Kim YC, Kim SR, Markelonis GJ, Oh TH (1998): Ginsenosides Rb1 and Rg3 protect cultured rat cortical cells from glutamate-induced neurodegeneration. J Neurosci Res 53:426–432. On page 427 of the article referenced above, under the heading Assessment of Neurotoxicity in the Materials and Methods section, the formula given for the assessment of percentage cell viability was printed incorrectly. The formula is correctly stated in a footnote to Table 1 on page 429. The correct formula appears below: 100 × (OD of glutamate + ginsenoside-treated – OD of glutamate-treated)/(OD of control – OD of glutamate-treated). The publisher regrets this error.
