Rheumatoid arthritis is an autoimmune disease that causes chronic inflammatory in the joints and causes fatal disorders in the joints. There are various inflammatory factors in the joint of patients with rheumatoid arthritis. The pro-inflammatory cytokines TNF-α, IL-6 and Nitric Oxide (NO) are the major causes and play an important role in the immune system. However, if it is overproduced, it will cause an inflammatory reaction. Thus, it is important to regulate TNF-α, IL-6 and NO.
In this study, we examined the effect of inhibiting inflammatory by using 628 kinds of natural products in the RAW 264.7 cells induced by LPS. As a result of screening, Cassia angustifolia Vahl was selected. Cassia angustifolia Vahl is widely used as laxatives. It is toxic to humans and can be used as a small amount of drug, and can not be used as a raw material for food. Therefore, several biological experiments were conducted to confirm the inhibitory effect of Cassia angustifolia Vahl methanol extract (CAM) on rheumatoid factor. The inflammatory response of RAW 264.7 cells was induced by LPS and the inhibitory effect of inflammatory factors was confirmed by MTT reduction assay, NO production assay, Morphological assay, ELISA assay.
As a result, inhibition of rheumatoid arthritis related factors of Cassia angustifolia Vahl in LPS induced RAW 264.7 cells was confirmed. Thus, Cassia angustifolia Vahl was given to the possibility to a natural drug material.
