text: Yo, check it out, let me break it down for you
  Prostaglandin synthesis in the cells, it's true
  Endothelial cells be gettin' things started
  Exogenous substrate, like arachidonic acid, added
  Thrombin and A23187, the CA2+-ionophore
  They make prostacyclin from the body's own store
  
  We noticed somethin' interestin', gotta mention
  When thrombin and arachidonic acid, they be in combination
  The endothelial cells, they produce twice the dose
  Compared to arachidonic acid alone, that's how it goes
  
  Thrombin-induced conversion, it's a crucial part
  But exogenous arachidonic acid plays a part
  It inhibits the conversion of the endogenous kind
  But stimulates the conversion of arachidonic acid, you'll find
  
  The enzymes involved, they get activated
  Prostacyclin synthesis, it's accelerated
  Lastin' 'bout 5 minutes, that's the duration
  Phospholipase inhibitors, they bring the inhibition
  
  Mepacrine and p-bromophenyl-acylbromide, they do the trick
  But dibutyryl cAMP, it don't stick
  It can't stop arachidonic acid release
  From the cellular phospholipids, that's the beast
  
  Thrombin and Ca2+-ionophore, they got more to show
  They not only release endogenous substrate, yo
  They activate the enzyme system, it's clear
  Transformin' arachidonic acid, makin' it all premiere
