Randomized Controlled Trial Clinical TrialSynergetic analgesic effect of the combination of arnica and hydroxyethyl salicylate in ethanolic solution following cutaneous application by transcutaneous electrostimulation.
A combination of the active agents arnica and hydroxyethyl salicylate (HES) in ethanolic solution (Sportino Acute Spray) is cutaneously applied for the treatment of sports injuries and diseases of the locomotor apparatus. The aim was to examine the efficacy and synergism of the single substances and the combination with regard to the analgesic effect after cutaneous application as well as to validate the method of transcutaneous electronic stimulation as a method of measuring the analgesic effect. ⋯ In addition, the effect of the vehicle ethanol and the reference substance water could be determined within the framework of these comparative experiments and the difference between the combination preparation and the individual substances arnica and HES could be shown. The method of transcutaneous electrostimulation used for the objective measurement of the analgesic effect was validated.

Clinical TrialIncidence of pain after intravenous injection of a medium-/long-chain triglyceride emulsion of propofol. An observational study in 1375 patients.
To assess incidence and intensity of pain on intravenous injection of propofol (CAS 2078-548) in an emulsion of medium-chain/long-chain triglycerides (MCT/LCT, 50:50) in patients undergoing different elective surgical interventions. ⋯ The incidence of pain on injection of a medium-/long-chain triglyceride propofol formulation was 28.4% with 16.7% of the patients reporting mild pain. The use of an antecubital vein or a large size venous cannula appears to reduce the injection pain.

Synthesis and anticonvulsant activity of some new dioxolane derivatives.
In this study, ten 2-acetylnaphthalene derivatives with a dioxolane structure were synthesized and screened for their anticonvulsant activities. Dioxolane derivatives were prepared by the reaction with appropriate ethanone, glycol and p-toluensulphonic acid. The structures of the compounds were elucidated by IR, 1H-NMR and elemental analysis. ⋯ The rotarod toxicity test was used for the assessment of neurological deficits. According to the activity studies compound 6 was found neurotoxic, compounds, 1, 4, 5, 7-9 were found protective against MES and 7-10 were found protective against ScMet. Compounds 2 and 3 were found inactive.
