Polycyclic aromatic hydrocarbons (PAHs) are products of incomplete combustion that are commonly inhaled by workers in the dusty trades. Many PAHs are metabolized by cytochrome P-4501A1 (CYP1A1), which may facilitate excretion but may activate pulmona

Amiodarone (AD) is gaining support as a first-line antiarrhythmic drug despite its potentially fatal pulmonary toxicity involving inflammation and fibrosis. The goals of this study were to characterize a rat model of AD-induced pulmonary toxicity (AI

We have reported previously that grinding crystalline silica generates radicals on its cleavage planes and that this fresh dust is more cytotoxic in vitro than aged silica. The objective of the present study was to determine if freshly fractured sili

Because some evidence indicates that there is an increased incidence of lung cancer in silicosis, we studied the effects of exposing rats to silica on the pulmonary microsomal cytochrome P-450 system. Rats were exposed to silica by intratracheal admi

Tetrandrine (TT) and other bisbenzylisoquinoline alkaloids have been used in China as a treatment for fibrotic lung diseases. Because of their potential use as pulmonary therapeutic agents, we studied the effects of some of these compounds on energy

Previous studies have shown that vitamin E may be an integral part of lung surfactant and may function to protect this material from oxidant damage. Therefore, we measured the vitamin E levels in alveolar lavage materials from rats exposed to crystal

Although lethal exposures of most animal species to oxygen result in a reduced amount of surfactant phospholipids (PL), hyperoxia in rats leads to elevated levels of PL on the alveolar surface. Because of this different response, a study was made of

Because some evidence suggests that there may be an increased incidence of lung cancer in silicosis and because previous studies have shown that exposure of rats to silica alters the pulmonary cytochrome P-450 system, we studied the effects of exposi

The cell volume, cell water, intracellular ionic concentrations, and transmembrane potential of rat alveolar macrophages were determined. The measurements were made on cells which had been separated from the medium by centrifugation through dibutyl p

The in vitro effects of Cd, Zn, and Pb on pulmonary, adrenal, and hepatic microsomal enzyme activities in guinea pigs were compared. Cd and Zn produced concentration-dependent (20-200 microM) decreases in benzphetamine demethylase and biphenyl hydrox
