Reviewer’s report  
Title: Synergistic effect of κ-carrageenan on oxazolone -induced inflammation in BALB/c mice  
 
Version: 1 Date: 29 Dec 2015  
 
Reviewer: Guillaume Bouguen  
Reviewer’s report:  
Overall, I agree with the substantial modification made by the authors after the first revision and 
I have only minor comments  
 
1- This is finally an observational study and authors did not study the mechanistic aspect of 
carragean. It would be interesting for discussion that the author discussed the main way 
of action of carragean responsible for increasing ongoing mucosal inflamm ation. Since 
activation of TLR4 could increase and activate NFKB pathway, increase expression of 
TLR4 (and thus sensitivity to LPS) by carragean could be the main effect and the other 
observations only a consequence. This should be discuss  
 
2- Please update reference according to author guidelines  
 
3- Figure and Table should be understood without the text and abbreviations have to be 
explain in legends  
 
4- There is some grammatical mistakes of the revised text that should be corrected.  
 
Are the methods appropriate and well described?  
If not, please specify what is required in your comments to the authors.  
 
Yes 
 
Does the work include the necessary controls?  
If not, please specify which con trols are required in your comments to the authors.  
 
Yes 
 
Are the conclusions drawn adequately supported by the data shown?  
If not, please explain in your comments to the authors.  
 
Yes 
 
Are you able to assess any statistics in the manuscript or would you r ecommend an 
additional statistical review?  
If an additional statistical review is recommended, please specify what aspects require further 
assessment in your comments to the editors.  
 
I am able to assess the statistics
