[Anti-aging action of the total lactones of ginkgo on aging mice].

OBJECTIVE

To investigate the effects of total lactones of ginkgo on aging by using D-galactose induced aging mice and natural aging mice.

METHODS

By using D-galactose induced aging mice, to detect the LF content in heart and liver, the Hyp content in liver, the MAO, GSH-Px activities and the NO content in cerebrum. The apoptosis of cerebral cell was determined by terminal deoxy-nucleotidyl transforase-mediated dUTP-digoxigenin nick end-labeling (Tunel) in natural aging mice.

RESULTS

TLG was shown to increase the GSH-Px activities, reduce the NO content and decrease the MAO activity in cerebrum. Meanwhile, TLG was found to reduce the LF content in liver and heart and raise the Hyp content in liver. TLG was shown to inhibit apoptosis of cerebral cell and decrease the number of apoptotic cells in the brain.

CONCLUSIONS

TLG possesses effect on antiaging via attenuating lipid peroxidation and NO and apoptosis of cerebral cells.
