(Natural News) Researchers from the National Yang-Ming University School of Medicine in Taiwan found that baicalein, a compound present in Chinese skullcap (Scutellaria baicalensis), can inhibit production of tumor necrosis factor-alpha (TNF-a) and regulate pro- and anti-apoptotic signaling elements. The study was published in The American Journal of Chinese Medicine.
- Chinese skullcap is used in traditional medicine to treat cardiovascular disease.
- Researchers looked at the efficacy of baicalein against lung injury brought about by myocardial ischemia and reperfusion (I/R). To induce myocardial I/R, a 40-minute occlusion on the left anterior descending coronary artery was made. This increased histological damage, as well as the wet-to-dry weight ratio of lungs.
- In addition, it also significantly increased terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL)-positive nuclei and caspase-3 activation, including serum and bronchoalveolar lavage fluid levels of TNF-a, interleukin-1-beta (IL-1B), and interleukin-6 (IL-6).
- In the study, the researchers injected mice with 3, 10, and 30 mg of baicalein per kilogram of body weight for 10 minutes before inducing myocardial I/R.
- Mice treated with baicalein exhibited reduced histological damage, wet-to-dry-weight ratio, and lung apoptosis.
- Baicalein also inhibited TNF-a, IL-1B, and IL-6 levels from increasing.
- It also improved Bcl-2 and decreased p53, Bax, and cytochrome c levels in the lungs.
The researchers concluded that baicalein can help with the symptoms of lung injury after being induced with myocardial I/R.
