Lipopolysaccharide-dependent enhancement of adherence-mediated chemiluminescence response of polymorphonuclear leukocytes.

Adherence of resting polymorphonuclear leukocytes to nylon fibre increased the chemiluminescence response (CL) from 99,400 to 910,300 cpm/25,000 PMNL. This effect could be amplified by lipopolysaccharide (LPS) priming of granulocytes in a dose-dependent fashion. The results of nylon fibre adherence experiments suggest an in vitro model that might approximate certain conditions of in vivo PMNL-endothelial adherence and respiratory burst activation, and these reactions of polymorphonuclear leukocytes may contribute to the pathomechanisms of the Adult Respiratory Distress Syndrome.

Source localization of induced cortical oscillations during tactile finger stimulation.

We investigated the EEG beta event-related synchronization (ERS) after tactile finger stimulation in three subjects. Prior studies from our group using electrical stimulation and self-paced movement showed a beta rebound within one second after stimulation respectively movement offset. As the tactile-stimulation-data showed a similar ERS behaviour, we extracted the cortical sources for this beta rebound by the linear estimation method in order to see whether the representation areas of different fingers were distinguishable (as is possible with MEG data). Although realistic head models of two subjects were used for the calculations the fingers could not be spatially distinguished. However, regarding the whole spatio-temporal pattern of the ERS for different fingers clear differences can be observed.
