title: Myelin lipids and proteins in experimental global ischemia.
abstract: The experiments were performed on white rats, in which clinical death was induced according to the method described by Korpatchev et al. (1982). After cardiac arrest and cessation of respiratory function lasting 5 minutes resuscitatory action was performed. The lipids and proteins of the cerebral myelin fraction were studied in animals sacrificed 1, 9 and 14 days after global ischemia. The obtained results lead to the following conclusions: 1. Myelin lipids in postreanimation syndrome are characterized by a marked increase in cholesteryl esters and a mild one of lysophosphatidylcholine content. 2. Myelin lipids in the predemyelinating period demonstrate a general pattern of reaction, notwithstanding to the character of the primary noxious agent. 3. After global ischemia a great fall of small basic protein in the myelin fraction and subsequently of SBP to LBP ratio occurred. 4. Various noxious agents affect different proteins of the myelin membranes and the resulting changes seem to be characteristic for various pathological processes.
