Abstract:
Objective To study the rehabilitative effect of velvet antler polypeptides-PLGA compound membrane on peripheral nerve injury.Methods Two doses(3 and 15 mg?g~(-1)) of velvet antler polypeptides-PLGA compound membrane(thickness 50 ?m) were used to wrap the sutures of severed sciatic nerves,which were compared with nerve sutures only.2,4 and 6 weeks post-operation,general morphological,electrophysiological,histological and electron microscopic observations and examinations were investigated.Results There were no ulcers in the nars and toes in the treatment group,light conglutination appeared in nerve anastomosis and around tissues.At 6th week post-operation,conglutination was alleviated obviously than 2 weeks post-operation;findings from latency inducing potentials of calf triceps dominated by sciatic nerves showed that recover ratios(%) in treatment group((2 weeks:)9.07?1.44,8.02?1.41;6 weeks: 49.87?9.69,50.11?6.11) were better than those in control group((2 weeks:)2.52?1.83;6 weeks:30.31?6.32) obviously in each time(P
