Antihepatocarcinoma Effect of Portulaca oleracea L. in Mice by PI3K/Akt/mTOR and Nrf2/HO-1/NF-κB Pathway

Figure 4

Effects of Purslane on pathological changes of the liver tissues of NDEA-induced mice. Liver inflammatory cell count based on a five-point scoring system was performed to estimate the severity of leukocyte infiltration. The scoring system was as follows: 0: no cells, 1: a few cells, 2: a ring of cells with a thickness of 1 cell layer, 3: a ring of cells with a thickness of 2–4 cell layers, and 4: a ring of cells with a thickness of more than 4 cell layers.
