Pulmonary function changes in goats given 3-methylindole orally. 1984

J E Mesina, and G E Bisgard, and G M Robinson

Six adult goats were given 0.2 g of 3-methylindole (3MI)/kg of body weight orally. Lung mechanics and ventilatory function were obtained before 3MI and 2, 4, 6, 24, 48, and 72 hours after 3MI administration. Clinical signs were also monitored. Lungs were removed for gross and microscopic examination and for morphometric analysis from goats that died spontaneously or were killed with an overdose of pentobarbital after 72 hours. The major pulmonary function changes observed included a marked decrease in dynamic lung compliance with a moderate increase in airway resistance, a concomitant hypoxemia, sustained increase in respiratory frequency, a progressive decrease in tidal volume and alveolar ventilation, and increased dead space to tidal volume ratio. A mild metabolic acidosis was also noticed.

UI	MeSH Term	Description	Entries
D007211	Indoles	Benzopyrroles with the nitrogen at the number one carbon adjacent to the benzyl portion, in contrast to ISOINDOLES which have the nitrogen away from the six-membered ring.
D008168	Lung	Either of the pair of organs occupying the cavity of the thorax that effect the aeration of the blood.	Lungs
D008170	Lung Compliance	The capability of the LUNGS to distend under pressure as measured by pulmonary volume change per unit pressure change. While not a complete description of the pressure-volume properties of the lung, it is nevertheless useful in practice as a measure of the comparative stiffness of the lung.

D011654	Pulmonary Edema	Excessive accumulation of extravascular fluid in the lung, an indication of a serious underlying disease or disorder. Pulmonary edema prevents efficient PULMONARY GAS EXCHANGE in the PULMONARY ALVEOLI, and can be life-threatening.

D012119	Respiration	The act of breathing with the LUNGS, consisting of INHALATION, or the taking into the lungs of the ambient air, and of EXHALATION, or the expelling of the modified air which contains more CARBON DIOXIDE than the air taken in (Blakiston's Gould Medical Dictionary, 4th ed.).
