Clinical signal simptoms

1.Labil cells rapid prolif gut lining

and turn over apitelial cells2.Stable cells slow-prolif

hepatocyt and turn over

3.Permanent cells not able to prolif neurones

1. Reduced oxygen supply2. Physical agents3. Chemical agents4. Micro organism5. Abnormal immunologic rx6. Nutritional deficiency7. Genetic abnormalities

4 major aspecs : 1. Etiologi 2. Pathogenese 3. Morphologic changes 4. Functional changes (clinical sign &

symp)

Physiological proliferation : 1. In somatic growth during fetal

development2.Regeneration : blood cells, mucosa

cells, skin cells (rapid cell turn over)3.Slower cell turn over : liver tissue,

kidney, etc.

1. Increase in size of individual cellshypertrophy

2. Increase in the number of cellshyperplasia

3. More common : combination 1&2

A. Physiological enlargement : muscle, uterus, breast

B. Pathological enlargement :result of disease processeg: increased myocardial cell

Hipertropi : myocardium (enlargement of the heart)

Hiperplasia : - chronic iritation : skin in chronic inflamation- imbalance of hormonal activity : prostat in old age

Hipertropi : myocardium (enlargement of the heart)

Hiperplasia : - chronic iritation : skin in chronic inflamation- imbalance of hormonal activity : prostat in old age

Metaplasia : change from one type to another (frequently associated with hiperplasia) in lining epithelia or in conective tissue.

Displasia :disordered growth (frequently precursor of malignancy)e.g : uterine cervic

1. Progressive : from few cells large tumor

2. Purposeless : irregular, unstructured3. Effects on surrounding tissue : compreses4. Not related to needs of the body : distruction5. Parasitic : blood supply
