functions and applications

1. kaempferol was found to be active in promoting opossum kidney cell growth . kaempferol stimulates kidney cells proliferation and increases secretion of bone growth factor . kaempferol may serve to stimulate kidney repair and up-regulate bone formation and may be useful in treating chronic kidney disease and osteoporosis .

2. kaempferol can inhibit the apoptosis induced by h202 in neonatal rat cardionyocytes . the protective effects could be related to their antiocidant activity and its ability to regulate the expression of bcl-2 , bax ,caspase-3 protein .

3. kaempferol is a blocker of voltagegated potassium channels in pyramidal neurons of rat hippocampus . the electrophysiological effects of kaempferol may be one mechanism of its protective effects on rat hippocampal neurons in acutely transient hypoxia .

4. kaempferol owe to the strong antioxidant properties , can scavenge superfluous superoxide free radicals in human body , preventing dna and cells from oxidative damage . it show pharmacological effects in anti-tumour ,anti-inflammation and anti-senility ,etc.

5. kaempferol has the effect of anti-epilepsy , antispasmodic ,anthelone , antiulcer ,choleretic, diuretic activity and relieving cough .
