Worldwide, 1.5 to 2 million new cases occur each year .The histological study of liver tissue white laboratory mice (Mus musculus) infected with L. major a showed The presence severe steatosis hepatocytes Hepatocyte deg...

Oral administration of the perilla leaf extract (PLE) to mice inhibits inflammation, allergic response, and tumor necrosis factor-alpha production. We also found that PLE suppressed the tumor necrosis factor-alpha (TNF-alpha) production in vitro. Using the inhibitory activity of TNF-alpha production in vitro as the index for isolation, we searched the active constituents from PLE and isolated l...

The expression of endothelial cell (EC) adhesion molecules involved in leukocyte-vessel wall interactions is suppressed in malignancies. In the present study, we investigated in vivo the regulation of leukocyte-vessel wall interactions by the presence of a tumor. By means of intravital microscopy, tumor necrosis factor alpha-stimulated leukocyte-vessel wall interactions were studied in ear skin...
