text: Yo, check it out, I got a study to rap about
  Intrarenal blood flow, let me shout it out
  Used the 133Xe-washout technique, that's the plan
  Thirteen baboons, ligation of the common bile duct, damn
  
  Compared to sham-operated baboons, I found
  A decrease in blood distribution to the cortex, profound
  But the flow rate stayed the same, didn't budge
  Instead, I saw increased flow through the juxtameduallary circulation, no fudge
  
  Then I took five more baboons, treated them the same
  Infused noradrenaline, wanted to see the game
  They showed an enhanced pressor response, it was clear
  But when I used an alpha-blocker, it disappeared
  
  Phenoxybenzamine, that's the drug I used
  Blocked the alpha-adrenoreceptors, no more abuse
  Propranolol, the beta-blocker, didn't have an effect
  Noradrenaline infusion in sham-operated baboons, I had to inspect
  
  No enhanced response, no changes in sight
  Looks like the alterations are due to something right
  Renovascular sensitivity to catecholamines, that's the key
  Enhanced alpha-adrenoceptor activity, that's what I see
  
  So there you have it, the study's conclusion
  Obstructive jaundice messes with renal perfusion
  Increased sensitivity and alpha-adrenoceptor action
  That's the cause of the renal blood flow distraction
