Beneficial effects of N-acetylcysteine on protease-antiprotease balance in attenuating bleomycin-induced pulmonary fibrosis in rats
Objective(s): The role of N-acetylcysteine (NAC) as an anti-oxidant in attenuating bleomycin-induced pulmonary fibrosis has been reported. However, its effect on parenchymal remodeling via regulating the protease-antiprotease balance is not fully defined. Therefore, the present study was designed to explore the possible role of matrix metalloproteinases (MMP), tissue i...
متن کاملReduction of bleomycin-induced pulmonary fibrosis by serum amyloid P.
Fibrotic diseases such as scleroderma, severe chronic asthma, pulmonary fibrosis, and cardiac fibrosis kill tens of thousands of people each year in the U.S. alone. Growing evidence suggests that in fibrotic lesions, a subset of blood monocytes enters the tissue and differentiates into fibroblast-like cells called fibrocytes, causing tissue dysfunction. We previously found that a plasma protein...
متن کاملSerum Amyloid P Therapeutically Attenuates Murine Bleomycin-Induced Pulmonary Fibrosis via Its Effects on Macrophages
Macrophages promote tissue remodeling but few mechanisms exist to modulate their activity during tissue fibrosis. Serum amyloid P (SAP), a member of the pentraxin family of proteins, signals through Fcgamma receptors which are known to affect macrophage activation. We determined that IPF/UIP patients have increased protein levels of several alternatively activated pro-fibrotic (M2) macrophage-a...
متن کاملEarly and late preventive effect of Nigella sativa on the bleomycin-induced pulmonary fibrosis in rats: An experimental study
Objective: Pulmonary fibhrosis is a disease of the connective tissues in the respiratory system. Nigella sativa has been used for the treatment of pulmonary diseases like asthma. This study investigated the early and late preventive effect of methanolic extract of N. sativa on a bleomycin- induced pulmonary fibrosis model. Materials and Methods: This study was carried out using 52 rats. Pulmona...
متن کاملSaffron Protection against Bleomycin-Induced Pulmonary Fibrosis in Rats
Background: Bleomycin-induced lung fibrosis has been accepted as an animal model for fibrosis in rats. The aim of this study was to evaluate the effects of saffron aqueous extract on this disorder paving the way for more investigation in treating idiopathic pulmonary fibrosis in human. Methods: Male Wistar rats (250–300 gr) were instilled a single dose of bleomycin (5 mg/kg) via in...
