“…Bianco, Gibb, Kilpper, Landman and Morrow (1974) reported persisting islets of activity in the tracheobronchial (TB) region particularly at the tracheal bifurcation following tantalum insufflation. Both Antweiler (1956) and Hilding (1957) viewed the ciliary streaming of mucus in the bronchial tree and each reported a pattern which would tend to keep the carina free from particles. In the experiment now to be described delayed neutron analysis was used to determine accurately nanogram quantities of 235UOz particles in the region of the carina and on the trachea of rats up to 14 days after inhalation.…”

The distribution of inhaled UO2 particles is described in the upper respiratory tract of rats up to 14 d after inhalation. Delayed neutron analysis was used to determine accurately nanogram quantities of UO2 present in excised tissues. The mass of UO2 in the extrapulmonary bronchi and first bifurcation decreased more slowly over 0--8 d after inhalation than the corresponding mass on the trachea. Between 8 and 14 d neither amount altered significantly. Small but significant quantities of UO2 deposited on the trachea during inhalation, remained until at least 14 d after inhalation.

Relation of the Acute Pulmonary Response to Cotton Dust and Dust Compositional Analysis by Near-Infrared Reflectance Spectroscopy. Part I: Elutriated Dust

The near-infrared reflectance spectroscopy (NIRS) method of analysis, as applied to cotton dust, offers an independent method for searching for byssinosis causatives. We wish to report here a test of the hypothesis that the acute pulmonary response from subjects exposed to cotton dust is a linear function of the composition of elutriated dust as measured by near-infrared reflectance spectroscopy (NIRS). Indeed, a linear relationship was found between delta FEV1 (the forced expiratory volume in one second) and cotton dust captured by the vertical elutriator cotton dust sampler. Of the various agents proposed over the years as the byssinosis causative agent, at least three of them (gram-negative bacteria and their endotoxin, and tannins) were present in the dust at concentrations exceeding the NIRS sensitivity level, and may account for the observed relationship.

The near-infrared reflectance spectroscopy (NIRS) method of analysis, as applied to cotton dust, offers an independent method for searching for byssinosis causatives. We report here a test of the hypothesis that the acute pulmonary response from subjects exposed to cotton dust is a linear function of the composition of unsieved dust as measured by near-infrared reflectance spectroscopy (NIRS). A linear relationship was found between delta FEV1 (the forced expiratory volume in 1 second) and unsieved cotton dust captured by the Hi-Vol dust sampler. Of the various agents proposed over the years as the byssinosis causative agent, at least three of them (gram-negative bacteria and their endotoxins, and tannins) were present in the unsieved dust at concentrations exceeding the NIRS sensitivity level and may account for the observed relationship. No association was found between the pulmonary effects and cotton compositional analysis by NIRS. NIR reflectance spectra of cotton and cotton dust, in air and in nonabsorbing carbon tetrachloride, reveal similar absorption bands of different intensity.
