In Vivo Type 2 Diabetes and Wound-Healing Effects of Antioxidant Gold Nanoparticles Synthesized Using the Insulin Plant Chamaecostus cuspidatus in Albino Rats.

Background: Gold nanoparticles are known for their many applications in the fields of therapeutics and diagnosis.

Methods: This article focuses mainly on the green method of synthesizing gold nanoparticles by using the leaf powder extract of the insulin plant Chamaecostus cuspidatus and on the characterization of developed plant-mediated synthesis of gold nanoparticles. Furthermore, we investigated the free-radical scavenging activity of green-synthesized gold nanoparticles.

Results: The free radicals were exhibited in a dose-dependent manner. The 50% inhibition of free radicals by gold nanoparticles showed that it was similar to that of the standard inhibition. Toxicity studies generally examine changes in blood serum chemistry and cell populations in tissue morphology through histologic analysis without inducing any lethal effects in the mouse model, thereby accomplishing sustained control over the progression of diabetes mellitus, which plays a leading role in vascular complications in patients. The treatment by gold nanoparticles of the mice with diabetes for a period of 21 days restored their blood glucose, glycogen and insulin levels.

Conclusions: The use of gold nanoparticles as antidiabetes materials has been achieved. Further studies are required before gold nanoparticle-based drugs are more widely used.
