Several methods (e.g., UV/H2O2 oxidation, adsorption, flocculation-precipitation) are normally employed to remove dye from water. A new technique based on liquid/liquid extraction using reverse micelles is proposed whereby recovery of solvent and reuse of dye is possible. Experiments were conducted by mixing a known quantity of dye in aqueous phase and solvent-containing surfactants in a simple...
In hair beauty treatments such as permanent waving and hair coloring, and in daily treatments using shampoo and hair conditioner, most of the hair care products are used under wet conditions. Therefore, it is important to understand how water-soluble products penetrate into hair. The structural information of hair in aqueous solutions seems essential for understanding the penetration mechanism....
The anti-diarrheal activity of the alcohol and aqueous extracts of the roots of Dodonaea viscosa (Sapindaceae) was investigated by castor oil induced diarrhea in mice. The parameters of this study were number of diarrheal episodes and mean weight of stool of mice. The percentage protection in extract treated animals showing diarrhea was compared with castor oil treated and loperamide treated an...
A study was conducted to analyze the effects of propolis mouth rinse on the repair of surgical wounds after sulcoplasty by the modified Kazanjian technique. Twenty-seven patients who underwent sulcoplasty were divided into three groups: C1--patients who did not use the mouth rinse C2--patients who used a mouth rinse containing 5% aqueous alcohol T--patients who used a mouth rinse containing 5% ...
Vibrational sum frequency generation (VSFG) spectroscopy and molecular dynamics (MD) simulations are used to study the surface residence and organization of gas-phase methyl halide and methyl alcohol molecules adsorbed to the air/water interface, while Raman spectroscopy is used to detect the uptake of the gas-phase species into the bulk aqueous phase. Spectroscopy results reveal the presence o...
Evaluation of effect of the aqueous, alcohol and chloroform extract of Psoralea corylifolia on sexual behaviour of male albino rats. Plant extracts (aqueous, alcohol and chloroform) at doses of 100, 200 and 400 mg/kg were administrated for 21 days. The female rats involved in mating were made receptive by hormonal treatment. The general mating behaviour, libido and potency along with orientatio...
The effects of aqueous and deuterium oxide (D2O) solutions alcohols (methanol, ethanol, 1-propanol, 2-propanol, 1-butanol) on the thermomechanical properties poly(lactic acid)—PLA—films were assessed by dynamic mechanical analysis. glass transition temperature (Tg) PLA films immersed in 25%, 50%, 75%, 100% (v/v) alcoholic compared with Tg water D2O. methanol ethanol decreased as concentration a...
OBJECTIVES Aloe barbadensis miller or Aloe vera has been used for therapeutic purposes since ancient times with antifungal activity known to be amongst its medicinal properties. We conducted a pilot study to determine the antifungal properties of Malaysian Aloe vera leaf extract on otomycosis species including Aspergillus niger and Candida albicans. METHODS This laboratory-controlled prospect...
removing the bacteria, including enterococcus faecalis, from the root canal is one of the important aims in endodontic treatment.we aimed to compare the antibacterial activity of chlorhexidine with two natural drugs. the antibacterial activities of three different propolis extracts (alcohol concentrations: 0, 15, 40%) and aloe vera gel on e. faecalis were compared using three methods: disk diff...
