(a) DNA migration (mm) in the lung tissues evaluated by a comet assay, 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) Cleaved caspase-3 concentration 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 .
