Purpose: To report a case of ruptured abdominal aortic aneurysm (AAA) treated with a commercially available endoluminal graft.
Case Report: Ruptured AAA was diagnosed in a 58-year-old man with lower abdominal pain, hypotension, and syncope. A contrast-enhanced computed tomographic (CT) scan confirmed the presence of a 7-cm ruptured infrarenal AAA associated with a large retroperitoneal hematoma.
The manner in which the human brain processes grammatical-syntactic and lexical-semantic functions has been extensively debated in neurolinguistics. The discreteness and selectivity of the representation of syntactic-morphological properties in the dominant frontal cortex and the representation of the lexical-semantics in the temporo-parietal cortex have been questioned. Three right-handed adult male neurosurgical patients undergoing left craniotomy for intractable seizures were evaluated using various grammatical and semantic tasks during cortical mapping.

The terminology was first used for unexplained behaviors associated with food pellet ratio contingencies in food deprived rats (Falk, 1971). Clinically, unrelated and complex excessive behaviors were also noted with brainstem and diencephalic discharges (Andy, 1986, 1989 and 1995; Andy and Jurko, 1986).

Since NMDA blockers are known to reduce the locomotor stimulatory and toxic effects of cocaine, it was speculated that dextrorphan would attenuate cocaine-induced behavioral excitatory motor activity associated with and without mechanical perturbation of the brainstem.
Technique: Motor activity was recorded following dextrorphan and/or cocaine challenge in 25 SHR rats.
