Chemical compounds from Salvia miltiorrhiza (red sage) protect against acute kidney injury
Researchers from the
Medical School of Nanjing University in China looked at whether red sage (
Salvia miltiorrhiza) could be useful in the treatment of acute kidney injury. They published their findings in
The American Journal of Chinese Medicine.
- Red sage is a commonly used herbal medicine in China and other Asian countries.
- Earlier studies have shown that tanshinone IIA, a diterpene extracted from red sage, has pleiotropic effects on many disease treatments because of its anti-toxicity, anti-inflammatory, anti-oxidative stress, and antifibrosis activities.
- However, its effect on acute kidney injury has not been fully studied.
- In this study, researchers examined the effect of tanshinone IIA on acute kidney injury in mice.
- Acute kidney injury was induced by folic acid.
- They found that treatment with tanshinone IIA can result in improved kidney function in folic acid-induced kidney injury mice.
- In the acute phase of kidney injury, tanshinone IIA treatment reduced renal tubular epithelial injury.
- In addition, treatment with tanshinone IIA led to increased proliferating cell nuclear antigen (PCNA) expression and decreased inflammatory cells infiltration as well as chemokine expression.
- This effect suggested that tanshinone IIA promoted renal repair following acute kidney injury and inhibited the local inflammatory response in the injured kidney.
- As a result, long-term fibrosis in the injured kidney diminished, which was characterized by less accumulation of fibronectin and collagen I in tubulointerstitium.
In conclusion, these results indicated that tanshinone IIA may be used as a natural medicine for the treatment of acute kidney injury.
