BACKGROUND: The aim of this study is to control the depth, the quality of recovery of total inhalation isoflurane anesthesia with or without nitrous oxide. DESIGN: Controlled comparative study was carried out on 51 patients, aged 40-54 yr, ASA 1, undergoing saphenectomy, in an University Clinic. METHODS: Induction: thiopental (3.5 mg kg), atracurium (0.6 mg kg) i.v. Patients were randomly assigned to: group 1 (26 patients), 5% isoflurane in air, by mask; group 2 (25 patients), 3% isoflurane and 60% N2O, by mask.

Traditional Chinese medicine relies heavily on herbs, yet there is no information on how these herb plants would respond to climate change. In order to gain insight into such response, we studied the effect of elevated [CO2] on Isatis indigotica Fort, one of the most popular Chinese herb plants. The changes in leaf photosynthesis, chlorophyll fluorescence, leaf ultrastructure and biomass yield in response to elevated [CO2] (550±19 µmol mol(-1)) were determined at the Free-Air Carbon dioxide Enrichment (FACE) experimental facility in North China. Photosynthetic ability of I.

In this paper, soil respiration chamber, a simple and precise method, was used to measure the stem respiration of trees. LI-6400-09 respiration chamber serving as a system is usually used in soil respiration, but we made polyvinyl chloride (PVC) collar and fixed it on the stem surface to measure the stem respiration. From May to October 2003, the stem respiration of Pinus koraiensis, the dominant tree species in Changbai Mountain, was measured in different time and different places using this technique. Meanwhile, the temperatures in the stems and in the forests were measured.

OBJECTIVE: The objective of this 16-week, double-blind, randomized, switch-over design study was to compare the efficacy in reducing dentin hypersensitivity of a dentifrice containing 8.0% arginine, calcium carbonate, and 1450 ppm fluoride as sodium monofluorophosphate (Colgate Sensitive Pro-Relief [also marketed as elmex Sensitive Professional]) to a desensitizing dentifrice containing 8% strontium acetate and 1040 ppm fluoride as sodium fluoride (Sensodyne Rapid Relief) under relevant consumer usage conditions.

BACKGROUND: The aim of the present study is to evaluate the relative abilities of three desensitizing dentifrices to provide rapid relief of dentin hypersensitivity (DH). METHODS: Using a double-mask, randomized design, three dentifrices: 1) containing 8% arginine and 1,450 ppm sodium monofluorophosphate; 2) containing 8% strontium acetate and 1,040 ppm sodium fluoride; and 3) containing 30% microaggregation of zinc-carbonate hydroxyapatite nanocrystals were compared after 3-day treatment.

AIMS: A randomized clinical trail was designed to compare the efficacy of two commercially available desensitizing agents (fluoride varnish containing 6% sodium fluoride and 6% calcium fluoride and a gel containing 6% potassium nitrate and 0.11% fluoride ions) in the treatment of dentinal hypersensitivity. SETTINGS AND DESIGN: Randomized clinical trial. MATERIALS AND METHODS: Twenty-one patients were selected. Subjects were evaluated using three different stimuli, i.e., tactile test, air blast test and cold water test. They were then randomly divided into two groups.

PURPOSE: To compare the Jay Sensitivity Sensor Probe (Jay Probe), a new microprocessor-based, pre-calibrated instrument, with well accepted methods used to evaluate sensitivity, i.e. tactile response to the Yeaple Probe, air blast (Schiff scale), and patient responses by Visual Analog Score (VAS). METHODS: Jay Probe assessments were accomplished using several approaches. With a cohort of 12 subjects, two clinical examiners compared the repeatability of the Jay and Yeaple Probes.

PURPOSE: To compare a new tactile hypersensitivity testing device [Jay Sensitivity Sensor (Jay) Probe] to three currently available methods of hypersensitivity testing: tactile hypersensitivity by the Yeaple probe, air blast (Schiff's Scale), and their overall hypersensitivity in the absence of any stimuli using the visual analog scores (VAS) during a clinical trial comparing the desensitizing potential of a dentifrice containing 8% arginine, calcium carbonate, and 1,000 ppm MFP (Colgate Sensitive Pro-Relief; Test) against a commercially available fluoride dentifrice (Colgate Cibaca; N
