Protective effect of 80% ethanolic extract from Gimcheon 1ho (GC) cultivar walnut (Juglans regia): (a) cell viability from H₂O₂-induced cytotoxicity in PC12 cells; (b) cell viability from high-glucose-induced cytotoxicity in PC12 cells; (c) cell viability from H₂O₂-induced cytotoxicity in HT22 cells; (d) cell viability from high glucose-induced cytotoxicity in HT22 cells. Results shown are mean ± SD (n = 3). Data are statistically represented with * = significantly different from the NC group, and ^# = significantly different from PM group; * and ^# p < 0.05, ** and ^## p < 0.01. Bold line indicates mean.
