Effect of simvastatin on MMPs and TIMPs in cigarette smoke-induced rat COPD model
BACKGROUND Proteases may play an important role in the development of chronic obstructive pulmonary disease and emphysema in response to cigarette smoke exposure (CSE). The current study was designed to investigate the expression of matrix metalloproteinase (MMP)-8, MMP-9, MMP-12, tissue inhibitor of MMP (TIMP)-1, and TIMP-4 in rat lung tissues in response to CSE, and assessed the effect of sim...
متن کاملSimvastatin mitigates functional and structural impairment of lung and right ventricle in a rat model of cigarette smoke-induced COPD.
OBJECTIVES This study is conducted to investigate an effect of simvastatin on cigarette smoke-induced COPD. METHODS Rats were exposed to air (control) and cigarette smoke (smoking) in presence and absence of simvastatin. Heart and lung tissues were harvested for histopathologic and morphometric analysis. Body weight of rat, mean liner intercept (MLI), mean alveolar number (MAN), lung function...

15 صفحه اولAnimal models of cigarette smoke-induced COPD.
OBJECTIVES To review the animal models of COPD, and to compare these data to those found in humans. RESULTS Smoke-induced animal models can produce emphysema, although the lesions are not generally close mimics of human emphysema, as well as increases in mucous-secreting cells and vascular changes including pulmonary hypertension. There is considerable species-to-species variation in the degr...
متن کاملPaeoniflorin Attenuated Oxidative Stress in Rat COPD Model Induced by Cigarette Smoke
Paeoniflorin (PF), a monoterpene glucoside, might have an effect on the oxidative stress. However, the mechanism is still unknown. In this study, we made the COPD model in Sprague-Dawley (SD) rats by exposing them to the smoke of 20 cigarettes for 1 hour/day and 6 days/week, for 12 weeks, 24 weeks, or 36 weeks. Our findings suggested that smoke inhalation can trigger the oxidative stress from t...
