Effect of gypenosides on the activity of superoxide dismutase induced by H₂O₂. Gypenoside preintervention can downregulate the level of reactive oxygen species in orbital fibroblasts of GO patients under H₂O₂ stimulation. After intervention in accordance with the requirements of the group. The orbital fibroblasts of GO patients in each treatment group were localized in situ by ROS fluorescence intensity, and then, (a) was photographed by fluorescence microscope. And the fluorescence values of each group of ROS were detected after the excitation light and emission light were adjusted by full-wavelength enzyme labeling instrument. The result is expressed as a percentage of unprocessed control values. Three samples from each of the three GO and non-GO donors were taken for the experiment. All detections are repeated 3 times, with 3 replicate wells each time (^∗ as P < 0.05 and ^∗∗ as P < 0.01; P < 0.05 means the difference is statistically significant, and P value is analyzed by two-way ANOVA).
