摘要：
Age-related impairments of cognitive and motor function have been linked to a number of deleterious morphological and functional changes involving different areas of the brain. Loss of neurotransmitters, their receptors and responsiveness to neurotransmitters are key manifestations of neurological ageing and age-related disorders. In the present investigation we have evaluated the effect of DL-alpha-lipoic acid on neurotransmitters in discrete brain regions of young and aged rats. The levels of neurotransmitters were found to be lowered in aged rats. Moreover, DL-alpha-lipoic acid treated aged rats showed a increase in the status of dopamine, serotonin and norepinephrine. The results of this study provide evidence that DL-alpha-lipoic acid (a potent antioxidant) treatment can improve neurotransmitters during ageing. Hence, it can be concluded that DL-alpha-lipoic acid act as a potent neuromodulator in the brain of aged rats. (C) 2002 Elsevier Science Inc. All rights reserved.
