Metabolism part 2 Flashcards
Indicate the causative factors of serous inflammation & describe the morphological features of this type of inflammation.
Transparent fluid
3-5 % protein
Low cell count
Due to viruses, toxins, physical damage, early bacterial infection
characterise the microscopic morphological features of stomach ulcer disease
Necrotic debris, nonspecific acute and chronic infiltration, granulation tissue
describe the morphological features of purulent inflammation & characterize the main forms of this type of inflammation
*consists of plasma with both active and dead neutrophils,fibrinogen and necrotic parenchymal cells
*Bacterial infection
*Forms:
– Abscess
– Phlegmona
– Empyema
characterise the pathogenesis mechanism of stomach ulcer disease.
what causes peritonitis.
Infection, bile, HCl
difference between ulcers of stomach & duodenum.
Gastric ulcers => lining of stomach
Duodenal ulcers => lining of duodenum
what organs can stomach ulcer penertrate?
Pancreas and liver
Pathogenesis of appendicitis
Microorganisms trigger inflammation after epithelium
Damage by:
*Luminal obstruction, dyskinesia and coprastasis.
*Intravascular stasis
*Hyperergic reaction
What kind of liver tumours do you know
Hepatocellular carcinoma
Precancerous changes?
- chronic erosions and ulcers
- polyps, chronic inflammation
- intraepithelial neoplasias
- carcinoma in situ
Pathogenesis of endoinfections
- Age related factors
- evolutionary (newborns)
- involutionary (elderly)
*HIV, TBC, entorovirosis, typhoid fever, shigellosis, - intestinal dyskinesia
- immunosuppressants
• Congenital anomalies that weaken immune system and worsens resistance to microorganisms. - Enterocytic outer membrane dysfunction
- Cellular and humarol immunity failure
- Digestive tract dysplasia’s: Megacolon, dolichosigma, di-verticulum
