The effect of several antifoaming agents by inhalation in preventing paroxysmal pulmonary edema was tested in a series of rabbits. Three single agents (silicone aerosol, freon, and ethyl alcohol vapor) proved beneficial; their combination did not enhance the beneficial effect. A new agent (silicone aerosol) and a new combination (10 per cent ether in alcohol by aerosol) are now ready for clinic...

A natural dye lawsone (2-hydroxy-1, 4-naphthoquinone) was isolated from dry leaves of Lawsonia inermis L., by extraction with clove oil, ethyl alcohol, water and its effectiveness as staining agent for angiospermic stem tissue was studied. Lawsonia revealed meta-chromatic property of staining. A 10%w/v crude extract of Lawsonia inermis L., leaves in ethyl alcohol and water were used for stainin...

We investigated whether presenting of dilutions of phenyl ethyl alcohol at random succession according to the method of constant stimuli can replace the standard procedure of presenting a various number of dilutions in a staircase paradigm. Forty-six men and 44 women, aged 19-76 years, participated in this study. Phenyl ethyl alcohol was diluted in a ratio of 1:2, starting from 4%. Presentation...

The effect of high inspired carbon dioxide concentrations and i.v. ethyl alcohol on the temperature at which cardiac arrest occurred was studied in chacma baboons. Alcohol-treated baboons developed cardiac arrest at a temperature of 24.3 degrees C (SD +/- 0.85) and control animals at 27 degrees C (SD +/- 1.30). There were no signs of cardiac failure before the occurrence of ventricular fibrilla...

A highly efficient, two-step sequence method for the deoxygenation of hydroxyl groups has been developed. The method involves the preparation of the 2-(2-iodophenyl)ethyl methyl phosphite derivative of an alcohol using methyl dichlorophosphite and 2-(2-iodophenyl)ethanol. Treatment of the phosphite intermediate with (n-Bu)3SnH/AIBN in refluxing benzene cleanly produces the deoxygenation product...

Hexi Corridor is an excellent region for high-quality wines in China, but the characteristic and style of red wine from this unclear. To elucidate regional Corridor, aroma properties made 16 different varieties/clones grapes were comprehensively analyzed using HS-SPME-GC-MS, sensory evaluation, odor activity value method, partial least squares regression analyses. We identified 52 compounds fou...

A nitrogen deficiency always causes bog bilberry syrup wine to have a poor sensory feature. This study investigated the effect of nitrogen source addition on volatile compounds during bog bilberry syrup wine fermentation. The syrup was supplemented with 60, 90, 120 or 150 mg/L dibasic ammonium phosphate (DAP) before fermentation. Results showed that an increase of DAP amounts accelerated fermen...
