Hypothesis

Kihi-to can improve memory deficits and promote neurite growth and synapse reconstruction in Alzheimer's disease model mice.

Conclusion

Kihi-to clearly improved memory impairment and losses of neurites and synapses.

Supporting Evidence

  • Kihi-to administration improved memory acquisition and retention in Aβ(25–35)-injected mice.
  • Kihi-to treatment restored neuritic and synaptic densities in the cerebral cortex and hippocampus.
  • Kihi-to inhibited Aβ(25–35)-induced cell death in cultured cortical neurons.
  • Kihi-to reduced calpain levels and increased calpastatin levels in the brain.

Takeaway

Kihi-to is a herbal medicine that helps mice with memory problems and damaged brain cells get better.

Methodology

The study used Alzheimer's disease model mice to test the effects of Kihi-to on memory and neurite growth, employing behavioral tests and immunohistochemistry.

Limitations

The study primarily focused on animal models, and further research is needed to confirm the effects in humans.

Participant Demographics

Male ddY mice, 7 weeks old.
