Objective:
To study the mechanical properties of sciatic nerve in rats with chronic alcoholism (CA) and intervened with bone marrow mesenchymal stem cells (BMSCs) and to provide biomechanical basis for clinical practice.
Methods:
the serum of the BMSCs-intervened CA rats was sampled and determined the contents of malondialdehyde (MDA), metallothionein (CAS, MT), and Glutathione/r -glutamyl cysteinyl/glycine (GSH); meanwhile, the rats' sciatic nerve was tested the tensile and observed the histomorphological changes.
Results:
The mechanical properties of sciatic nerve in BMSCs-intervened CA rats, as well as the serum levels of MT and GSH, were significantly different from those in the basic fibroblast growth factor (bFGF)-intervened CA rats (p < 0.05).
Conclusions:
BMSCs intervention can restore the levels of MT, GSH, MDA, histomorphology, and tensile mechanical properties in CA animal model, and its effects on repairing sciatic nerve are obvious.
