Content of adenosine phosphate, creatine phosphate, Pi, lactate and ATPase activity were studied in brain of 8-10- and 25-27-months old rats. Content of ATP and ADP and the Na+, K+-ATPase activity were decreased while the level of Pi was increased in rat brain cortex during ageing. Administration of vasopressin caused an increase in lactate, Pi and Na+, K+-ATPase activity, whereas creatine phosphate decreased in the adult rat hypothalamus. Changes in energy metabolism were more pronounced in old rats: simultaneously with the decrease in creatine phosphate and more marked, as compared with adults, increase in Pi and lactate, the content of ATP decreased, ADP and AMP - increased and the Na+, K+-ATPase was distinctly activated in stem and brain cortex.
