Background: Many diabetic patients use herbal medicines in addition to their mainstream treatments. Plants contain a well-known and unknown set of compounds that may exacerbate or improve diabetes complications. Thus, the side effects of these herbs should be known before prescribing. The aim of the study is to investigate the effects of hydroalcoholic extract of Securigera securidaca (L.) Degen & Dorfl (S. securidaca) seed (HESS) on angiogenesis/anti-angiogenesis balance in Streptozotocin (STZ)-induced diabetic rats, alone and in combination with glibenclamide.
Methods: The groups involved in this animal study included diabetic and healthy control groups, groups treated with three doses of HESS, group treated with glibenclamide, and groups received combination therapy. Serum samples were taken and analyzed for the levels of angiogenic/ anti-angiogenic biomarkers.
Results: Induction of diabetes increased serum levels of angiogenic agents and decreased circulating anti-angiogenic factors. The herbal extract, even with the highest dose, had little effects on the blood levels of the tested biomarkers except with TGF-β. Glibenclamide was more effective than the highest dose of HESS in preventing the increase in serum levels of angiogenic factors and in inhibiting the decrease in anti-angiogenic agents in diabetic rats. Combination therapy with the highest dose of HESS partly enhanced the glibenclamide effects.
Conclusions: Although glibenclamide was more effective than the highest dose of HESS used in this study in preventing changes in serum concentrations of angiogenic/ anti-angiogenic biomarkers in the diabetic animals, this study show that S. securidaca has no side effects on diabetes complications caused by vascular disorders and neovascularization, and still it can be used as a herbal supplement with the standard drug.
