12.Pyridazinone derivatives have considerable kinds of biological activities such as those cardiotonic,platelet aggregation inhibitory,anti-inflammatory,aldose reductase inhibitory,antifungal and so on.
14.Their biological activity is generally attributable to inhibition of NADH: ubiquinone oxidoreductase activity and thereby mitochondrial respiration.
18.KGF can specifically stimulate the epithelial mitogenesis and regulate the interaction of mesenchyma and epithelia,so it has broad biological functions.
19.With the development of biotechnics, especially the tissue engineering, the biological application of wool keratin attracts more and more researcher's attention.
20.The monosaccharide are made up of rhamnose, glucose, mannitose, galactose and xylose.It offers foundation for boosting biological activities by hydrolyzing saponins.
