Pharmacological effects of Rhizoma Drynariae

1. According to the research of Zhou Tongshui et al. from China Pharmaceutical University, oral administration of water decoction of Quercus ferns rhizomes (20g/kg, 30g/kg) and naringin (equivalent to 20g/kg of the original drug) promoted the healing of bone injuries in experimental rats.

2. Oral administration of 7.5-50g/kg of Drynaria decoction can stimulate the compensatory proliferation of osteoarticular chondrocytes in rats with experimental arthritis, and can partially improve the degeneration of articular cartilage caused by changes in mechanical stress lines, thereby reducing the incidence of osteoarticular lesions.

3. The dihydroflavonoid glycosides of Drynaria fortunei can increase the beating frequency of rat and neonatal cardiomyocytes cultured in vitro, make the contraction stronger, and have a pacemaker effect on cardiomyocytes. Its mechanism of action may be similar to that of a β-receptor agonist.

4. Oral administration of 0.8 ml/kg of Drynaria fortunei decoction (100%) can significantly prevent the increase of serum cholesterol and triglycerides in experimental hyperlipidemia rabbits, and prevent the formation of atherosclerotic plaques in the aortic wall. 5. Guinea pig experiments suggest that the combined use of Drynaria fortunei decoction and kanamycin can reduce the toxic effects of kanamycin on the cochlea, but cannot control the development of toxic deafness after drug withdrawal.
