AbstractPolystyrene microspheres in the size range 50 nm to 3 μm were fed by gavage to female Sprague Dawley rats daily for 10 days at a dose of 1.25 mg kg−1. Previous histological evidence of the uptake of these particles and their absorption across the gastrointestinal tract and passage via the mesentery lymph supply and lymph nodes to the liver a...... hiện toàn bộ

AbstractNanosuspensions have emerged as a promising strategy for the efficient delivery of hydrophobic drugs because of their versatile features and unique advantages. Techniques such as media milling and high-pressure homogenization have been used commercially for producing nanosuspensions. Recently, the engineering of nanosuspensions employing emu...... hiện toàn bộ

AbstractThe chemical composition of St. John's wort has been well-studied. Documented pharmacological activities, including antidepressant, antiviral, and antibacterial effects, provide supporting evidence for several of the traditional uses stated for St John's wort. Many pharmacological activities appear to be attributable to hypericin and to the ...... hiện toàn bộ
AbstractSome pharmacological actions of curcumin (diferuloyl methane) have been examined in rats, mice and cats. The compound possesses significant anti-inflammatory activity in acute as well as in chronic models of inflammation. It is as potent as phenylbutazone in the carrageenan oedema test but only half as potent in chronic tests. Curcumin posse...... hiện toàn bộ

AbstractTo assess the variation in antibacterial activity of honey a survey was carried out on 345 samples of unpasteurized honey obtained from commercial apiarists throughout New Zealand. Most of the honeys were considered to be monofloral, from 26 different floral sources. The honeys were tested against Staphylococcus aureus in an agar well diffus...... hiện toàn bộ
AbstractAn in-vitro test system was developed to investigate the adhesiveness of various materials to mucus. The results obtained showed good agreement with the findings of previous in-vivo evaluations of mucosa-adhesives. Further investigations found that these materials become adhesive on hydration. Chain length, and the presence of ionizable grou...... hiện toàn bộ
