Myo-inositol-1,4,5-triphosphoric acid (IP3) formation stimulated by (+-)-1-amino-1,3-cyclopentane-trans-dicarboxylic acid (trans-ACPD) was examined in the cortex, hippocampus and cerebellum of iron-induced epileptic rats and epileptic El mice. Increased IP3 formation by trans-ACPD was observed in the cortex, hippocampus and cerebellum of iron-injected rats while it was found in the hippocampus and cerebellum of the saline-injected control rats. Increased IP3 formation by trans-ACPD was remarkably higher in the hippocampus of iron-injected rats than the other regions. Increased IP3 formation by trans-ACPD was observed in the cortex, hippocampus and cerebellum of ddY mice, while such an increase was found only in the cerebral cortex and not in the hippocampus and cerebellum of El mice. These findings suggest that the inositol response may be involved in the seizure mechanisms of iron-induced epileptic rats and epileptic El mice in some different forms.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon

D004827 Epilepsy A disorder characterized by recurrent episodes of paroxysmal brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology (e.g., post-traumatic), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal patterns (e.g., nocturnal epilepsy).

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.

D015544 Inositol 1,4,5-Trisphosphate Intracellular messenger formed by the action of phospholipase C on phosphatidylinositol 4,5-bisphosphate, which is one of the phospholipids that make up the cell membrane. Inositol 1,4,5-trisphosphate is released into the cytoplasm where it releases calcium ions from internal stores within the cell's endoplasmic reticulum. These calcium ions stimulate the activity of B kinase or calmodulin. 1,4,5-InsP3,Inositol 1,4,5-Triphosphate,Myo-Inositol 1,4,5-Trisphosphate,1,4,5-IP3,Myoinositol 1,4,5-Triphosphate
