tumor necrosis factor -α and augmentation of inte rleukin -10

Reviewer:  Ulrich  Peitz  
 
Reviewer’s report:  
 
The authors have choosen an interesting subject and performed an elaborated animal experiment. 
They used sophisticated molecular determinations to provide evidence that induction of Heme 
Oxygenase -1 might be protective in severe acute pancrea titis.  
 
I have some concerns.

Abstract  
 
It should be mentioned in the abstract which species of animals were used.  
 
 
Methods  
 
Effects of hemin and ZnPP on rats without induction of acute pancretitis were not tested as 
control. This should be commented on.  
 
 
Results  
 
The authors refer to "hemin pretreatment", but hemin was administered 30 minutes after 
induction of pancreatitis.

Background  
 
It is clear that such a common disease associated with mortality up to 30% in severe cases

If this inflammation is marked, it would lead to inappropriate activation of immune system 
demonstrating as systemic inflammatory response s yndrome(SIRS) and eventually result in 
multiple organs dysfunction syndrome(MODS) [3].
