nucleotide phosphodiesterase), prostaglandin E1 and sodium butyrate agents on neuroblastoma cells in culture.[3]Elevated

levels of SA induces two-stage urinary bladder carcinogenesis in rats.[2]sodium L-ascorbate in combination with collagenogenesis

inhibitors is used to treat dermal scars and keloids.[1]

•to study its effect on production of collagen and elastic fibers in fibroblasts cultures derived from normal human skin and dermal fat[1]
