  • Dried leaves from Cedrela sinensis A. Juss. (CS), have been observed to possess various pharmacological activity and contain various antioxidant constituents. The protective effect of ethanol extract of CS on hydrogen peroxide $(H_2O_2)-induced$ neurotoxicity was examined using primary cultured rat cortical neurons in the present study. Exposure of cultured neurons to 100 ${\mu}M\;H_2O_2$ caused a significant neuronal death as assessed by a 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium bromide (MTT) assay and Hoechst 33342 staining. The addition of CS, over a concentration range of 10 to $50{\mu}g/m{\ell}$, concentration-dependently prevented the $H_2O_2-induced$ neuronal apoptotic death. CS $(50{\mu}g/m{\ell})$ significantly inhibited $H_2O_2-induced$ elevation of the cytosolic $Ca^{2+}$ concentration $([Ca^{2+}]_c)$, which was measured by a fluorescent dye, Fluo-4 AM. CS (30 and $50{\mu}g/m{\ell})$ inhibited glutamate release and generation of reactive oxygen species (ROS) induced by $100{\mu}M\;H_2O_2$. These results suggest that CS may mitigate the $H_2O_2-induced$ neurotoxiciy by interfering with the increase of $[Ca^{2+}]_c$, and then inhibiting glutamate release and generation of ROS in cultured neurons.

  • Objective : To carry out the oriental medicine treatment on a patient with oculomotor nerve palsy accompanied by Diabetes mellitus complication history Methods : We conducted one patient with oculomotor nerve palsy at Won-Kwang University Kwang-Ju Oriental Medical Hospital. We treated patient by herbal medicine, acupuncture, etc. Results : We had an effect that one patient's symptom had improved. Conclusion : We suggest that the oriental medical treatment and management have an effect with oculomotor nerve palsy accompanied by DM complication history.
