Effects of adrenaline on the action potential of sympathetic ganglion cells in bullfrogs.
The effects of catecholamines (adrenaline, noradrenaline and isoproterenol) on ionic conductance changes during the generation of action potentials of bullfrog sympathetic and spinal ganglion cells were studied with intracellular microelectrodes. In sympathetic ganglion cells, adrenaline (3X10(-5)-1X10(-3)M) reversibly decreased the peak amplitude and positive after-potential of action potentia...
متن کاملModulatory effect of ATP on the release of acetylcholine from presynaptic nerve terminals in bullfrog sympathetic ganglia.
The effect of adenosine triphosphate (ATP) on the release of acetylcholine (ACh) from presynaptic nerve terminals was investigated in bullfrog sympathetic ganglia. ATP decreased the amplitude and quantal content of fast excitatory postsynaptic potentials (fast e.p.s.p.s) calculated from the variance of fast e.p.s.p. amplitude in a low Ca2+-high Mg2+ Ringer solution. The frequency of miniature e...

15 صفحه اولthe effects of planning on accuracy and complexity of iranian efl students’ written narrative task performance
this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
15 صفحه اولLocalization of ATP-gated P2X receptor immunoreactivity in rat sensory and sympathetic ganglia.
The distribution of P2X1, P2X2, P2X3, P2X4, P2X5 and P2X6 receptors, a family of ATP-gated cation channels, in rat trigeminal, dorsal root, nodose, superior cervical, and coeliac ganglia was studied immunohistochemically. It was found that polyclonal antibodies for the six P2X receptor subtypes could label over 90% of neurones in these ganglia to different intensities. There was also considerab...
