Background: Nerium oleander L. is ethnopharmacologically used for diabetes. Our aim was to investigate the ameliorative effects of ethanolic Nerium flower extract (NFE) in STZ-induced diabetic rats. Methods: Seven random groups including control group, NFE group (50 mg/kg), diabetic group, glibenclamide group and NFE treated groups (25 mg/kg, 75 mg/kg, and 225 mg/kg) were composed of forty-nine rats. Blood glucose level, glycated hemoglobin (HbA1c), insulin level, liver damage parameters and lipid profile parameters were investigated. Antioxidant defense system enzyme activities and reduced gl ...Более
Many lichen secondary metabolites contributed to the field of pharmacology as an active ingredient of different drugs for years. In the present study, we aimed to test the anticancer activity of olivetoric acid (OA), which we isolated from Pseudevernia furfuracea (L.) Zopf in human hepatocellular carcinoma cells (HepG2). In addition, we used non-tumoral human liver cells (THLE2) to test the level of side effects of OA in vitro. For this purpose, cytotoxic (apoptotic and necrotic), oxidant, genotoxic activities and expression levels of apoptotic genes caused by different concentrations (12.5-40 ...Более
In this study, acetone and water extracts obtained from edible mushrooms, Rhizopogon luteolus Fr. and Rh. roseolus (Corda) Th. Fr., containing important bioactive components were used. Total antioxidant capacity (TAC) and total oxidative stress (TOS) levels were examined on human peripheral lymphocyte culture treated with the respective extracts. Levels of genetic damage and cytotoxic effects of the respective extracts on lymphocytes were also tested. In general, when TAC levels of the extracts on cells were examined, a concentration-dependent increase was observed; a negative correlation was ...Более
The potential human health risks of some toxic/harmful elements related to the consumption of Pseudevernia furfuracea (L.) Zopf. were investigated. The toxic/harmful elements (cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb), manganese (Mn), nickel (Ni), and zinc (Zn)) were determined in P. furfuracea. According to the analysis result, the maximum (max.) toxic/harmful element value was 62 +/- 3.1 mg/kg for Mn and minimum (min.) value was 0.19 +/- 0.01 mg/kg for Cd. The estimated daily exposure doses (EDEXDs) for men, women and children were dietary (bread) > dietary (tea) > dermal. For diet ...Более
Natural mushrooms are one of the important elements of the ecosystem. It has been preferred by people from past to present because of its nutritional and medicinal potentials. In this study, antioxidant, oxidant and antimicrobial potential of Trametes hirsuta (Wulfen) Lloyd has been determined. In addition, phenolic compounds in its fruiting body have been scanned. The antioxidant and oxidant potential was determined using Rel Assay kits. Antimicrobial potential was determined using the agar dilution method. Phenolic contents were scanned on the HPLC device. As a result of the studies, the pre ...Более
Background Liver has an important role in the initiation and progression of multiple organ failure that occurs in sepsis. Many natural active substances can be used to reduce the liver injury caused by sepsis. For this aim, the effects of myricetin and apigenin on mice model of acute liver injury was evaluated in this study. Methods and results Thirty-six mice were randomly divided into six groups as; control, lipopolysaccharide (LPS) (5 mg/kg), LPS myricetin (100 mg/kg), LPS myricetin (200 mg/kg), LPS apigenin (100 mg/kg), and LPS apigenin (200 mg/kg) groups. Myricetin and apigenin were admin ...Более
In the present study, cytotoxic (apoptotic and necrotic), antioxidant, prooxidant, genotoxic, and apoptosis-related genes expression modulatory effects of physodic acid (PA) isolated from Pseudevernia furfuracea on cancerous (HepG2) and healthy (THLE2) human liver cells were evaluated. Cytotoxic effects PA obtained from P. furfuracea on HepG2 and THLE2 cells were tested via MTT and LDH analyses. In order to determine genotoxic effect of PA, 8-OH-dG levels in the cells were measured. In addition, apoptotic or necrotic effects of PA on the hepatic cells were determined by qRT-PCR analysis. Cytot ...Более
