OBJECTIVE Trichlorethylene (TCE) is one of the most potent organic unsaturated solvents being used in dry cleaning, metal degreasing, thinner for paints varnishes and electroplating, etc. and has been reported to be a hepatoxicant through oral and dermal exposure. However, its inhalation toxicity data is very limited in the literature due to the fact that(More)
Trichloroethylene (TCE) is an organic solvent used in dry cleaning, metal degreasing, thinner for paints and varnishes, anesthetic agent, and so forth. Human beings are appreciably exposed to TCE vapours by inhalation route. The present study has been undertaken to investigate whether TCE inhalation may also bring about testicular toxic effects.

In epidemiological studies, biomass fuel smoke has been reported to be responsible for several respiratory disorders in exposed population. In a laboratory(More)
Effect of respirable fly ash particles inhalation on lungs of rats was investigated by exposing them to respirable aerosols of size classified power plant fly ash at average concentrations of up to 14.4 +/- 1.77 mg/m3 for 4 hr/day for 28 consecutive days. A remarkable increase was found in blood eosinophil counts of fly ash exposed animals. Biochemical(More)
OBJECTIVE The pulmonary toxicity of a commercially available formulated preparation of Fenvalerate (Fen), a synthetic pyrethroid has been studied in rats following subchronic nose only inhalation exposure route. METHOD Adult male rats were exposed to Fen for 4 h/day, 5 days a week for 90 days by using Flow Past Dynamic Nose only Inhalation Chamber. (More)
OBJECTIVE Fenvalerate (20% EC) is a synthetic pyrethroid, which is commonly used in India by farmers for the protection of many food and vegetable crops against a wide variety of insects. However, its inhalation toxicity data is very limited in the literature due to the fact that the exposure levels associated with these effects were usually not reported.(More)
OBJECTIVE To investigate the pharmacological effect of Nyctanthes arbortristis (NAT) leaf extract in the prevention of lung injury induced by silica particles. METHOD Lung injury was induced in Swiss mice through inhalation exposure to silica particles (< 5 mu) using a Flow Past Nose Only Inhalation Chamber at the rate of -10 mg/m3 respirable mass for 5(More)
