Modulation of the acoustic startle response by film-induced fear and sexual arousal.

The response matching model of Lang, Bradley, and Cuthbert (1992) predicts startle reflex facilitation during negative relative to positive emotional states. Using slide and imagery paradigms, larger eyeblink responses to startle probes for unpleasant than for pleasant conditions have consistently been reported. The present study extended the previously observed relationship between valence and startle to more complex stimuli, namely 1-min film fragments.

Indomethacin enhancement of human natural killer cytotoxicity to herpes simplex virus infected cells in vitro and in vivo.

Indomethacin, a prostaglandin synthetase inhibitor, increased human mononuclear cell (MC) natural killer cytotoxicity (NKC) to herpes simplex virus (HSV) infected cells in vitro at concentrations of 2 X 10(-10)M (p less than .025). Infant mice were significantly (p less than 0.
