BACKGROUND Nitrite (NO2) is a physiologic source of nitric oxide and protects against ischemia-reperfusion injuries. We hypothesized that nitrite would be protective in a rat model of ventilator-induced lung injury and sought to determine if nitrite protection is mediated by enzymic catalytic reduction to nitric oxide. METHODS Rats were anesthetized and mechanically ventilated. Group 1 had lo...
BACKGROUND Porphyra tenera (Kjellman, 1897) is the most common eatable red seaweed in Asia. In the present study, P. tenera volatile oil (PTVO) was extracted from dried P. tenera sheets that were used as food by the microwave hydrodistillation procedure, after which the characterization of its chemical constituents was done by gas chromatography and mass spectroscopy and its antioxidant potenti...
Sepsis is a systemic inflammatory response syndrome in the presence of suspected or proven infection, and it may progress to or encompass organ failure (severe sepsis) and hypotension (septic shock). Clinicians possess an arsenal of supportive measures to combat severe sepsis and septic shock, and some success, albeit controversial, has been achieved by using low doses of corticosteroids or rec...
methanolic and aqueous extracts of dendrophthoe falcata linn. leaves which belongs to the loranthaceae family, were evaluated through dpph (1, 1-diphenyl -2-picryl-hydrazyl), antilipid peroxidation and nitric oxide scavenging methods to assess the antioxidant activity. methanolic and aqueous extracts of dendrophthoe falcata leaves were also evaluated for their anti-inflammatory activity by carr...
background & aim:oxidative stresses caused by free radicals are known to promote many diseases such as inflammation and cancer; therefore, any plant product that can inhibit free radical production can play an important role in preventing diseases. we aimed to compare the fracture rate and the scavenging activity of free radicals, and the antioxidant composition of rolb-transformed hairy root o...
Effects of Fe-chlorophyllin on the growth of wheat root were investigated in this study. We found that Fe-chlorophyllin can promote root growth. The production of nitric oxide in wheat root was detected using DAF-2DA fluorescent emission. The intensity of fluorescent in the presence of 0.1 mg/L Fe-chlorophyllin was near to that observed with the positive control of sodium nitroprusside (SNP), t...
Tinospora cordifolia (Willd.), belonging to the family Menispermaceae, is known to exhibit a wide array of pharmacological properties such as antiulcer, anti-inflammatory and antiarthritic properties. In the present study an attempt has been made to evaluate the antioxidant and glucose uptake potential of T. cordifolia leaves extract in vitro. Phytochemical analysis of the leaves extract reveal...
BACKGROUND Many diseases are associated with oxidative stress caused by free radicals. Current research is directed towards finding naturally-occurring antioxidants of plant origin. The aim of the present study was to evaluate the in vitro antioxidant activities of Spondias pinnata stem bark extract. METHODS A 70% methanol extract of Spondias pinnata stem bark was studied in vitro for total a...
