Comparative Study on Pulmonary Toxicity in Mice Induced by Exposure to Unflavoured and Apple- and Strawberry-Flavoured Tobacco Waterpipe Smoke

Figure 6

(a) Total nitric oxide (NO) activity in lung homogenate, at the end of a one-month exposure period to either air (control, ) or plain (P-) waterpipe smoke (WPS, ) or apple-flavoured (AF-) WPS () or strawberry-flavoured (SF-) WPS (). (b) Catalase activity in lung homogenate, at the end of a one-month exposure period to either air (control, ) or plain (P-) waterpipe smoke (WPS, ) or apple-flavoured (AF-) WPS () or strawberry-flavoured (SF-) WPS (). (b) Catalase and (c) reduced glutathione (GSH) concentrations in lung homogenate, at the end of a one-month exposure period to either air (control, ) or plain (P-) waterpipe smoke (WPS, ) or apple-flavoured (AF-) WPS () or strawberry-flavoured (SF-) WPS (). Data are expressed as .
