Chen et al. [75] found that cardamomum volatile oil can reduce the urine protein content of acute kidney injury rats; reduce renal body index; improve renal tubular pathology; reduce MDA, NO content, and NOS activity in renal tissue; and increase SOD and GSH-Px activity in the kidney tissues so that cardamomum can improve the acute kidney injury of rats caused by gentamicin to a certain extent. This evidence concerns the gene SOD1 and acute kidney injury.
