Low-dose gamma-irradiation inhibits IL-6 secretion from human lung fibroblasts that promotes bronchial epithelial cell transformation by cigarette-smoke carcinogen.

abstract：:In recent years, considerable emphasis has been placed on identifying new cancer chemopreventive agents which could be useful for human populations. Silymarin, an anti-oxidant flavonoid isolated from artichoke, has been shown to possess significant activity against hepatotoxicity and other pharmacological and physiolo...

abstract：:High intake of red meat is associated with an increased risk of colon cancer. It has been suggested that fat from red meat is responsible, because high fat intake increases the concentration of cytotoxic lipids in the colon. Experimental studies have not unequivocally supported such a role for fat, however. Recently, ...
