Rats were kindled by intraperitoneal injection of pentylenetetrazol (PTZ) (30 mg/Kg) every 48 h. Once kindled, some of the animals received a single injection of cysteamine (200 mg/Kg). Somatostatin-like immunoreactivity (SLI) and 125 I-Tyr11-somatostatin binding were measured in the frontoparietal cortex and hippocampus of the two experimental groups and the control rats. After PTZ kindling the following was observed: 1) SLI content was increased in the two areas; 2) Somatostatin receptor affinity decreased in the frontoparietal cortex and was unaltered in the hippocampus; 3) The number of somatostatin receptors decreased in the hippocampus and was unaltered in the frontoparietal cortex. Cysteamine, an agent which depletes brain somatostatin and suppresses kindled seizures in PTZ-treated rats, reversed the altered SLI levels and binding in these rats.

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
D007700	Kinetics	The rate dynamics in chemical or physical systems.

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.

D002540	Cerebral Cortex	The thin layer of GRAY MATTER on the surface of the CEREBRAL HEMISPHERES that develops from the TELENCEPHALON and folds into gyri and sulci. It reaches its highest development in humans and is responsible for intellectual faculties and higher mental functions.

D003543	Cysteamine	A mercaptoethylamine compound that is endogenously derived from the COENZYME A degradative pathway. The fact that cysteamine is readily transported into LYSOSOMES where it reacts with CYSTINE to form cysteine-cysteamine disulfide and CYSTEINE has led to its use in CYSTINE DEPLETING AGENTS for the treatment of CYSTINOSIS.
