Abstract: Introduction: Seeds of Securigera securidaca (L.) Degen & Dorfl are rich in flavonoids and phenolic acids which have potent biological effects. The current study was undertaken to evaluate the effects of hydroalcoholic extract of S. securidaca seeds (HESS) alone, and in combination with a standard drug, glibenclamide (GB) on paraoxonase1 (PON1) activity, lipid profile and peroxidation, and cardiovascular risk indices in streptozotocin (STZ) induced diabetic rats. Methods: Forty-eight male Wistar rats were randomly ided into eight equal groups and orally treated with various doses of HESS (100, 200, 400 mg/kg) alone and in combination with GB (5 mg/kg) for 35 consecutive days. After blood s ling, lipid profile including triglyceride (TG), cholesterol, high, low and very low-density lipoprotein-cholesterol (HDL-C, LDL-C, and VLDL-C), as well as serum PON1 activity, were assessed. Malondialdehyde (MDA), tumor necrosis factor-alpha (TNF-α), and high-sensitivity C-reactive protein (hs-CRP) levels were also measured. Several indices of cardiovascular risk and the correlation between PON1 activity and these indices were calculated based on the obtained results from the lipid profile. Results: Induction of diabetes could dramatically alter all of the parameters mentioned above, and the lower dose of HESS (100 mg/kg) was not effective in restoring the parameters. However, the higher doses (200 and 400 mg/kg) alone and in combination with GB could significantly improve lipid profile, restore PON1 activity, and decrease cardiovascular risk indices, MDA, as well. However, neither HESS nor GB could significantly reduce TNF-α and hs-CRP. A significant negative correlation also was detected between PON1 activity and cardiovascular risk indices. Conclusion: conclusively, HESS can be considered as a potent antihyperlipidemic agent with remarkable cardioprotective effects and can potentiate the antidiabetic effects of GB.

Abstract: Undesired effects of synthetic antidiabetic agents have made researchers to seek for safer and healthier resources. With this aspect, herbal materials have attracted substantial research interest and are being extensively investigated. Considering that herb-drug interactions can be a double-edged sword presenting both risks and benefits, investigation of such interactions is greatly in demand. to investigate possible beneficial effects of hydroalcoholic extract of SecurigeraSecuridaca seed (HESS) on antioxidant capacity, fibroblast growth factor 21 (FGF21) and insulin resistance in Streptozotocin (STZ)-induced diabetic rats, alone and in combination with glibenclamide. Forty male Wistar rats were randomly ided in to eight equal groups including healthy and diabetic controls and six treated groups with a various doses of HESS alone and in combination with glibenclamide, for 35 consecutive days. Serum s les were taken and analyzed for biochemical profile, HOMA indexes, FGF21, oxidative/nitrosative stress and inflammatory biomarkers as compared with the controls. Moreover, total phenolic and flavonoid contents of herbal extract were assessed. The herbal extract was found to be rich in flavonoid and phenolic components. Both of glibenclamide and the HESS decreased glucose and insulin resistance, as well as increased body weight and insulin sensitivity. Moreover, the extract could mitigate oxidative/nitrosative stress and inflammation dose-dependently, however, the standard drug was less effective than HESS. Induction of diabetes increased FGF21 levels and both of the treatments could reduce its contents, however, glibenclamide was more effective than HESS. The results clearly show that there is no contradiction between HESS and glibenclamide. Moreover, the herbal extract could augment antioxidant and anti-inflammatory properties of the standard drug.
