Mark Schaller and Will Gervais psychologists at U of BC suggest that just seeing pictures of symptoms of infectious disease, ie. sneezes, lesions, boosts our immunity. Subjects were shown photos associated with infectious illness or of guns (control). Participants white blood cells were then incubated with bacteria. Those exposed to the images of infection demonstrated higher levels of the proinflammatory cytokine interleukin-6 (IL-6) compared with the control (gun picture exposed) subjects.This study is the first evidence that visual perception of other people's illness can boost our immunity.

Hasan Alam at Mass General suggests that survival after major trauma associated with major blood loss could be improved by administering valproic acid (Depakote) to the injured. Depakote is used neurologically as an anti-seizure and migraine preventative medicine. Valproic acid aids cells survival on less oxygen by its histone deacetylase inhibitory properties. Found first to be effective on injured rats then on pigs experimentally. More than 500,000 people per year bleed to death as a result of major trauma including motor vehicle accidents and combat wounds.
