| Abstract: | Ginsenoside has been used to treat diabetes, while ginsenoside Rg3 is the main active ingredient component of ginseng and is used to study its effects on lung tissue damage in diabetic rats. In this paper, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and flow cytometry were applied to detect the proliferation and apoptosis of BEAS-2B cells treated with different concentrations of Rg3. The inflammatory response and pathological change in the lung tissue of diabetic rats treated with Rg3 were evaluated by enzyme-linked immunosorbent assay, quantative real-time polymerase chain reaction, and hematoxylin and eosin staining immunohistochemistry. Meanwhile, PI3K and MAPK signaling pathway proteins in lung tissue were determined by Western blot analysis. The results showed that ginsenoside Rg3 had no significant influence on the proliferation and apoptosis of BEAS-2B cells. Ginsenoside Rg3 can inhibit inflammatory response and promote the activation of PI3K and MAPK signaling pathways to prevent damages of lung tissues induced by hyperglycemia. The protective effect provided by ginsenoside Rg3 indicates that ginsenoside Rg3 is a potential drug for the treatment of diabetes. |
