CAT and hyperthyroidism: SOD levels (p < 0.05) and CAT levels (p < 0.001) were all significantly decreased in the hyperthyroidism model group compared to the normal group, while EEP-L (p < 0.001), EEP-M (p < 0.001), and EEP-H (p < 0.001) were found to significantly increase SOD levels and CAT levels in hyperthyroid mice.
