Ambient particulate air pollution from vehicles promotes lipid peroxidation and inflammatory responses in rat lung BJMBR
Pereira,C.E.L.; Heck,T.G.; Saldiva,P.H.N.; Rhoden,C.R..
Oxidative stress plays a major role in the pathogenesis of particle-dependent lung injury. Ambient particle levels from vehicles have not been previously shown to cause oxidative stress to the lungs. The present study was conducted to a) determine whether short-term exposure to ambient levels of particulate air pollution from vehicles elicits inflammatory responses and lipid peroxidation in rat lungs, and b) determine if intermittent short-term exposures (every 4 days) induce some degree of tolerance. Three-month-old male Wistar rats were exposed to ambient particulate matter (PM) from vehicles (N = 30) for 6 or 20 continuous hours, or for intermittent (5 h) periods during 20 h for 4 consecutive days or to filtered air (PM <10 µm; N = 30). Rats...

Effects of atropine and propranolol on lung inflammation in experimental envenomation: comparison of two buthidae venoms J. Venom. Anim. Toxins incl. Trop. Dis.
Saidi,Hadjer; Adi-Bessalem,Sonia; Hammoudi-Triki,Djelila; Laraba-Djebari,Fatima.
Background Previous works had shown that scorpion venom induced neurotransmitter elevation and an inflammatory response associated with various anatomo-pathological modifications. The most dangerous scorpions species in Algeria responsible for these effects are Androctonus australis hector (Aah) and Androctonus amoreuxi (Aam). Results Comparison of the physiopathological effects induced by the two venoms showed differences in the kinetic of cytokine release and in lung injury. The lung edema was only observed in response to Aah venom and it was correlated with cell infiltration. In order to better understand the involved mechanism in inflammatory response, we used two antagonists, atropine (non-selective muscarinic antagonist) and propranolol (β adrenergic...
