The effects of single and multiple seizures on cholecystokinin (CCK) mRNA levels in amygdala of audiogenic seizure-prone rats (P77PMC) were examined by in situ hybridization. The main results are as follows: (1) CCK mRNA positive neurons (No/0.01 mm(2)) in amygdala showed a transient increase in number from the 8+/-1 to 58+/-5 (P<0.01) in 30 min and then returned to the control value in 2 h (9+/-2, P>0.05), and (2) in the multiple consecutive seizure rats the increase in 30 min (22+/-3) was less than that in the single seizure rats (P<0.01), and the number returned to normal in 1 h (6+/-1, P>0.05). These data indicate that the transient increase in CCK mRNA level in amygdala following single or multiple consecutive seizures of P77PMC may be involved in anti-convulsant mechanisms in response to acute seizures.

D002766 Cholecystokinin A peptide, of about 33 amino acids, secreted by the upper INTESTINAL MUCOSA and also found in the central nervous system. It causes gallbladder contraction, release of pancreatic exocrine (or digestive) enzymes, and affects other gastrointestinal functions. Cholecystokinin may be the mediator of satiety.

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.

D012333 RNA, Messenger RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

D020195 Epilepsy, Reflex A subtype of epilepsy characterized by seizures that are consistently provoked by a certain specific stimulus. Auditory, visual, and somatosensory stimuli as well as the acts of writing, reading, eating, and decision making are examples of events or activities that may induce seizure activity in affected individuals.
