Ogata, M., Yoshiko, T., and Tomokuni, K. (1971). Brit. J. industr. Med., 28, 386-391. Excretion of organic chlorine compounds in the urine of persons exposed to vapours of trichloroethylene and tetrachloroethylene. Male volunteers were exposed to 170 p.p.m. of trichloroethylene vapour either for 3 hours or for 7 hours with one break of 1 hour; or to 87 p.p.m. of tetrachloroethylene vapour for 3...

the effects of trichloroacetic acid/methylene chloride (tcac/mc) on the mechanical properties and solvent texturing of polyester yarns are studied. the treatments are carried out in unstrained and strained states at different concentrations of tcac for various treatment times. breaking load and elongation-at-break of treated yarns have been recorded. treatments of polyester yarns with tcac/mc i...

Extracts of etiolated pea (Pisum sativum L.) shoots converted soluble pectin from the seedlings to a trichloroacetic acid-insoluble form. This activity coincided with pectinesterase peaks separated from the extracts by gel filtration and ion exchange. The conversion of pectin to the trichloroacetic acid-insoluble form and pectinesterase exhibited identical responses to pH, with activity only ab...

Ikeda, M., and Ohtsuji, H. (1969). Brit. J. industr. Med., 26, 162-164. Hippuric acid, phenol, and trichloroacetic acid levels in the urine of Japanese subjects with no known exposure to organic solvents. Urine samples from 36 male and 30 female university students and 31 male factory workers with no known exposure to industrial organic solvents were analysed for hippuric acid, phenol, and tric...

The separation of liver ribonucleic acid and deoxyribonucleic acid from the associated protein material without hydrolysis can be accomplished by a salt-extraction procedure described by Barnum & Huseby (1950). This method, based on ribose recovery (Lowe & Rand, 1956; C. U. Lowe & P. R. Venkataraman, in preparation), yields 80% of the total ribonucleic acid of normal liver homogenate or cell fr...
