Abstract：
:We wanted to determine what happens to brain PCr and ATP relative to that in liver during a series of dietary manipulation consisting of a severe fast, during eating (when nutrients are intermittently supplied), and during and after PN-100, when an excess amount of nutrients are continuously supplied, using 31P-NMR spectroscopy, in rats randomized to a Fast or Fed group in which energy was provided either as chow or as PN-100. Liver ATP concentration, and brain and liver 31P-nuclear magnetic resonance (NMR) spectras were measured serially. Brain energy metabolism was not different between groups and among days. In contrast, Fasted group showed increased liver ATP/Pi ratio and decreased ATP concentration and ATP/phosphomonoester ratio, there being no difference between Fed and PN-100 groups. Data suggest that brain energy metabolism is maintained regardless of whether energy is supplied intermittently or continuously, and during a negative caloric intake period, brain energy metabolism is quantitatively preserved, suggesting that ATP production by liver is subservient to brain ATP state.

杂志文章abstract：:Electric shocks lead to lasting behavioral deficits in rodents, and as such are often used to model post-traumatic stress disorder (PTSD) in the laboratory. Here we show that a single exposure of rats to 3 mA-strong shocks results in a marked social avoidance that lasts at least 28 days; moreover, the response intensi...
