Hydroxychavicol isolated from the chloroform extraction of aqueous extract of Piper betle leaves showed inhibitory activity against oral cavity pathogens. It exhibited an inhibitory effect on all of the oral cavity pathogens tested (MICs of 62.5 to 500 microg/ml) with a minimal bactericidal concentration that was twofold greater than the inhibitory(More)
Decolorization of two monoazo dyes, acid orange 6 (AO6) and acid orange 7 (AO7), were studied in sequential fixed-film anaerobic batch reactor (SFABR) with varying dye concentrations and 500 mg/L glucose as the co-substrate. More than 90% dye decolorization could be achieved, even at 300 mg/L, with both AO6 and AO7 and dye decolorization rates were 168(More)
This study was taken up to see the effect of Withanolide A (WS-1), a compound isolated from Withania somnifera root extract on chronic stress-induced alterations on T lymphocyte subset distribution and corresponding cytokine secretion patterns in experimental Swiss albino mice. Stress disturbs the homeostatic state of the organism and brings about(More)
This study was carried out to investigate the protective effect of Hydroxychavicol (HC), a phenolic compound derived from Piper betel on experimentally induced Alzheimer's disease (AD) in rat. HC at graded doses administered orally once daily for a duration of 21 days significantly improved the cognitive impairment and attenuated the elevated levels of(More)
The purpose of this study was to elucidate the probable mechanism for the anti-arthritic activity of agnuside (AGN), a compound isolated from the leaf extract of Vitex negundo. The anti-inflammatory activity of AGN within a dose range of 1.56–12.50 mg/kg in normal and adrenalectomized rats was evaluated against different inflammagens. An array of(More)
The immunomodulatory activity of an Indian neutraceutical spice, saffron (Crocus sativus) was studied on Th(1) and Th(2) limbs of the immune system. Oral administration of alcoholic extract of Crocus sativus (ACS) at graded dose levels from 1.56-50 mg/kg p.o. potentiated the Th(2) response of humoral immunity causing the significant increases in(More)
Semi-synthetic analogs of pinitol were subjected to screening by determining TNF-alpha expression in human neutrophils using flowcytometry. Among the tested compounds, three derivatives displayed more than 50% inhibition of TNF-alpha cytokine secretion in LPS induced stimulated neutrophils and can be considered as potent anti-inflammatory moieties.
The objective of the study was to investigate the activity of Lupeol (LUP) on proinflammatory and anti-inflammatory cytokines in the pleural exudate from male swiss albino mice. We applied Cytometric bead array technology for simultaneously measurement of these cytokines in pleurisy induced mice treated with lupeol in graded oral doses. Cytometric bead(More)
The premise of the study was to investigate the antiarthritic potential of apocynin (APO) in Balb/c mice (in vivo). The experiment showed a dose-dependent decrease in oedema and showed a suppression of proinflammatory cytokines such as TNF-alpha and IL-1beta and mediators such as prostaglandin E(2) (PGE(2)) and LTB(4). At oral doses of 0.5, 1.0, 2.0 and 4.0(More)
The present study was undertaken to investigate the anti-arthritic activity of hydroxychavicol (HC) a major phenolic compound isolated from the aqueous extract leaves of plant Piper betle (Piperaceae). The compound showed significant lowering of pro-inflammatory (Th1) cytokine levels in arthritic paw tissue homogenate supernatant viz. IL-2, IFN-gamma, and(More)
