title: Effect of clinical death on inositol 1,4,5-trisphosphate in the rat brain.
abstract: Changes of inositol 1,4,5-trisphosphate content in the rat brain have been evaluated by means of the radioimmunologic method during 5-min clinical death and up to 2 hrs after resuscitation. Ischemia produced a decrease of IP3 content in the brain on the average to 63% of the control values. IP3 concentration in the brain increased on the average to 197% of the control values at the 15th min after resuscitation, and decreased to 127% at the 60 min. Two hours after resuscitation the IP3 content in the brain again increased on the average to 187%. The new data on brain metabolism in the ischemic conditions and the role of IP3 as the second messenger and mediator of neuromodulation processes are discussed.
