Dermal absorption of organic solvents, such as m-xylene, can lead to skin inflammation and pathological changes within hours after exposure. This study detected oxidative species formation and low molecular weight (LMW) DNA in rat skin as potential indicators of m-xylene-induced skin injury. At 0,
Exposure of the skin to volatile organic chemicals (VOCs) can lead to irritation, inflammation and cytotoxicity. Since VOCs are used in industrial, commercial and military applications, concern is mounting with respect to VOC safe exposure limits. Although traditional toxicological assessment of
OBJECTIVE
To evaluate possible differences between men and women in acute health effects after controlled short term chamber exposure to vapours of two common organic solvents.
METHODS
Fifty six healthy volunteers (28 per sex) were exposed to 150 ppm 2-propanol, 50 ppm m-xylene, and clean air for
In this study, the severity and time course of inflammation induced by 4 organic solvents (acetone, cyclohexane, toluene and m-xylene), and the effect of neuropeptides during the inflammation were investigated in the hairless rat abdominal skin. Plasma extravasation used as a parameter of
To investigate the relation between signs and symptoms of irritation and biomarkers of inflammatory markers in blood in healthy volunteers exposed to different chemical vapours for 2 or 4 hours in an exposure chamber.METHODS
The investigated chemicals
Tacrolimus ointment is used to treat various chronic inflammatory skin diseases. However, the effect of this ointment on acute neurogenic inflammation in the skin remains to be fully elucidated. Topical capsaicin and m-xylene produce tachykinin release from sensory nerves in the skin, resulting in
meta-Xylene (m-xylene) is one of three isomers of xylene, which is widely used as a solvent and detergent in various industries and medical technology. Exposure to volatile organic compounds, such as m-xylene, causes pulmonary inflammation and airway inflammation, thereby contributing to the onset
Pathomorphologic examinations of laboratory animals' respiratory system, carried out within evaluation of chemical substances toxicity, pose many diagnostic obstacles. Usually, pulmonary pathologies are evaluated based on arbitrarily adopted criteria and subjective "feelings" of a pathologist. To
Various volatile organic compounds (VOCs) act as a causative agent of skin inflammation. We investigated the effect of topical application of several VOCs and formalin on microvascular leakage in rat skin. We tested capsaicin, which is a reagent that specifically causes the skin response via
Many studies have established associations between exposure to air pollution, or atmospheric particulate matter (PM), and adverse health effects. An increasing array of studies have suggested oxidative stress as a possible mechanism by which PM-induced health effects arise, and as a Introduction: Many studies have established associations between exposure to air pollution, or atmospheric particulate matter (PM), and adverse health effects. An increasing array of studies have suggested oxidative stress as a possible
Increased indoor air concentrations of volatile organic compounds (VOC) have been shown to contribute to the risk of respiratory and allergic diseases. The aim of this study was to investigate the inflammatory potential of single VOC and mixtures using an in vitro model. TNF-alpha stimulated human
Cigarette smoke has always been considered as a risk factor for chronic obstructive pulmonary diseases (COPD). In this study, we have examined the effect of ten individual cigarette smoke compounds (nicotine, benzo[a]pyrene, naphthalene, formaldehyde, ammonia, acrylic acid, toluene, benzene,
Secondary organic aerosol (SOA) is a component of airborne particulate matter in urban areas. However, their toxicities remain incompletely understood. In this study, we investigated the oxidative and inflammatory potency of SOA derived from three different volatile organic compounds (α-pinene,
