Protective effect of Xin Mai Jia ultrafiltration extract on human umbilical vein endothelial cell injury induced by hydrogen peroxide and the effect on the NO-cGMP signaling pathway.

The XMJ ultrafiltration extract significantly improved the morphological changes in the injured HUVECs. These properties significantly inhibited the H 2 O 2 -induced injury of HUVECs, which may be associated with the NO-cyclic guanosine monophosphate signaling pathway.

Cell-count and viability assessment in the study's cell samples was performed with Countstar (model not specified) during sample-quality assessment.
