SummaryIntroduction: The liver is involved in the metabolism of xenobiotics and their metabolites and it is vulnerable to oxidative damage. Hyperglycaemia is highly implicated in the progression of diabetes mellitus, and adversely affects the liver. Though, conventional hypoglycaemic drugs may be effective in reducing blood glucose, they do not appear to be effective in attenuating the progression of diabetes and its complications.Objective: This study evaluated the ameliorative effects of Anchomanes difformis on hyperglycaemia and hepatic injuries in type 2 diabetes.Methods: Type 2 diabetes was induced in male Wistar rats with a single intraperitoneal injection of streptozotocin (40 mg/kg BW) after two weeks of fructose (10%) administration. Aqueous extract of A. difformis (200 and 400 mg/kg BW) and glibenclamide (5 mg/kg BW) were administered orally for six weeks. Blood glucose concentrations were measured. Serum levels of liver dysfunction markers (ALT, AST, and ALP), total cholesterol, triglycerides, HDL- and LDL-cholesterol were investigated. Total protein, albumin, and globulin were also assessed. Antioxidant parameters: ORAC, GSH, GSSG, SOD, CAT and FRAP were evaluated in the liver while ORAC, FRAP and lipid peroxidation were determined in the serum. Histological examination of the liver tissue was carried out.Results: Treatment with aqueous extract of A. difformis significantly (p<0.05) reduced blood glucose and reversed steatosis in the diabetic-treated rats. The antioxidant status of diabetic-treated rats was significantly (p<0.05) improved. Serum levels of liver dysfunction markers were significantly (p<0.05) reduced in diabetic-treated rats.Conclusion: The findings in this study revealed that 400 mg/kgBW Anchomanes difformis was more effective than 200 mg/kg BW in ameliorating diabetes-induced hepatopathy, however, both doses of Anchomanes difformis demonstrated more antidiabetic ability than glibenclamide. Anchomanes difformis may be a novel and potential therapeutic agent in the management of diabetes and resulted hepatic injuries.

The current study involved collecting 225 samples of different age groups and from different clinical sources (burns and wounds). Selective and differential media, Microscopic Examination, Biochemical test, IMVIC tests, and Vitek 2 system were used to identify the bacterial species. The results showed that the bacterial isolates were distributed on Staphylococcus aureus, Pseudomonas aeruginosa, Staphylococcus epidermidis, Klebsiella pneumoniae, Escherichia coli and Proteus mirabilis. All isolates were multidrug-resistant to 12 antibiotics from different classes and according to the susceptibility test, isolate distinction in 2 groups (75 %) of MDR isolates were resistant to (5-9) antibiotics, while (25 %) were susceptible. Zinc Oxide nanoparticles synthesized was done by a green method with Zinc acetate dehydrate as a precursor and aqueous extract of Camellia sinensisas a reducing agent, color-changing to pale-white was an indication of the formation of ZnONPs. The average size and shape of the nanoparticles were detected by using Atomic Force Microscopy (AFM) which was 40 nm with a spherical shape. Scanning Electron Microscopy (SEM) showed the ZnO NPs have spherical, radial, and cylindrical structures. The wavelength range was measured by Ultraviolet-visible spectroscopy (UV-Vis) for monitoring the formation of the nanoparticles, which showed a sharp peak at 325 nm. The average crystallite size of ZnONPs was estimated using Debye Scherrer’s formula were 20-40nm by using X-ray Diffraction (XRD). Fourier-transform infrared spectroscopy (FT-IR) spectra have been used for ZnONPs to detect the functional groups found in the synthesis process via green tea extract. Keyword: ZnO NPs.

The aim of this article describes the application of green tea aqueous extract as an eco-friendly corrosion inhibitor for two Cu-Ni alloys in 3.5% NaCl solution. This ability has been studied by using electrochemical techniques (i.e. PDP, CT and EIS), IR spectroscopy measurements and the surface analysis technique (i.e. SEM/EDX). This ability was compared with it's of a commercial cooling water (green water). The results show that tested extract exhibited a good ability to decrease the corrosion rate of alloys in 3.5% NaCl solution.The inhibition efficiency of the green water and green tea extract inhibitors increased with increasing the concentration and decreased with increasing the temperature. The inhibition efficiency of two Cu-Ni alloys which reaching ̴ 91.5% and ̴ 93.9% with 50 % green tea aqueous extract for Cu-10 Ni and Cu-30 Ni alloy, respectively. Electrochemical impedance showed that the change in charge transfer resistance (Rct) and double layer capacity (Cdl) which adsorbed on the alloy surface. Adsorption of the inhibitors gives a good fit to Langmuir isotherm model. Some thermodynamic parameters of activation and adsorption processes were also determined and discussed. Surface examination studies by SEM and EDX confirm the presence of protective film on the alloy surface. In the present study, we investigated the corrosion of the Cu-Ni (cupronickel) alloys in 3.5 % NaCl environment to simulate the seawater desalination plants conditions. Therefore, the future studies can be focused on the development of polymeric compounds used as self- healing or production of new natural corrosion inhibitors especially recommended the waste product of green tea.
