title: [Toxicological evaluation of chronic exposure to dinil].
abstract: Experiments on rats were carried out to study the effect of dinil on the animals on chronic intake of the agent in the quantities exceeding the maximum permissible concentrations by many times. Despite few biochemical changes, there was a certain tension of adaptive processes, which appeared as a change mainly in the integral characteristics of the plasma amino acid pool. The observed changes in the levels of neurotransmitters and neuroactive amino acids in the striatum, midbrain, and hypothalamus are characterized by specific characteristics and may underlie the negative effect of dinil on central nervous system functions. Long-term administration of the agent to the animals did not induce pronounced morphological and biochemical disturbances in the tissues of the liver, heart, and kidneys. Changes in the concentrations of serotonin and neuroactive amine acids in the brain regions might have the greatest consequences to the body. Since the detectable changes in a number of metabolites are likely to be functional in the given period (monthly dinil use), an attempt to correct developing disorders with metabolic therapy agents may be recommended.
