Jackson, Robert W. (University of California, San Diego, La Jolla), and J. A. DeMoss. Effects of toluene on Escherichia coli. J. Bacteriol. 90:1420-1425. 1965.-When toluene is added at appropriate levels to exponentially growing cultures of Escherichia coli, a time-dependent loss of turbidity is observed which is concurrent with a loss of material to the medium and with unmasking of beta-galact...

The degradation of trichloroethylene (TCE) by toluene-oxidizing bacteria has been extensively studied, and yet the influence of environmental conditions and physiological characteristics of individual strains has received little attention. To consider these effects, the levels of TCE degradation by strains distinguishable on the basis of toluene and nitrate metabolism were compared under aerobi...

This research aimed to investigate the protective effect of p-CA, a derivative phenolic acid, against toluene-induced oxidative damage. A total 32 Sprague-Dawley male rats, 8 in each group, were used. 4 groups formed as control, toluene, p-CA and toluene+p-CA. Animals control toluene group given 0.9 % NaCl, mg kg-1 b.w 100 orally for 21 days, respectively. The animals toluene+p-CA received 3 da...

Acute exposure to high doses of toluene can generate respiratory depression. However, neurotoxic mechanism of its action in the brainstem is not completely clear. In this work, acute, but not subchronic, exposure of rats to toluene increased leu-enkephalin immunostaining in several myelencephalic nuclei implicated in cardiorespiratory control. Due to the physiological role of enkephalins in the...

The present study was designed to determine the critical concentrations in blood and brain associated with specific behavioural changes during and after exposure to toluene. The effects of a single four hour exposure to toluene on signalled bar press shock avoidance in rats were tested. Rats exposed to 125, 250, and 500 ppm toluene showed a decline in conditioned avoidance responses at 20 minut...

Background: There is unprecedented increase in the processing and packaging of many plant materials into food supplements, herbal medicine, skincare and cosmetic products for human needs. Baphia nitida is used for topical skincare products. Toluene, a toxic aromatic solvent, is increasingly being used in the production of these skincare and cosmetic products in many industries. This study ass...

The patterns of use and related harm of solvent inhalation were investigated in a group of young people who misused toluene (n = 31) and a group misusing butane (n = 12). The two groups were similar in terms of patterns of use and solvent related harm. The toluene users were more likely to sniff only in a group setting, probably because of the long duration of intoxication. The toluene group we...

background: toluene is a volatile organic compound, one of 189 hazardous air pollutants (hap s ) and the most important pollutant found in most industries and indoor environments; owing to its adverse health, toluene must be treated before being released into the environment. methods : in this research study, a continuous-flow system (including an air compressor, silica gel filters and activate...
