RESUMO

The perennial plant Echinops spinosus (ES) grows in the Hail area of Saudi Arabia, and its traditional formulations are often employed in folk medicine. The goal of this study is to identify the active components present in Hail Echinops spinosus and to investigate the anti-diabetic properties of both ES total extract (ESTE) and its high flavonoids fraction (ESHFF) in experimental diabetes induced by streptozotocin (STZ) injection in rats. Forty-two rats were divided into six groups. Diabetes was induced using STZ (55 mg/kg). Seven days after STZ administration, the diabetic animals were treated daily with ESTE, ESHFF, or metformin (MET) as a standard anti-diabetic drug for 28 days. Blood and tissues samples were collected for biochemical, molecular, and histological investigations. Both ESTE and ESHFF demonstrated anti-diabetic properties, as evidenced by lowering glucose levels and increasing the levels of insulin, insulin receptor expression rate, and glycogen synthesis. Additionally, ESTE as well as ESHFF alleviated diabetic complications in the kidneys and liver by decreasing oxidative stress, modulating inflammatory mediators, and suppressing the apoptotic cascade along with correcting diabetic dyslipidemia. It could be deduced that Hail ES extracts could play a role in the treatment of type 2 diabetes and diabetes-related lesions as well as oxidative damage in hepatic and renal tissues.

RESUMO

OBJECTIVE: The chemo-preventative and therapeutic properties of selenium nanoparticles (SeNPs) have been documented over recent decades and suggest the potential uses of SeNPs in medicine. Biogenic SeNPs have higher biocompatibility and stability than chemically synthesized nanoparticles, which enhances their medical applications, especially in the field of cancer therapy. This study evaluated the potential of green-synthetized SeNPs by using berberine (Ber) as an antitumor agent and elucidated the mechanism by which these molecules combat Ehrlich solid tumors (ESTs). METHODS: SeNPs containing Ber (SeNPs-Ber) were synthesized using Ber and Na2SeO3 and characterized with Fourier transform infrared spectroscopy. Sixty male Swiss albino mice were then acclimatized for one week, injected with Ehrlich ascites tumor cells, and divided into four groups: EST, EST + cisplatin (5 mg/kg), EST + Ber (20 mg/kg), and EST + SeNPs-Ber (0.5 mg/kg). At the end of a 16-day observation period, 12 mice from each group were euthanized to analyze differences in the body weight, tumor size, gene expression, and oxidative stress markers in the four groups. Three mice from each group were kept alive to compare the survival rates. RESULTS: Treatment with SeNPs-Ber significantly improved the survival rate and decreased the body weight and tumor size, compared to the EST group. SeNPs-Ber reduced oxidative stress in tumor tissue, as indicated by a decrease in the lipid peroxidation and nitric oxide levels and an increase in the glutathione levels. Moreover, SeNPs-Ber activated an apoptotic cascade in the tumor cells by downregulating the B-cell lymphoma 2 (Bcl-2) expression rate and upregulating the Bcl-2-associated X protein and caspase-3 expression rates. SeNPs-Ber also considerably improved the histopathological alterations in the developed tumor tissue, compared to the EST group. CONCLUSION: Our study provides a new insight into the potential role of green-synthesized SeNPs by using Ber as a promising anticancer agent, these molecules could be used alone or as supplementary medication during chemotherapy.

RESUMO

Plant derived phytochemical therapy is a bright candidate for treatment of diabetes and its associated complications. Ocimum baslicum is used as an anti-diabetic traditional medicine. Hence, the present study investigated the effect of Hail Ocimum extract (HOE) and its total flavonoids (HOETF) against hepatorenal damage in experimental diabetes induced by high-fat diet (HFD) and injection of streptozotocin (STZ) in rats. Diabetic animals were co-treated daily with HOE, HOETF or metformin (MET) as a standard anti-diabetic drug for four weeks. Compared to controls, HFD/STZ-treatment lead to significant increases in fasting blood glucose, insulin and HOMA-IR levels. Furthermore, diabetic rats had elevated hepatic (ALT and ALP) and kidney functions (urea and creatinine) biomarkers together with disturbed lipid profile and decreased PPAR-γ gene expression. Higher levels of hepatic and renal LPO and NO paralleled with lower levels of GSH and activities of antioxidant enzymes (SOD, CAT, GPx and GR) after HFD/STZ treatment. Additionally, noteworthy inflammatory and apoptotic responses were evident in both organs of diabetic rats as witnessed by augmented levels of TNF-α, IL-1b and Bax levels with declined levels of Bcl-2. Moreover, histological examination of hepatic, renal and pancreatic tissues validated the biochemical findings. On contrary, co-treatment of diabetic animals with HOE or HOETF could decrease glucose and insulin levels together with improvement of lipid markers and alleviation of hepatorenal dysfunction, oxidative injury, inflammatory and apoptotic events. Conclusively, HOE or HOETF could be a promising complementary therapeutic option for the management of diabetic hepatorenal complication owing to their antioxidant, anti-inflammatory; anti-apoptotic properties.
