Abstract

Organic solvents are often present as mixtures in various industrial and house-hold products. The adverse effects arising from exposure to these solvents have often been generalized to concern the whole group of solvents. In an examination of the possibility that organic solvents have general effects on experimental animals, rats were continuously exposed to vapors of the halogenated solvents Freon 11, perchloroethylene, and 1,1,1-trichloroethane. The lipid composition and fatty-acid pattern of ethanolamine phosphoglyceride from the cerebral cortex were analyzed. It was observed that only perchloroethylene had effects on the brain lipid composition. Cholesterol and total phospholipids were slightly reduced. Among the fatty acids the proportion of stearic acid was reduced and those of docosapentanoic, 22:5 (N = 6), and of docosahexanoic, 22:6 (N = 3), acids were increased. The changes in the fatty-acid pattern indicate that an alteration occurs in the desaturation of fatty acids. It seems probable that the chloroethylenes have specific effects on the fatty-acid pattern of brain phospholipids not shared by other solvents.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
