Intracellualr and extracellular errors of metabolism of lipid, lipidoses, erros of carbohydrtae metabolism Flashcards
lipid staining methods
steatosis: lipid within membrane bound liposomes of perenchymal cells
SUDAN STAINS AND OSMIUM TETTROXIDE
what is fatty liver also known as
steatorrhoeic hepatosis or steatosis heptais
what is fatty liver
reversible condition where large vacouled of TAG fat accumulate in liver cells
what can oversupply come from
obesity, insulin resistance or alcoholism,
also nutrient malnutristion can cause the mobilization of fat from adipocytes and create local oversupply in liver
some other: metabolic syndrome-diabetes, hypertension, dyslipidemia
metabolic causes of steatosis
- a-betalipoproteniemia
- glycogen storage disease
-weber-christian disease - wolmans disease
-acute fatty liver of pregnancy
-lipodystrophy
nutritional causes of steatosis
- malnutrition
- total parenteral nutrition
- severe weight loss
-refeeding syndorme
-jejubo-ileal bypass
-gastric bypass - jejunal diverticulosis with bacterial overgrowth
drugs and toxins causes of steatosis
-amiodarone
methotrecte
-dilitazem
-highly active antitetrovital therapy
-glucicorticoids
-tamoxifen
-enviromantal heptatotoxins-phosphorus, toxis mushroom
other causes
inflammatory bowel disease or HIV
peripheral fatty metamorphosis
due to intocification of amanita ohaloides-death angel
central fatty metamorphosis in liver
right circulatory failure
tocix intracellular steatosis
diphteric myocarditis
lipomatosis is
fatty infiltration within interstital tissue or increase in adipos cells and infiltration into the tissues and organs
most frequent examples of lipomatosis
- atrophia lipomatosa cordis
- pseudohypertrophya lipomatosa pancreatis
- pseudohypertrophya lipomatosa renis
lipidoses is
lipid storage disease
- group of inherited metabolic disorders where harmful amount of lipids accumulate on some cells and tissues.
- dont produce enough enxymes needed for metaboliszation or the produce some that dont work correctly
lipidoses causes damage in
brain, peripheral nervous system, liver, spleen, bone marrow
