Hypothesis
Does human C-peptide prevent early neuropathy in type 1 diabetic BB/Wor-rats?
Conclusion
Human C-peptide administration prevents early diabetic neuropathy in a dose-dependent manner in rats.
Supporting Evidence
- 100g and greater doses of hrC-peptide completely prevented nerve conduction defects.
- 500g and 1000g of hrC-peptide completely prevented deficits in Na+/K+-ATPase activity.
- Increasing doses of hrC-peptide promoted nerve fiber regeneration.
Takeaway
Giving a special protein called C-peptide to diabetic rats helps protect their nerves from damage.
Methodology
Diabetic BB/Wor-rats were given increasing doses of human recombinant C-peptide, and nerve conduction velocity and structural changes were assessed over two months.
Limitations
The study was conducted on rats, and results may not fully translate to humans.
Participant Demographics
Fifty prediabetic male BB/Wor-rats and ten age- and sex-matched non-diabetes prone BB/Wor-rats.
