ObjectiveTo study the effect of ginsenoside Rg1 on the pathological changes of rat optic nerve injury. MethodsThe model of rat optic nerve injury was established, the rats were divided into the experimental group and control group,intraperitonealiy injected ginsenosides Rgl (10mg/kg) to experimental group of rats for 20days ,meanwhile intraperitonealiy injected the same volume of saline to the control group,took eyeball and optic nerve from the optic nerve injury eye and the normal eye in both groups ,HE staining,SABC immunohistochemical staining of Bcl-2, neurocan were analyzed. ResultsHE staining results showed the morphological difference on optic nerve cells from control group and the optic nerve injury group. Immunohistochemistry showed the neuronal cell apoptosis was significantly increased after optic nerve injury. The intraperitoneal injection of ginsenoside Rg1 could significantly improve the situation of cell apoptosis. The significant increment of fiber protein may be partly related to the improvement of cell apoptosis, but the principle was not clear. ConclusionGinsenoside Rg1 had protective effect on rat optic nerve injury.
Résumé
Objective To separate the SO-Rb 50cells antigen corresponding to the monoclonal antibody of anti-retinoblastoma. Methods The antigen corresponding to the monoclonal antibody of anti-retinoblastoma was separated elementarily by ion-exchange chromatography, and was identified by dot-blotting using the monoclonal antibody of anti-retinoblastoma. The target protein band of the antigen was separated in light of sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Results A special unmixed band of SO-Rb 50cells antigen was separated with the relative molecular weight of 83?103. Conclusion The antigen corresponding to the monoclonal antibody of anti-retinoblastoma could be separated from SO-Rb 50cells.
