(a) Interleukin-6 (IL-6) 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 (). (b) Tumor necrosis factor-α (TNFα) 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 ().
