S.- Evidences of Herbal Medicine-Derived Natural Products Effects in Inflammatory Lung Diseases(2016) SANTANA, Fernanda Paula R.; PINHEIRO, Nathalia M.; MERNAK, Marcia Isabel B.; RIGHETTI, Renato F.; MARTINS, Milton A.; LAGO, Joao H. G.; LOPES, Fernanda D. T. Q. dos Santos; TIBERIO, Iolanda F. L. C.; PRADO, Carla M.Pulmonary inflammation is a hallmark of many respiratory diseases such as asthma, chronic obstructive pulmonary disease (COPD), and acute respiratory syndrome distress (ARDS). Most of these diseases are treated with anti-inflammatory therapy in order to prevent or to reduce the pulmonary inflammation. Herbal medicine-derived natural products have been used in folk medicine and scientific studies to evaluate the value of these compounds have grown in recent years. Many substances derived from plants have the biological effects in vitro and in vivo, such as flavonoids, alkaloids, and terpenoids. Among the biological activities of natural products derived from plants can be pointed out the anti-inflammatory, antiviral, antiplatelet, antitumor anti-allergic activities, and antioxidant. Although many reports have evaluated the effects of these compounds in experimental models, studies evaluating clinical trials are scarce in the literature. This review aims to emphasize the effects of these different natural products in pulmonary diseases in experimental models and in humans and pointing out some possible mechanisms of action.
- Structurally Related Monoterpenes p-Cymene, Carvacrol and Thymol Isolated from Essential Oil from Leaves of Lippia sidoides Cham. (Verbenaceae) Protect Mice against Elastase-Induced Emphysema(2016) GAMES, Ellen; GUERREIRO, Marina; SANTANA, Fernanda R.; PINHEIRO, Nathalia M.; OLIVEIRA, Emerson A. de; LOPES, Fernanda D. T. Q. S.; OLIVO, Clarice R.; TIBERIO, Iolanda F. L. C.; MARTINS, Milton A.; LAGO, Joao Henrique G.; PRADO, Carla M.Background: Chronic obstructive pulmonary disease (COPD) is characterized by irreversible airflow obstruction and inflammation. Natural products, such as monoterpenes, displayed anti-inflammatory and anti-oxidant activities and can be used as a source of new compounds to COPD treatment. Our aim was to evaluate, in an elastase-induced pulmonary emphysema in mice, the effects of and underlying mechanisms of three related natural monoterpenes (p-cymene, carvacrol and thymol) isolated from essential oil from leaves Lippia sidoides Cham. (Verbenaceae). Methods: Mices received porcine pancreatic elastase (PPE) and were treated with p-cymene, carvacrol, thymol or vehicle 30 min later and again on 7th, 14th and 28th days. Lung inflammatory profile and histological sections were evaluated. Results: In the elastase-instilled animals, the tested monoterpenes reduced alveolar enlargement, macrophages and the levels of IL-1 beta, IL-6, IL-8 and IL-17 in bronchoalveolar lavage fluid (BALF), and collagen fibers, MMP-9 and p-65-NF-kappa B-positive cells in lung parenchyma (p < 0.05). All treatments attenuated levels of 8-iso-PGF2 alpha but only thymol was able to reduced exhaled nitric oxide (p < 0.05). Conclusion: Monoterpenes p-cymene, carvacrol and thymol reduced lung emphysema and inflammation in mice. No significant differences among the three monoterpenes treatments were found, suggesting that the presence of hydroxyl group in the molecular structure of thymol and carvacrol do not play a central role in the anti-inflammatory effects.
- Creatine supplementation attenuates pulmonary and systemic effects of lung ischemia and reperfusion injury(2016) ALMEIDA, Francine Maria; OLIVEIRA-JUNIOR, Manoel Carneiro; SOUZA, Renato Aparecido; PETRONI, Ricardo Costa; SOTO, Sonia Fatima; SORIANO, Francisco Garcia; CARVALHO, Paulo Tarso Camillo de; ALBERTINI, Regiane; DAMACENO-RODRIGUES, Nilsa Regina; LOPES, Fernanda Degobbi Tenorio Quirino Santos; CASTRO-FARIA-NETO, Hugo Caire; MARTINS, Milton Arruda; DOLHNIKOFF, Marisa; PAZETTI, Rogerio; VIEIRA, Rodolfo PaulaBACKGROUND: Creatine (Cr) is a dietary supplement that presents beneficial effects in experimental models of heart and brain ischemia and reperfusion (I/R) injury. It can improve adenosine 5'-triphosphate generation and reduce cell damage This study evaluated the effects of Cr supplementation in a model of lung PR. METHODS: Forty male Wistar rats were divided into 4 groups: sham operated, Cr+sham, I/R, and Cr+I/R. We investigated the effects of 5 days of Cr supplementation (0.5 g/kg/day by gavage) before left pulmonary artery ischemia (90 minutes) and reperfusion (120 minutes) on pulmonary and systemic response. RESULTS: Cr inhibited the I/R-induced increase in exhaled nitric oxide (p < 0.05), total cells (p < 0.01), and neutrophils (p < 0.001) in bronchoalveolar lavage fluid and in the systemic circulation (p < 0.001). The levels of interleulcin-1 beta (p < 0.05), tissue damping, and tissue elastance (p < 0.05) were also minimized Cr also inhibited pulmonary edema formation (total proteins in bronchoalveolar lavage fluid, p < 0.001; histologic edema index, p < 0.001) and neutrophils accumulation in lung tissue (p < 0.001). As possible mechanisms underlying Cr effects, we observed a reduced expression of caspase 3 (p < 0.05), reduced expression of Toll-like receptor (TLR) 4, and increased expression of TLR7 in lung tissue (p < 0.001). CONCLUSIONS: Cr supplementation presents pulmonary and systemic protective effects in acute lung injury induced by I/R in rats. These beneficial effects seem to be related to the anti-inflammatory and antioxidant properties of Cr and modulation of TLRs.
