✦ Synopsis

In this work, the light-induced photon emission (IPE) by suspensions of mammalian cells was examined. IPE is extremely low and for detection a single photon counting device with a cooled EM1 9558QB photomultiplier tube was used. The mammalian cells in this study were from different tissues and different mammalian species including cat, Chinese hamster, cow, dog, human, monkey, mouse and rat. The IPE was detected in all mammalian cells tested, but was different for the various cell types, ranging from 4 to 100 photons per lo4 cells. Although our data agree with previous studies in that the IPE of non-fibroblastic normal cells is distinct from that of malignant cells our results reveal that cells of fibroblastic origin show the highest IPE values.

Several lipoxygenase products were able to enhance ultraweak light emission and membrane permeability of human erythroleukemia K562 cells. In particular, 13-hydroperoxyoctadecadienoic acid (13-HPOD) was more effective than hydrophilic hydroperoxides, like H 2 O 2 and tert-butyl hydroperoxide. The en

Retinal horizontal cells exhibit large receptive fields derived from their extensive electrical coupling by means of gap junctions. The conductance of these gap junctions seems to be regulated by dopamine acting through a cAMP-mediated cascade. There is now abundant evidence that extracellular dopam
