Aging is also associated with an increase in oxidative stress[2]. Considering that older adults are already at risk for oxidant stress, the additional metabolic perturbations of obesity aggravated the susceptibility to oxidant stress. Modulating age-related oxidative stress via dietary interventions could reduce free radical production and significantly improve health in aging.展开更多

Methods： Subacute aging rats model were established by injection with D-gal solution. Points Shenshu （BL 23） were treated with moxibustion in treatment group, contrasting with a model group and a normal group. Enzyme-Linked Immunosorbent Assays（ELISA） was used for the level of telomerase activity in liver tissues, and In Situ Hybridization（ISH） was used for the condition of expression of telomerase genes in liver tissues. Results： The level of telomerase activity in the aging model group was obviously lower than that in normal control group （P〈0.01）, the level in moxibustion group was obviously higher than that in model group（P〈0.05）. In comparison with normal rats, the positive-expressed areas and photodensity of telomerase genes in aging model group were all significantly lower （P〈0.01, P〈0.01）, and the positive-expressed areas in moxibustion group was significantly higher than that in model group （P〈0.01）. Conclusions： Moxibustion could regulate telomerase activity of senile rats, hence delaying aging.展开更多
We induced ischemic brain injury in aging rats to examine the effects of varying doses of propofol on hippocampal activities of acetylcholinesterase, N-methyI-D-aspartate receptors, and y-aminobutyric acid receptors. ...We induced ischemic brain injury in aging rats to examine the effects of varying doses of propofol on hippocampal activities of acetylcholinesterase, N-methyI-D-aspartate receptors, and y-aminobutyric acid receptors. Propofol exhibited no obvious impact on acetylcholinesterase activity, but directly activated the y-aminobutyric acid receptor. The neuroprotective function of propofol on the hippocampus of aging rats following cerebral ischemic injury may be related to altered activities of y-aminobutyric acid receptors and N-methyI-D-aspartate receptors.展开更多
