Surfactant-potentiated increases in intracranial pressure in a mouse model of Reye's syndrome.


Severe encephalopathy, the usual cause of death in Reye's syndrome (RS), is characterized by cerebral edema with associated increases in intracranial pressure (ICP). In previous studies, we have shown that exposure of neonatal mice to nontoxic doses of an industrial surfactant and subsequent infection with mouse-adapted influenza B (Lee) virus result in a significant increase in mortality rate and that this is associated with several of the characteristic features of human RS. In the present study we have measured ICP in the young mice undergoing their version of the disease, and we now report that the animals treated with surfactant plus virus experience increases in intracranial pressure that are significantly in excess of those in any of the three control groups. These findings support our hypothesis that this and the other abnormal biochemical and morphological responses in RS are related in some manner to a chemically compromised host.
