2. Pretreatment of either isoniazid, an aminoacid decarboxylase inhibitor, or GABA receptor antagonist picrotoxin prevented thedepressant effect of diazepam on the amplitude of phrenic discharge.
3. It was found that the antagonist picrotoxin was unable to block the liver fluke to the excitatory effect of GABA, while it could partially block the roundworm to the inhibitory effect of GABA.

4. Conclusion: Melatonin does not exhibit its potentiation sleeping time in mice through melatonin 3 receptor. Hypnotic activity of melatonin may be mediated through picrotoxin site on GABAA receptor.
5. Objective to observe the kindling model of Sprague Dawley (SD) rats induced by injection of different doses of picrotoxin (PTX) intraperitoneally, and to evaluate the effect of the drug on the model.

6. In midbrain slices from rats treated with saline or a single dose of cocaine, LTP could not be induced in VTA dopamine neurons unless GABA-mediated inhibition was reduced by bicuculline or picrotoxin.
