Comparative Anatomy Of The Lower Respiratory Tract Of The Gray Short-Tailed Opossum (Monodelphis Domestica) And North American Opossum (Didelphis Virginiana), Lee Anne Cope
Doctoral Dissertations
The present study describes the lower respiratory tract anatomy of the gray short-tailed opossum (Monodelphis domestica) and North American opossum (Didelphis virginiana). The trachea of the gray short-tailed opossum consists of 25 c-shaped tracheal cartilages. The trachea of the North American opossum consists of 28 c-shaped cartilages. The right lung of both species is separated into cranial, middle, caudal and accessory lobes by interlobar fissures. The left lung consists of unseparated cranial and caudal lobes. The right and left pulmonary arteries of the gray short-tailed and North American opossums divide into pulmonary lobar arteries. The pulmonary lobar veins join to …
Pathogenesis Of Acid Injury In The Non-Glandular Region Of The Equine Stomach: Implications In Gastric Ulcer Disease, Jenifer Ann Nadeau
Pathogenesis Of Acid Injury In The Non-Glandular Region Of The Equine Stomach: Implications In Gastric Ulcer Disease, Jenifer Ann Nadeau
Doctoral Dissertations
Forty-three horses were necropsied to determine if volatile fatty acids (VFAs)produced from fermentation of carbohydrates (acetic, butyric, propionic, and valeric acids) cause cellular injury which leads to gastric ulceration when exposed to the nonglandular mucosa of the stomach at pH 1.5, 4 and 7. In part I of the study thirty horses were necropsied to determine if acetic, butyric, or propionic acid could cause cellular injury. In part 2 of the study thirteen horses were necropsied to determine if acetic, butyric, propionic or valeric acid could cause cellular injury. In both studies the stomach was removed within one hour of …
