title: Effect of alpha-tocopherol, pyridoxine and dexpanthenol on the stress in crease of nonesterified fatty acids levels in the brain.
abstract: The supposed antistress effect of vitamins-alpha-tocopherol, pyridoxine and dexpanthenol (pantothenic acid precursor)--was followed on the model of nociceptive stress in laboratory rats. The decrease of the stress enhancement of nonesterified fatty acids (NEFA), estimated in the brain cortex, hypothalamus and the brain stem, was taken for the indicator of the antistress effect. Nonesterified fatty acids were determined with the help of gas chromatography following the separation performed by thin layer chromatographic method. Five-day application of alpha-tocopherol acetate (per os, 300 mg.kg-1) led to a decrease of the stress enhancement of arachidonic acid level in the brain stem.
