Effects of inflammatory agents on endothelial lysosomal fragility and their inhibition by anti-inflammatory drugs.

abstract：:1 The effects of opioids on synaptic transmission in cat sacral parasympathetic colonic ganglia were studied in vitro, using intracellular electrophysiological techniques. Electrical stimulation of the pelvic nerve evoked fast excitatory postsynaptic potentials (e.p.s.ps), which were blocked by hexamethonium and tetro...
