Brain tissue transplant in middle-aged animals survives better if animal is supplemented with blueberry extract

June 03, 2005

A number of studies show that blueberry extract actually reverses aging and improves the health of the hippocampus, a key area of the brain for memory and learning. Improving the health of the hippocampus improves memory and cognitive function. Brain tissue transplantation is being explored as a potential treatment to replace dead and dying tissue in the brain after an accident or due to neurodegenerative diseases (such as Alzheimer's and Parkinsons's diseases). However, the transplanted brain tissue survives poorly as age increases. In this study, young and middle aged animals received hippocampal tissue transplants. Predictably, the tissue transplant didn't survive as well or organize itself as well in the middle-aged versus the young animals. Some of the animals were supplemented with a blueberry extract and some weren't. When middle-aged animals were placed on the Blueberry extract the grafted tissue's growth (and therefore survival) significantly improved and the tissue organized itself as well as the grafts in the young animals. Factors in Blueberry extract have a significant impact on the wellness of this very important brain region and for restoring memory function. The study was performed at the Department of Neuroscience and the Center on Aging, Medical University of South Carolina, Charleston, SC, and is published in the current issue of the journal Cell Transplantation, the Journal of the Cell Transplantation Society.

Green Tea Polyphenols protect and nurture the skin

Plant extracts have been widely used topically for wound-healing, anti-aging, and disease treatments. These plants and ingredients include Grape Seed, Green tea, Rosemary, Soy, and Aloe Vera (among others). These plants share the common characteristic of having their own particular polyphenols. These polyphenols inhibit free radical oxidation, bacterial (biological) activity, and initiate healing. The Green Tea Catechins have a number of promising properties. Studies show that the Green Tea Polyphenols have an impact on decreasing the risk of skin cancers, heal our skin, and have antioxidant, antiinflammatory activity. The research review was performed at the Department of Oral Biology and Maxillofacial Pathology, School of Dentistry, Medical College of Georgia, Augusta, Georgia, and is published in the June 2005 issue of the Journal of the American Academy of Dermatology.
