The Preparation of Hyaluronic Acid Nanoparticles from Aspicilia lichens Using Bifido Bacteria for Help in the Treatment of Diabetes in Rats In Vivo.

Many common herbs and spices are claimed to have blood sugar lowering properties that make them useful for people with or at high risk of diabetes. The main of compounds of kiwifruit (Actinidia deliciosa), rhubarb (Rheum ribes), membrane inner of egg shell, wool of sheep, human fingernail (unguis), hyaluronic acid produced by the Bifidobacterium, and usnic acid of Aspicilia lichen were extracted by different methods. All compounds of the extract were divided into five groups. We used variables such as pH, different compounds, concentration, number of injections, and blood glucose monitoring in different situations. Our study, extracts changed to nanoform. The extract compounds and nanoparticles were analyzed by gas chromatography mass spectroscopy, Fourier transform infrared spectroscopy, hydrogen-1 nuclear magnetic resonance, and scanning electron microscope. The average size of the nanoparticles was found to be 55 nm. Five groups of nanoparticles were injected into rats, and they reduced their blood glucose levels significantly (statistical significance was declared at p < 0.05). The synthesized hyaluronic acid helped to treat diabetes in rats.
