xylene/atrophy

Testicular and germ cell line morphology in rats were studied 2 weeks, 10 months and 14 months after cessation of a 61-day inhalation exposure to 1000 ppm n-hexane. Androgen biosynthetic capacity of testis, testosterone blood concentration, vas deferens morphology and noradrenaline (NA)

Male painters are commonly exposed to ethylene glycol monoethyl ether (EGE), a well known reproductive toxic agent causing testicular atrophy, in the form of solvent mixture containing toluene (TOL) and xylene (XYL). This study was carried out to determine the effect of exposing male rats to solvent

Occupational painters are exposed to ethylene glycol monoethyl ether (EGEE), a widely used emulsifying solvent known to cause testicular degeneration and bone marrow depression, together with toluene (TOL) and xylene (XYL) as a mixture. In the previous study (Chung et al., Tox. Lett. 104:143, 1999),

A 35-year-old man had prolonged occupational exposure to lead carboxylate, triethylbenzene, xylene, and dichloromethane, when he developed a subacute predominantly sensory neuropathy. Ultrastructural examination of a peripheral nerve biopsy showed axonal degeneration and unusual lesions of the

OBJECTIVE To report the case of an adult patient who developed auditory complaints following xylene exposure, and to review the literature on the effects of solvent exposure on hearing. METHODS The patient presented with a gradual deterioration in his ability to hear in difficult acoustic

This study investigates the use of electrically conductive granules as packing material in biotrickling filter (BTF) systems as to provide insights on the specific microbial abundance and functions during the treatment of xylene-containing waste gas. In addition, the effect of applied potential on

BACKGROUND Chronic exposure of BTX (benzene, toluene, xylene) may lead to progressive degeneration of bone marrow, aplastic anemia and/or leukemia. In Brazil there is no self-service fuel in gas stations and attendants fill the fuel themselves. Due to this they are chronically exposed to high

This study investigated the effects of sub-chronic administration of sub-lethal doses of amitraz on some testicular parameters of Albino rats. Twenty-four adult male Albino rats (100 ± 10 g) randomly assigned into four groups were used for the study. Groups A, B and C received 10.0, 2.0 and 0.4

The growth curve (increase in the number of viable cells) of a toluene-tolerant strain Pseudomonas putida Px51T was not reproducible in the presence of harmful organic solvents, such as p-xylene and toluene. The survival often fluctuated the during late exponential phase of growth. The repetitive

We have synthesized boron-incorporated carbon nanotubes (CNTs) by decomposition of ferrocene and xylene in a thermal chemical vapor deposition set up using boric acid as the boron source. Scanning and transmission electron microscopy studies of the synthesized CNT samples showed that there was

Effects of ozone on air sampling of standard gas mixtures of aromatic hydrocarbons were tested using solid-phase microextraction (SPME). Standard concentrations of ozone ranging from 10 ppb (v/v) to 6400 ppm (v/v) were generated using an in-house built ozone generator based on corona discharge.

Emissions from landfills are a significant source of non-methane volatile organic compounds (NMVOCs) in urban environments. NMVOCs play an important role in atmospheric chemistry, and elevated concentrations of some compounds are responsible for air quality deterioration. This study is based on the

As back diffusion gases from automobiles are significant sources of in-vehicular pollution, we investigated eight automobiles, five for back diffusion (driving) measurements and three for reference conditions (non-driving). To characterize the back diffusion emission conditions, seven volatile

OBJECTIVE The primary goal of this research was to assess the biodegradation of benzene, toluene, ethylbenzene and xylenes in sediment from Great Salt Lake, near Rozel Point, UT. RESULTS An enrichment culture that degraded benzene or toluene as the sole carbon source at high salinity was developed

Exposure of fish embryos to relatively low concentrations of oil has been implicated in sub-lethal toxicity. The objective of this study was to determine the effects of the exposure of Menidia beryllina embryos at 30-48h post-fertilization to the water accommodated fractions of oil (WAF, 200ppm,
