Atrial natriuretic peptide in the rat brain and plasma during clinical death and after resuscitation.
By means of the radioimmunologic method changes of ANP content in the rat brain and plasma have been evaluated during 5-min clinical death and up to 2 hr after resuscitation. Ischemia did not produce significant rise of ANP immunoreactivity in the brain, however, in the early postresuscitation period its reversible increase was noted with the peak value at 15th min. The content of peptide in plasma significantly increased at the end of clinical death and 5 min after resuscitation. The obtained results can support the notion of quantitative relationship between concentration of ANP and cGMP content in the brain in vivo.
