ABSTRACT
Aim To assess the effect and mechanism of N acetylcysteine (NAC, antioxidant) on nuclear factor ?B (NF ?B) in lung tissue and bronhial alveolar lavage fluid(BALF) of rats undergoing acute and chronic smoking. Methods All Wistar rats were divided randomly into three groups control group, smoking group and intervention group. The latter two groups were applied to observing NF ?B expression during different periods (1, 2, 7, 14, 60d). Western Blot assay was used to analyze the activation of NF ?B. Results The first and second day the expression of NF ?B in lung tissue ( 36.9 ? 8.1 and 36.9 ? 8.0 )and in BALF( 24.0 ? 6.1 and 21.2 ? 5.8 ) rose significantly comparing with that in the control groups ( 7.3 ? 2.8 and 5.7 ? 2.6 )respectively (P
