Facilitation of kindling by convulsions induced by cocaine or lidocaine but not pentylenetetrazol. 1981

J S Stripling, and C Hendricks

The effect of drug-induced convulsions on kindling was studied in male Long-Evans rats. In Experiment 1 rats experienced a single convulsion induced by the intravenous infusion of cocaine, lidocaine, or pentylenetetrazol (PTZ), or received a control infusion of saline. Beginning eight days later all animals were kindled by daily stimulation of the olfactory bulb. Animals which had been convulsed by cocaine or lidocaine kindled significantly faster than either saline controls or PTZ-convulsed animals, which did not differ significantly. Experiment 2 was conducted to determine if an effect of PTZ on kindling could be obtained with repeated convulsions. Rats experienced three convulsions induced by cocaine or PTZ at 72 hr intervals, or control infusions of saline. Kindling began on the eighth day after the last infusion. Cocaine-convulsed animals again kindled significantly faster than saline or PTZ-convulsed animals, which did not differ significantly. The cocaine animals also had significantly longer afterdischarges than the saline group at the end of kindling and when stimulated again 21 days after kindling was completed. These results suggest that the facilitating effect of cocaine-induced convulsions is not a general property of all convulsants but is a more specific effect which is apparently shared by other local anesthetics.

UI	MeSH Term	Description	Entries
D007696	Kindling, Neurologic	The repeated weak excitation of brain structures, that progressively increases sensitivity to the same stimulation. Over time, this can lower the threshold required to trigger seizures.	Kindlings, Neurologic,Neurologic Kindling,Neurologic Kindlings
D008012	Lidocaine	A local anesthetic and cardiac depressant used as an antiarrhythmia agent. Its actions are more intense and its effects more prolonged than those of PROCAINE but its duration of action is shorter than that of BUPIVACAINE or PRILOCAINE.

D009830	Olfactory Bulb	Ovoid body resting on the CRIBRIFORM PLATE of the ethmoid bone where the OLFACTORY NERVE terminates. The olfactory bulb contains several types of nerve cells including the mitral cells, on whose DENDRITES the olfactory nerve synapses, forming the olfactory glomeruli. The accessory olfactory bulb, which receives the projection from the VOMERONASAL ORGAN via the vomeronasal nerve, is also included here.

D010433	Pentylenetetrazole	A pharmaceutical agent that displays activity as a central nervous system and respiratory stimulant. It is considered a non-competitive GAMMA-AMINOBUTYRIC ACID antagonist. Pentylenetetrazole has been used experimentally to study seizure phenomenon and to identify pharmaceuticals that may control seizure susceptibility.

D003042	Cocaine	An alkaloid ester extracted from the leaves of plants including coca. It is a local anesthetic and vasoconstrictor and is clinically used for that purpose, particularly in the eye, ear, nose, and throat. It also has powerful central nervous system effects similar to the amphetamines and is a drug of abuse. Cocaine, like amphetamines, acts by multiple mechanisms on brain catecholaminergic neurons; the mechanism of its reinforcing effects is thought to involve inhibition of dopamine uptake.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001522	Behavior, Animal	The observable response an animal makes to any situation.	Autotomy Animal,Animal Behavior,Animal Behaviors
D012640	Seizures	Clinical or subclinical disturbances of cortical function due to a sudden, abnormal, excessive, and disorganized discharge of brain cells. Clinical manifestations include abnormal motor, sensory and psychic phenomena. Recurrent seizures are usually referred to as EPILEPSY or "seizure disorder."
