22
Q

Anti-inflammatory effect of glucocorticoids is caused by

A
  • Reducing the prostaglandin and leukotriene which results from inhibition of phospholipase A2

23
Q

True or False about anti-inflammatory effect of glucocorticoids. Anti-inflammatory effect of glucocorticoids results from inhibition of cyclooxygenase

FALSE

24
Q

True or False about anti-inflammatory effect of glucocorticoids. Anti-inflammatory effect of glucocorticoids results from inhibition of phospholipase A2 and reducing prostaglandin and leukotriene synthesis

A

TRUE

25
Q

True or False about anti-inflammatory effect of glucocorticoids. Induction of cyclooxygenase II expression which results in reducing amount of an enzyme available to produce prostoglandins

A

FALSE

26
Q

Immunosupressive effect of glucocorticoids is caused by

A

Reducing concentration of lymphocytes (T and B cells) and inhibiting function of tissue macrophages and
other antigen-presenting cells

True or False about anti-inflammatory effect of NSAIDs. Anti-inflammatory effect of NSAIDs results from inhibition of cyclooxygenase

A

TRUE

28
Q
