Q

what can oversupply come from

A

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

lipidoses is

A

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

Q

most common lysosomal storage disease

A

gaucher disease

17
Q

Gaucher disease

A

deficiency of glucocerebrosidase–>acc of glucocerebroside/glucosylceramide

can happen in spleen, liver, kidney, lungs, brain, BM

autosomal recessive ingeritance

18
Q

symtoms of gaucher

A
  • enlrged spleen and liver
  • liver malfunction
  • skeletal disorders
  • bone lesions
  • pain, severe neurologic complication, swelling of Lymphnodes and maybe some near joint, distended abdomen, brownish tint to skin, anemia, low blood platelets, yelloe fatty deposits on the sclera
19
Q

niemann-pick disease

A

inheritted condition whre harmful amount of lipids accumulate in spleen, lungs, BM and brian

autosomal recessive

caused by mutation on NPC1, NPC2, SMPD1 genes (sphingomyelin phosphodiesterase)

20
Q

no lysosmal liposidoses

A

familial hyperlipoproteinemia

xanthomatous

tangier disease

21
Q

what is used to identify glycogen

A

PAS and water

22
Q

what is diabetes

A

metabolic disorder characterized by hyperglycemia (^blood sygar) resulting form low lvls of insulin or resistance of insulin effects

23
Q

symtomps of DM

A

polyuria, polydipsia(thrist and fluid intake), blurred vision

24
Q

DM 1

A

-autoimmune disease–>destruction of insulin producing beta cells
- injection
- not primarly childhood problem

25
Q

DM 2

A
  • non insulin dependent
  • obesty
  • insulin resistance, insulin deficiency and hyperglycemia

hyalinosis iof istelts of langehans

26
Q

Gestational diabetes (GDM

A

affect pregnant women

reduces insulin sensitivyt

27
Q

complications of dm

A

dibaetic ketoacidosis

non ketoic hyperosmolar coma

hypoglycemia

diabetic coma

28
Q

chronic complications of dm

A

-vascular disease
- ^blood glucose–>angiopathy
- endithelial cells lining the vv take in more glucosa–>surface glycoprotien –>Basement membrane grow thicker and weaker
