uncaria sinensis/グルタチオン

Previously, we revealed that oral administrations of Choto-san, a Kampo formula, and the hooks and stems of Uncaria sinensis Haviland (Rubiaceae), a medicinal plant comprising Choto-san, enhanced superoxide anion and hydroxyl radical scavenging activities in the hippocampus, and prevented delayed

BACKGROUND While the hook of Uncaria rhynchophylla (URH) is a traditional herb used in northeast Asia for the treatment of Parkinson's disease (PD)-like symptoms such as tremor, it has not been experimentally evaluated in a PD model. OBJECTIVE We investigated the effects of URH on 6-hydroxydapamine

Beta-amyloid peptide (Aβ), a major protein component of senile plaques, has been considered as a critical cause in the pathogenesis of Alzheimer's disease (AD). Modulation of the Aβ-induced neurotoxicity has emerged as a possible therapeutic approach to ameliorate the onset and progression of AD.

The stem with hooks of Uncaria rhynchophylla is a component herb of many traditional formulae for the treatment of neurodegenerative diseases. However, scientific evidence of the efficacy of Uncaria rhynchophylla in the treatment of Alzheimer's disease (AD) in animal models is lacking. Thus, in the

Isorhynchophylline (IRN), an alkaloid isolated from Uncaria rhynchophylla, has been reported to improve cognitive impairment induced by beta-amyloid in rats. However, whether IRN could also ameliorate the D-galactose (D-gal)-induced mouse memory deficits is still not clear. In the present study, we

OBJECTIVE The present work intended to study the antitumoral and antioxidant effects of Uncaria tomentosa (UT) hydroalcoholic extract in the Walker-256 cancer model. METHODS Walker-256 cells were subcutaneously inoculated in the pelvic limb of male Wistar rats. Daily gavage with UT extract (10, 50

The activity and gene expression of strictosidine-related enzymes in Uncaria tomentosa root cultures exposed to oxidative stress were studied. Elicitation with 0.2 mM hydrogen peroxide (H2 O2 ) or a combination of 0.8 mM buthionine sulfoximine and 0.2 mM jasmonic acid (BSO-JA) increased peroxidase
