Question 1

What is PSE?

Answer 1

pale, soft & exudative pork syndrome –> genetic susceptibility, seen after & during slaughter

Question 2

What is DFD?

Answer 2

dark, firm & dry pork syndrome –> prolonged transport, starvation before slaughter. Both produce lactic acid

Question 3

What are the variations of microcirculation in local acute inflammation?

Answer 3

• vasoconstriction -> caused by serotonin
• vasodilation -> histamine, bradykinin, prostaglandins, vascular change ( –> exudate formation)
• increased vascular permeability -> by histamine & serotonin (–> fluid accumulates in tissues, swelling)
• passive hyperemia

Question 4

What is hypotonic dehydration?

Answer 4

• loss of water lower than loss of electrolytes
  Volume of ECF goes down & ICF goes up
  Osmolality of ECF & sodium content decrease
  PCV, concentration of haemoglobin & PLASMA PROTEINS ARE INCREASED
  CAUSE: diarrhoea, sweating (eq), vomiting, renal insufficiency, Na loss

Question 5

What is hypertonic dehydration?

Answer 5

• loss of water is higher than electrolytes
  Volume of ECF goes down
  Volume of ICF goes down
  OSMOLALITY OF NA & ECF INCREASED
  CASUSES: failure in water intake, fever, diabetes insidious

Question 6

What is isotonic dehydration?

Answer 6

• loss of water is equal to electrolytes
  Volume of ECF goes down
  Volume of ICF no change
  CAUSES: diarrhoea, vomiting, bleeding, lactic acidosis, dislocation od abomasum, burns
