The study "A New Method to Induce Nonalcoholic Steatohepatitis (NASH) in Mice" has a 
descriptive approach about different diets to induce NAFLD. It was well cond ucted and written, 
regarding some crucial tools to conduct the conclusion. The authors, also investigated the action 
of cigarette smoke in every experimental models included in this study, as a co -factor for hepatic 
damage. None important intervention is n eeded to publication by this journal. However, any 
mechanism pathway was investigated to better elucidate the obtained data, specially in concern 
about the relation of cigarette smoke and the increased risk to hepatic lesions in some diet tested.   
About t he cigarette smoke model used in this study, I recommend a better explanation about the 
employed dose of 4 cigarettes/day, once it can be consider a low smoking load to develop 
chronic diseases.  
 
Some minor corrections can be done.  
On pdf page 11, line 1 1: use "serum level" instead of "Serum level".  
On page 12, line 17: use "inflammation"instead of "Inflammation". Add a dot after "(central 
vein)".
