This study was designed to investigate therapeutic effects of hyperbaric oxygen on experimentally induced colitis in rats by assessing oxidative tissue damage, neutrophil accumulation and histological changes. Six groups of animals were used. No procedures were done in the sham group. In the vehicle group, 50% ethanol-induced colitis, and in four other groups, 2,4,6-trinitrobenzene sulphonic ac...

As a by-product of wine making, pomace contains rich amounts of phenolic compounds that can be potentially utilized as raw materials to make beneficial products especially for the anti-cancer agents including the breast cancer. Muscadinia rotundifolia 'Noble' is a wine-making grape cultivar, and to better use 'Noble' pomace, the most effective phenolic fractions in cancer inhibition must be ide...

The effects of ketotifen, a 'mast cell stabiliser,' on two models of experimental colitis were examined. The inflammatory response elicited by either trinitrobenzene sulphonic acid or acetic acid resulted in increased colonic synthesis of platelet activating factor, prostaglandin E2, thromboxane B2, leukotrienes B4 and C4, and myeloperoxidase activity. Intragastric administration of ketotifen 1...

Picrorhiza kurroa is a well-known herb in Ayurvedic medicine. Although it shows antioxidant, antiinflammatory and immunomodulatory activities, it is most valued for its hepatoprotective effect. The rhizomes are widely used against indigestion problems since ancient times due to improper digestive secretions. Aim of this study was to explore antioxidant study of P. kurroa leaves for a new source...

The essential oils of the flowering aerial parts of two Ocimum species viz., Ocimum gratissimum and O. sanctum were analyzed by gas chromatography and gas chromatography/mass spectroscopy. The principal constituent of O. gratissimum and O. sanctum was eugenol (75.1%) and methyl eugenol (92.4%), comprising 99.3 and 98.9% of the total oils, respectively. In vitro antimicrobial activity of the ess...
