Background and Objectives: The excess consumption of fructose in the diet may cause metabolic syndrome, which is associated with an increased risk of kidney disease. There is limited data on probiotic treatment in high-fructose-induced metabolic syndrome. The present study aims to investigate whether the supplementation of Lactobacillus plantarum (L. plantarum) and Lactobacillus helveticus (L. helveticus) could provide an improving effect on the renal insulin signaling effectors, inflammatory parameters, and glucose transporters in fructose-fed rats. Materials and Methods: The model of metabolic syndrome in male Wistar rats was produced by fructose, which was given as 20% solution in drinking water for 15 weeks. L. plantarum and L. helveticus supplementations were given by gastric gavage from 10 to 15 weeks of age. Results: High-fructose consumption in rats reduced renal protein expressions of insulin receptor substrate (IRS)-1, protein kinase B (AKT), and endothelial nitric oxide synthase (eNOS), which were improved by L. plantarum and partially by L. helveticus supplementations. Dietary fructose-induced elevations in renal tissue levels of tumor necrosis factor α (TNF-α), interleukin (IL)-1β, IL-6, and IL-10, as well as expression of IL-6 mRNA, were attenuated, especially in L. plantarum treated rats. The increased renal expression of sodium-glucose cotransporter-2 (SGLT2), but not that of glucose transporter type-5 (GLUT5), was suppressed by the treatment with L. plantarum. Conclusion: Suppression in insulin signaling pathway together with the induction of inflammatory markers and upregulation of SGLT2 in fructose-fed rats were improved by L. plantarum supplementation. These findings may offer a new approach to the management of renal dysregulation induced by dietary high-fructose.
High dietary fructose intake causes a metabolic disorder and augments the risk of chronic kidney disease most likely due to oxidative stress. Probiotics could have antioxidant, antiinflammatory and immunoregulatory properties. The present study examined the influence of Lactobacillus helveticus and Lactobacillus plantarum supplementation on dietary fructose-induced metabolic changes and renal antioxidant/oxidant status of rats. Male Wistar rats were divided into four groups as follows: control; fructose; fructose plus L. helveticus; fructose plus L. plantarum. Fructose was given to the rats as a 20% solution in drinking water for 15 weeks. The probiotic supplementation was applied by gastric gavage once a day for six weeks. Several metabolic parameters in the plasma, gene and protein expressions of the main antioxidant enzymes in renal tissues of rats were measured. Dietary fructose-induced elevations in plasma insulin, triglyceride, VLDL, creatinine as well as renal urea levels were alleviated after treatment with L. helveticus and L. plantarum. Moreover, L. helveticus and L. plantarum supplementation recovered the changes in renal protein expression level of SOD1, SOD2 and CAT. In conclusion, supplementation with L. helveticus and L. plantarum has an improving effect on specific metabolic parameters and renal antioxidative enzymes in a fructose-induced metabolic disorder.
Background:Mushrooms have been valued for their nutritive content and as traditional medicines; several important medicinal properties of mushrooms have been recognized worldwide.Objective:The purpose of this study was to elucidate the cell growth inhibitory potential of four edible mushrooms; Coprinus comatus (O.F. Mull.) Pers. (Agaricaceae), Tricholoma fracticum (Britzelm.) Kreisel (Tricholomataceae), Rhizopogon luteolus Fr. and Nordholm (Rhizopogonaceae), Lentinus tigrinus (Bull.) Fr. (Polyporaceae) on hepatocellular carcinoma (HepG2) cells in conjunction with their antioxidant and antibacterial capacities.Materials and Methods:Five different extracts of edible mushrooms were obtained using water, methanol, acetone, n-hexane and chloroform as solvent systems for cytotoxic, antioxidant and antibacterial properties.Results:C. comatus showed substantial in vitro cytotoxic activity against HepG2 cell lines with all extracts especially with chloroform 50% inhibition (IC50 value of 0.086 mg/ml) and acetone (IC50 value of 0.420 mg/ml). Chloroform extract of C. comatus had maximum amount of β-carotene (25.94 μg/mg), total phenolic content (76.32 μg/mg) and lycopene (12.00 μg/mg), and n-hexane extract of L. tigrinus had maximum amount of flavonoid (3.67 μg/mg). While chloroform extract of C. comatus showed the highest 2, 2-diphenyl-1-picrylhydrazyl (DPPH) capturing activity (1.579 mg/ml), the best result for metal chelating activity was obtained from methanolic extract (0.842 mg/ml). Moreover, all tested mushrooms demonstrated antibacterial activity and n-hexane extract of L. tigrinus and acetone extracts of T. fracticum were the most active against tested microorganism.Conclusion:These results indicate that different extracts of investigated mushroom have considerable cytotoxic, antioxidant and antibacterial properties and may be utilized as a promising source of therapeutics.
Many plants, such as Dieffenbachia Schott, which are poisonous and can be life threatening, are present in the habitats of people. Dieffenbachia is widely used for ornamental purposes in living quarters, but it is a plant species that can harm human health as a result of contact, chewing or ingestion. The aim of this work is to attract the attention of researchers to the role of the Dieffenbachia plant, often used for ornamental purposes in homes, especially in the case of home accidents that children are exposed to and the likelihood of abuse. For this reason, Dieffenbachia poisoning cases in the literature have been discussed in the context of resources. A total of 7 cases were studied, including three cases of 1-3 years of age, 3 cases of 7-12 years and a case of adult age of 69, obtained by investigating the literature. Dieffenbachia plant can cause vital signs, such as airway obstruction and respiratory failure, as well as mild skin reactions, depending on the type of contact and amount of exposure. Care should be taken and caution should be exercised on the use of plants such as Dieffenbachia and similar plants in houses, playgrounds and other green area regulations.
This study was designed to reveal cell growth inhibitory potential of six different edible mushrooms: Ramaria flava, Agrocybe molesta, Volvopluteus gloiocephalus, Lactarius deliciosus, Bovista plumbea, and Tricholoma terreum on HepG2 cells together with their antioxidant and antibacterial power. Methanolic extracts of V gloiocephalus and aqueous extracts of R. flava had the most potential cytotoxic effects over HepG2 cells. The best results for 2,2-diphenyl-1-picrylhydrazyl radical scavenging activities were obtained from both aqueous and methanolic extracts of R. flava. Methanolic extracts of T. terreum (IC50 = 1.62 mg/mL) and aqueous extracts of B. plumbea (IC50 = 0.49 mg/mL) showed maximum metal chelating activity. The highest reducing capacities were observed among the methanolic extracts of R. flava (EC50 = 1.65 mg/mL) and aqueous extracts of B. plumbea (EC50 = 1.71 mg/ mL). High-performance liquid chromatography analysis revealed the presence of many phenolic compounds in macrofungi; gallic acid and p-coumaric acid were the two main phenolics identified in all extracts. Antibacterial studies indicated that all six tested mushrooms showed antibacterial activity on at least three microorganisms. These results indicate that different extracts of the investigated mushrooms have considerable cytotoxic, antioxidant, and antibacterial properties and may be utilized as a promising source of therapeutics.
In the present study, Veronica multifida leaf extract and zinc acetate dihydrate were utilized to synthesize zinc oxide (ZnO) nanoparticles (NPs) eco-friendly and cost-effectively under different physical conditions. Soxhlet extractor was used for the preparation of aqueous plant extract. UV-Vis (ultraviolet–visible) spectrophotometer, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and transmission electron microscope (TEM) were used to characterize the ZnO NPs. UV-Vis spectrophotometer in the range of 200–800 nm was used to get information about the formation of ZnO NPs at different pH and temperatures. FTIR spectrum revealed the presence of functional groups in ZnO NPs. XRD, scanning electron microscope, and TEM analyses confirmed the crystal structure and average size of ZnO NPs. The antimicrobial activities of ZnO NPs were tested on microorganisms, that is, Escherichia coli ATCC 43895 , Staphylococcus aureus ATCC 29213 , Bacillus subtilis, Bacillus licheniformis, Pseudomonas aeruginosa, and Salmonella typhimurium. Moreover, antibiofilm activity of ZnO NPs was performed against P. aeruginosa and S. aureus ATCC 29213. ZnO NPs have shown effective antimicrobial and antibiofilm activities against tested microorganisms. The results elucidated that eco-friendly and cost-effectively produced ZnO NPs could be used as coating materials and in a wide range of industrial applications, such as pharmaceutical industries and cosmetics.
