"In diabetic rats Ginkgo biloba had a very good effect on the beta cells of Langerhans -- cells in the pancreas responsible for insulin secretion -- by creating a restorative effect similar to what we see in healthy non-diabetic rats," says Helal Fouad Hetta, PhD, a postdoctoral fellow and scientist in the UC Division of Digestive Diseases. Hetta is also on faculty at Egypt's Assiut University College of Medicine in the Department of Medical Microbiology and Immunology.
The study in animal models by an international team of 13 researchers was published in the journal Diabetes, Metabolic Syndrome and Obesity: Targets and Therapy and is available online. The first author on the research is Ahmed Saleh, PhD, Jazan University in Saudi Arabia.
Extracts - Ginkgo - Biloba - Medicine - Potency
"The extracts derived from Ginkgo biloba have been frequently used in traditional medicine and have been shown to exhibit antioxidant potency," says Hetta. "Magnetized water, which has been passed through a magnetic field, has also been reported to reduce blood glucose, improve antioxidant status and lipid profiles in diabetic rat models."
In this study, Type 2 Diabetes was induced by feeding rats a high-fat-diet for eight weeks followed by intra-peritoneal injection of a single low dose of streptozotocin, explains Hetta. Forty rats were randomly assigned to four groups: a non-diabetic control group and three diabetic groups. One diabetic group served as a positive control (diabetic), while the other two groups were orally administered with water extract of Ginkgo biloba leaves and magnetized water for four weeks, respectively.
Beta - Cells - Rats - Secretion - Ginkgo
The beta cells of diabetic rats are reduced and insulin secretion is curtailed. After having Ginkgo biloba and magnetized water added to their diets, the mass of the pancreatic beta cells and the amount of insulin in these cells was shown to increase markedly, almost back to normal...
