damage adaptation compensation for example:food poisoning toxin vomiting,diarrhea(damage)(anti-damage)tr

5、auma:The dual nature of response of anti-damage:,reverse of cause-result reverse cause result cause result for example:food toxication diarrhea dehydration low blood volume acidosis shock part and whole,2.The basic pathogenesis nervous mechanism injury of nervous system cause disease disturbance of

6、the function injury:epidemic meningitis,cephalitis,poliomyelitis functional hypertension,disturbance:hepatic encephalopathy,humoral mechanism pathogenic alteration of the volume and agent activity of humoral factors disturbance of the homeostasis disease hormone humoral general humoral factor factor

7、 local humoral factor cellular factor,the acting endocrine paracrine manner of humoral factor:autocrine,cellular mechanismcause damage of cells disease mitochondria cause lysosome,for example:injury of cell membrane cellular edema free injury of mitochondria ATP radical injury of lysosome autolysis
