Progesterone treatment in rats after severe global cerebral ischemia promotes hippocampal dentate gyrus neurogenesis and functional recovery.

abstract：OBJECTIVES:Brain death is a clinical diagnosis often confirmed with supplementary tests. In this study, we examined the relationship between brain death and the partial pressure of brain tissue oxygen (PbtO(2)). We hypothesized that a sustained PbtO(2) of 0 is associated with brain death. METHODS:One hundred and twent...
