Antibacterial  & antiinflamatory, ... As displayed in Figure 1, only the extracts from P. granatum and P. guajava leaves were shown to markedly inhibited LPS-induced NO production as compared with the LPS-treated group. P. guajava leaf was also shown to have suppressed the expression and activity of both iNOS and COX-2 through the downregulation of ERK1/2 activation. Grip O, Janciauskiene S, Lindgren S: Macrophages in inﬂam-, and inhibited the production of IL-6 and TNF-, survival curves was signiﬁcant, as calculated by log-rank test, Values with different letters are signiﬁ-, cantly different compared to treatment with LPS alone (, ygenase-2 expression in lipopolysaccharide-stimulated mouse, survival. Ligation caused a significant, more than 3 fold increase in the gingival iNOS activity, whereas it did not affect iNOS activity on the contralateral side, when compared to sham-operated animals. (B) RAW264.7 cells were pretreated with different concentrations of GLE for 2 h, and then stimulated with LPS (1 lg/mL) for another 22 h. Cell lysates were obtained, and iNOS protein levels were analyzed via Western blotting. The plant produces milky latex that possesses potent antiinflammatory and analgesic properties. MATERIALS AND METHODS The matured leaves of Psidium guajava were washed under running tap water and dust was removed from the leaves. The same membranes were reblotted with anti-p38, anti-ERK, and anti-JNK antibodies. Studium Press, Houston, 2008, C: Alterations in nitric oxide production in various forms. The consumption of local green leafy vegetables, fruits and leguminous crops as well as seaweeds and sea cucumbers need to be better promoted and their use encouraged. There is scope for further research on optimum production and postharvest handling systems to retain the health benefit (bioactive properties) and nutritional value and to enhance the agribusiness and market potential. Effects of GLE on activation of (A) ERK, JNK, and p38 and (B) IjB-a and translocation of p65 in LPS-stimulated RAW264.7 cells. Kubes P, McCafferty DM: Nitric oxide and intestinal inﬂam-, 30. 29. GLE, guava leaf extract; LPS, lipopolysaccharide; NO, nitric oxide; iNOS, inducible nitric oxide synthase. e guava leaves were extracted using a Soxhlet extractor and solvents in order of polarity and then concentrated in a rotary evaporator. AMP-activated protein kinase (AMPK) activity of compounds obtained from leaves of Psidium guajava was evaluated in L6 rat myoblast cells and L02 human hepatic cells by western blot. GLE suppressed the expression and activity of both inducible nitric oxide synthase and cyclooxygenase-2 in part by the downregulation of ERK1/2 (extracellular signal-regulated kinase-1) activation in RAW 264.7 macrophages, ... Flavonoids are frequently present in vegetables and fruits and the consumption of flavonoids-rich diet is accepted to be beneficial against metabolic diseases including obesity, diabetic mellitus, and insulin resistance [17,18]. Simultaneous Analysis of Ursolic Acid and Oleanolic Acid in Guava Leaves Using QuEChERS-Based Extraction Followed by High-Performance Liquid Chromatography. GAPDH levels were measured as a control for the cDNA content of each sample. A number of herbal products are in use for their immunosuppressive effects. A scratch wound healing assay investigated the effects of guava on cell migration. The results shown are represen-. Sixty subjects (n = 20) in compliance with the inclusion criteria were randomly assigned to one of the 3 study groups i.e. GLE inhibits NO production by suppressing iNOS, expression in LPS-stimulated RAW264.7 cells, The effects of GLE on LPS-induced NO production in, RAW264.7 cells were investigated by measuring the, amount of nitrite released into the culture medium using the, Griess reaction. Conclusions: 2C). Cells were treated with lipopolysaccharides (LPS, 1μg/mL) and guava to assess inflammatory gene expression levels of interleukin-β1, tumor necrosis factor-α, and Prostaglandin E2. Copyright © 2011 John Wiley & Sons, Ltd. Thuja orientalis (TO) has been a recognized herbal medicine across Northeast Asian countries for thousands of years and used for the treatment of various inflammatory diseases through as yet undefined mechanisms. Filter residues were extracted with 100 mL of distilled water (1:10 w/v) in an AS20500ATH ultrasonic cleaner bath (Tianjin Automatic Science Instrument Co., Ltd., China). Introduction: People living with HIV/AIDS (PLHIV) widely use medicinal plants for boosting immunity and managing infections.
