چکیده
Within 3 hours of induction of acute hydrocephalus in a canine model, lateral ventricular CSF pressure increased from an initial average of 14.6 +/- 2.8 cm H2O to 40.2 +/- 5.7 cm H2O. Ventricular volumes, as measured from MR images, increased 1.45 +/- 0.94 cm3, 1.92 +/- 0.82 cm3, and 2.24 +/- 0.60 cm3 after 6, 24, and 48 hours, of hydrocephalus, respectively. This canine model was reliable and consistent with clinical conditions.

متن کاملUltrastructural evaluation of the acute encephalitis and hydrocephalus in dogs caused by canine parainfluenza virus.
Intracranial infection of neonatal dogs with canine parainfluenza virus (strain 78-238) progressed from an acute phase of encephalitis to a chronic phase of internal hydrocephalus. Acute encephalitis was characterized ultrastructurally by laminar cortical necrosis, neuronal degeneration, neocapillary formation, reactive gliosis, and ependymitis. Viral nucleocapsids were seen in the cytoplasm of...
