Aim: To determine whether treatment with the stem cell stimulator Olimpiq® Stem×Cell prevents increase of retinal and renal vascular permeability in alloxan-induced diabetic rats. Materials and Methods: Two groups of Wistar rats were made diabetic by single intraperitoneal injection of Alloxan. The third, the control group, received vehicle alone. One diabetic group received Olimpiq® Stem×Cell treatment for 4 weeks. The permeability of the blood–retinal barrier (BRB) and renal vessels were measured by the extravasation of fluorescein–labeled bovine serum albumin. Results: Six weeks subsequently to Alloxan injection, significantly elevated the tissue fluorescence, the renal vascular leakage and BRB breakdown was demonstrated in the diabetic group, compared to the nondiabetic group. Olimpiq® Stem×Cell treatment significantly reduced the BRB breakdown, tissue fluorescence, and vascular leakage. Conclusion: Olimpiq® Stem×Cell would be a useful choice of treatment for complications associated with increased vascular permeability of diabetes, such as retinopathy or nephropathy.

Cancer is the second leading cause of death globally. Although, there are many different approaches to cancer treatment, they are often painful due to adverse side effects and are sometimes ineffective due to increasing resistance to classical anti-cancer drugs or radiation therapy. Targeting delayed/inhibited apoptosis is a major approach in cancer treatment and a highly active area of research. Plant derived natural compounds are of major interest due to their high bioavailability, safety, minimal side effects and, most importantly, cost effectiveness. Flavonoids have gained importance as anti-cancer agents and have shown great potential as cytotoxic anti-cancer agents promoting apoptosis in cancer cells. In this review, a summary of flavonoids and their effectiveness in cancer treatment targeting apoptosis has been discussed.
