REVIEW
Rui Jiao, Yingxia Liu, Hao Gao, Jia Xiao, Kwok Fai So
Oxidative stress has been increasingly recognized as a major contributing factor in a variety of human diseases, from inflammation to cancer. Although certain parts of signaling pathways are still under investigation, detailed molecular mechanisms for the induction of diseases have been elucidated, especially the link between excessive oxygen reactive species (ROS) damage and tumorigenesis. Emerging evidence suggests anti-oxidant therapy can play a key role in treating those diseases. Among potential drug resources, plant polysaccharides are natural anti-oxidant constituents important for human health because of their long history in ethnopharmacology, wide availability and few side effects upon consumption...

Adult neurogenesis has received much attention due to its potential role in neurological or psychiatric disorders such as Alzheimer's disease. In the present study, we examined whether spinosin, a C-glycoside flavonoid from the seeds of Zizyphus jujuba var. spinosa, affects cognitive performance and adult hippocampal neurogenesis in normal naïve mice. The subchronic administration of spinosin (5mg/kg) for 14days significantly increased the latency time in the passive avoidance task. Doublecortin and 5-bromo-2-deoxyuridine immunostaining revealed that the subchronic administration of spinosin (5mg/kg) significantly increased the proliferation and survival of neuronal cells and the number of immature neurons in the hippocampal dentate gyrus region...

An allergy may sometimes be very dangerous and one of the main factors responsible for allergy is the complement system which can lead to a life-threatening reaction called anaphylaxis. Cycloxygenase-1 (COX-1), Cycloxygenase-2 (COX-2) and 5-Lipoxygenase (5-LOX) trigger allergic and inflammatory reactions. A number of anti-allergic synthetic drugs are available but are costly and show many side effects. Hence, the ancient traditional system of medication mentioned in Ayurveda finds an edge over various synthetic drugs...
