Descriptions:
Ginsenoside Rd (Rd), a saponin isolated from the roots of panax notoginseng, Rd has immunological adjuvant activity, and elicits a Th1 and Th2 immune response by regulating production and gene expression of Th1 cytokines and Th2 cytokines.[1]
Ginsenoside-Rd could play a crucial role in enhancing the defence system to counteract the aging process, through regulation of the GSH/GSSG redox status, decreasing in the superoxide dismutase (SOD) and catalase activity in old SAM.[2]
Ginsenoside-Rd treatment shows attenuation of hypertensive cerebrovascular remodeling, the underlying mechanism might be associated with inhibitory effects of ginsenoside-Rd on voltage-independent Ca 2+ entry and BAVSMC proliferation, but not with VDCC-mediated Ca 2+ entry.[3]
Ginsenoside Rd, a -type steroid extracted from , has exhibited an encouraging neuroprotective efficacy in both laboratory and clinical studies, could be as a neuroprotective agent for acute .[4]
Ginsenoside Rd can enhance the proliferation but not affect the differentiation of neural stem cells in vivo and in vitro.[5]
Ginsenoside Rd prevents glutamate-induced apoptosis in rat cortical neurons and may be the potential of voltage-independent Cachannel blockers as new neuroprotective drugs for the prevention of neuronal apoptosis and death induced by cerebral ischaemia.[6]
