Idiopathic pulmonary fibrosis is a progressive fatal lung disease characterized by excessive collagen deposition, with no effective treatments. We investigated the efficacy of natural products with high anti-inflammatory activity, such as passion fruit peel extract (PFPE), in a mouse model of bleomycin-induced pulmonary fibrosis (PF). C57BL/6J mice were subjected to a single intratracheal instillation of bleomycin to induce PF. Daily PFPE treatment significantly reduced loss of body mass and mortality rate in mice compared with those treated with bleomycin. While bleomycin-induced PF resulted in elevated total numbers of inflammatory cells, macrophages, lymphocytes, and neutrophils in bronchoalveolar lavage fluid on both days 7 and 21, PFPE administration significantly attenuated these phenomena compared with bleomycin group. On day 7, the decreased superoxide dismutase and myeloperoxidase activities observed in the bleomycin group were significantly restored with PFPE treatment. On day 21, enhanced hydroxyproline deposition in the bleomycin group was also suppressed by PFPE administration. PFPE treatment significantly attenuated extensive inflammatory cell infiltration and accumulation of collagen in lung tissue sections of bleomycin-induced mice on days 7 and 21, respectively. Our results indicate that administration of PFPE decreased bleomycin-induced PF because of anti-inflammatory and antioxidant activities.

In traditional medicine, lung-moistening herbal medicines (LMHM) are regarded as a major option for treating symptoms of pulmonary fibrosis (PF) including dry cough and dyspnea. As PF agents are being applied to the development of lung cancer agents, PF and lung cancer are reported to have high pathological and pharmacological relationships. This study was proposed to identify candidates for the treatment of PF via investigating the effect of LMHM on PF mouse model. PF was induced by intratracheal instillation of bleomycin. Six water extracts of LMHM such as Farfarae Flos (FAF), Trichosanthis Semen (TRS), Lilii Bulbus (LIB), Adenophorae Radix (ADR), Asteris Radix (ASR), and Scrophulariae Radix (SCR) were prepared and administered (300 mg/kg) orally for 10 days after induction. The changes in body weight, histopathology, and immune cell of bronchoalveolar lavage fluid (BALF) were investigated. Among those, LIB and ADR significantly decreased the deposition of collagen and septal thickness of alveolar and terminal bronchiole. Moreover, SCR, TRS, LIB, and ADR decreased total cells, macrophages, and lymphocytes in BALF. Taken together, ADR and LIB could be the candidates to reduce PF. Further studies on their effects at different doses and analysis of their underlying molecular mechanisms are needed.

Background: Treatment for interstitial pneumonia (IP) associated with collagen diseases has not been established. There is a need to elucidate the pathogenesis of IP and develop a novel therapy. We aimed to clarify the role of chemokine (C-X3-C motif) ligand 1 (CX3CL1, also known as fractalkine) in IP. Methods: Bleomycin (BLM) was intratracheally administered to C57BL/6 mice to induce IP. For treatment with control Ab or anti-CX3CL1 mAb, the mice were administered either Ab three times per week for 2 weeks from the day of BLM administration until euthanasia. Expressions of CX3CL1 and its unique receptor CX3CR1 in the lung tissue were examined by immunohistochemical analysis. Cellular infiltration and lung fibrosis were evaluated based on hematoxylin-eosin-staining and Sirius red staining of the lung tissue sections, respectively. Bronchoalveolar lavage fluid (BALF) cells were analyzed by flow cytometry. Results: CX3CL1 and CX3CR1 were strongly expressed in the lung tissue from mice with BLM-induced IP (BLM-IP). Treatment with anti-CX3CL1 mAb did not significantly alter inflammatory cell infiltration or fibrosis in the lung tissue. However, the number of M1-like macrophages in BALF was decreased and surface CD3 expression on T cells was increased by anti-CX3CL1 mAb treatment. Conclusions: Inhibition of CX3CL1 decreased inflammatory cells and may attenuate T cell activation in BALF. CX3CL1 inhibitor may have the potential to suppress the infiltration and activation of immune cells in IP.

BACKGROUND: The Passion Fruit (Passiflora sp.) that grows in the Indonesian region generally has three varieties, namely purple passion fruit (Passiflora edulis Sims.), red passion fruit (Passiflora ligularis Juss.), and yellow passion fruit (Passiflora verrucifera Lindl.). The passion fruit peel is an economic waste that has not been utilised optimally, but has many efficacious phytochemical contents. AIM: The objectives of this research are to examine scientifically hepatoprotective activity (with paracetamol-induced hepatotoxic) and nephroprotective activity (with gentamicin-induced nephrotoxic) from three varieties of the passion fruit (purple passion fruit peel extract, red passion fruit peel extract and yellow passion fruit peel extract) in the albino rat (Rattus norvegicus). METHODS: Three varieties of passion fruit peels were extracted by maceration method. The experimental animals used were the albino rat (Rattus norvegicus). Hepatoprotective activity was done by the liver biochemical (alanine transaminase and aspartate transaminase) analysis with paracetamol (hepatotoxic compound) induced after 10 days of treatment with extract. Nephroprotective activity was done by the kidney biochemical (urea and creatinine) analysis with gentamicin (nephrotoxic compound) induced after 10 days of treatment with extract. RESULTS: The hepatoprotective activity for positive control was similar to the 250 mg of purple passion fruit peel extract per kg of body weight, 250 mg of red passion fruit peel extract per kg of body weight, and 500 mg of yellow passion fruit peel extract per kg of body weight. The nephroprotective activity for positive control (50 mg of silymarin per kg of body weight) was similar to the 250 mg of purple passion fruit peel extract per kg of body weight, 500 mg of red passion fruit peel extract per kg of body weight, and 500 mg of yellow passion fruit peel extract per kg of body weight. CONCLUSIONS: The extracts were shown hepatoprotective activity and nephroprotective activity with a dose-dependent activity. The hepatoprotective activity and nephroprotective activity of purple passion fruit peel extract were the best compared to red passion fruit peel extract and yellow passion fruit peel extract.

Therapeutic Mechanism

The present study aimed to investigate the therapeutic effect of monoammonium glycyrrhizinate (MAG) on lipopolysaccharide- (LPS-) induced acute lung injury (ALI) in mice and possible mechanism. Acute lung injury was induced in BALB/c mice by intratracheal instillation of LPS, and MAG was injected intraperitoneally 1 h prior to LPS administration. After ALI, the histopathology of lungs, lung wet/dry weight ratio, protein concentration, and inflammatory cells in the bronchoalveolar lavage fluid (BALF) were determined. The levels of tumor necrosis factor-α(TNF-α) and interleukin-1β(IL-1β) in the BALF were measured by ELISA. The activation of NF-κB p65 and IκB-αof lung homogenate was detected by Western blot. Pretreatment with MAG attenuated lung histopathological damage induced by LPS and decreased lung wet/dry weight ratio and the concentrations of protein in BALF. At the same time, MAG reduced the number of inflammatory cells in lung and inhibited the production of TNF-αand IL-1βin BALF. Furthermore, we demonstrated that MAG suppressed activation of NF-κB signaling pathway induced by LPS in lung. The results suggested that the therapeutic mechanism of MAG on ALI may be attributed to the inhibition of NF-κB signaling pathway. Monoammonium glycyrrhizinate may be a potential therapeutic reagent for ALI.

The present study aimed to examine the antioxidant properties of Houttuynia cordata (HC) and its protective effect on bleomycin-induced pulmonary fibrosis in rats. Results showed that aqueous extract of HC exhibited a different magnitude of antioxidant activities in all model systems tested. Although HC showed weaker free radical scavenging and xanthine oxidase inhibitory activity than vitamin E, its anti-lipid peroxidation activity in rat liver homogenate was close to that of vitamin E. In animal studies, HC significantly decreased the levels of superoxide dismutase, malondialdehyde, hydroxyproline, interferon-γ, and tumor necrosis factor-α. However, an increase in the concentration of catalase was noted in the bronchoalveolar lavage fluid. HC also remarkably improved the morphological appearance of the lung of bleomycin-treated rats. These results suggest that HC possesses a protective effect against bleomycin-induced pulmonary fibrosis. Interestingly, this protective effect was more pronounced than that of vitamin E. In conclusion, the protective effect of HC on pulmonary fibrosis could be partly associated with the reduction of oxidative damage caused by bleomycin.

In current research, the synthesis of gold nanoparticles was achieved via reducing of gold ions in aqueous solution with Garcinia mangostana (G. mangostana) peel extract. The optimum concentration of gold (Au) solution, concentration ratio of Au solution and extract, temperature, time and pH, the synthesized AuNPs (G. mangostana-gold nanoparticles) were studied by using UV-Vis, FT-IR, AAS, AFM, SEM and Zitasizer. The absorbance peak is noticed between 535-550 nm via UV-Vis spectroscopic method. The SEM, AFM analysis were proofed the particle as spherical in structure and their size between 15-100nm. Therefore, mechanism of AuNPs synthesis had been suggested. Also, the antibacterial activity was examined using different bacteria as well as free radical scavenging activity was tested using 1, 1-Diphenyl-2-picrylhydrazyl (DPPH). The AuNPs produced through biosynthesized method indicated a much elevated antioxidant activity as compared to peel extract of G. mangostana. Toxicity of the NPs and extract were tested via giving orally dose 50 mg/b.w. to mice. Diagnosis of the data (pathological changes) indicated that the AuNPs was non-toxic. The G. mangostana peel extract and AuNPs synthesized by this extract were converted to a cream and used as a wound healing cream. As a results, the AuNPs exhibited important role in wound healing progression compared to control, which may be attributed to their anti-inflammatory, antibacterial and antioxidant activities. Therefore, this research confirms its important use of AuNPs and can be utilized as promising agents for in the development of new drugs.

Epidemiological studies have indicated that obesity is an independent risk factor for colitis and that a high-fat diet (HFD) increases the deterioration of colitis-related indicators in mice. Melatonin has multiple anti-inflammatory effects, including inhibiting tumor growth and regulating immune defense. However, the mechanism of its activity in ameliorating obesity-promoted colitis is still unclear. This study explored the possibility that melatonin has beneficial functions in HFD-induced dextran sodium sulfate (DSS)-induced colitis in mice. Here, we revealed that HFD-promoted obesity accelerated DSS-induced colitis, while melatonin intervention improved colitis. Melatonin significantly alleviated inflammation by increasing anti-inflammatory cytokine release and reducing the levels of proinflammatory cytokines in HFD- and DSS-treated mice. Furthermore, melatonin expressed antioxidant activities and reversed intestinal barrier integrity, resulting in improved colitis in DSS-treated obese mice. We also found that melatonin could reduce the ability of inflammatory cells to utilize fatty acids and decrease the growth-promoting effect of lipids by inhibiting autophagy. Taken together, our study indicates that the inhibitory effect of melatonin on autophagy weakens the lipid-mediated prosurvival advantage, which suggests that melatonin-targeted autophagy may provide an opportunity to prevent colitis in obese individuals.

Pleurotus eryngii(P. eryngii) is consumed as a fresh cultivated mushroom worldwide and demonstrated to have multiple beneficial effects. We investigated the anti-inflammatory effect ofP. eryngiiin mice with acute lung injury (ALI). Intranasal instillation of lipopolysaccharide (LPS) (10 μg/site/mouse) induced marked lung inflammation (increase in the number of inflammatory cells, protein leakage, and production of nitric oxide in bronchoalveolar lavage fluid) as well as histopathological damage in the lung, 6 h after treatment. Mice administered heat-treatedP. eryngii(0.3–1 g/kg, p.o. (HTPE)) 1 h before LPS challenge showed decreased pulmonary inflammation and ameliorated histopathological damage. These results suggest that HTPE has anti-inflammatory effects against ALI. Thus,P. eryngiiitself may also have anti-inflammatory effects and could be a beneficial food for the prevention of ALI induced by bacterial infection.
