6.Just under 3 feet in diameter and weighing 45 pounds, the black circular device emits an intense 15- to 30-degree-wide acoustic beam -- a high-pitched shrill tone similar to a smoke detector alarm -- that can easily cause permanent auditory damage at close range.
7.The pathogenesy of smoke inhalation acute lung injury/acute respiratory distress syndrome(ALI/ARDS) is not completely clear,perhaps concerned with oxidative damage,the change of pulmonary surfactant and cytokine,and apoptosis.
8.[Methods]Deoxyribose(DR)degradation and plasmid DNA methods were used to determine oxidative damage of aqueous cigarette smoke solution(ACSS)and effects ofβˉcarotene.
9.AIM: To investigate DNA damage and cell stress (heat shock protein 70 expression) in human bronchi smooth muscle cells by cigarette smoke extract (CSE) in vitro.
