Pulmonary fibrosis (PF) is a chronic and progressive condition of lung disease characterized by reduced numbers and increased stiffness of air sac in the lungs (alveoli), affecting the lung breathing function to provide enough oxygen into the bloodstream
Green tea, is a precious drink processed numbers of health benefit known to almost everyone in Asia and Western world.
In the evaluation of green tea extract efficacy in pulmonary fibrosis caused by direct injury due to over expression of oxygen free radicals and inflammatory cells and fibroblasts in mice model with injection of Paraquat (0.3 mg/kg) into the right lungs of rats, after 2 weeks, then assigned the tested mice to group treated by green tea extract or non treatment groups and control group treated by saline, after assessment, researchers found that
levels of malondialdehyde (MDA), an indication of over expression of free radicals in induction of oxidative stress caused by ROS chain reaction and endothelin (ET)-1, and prepro-ET-1 mRNA expression, a strong indication of the endothelium signals of vasoconstriction and local cellular growth and survival of air sac cells in the lungs (alveoli).
*In compared to non treatment and saline groups, green tea administered 1% GTE mixed with feed group showed significant decreases in pulmonary fibrosis, along with decreases in MDA, ET-1, and prepro-ET-1 mRNA expression
Additional study of the neutrophils in the site of infection in initiation of host defense and inflammation in precipitation of pulmonary fibrosis development by the Medical School of Padova, revealed that application of green tea (-)epigallocatechin-3-gallate (EGCG) strongly inhibits neutrophil elastase by repressing the reactive oxygen species activity in induction of apoptosis of activated neutrophils.
In vitro, administration of EGCG dramatically inhibited chemokine expression, a secondary pro-inflammatory mediators induced by primary pro-inflammatory in activated neutrophil chemotaxis in migration of neutrophils of immune system to the site of infection.
Importantly, injection of green tea EGCG also demonstrated a significant effect by blocking neutrophil-mediated angiogenesis in vivo by initiated growth of new blood vessels to stimulate and fuel the ongoing lung cell damage and death of the cell in the alveoli.
These results constituted a substantial and protective effect in enhanced resolution in a pulmonary inflammation model and significantly reduced consequent fibrosis.
Dr. Donà M, at the end of the analysis said, "These results provide molecular and cellular insights into the claimed beneficial properties of green tea and indicate that EGCG is a potent anti-inflammatory compound with therapeutic potential".
According to the study, application of curcumin (200 mg/kg b.w), GTE (150 mg/kg b.w), and NAC (490 mg/kg b.w) orally for 14 days with concomitant administration of cyclophosphamide (CP), revealed a strong activity in inhibited oxidative stress and lung myelo-peroxidase activity observed in animals of the CP group.
Treatment group also decreased the levels of N-acetyl-β-d-glucosaminidase, leukotriene C₄, and protein in bronchoalveolar lavage fluid (BALF) in demonstration of over reaction of immune response in induction of inflammation through inhibited production of proinflammatory cytokines (growth factor-β, interleukin -1β, and histamine) in initiated lung injure and induced apoptosis of lung cells.
