FIG. 3.

Representative GI tracts from SP-A null and wild type (WT) mice born and reared in the corn dust environment. The mouse on the left died after 8.5 h of life, while the other animals were euthanized after 24 h of life. An asterisk indicates the stomach, and an arrow indicates the site of the proximal intestine leaving the stomach. The stomach of the wild-type mouse is full of white milk, while the stomachs of the SP-A null mice contain little milk and their proximal intestines are bile colored.
