PDLLA/β-TCP/HA/CHS/NGF Sustained-release Conduits for Peripheral Nerve Regeneration

Using nerve guide conduits (NGCs) to promote the regeneration of PNI is a feasible alternative to autograft.Compared with NGCs made of single material,composite NGCs have a greater development prospect.Our previous research has confirmed that poly(D,L-lactic acid)/β-tricalcium phosphate/hyaluronic acid/chitosan/nerve growth factor (PDLLA/β-TCP/HA/CHS/NGF) NGCs have excellent physical and chemical properties,which can...  (本文共7页) 阅读全文>>

Evaluation of a Novel Bioabsorbable PRGD/PDLLA/β-TCP/NGF Composites in Repair of Peripheral Nerves

Peripheral nerve regeneration using a novel nerve conduit (PRGD/PDLLA/β TCP/NGF) was evaluated, which was made of RGD peptide modified poly{(lactic acid)-co-[(glycolic acid)-alt-(L-lysine)]} (PRGD), poly(d,l-lactic acid) (PDLLA) andβ-tricalcium phosphate (β-TCP). And the effectiveness was compared with that of PRGD/PDLLA/β-TCP, PDLLA and autograft in terms of nerve regeneration across a gap. Both of biodegradablity a...  (本文共6页) 阅读全文>>

Degradation Characteristic of PDLLA/HA Composite Fiber in vitro

The in vitro degradation characteristic of the poly D, L-lactic acid (PDLLA)/ hydroxyapatite (HA) compound fibers were investigated. The compound fibers were immersed in static phosphate buffer at 37℃ to degrade for 22 weeks. The changes in pH value of the buffer solution, the mech...  (本文共2页) 阅读全文>>
