Applications
1. Immune system diseases Hanfanganin can significantly inhibit the development of arthritis and its effect is stronger than that of aspirin, so it can be used in the treatment of rheumatoid arthritis.
2. Cardiovascular system diseases Hanbanzin not only has calcium antagonistic effect, can inhibit T-type and L-type calcium channels in ventricular myocytes, but also interacts with M receptors and can block calcium-activated potassium channels, which is a treatment method for paroxysmal supraventricular tachycardia.
3. Digestive system Hanbanzin A has a role in protecting hepatocytes and anti-liver fibrosis.
4. Ophthalmic diseases Hanbanzin A is used in the treatment of eye inflammation, including uveitis, keratitis and its resulting retinopathy.
It can reduce the apoptosis and proliferation of renal tubular epithelial cells, protect kidney function, protect against acute ischemia-reperfusion kidney injury, significantly reduce serum creatinine and urea nitrogen levels, improve glomerular filtration rate and renal plasma flow, and delay the development of glomerulosclerosis.
