title: [Infra-red spectra and ATPase activity of cardiac sarcoplasmatic reticulum under extreme conditions].
abstract: The study of infra-red spectra of cardiac microsomal fraction revealed the changes in the membrane structure, induced by acute hypoxia and hypothermia in one's lifetime. These changes affect alpha- and beta-conformations of protein, phospholipid part of sarcoplasmic reticulum and are accompanied by the change in the activity of membrane-bound ATPases.
