Medicinal plants from the Caatinga, a Brazilian xeric shrubland, are used in folk medicine to treat infections. These ethnopharmacological data can contribute obtaining new antimicrobial/antibiofilm extracts and natural product prototypes for development of drugs. The aim this study was investigate antibiofilm antibacterial activities 45 aqueous 24 Caatinga plant species.The effect on planktonic cells biofilm formation by Staphylococcus epidermidis studied OD(600) absorbance crystal violet...
Thermal lesions were produced in 12 male Wistar rats, positioning a massive aluminum bar 10 mm diameter (51 g), preheated to 99°C ± 2°C/10 min. on the back of each animal for 15 sec. After 7, 14, 21, and 28 days, animals euthanized. The edema intensity was mild, with no bubble formation thick dry crust from 3rd day. percentage tissue shrinkage at days 66.67 1.66%. There sign infection, bleeding, or secretion. Within reepithelialization incomplete, fibroblastic proliferation moderate fibrosis...
A new hydrogel based on two natural polysaccharides was prepared in aqueous medium with 1.7% (w/v) galactomannan (from Cassia grandis seeds) and different concentrations of κ-carrageenan (0.3, 0.4 0.5%w/v), CaCl2 (0.0, 0.1 0.2M) pH (5.0, 5.5 6.0), using a full factorial design rheological parameters. The best formulation obtained 0.5% κ-carrageenan, containing 0.2M at 5.0. Nuclear magnetic resonance scanning electron microscopy where used order to characterize the formulation. shelf life...
Due to the use of Cleome spinosa Jacq. (Cleomaceae) in traditional medicine against inflammatory and infectious processes, this study evaluated vitro antimicrobial potential phytochemical composition extracts from its roots leaves. From leaves (L) (R) C. different were obtained (cyclohexane: ChL ChR; chloroform: CL CR; ethyl acetate: EAL EAR, methanol: ML MR). The activity was by broth microdilution method obtain minimum inhibitory (MIC) microbicidal (MMC) concentrations 17 species,...
The aim of this work was to analyse the antimicrobial properties a purified lectin from Eugenia uniflora L. seeds.The E. (EuniSL) isolated seed extract and by ion-exchange chromatography in DEAE-Sephadex with purification factor 11.68. showed single band on denaturing electrophoresis, molecular mass 67 kDa. EuniSL agglutinated rabbit human erythrocytes higher specificity for erythrocytes. haemagglutination not inhibited tested carbohydrates but glycoproteins exerted strong inhibitory action....
A novel lectin was isolated from Bothrops leucurus snake venom using a combination of affinity and gel filtration chromatographies. The (BlL) agglutinated glutaraldehyde-treated rabbit human erythrocytes with preference for erythrocytes. Galactose, raffinose, lactose, fetal bovine serum casein inhibited lectin-induced erythrocyte agglutination. BlL, molecular mass 30 kDa composed two subunits 15 kDa, showed dependence on calcium. BlL is an acidic protein highest activity over the pH range...
A new lectin, BfL, was purified from Bauhinia forficata seeds by ammonium sulfate fractionation, DEAE-Sephadex ion exchange chromatography, Sepharose-4B and chitin affinity chromatographies Superdex 75 size exclusion chromatography. The molecular homogeneity purity of BfL were assessed reversed-phase HPLC. appeared as a single band approximately 27.0 kDa on SDS-PAGE under non-reducing reducing conditions, its weight determined to be 27,850 Da LC/ESI-MS. is glycoprotein with carbohydrate...
