Fever development for animals receiving LPS in experiment 1 demonstrates a temporal relationship -- with increments in plasma levels of LPS and pyrogenic cytokines obtained in experiment 2 after administration of LPS either i.p. or i.v. Vagotomy had no discernible effect on the responses regardless of the route of administration of LPS.

Repeal of the mandatory helmet law was associated with an increase in the nonhelmeted crash scene fatality rate. After the repeal, there was a disproportionately higher admission rate for nonhelmeted motorcycle crash survivors. These patients had an increased use of hospital resources and poorer reimbursement of charges compared with their helmeted counterparts. This resulted in significantly higher unreimbursed charges. States considering repeal of their mandatory adult helmet laws should consider the potential negative financial impact on their health care system and the increased morbidity associated with nonhelmeted motorcycle riders involved in a crash.
