Bronchial artery ligation modifies pulmonary edema after exposure to smoke with acrolein.

Pulmonary edema can follow smoke inhalation and is believed to be due to the multiple chemical toxins in smoke, not the heat. We have developed a synthetic smoke composed of aerosolized charcoal particles to which one toxin at a time can be added to determine whether it produces pulmonary edema. Acrolein, a common component of smoke, when added to the synthetic smoke, produced a delayed-onset pulmonary edema in dogs in which the extravascular lung water (EVLW) as detected by a double-indicator technique began to rise after 42 +/- 2 (SE) min from 148 +/- 16 to 376 +/- 60 ml at 165 min after smoke exposure.

Synthetic smoke with acrolein but not HCl produces pulmonary edema.

The chemical toxins in smoke and not the heat are responsible for the pulmonary edema of smoke inhalation. We developed a synthetic smoke composed of carbon particles (mean diameter of 4.3 microns) to which toxins known to be in smoke, such as HCl or acrolein, could be added one at a time.

Nutrition and its importance in dental health.

Balanced and good nutrition is necessary for the growth, development, and maintenance of the dental and oral structures. Nutrition counseling is, therefore, of paramount importance. The physician who is aware of the factors that cause dental and oral disease will be in a position to intercept the progress of dental caries caused by an incorrect diet.
