background and aims. since intracanal medicaments can affect the cell viability in periapical tissues, the aim of this study was to evaluate the effect of calcium hydroxide and propolis on pulp fibroblasts. materials and methods. two healthy third molars were used as a source to obtain fibroblasts. the fibroblasts were cultured and subjected to 1 mg/ml of propolis and calcium hydroxide. this ex...

Article history: Received on: 05/05/2016 Revised on: 17/07/2016 Accepted on: 19/10/2016 Available online: 31/01/2017 Antimicrobial resistance (AMR) is among the threats to global public health, with developing countries being mostly affected. The AMR has undermined development of new antimicrobial agents by pharmaceutical industries despite new emerging infections. This necessitates a search fo...

High temperature high resolution gas chromatography coupled to mass spectrometry (HT-HRGC-MS) isa powerful analytical tool. In this work we applied this technique to the study of crude extracts of propolis collected near the city of Uberlândia-Minas Gerais State. Eucalyptus trees and native plants from "cerrado" (savannah) were the material sources disposable for the Apis mellifera bees. A lot ...

The goal of this work was to investigate a possible synergistic effect between ethanolic extracts of propolis from Brazil and Bulgaria and some antibiotics (Amoxicillin, Ampicillin and Cefalexin) against Salmonella Typhi. Brazilian and Bulgarian propolis showed an antibacterial action, but the sample from Bulgaria was shown to be more efficient. Both samples showed a similar synergistic effect ...

Propolis is a honeybee product known for its biological and pharmacological properties for centuries. It has been extensively used in traditional medicine and also, because of its antibacterial, antiseptic, anti-inflammatory, and anesthetic activities, in complementary medicine. Propolis became subject of numerous studies developed and carried out all over the world in order to analyze its chem...

Propolis is a bee product that has been extensively used in alternative medicine and recently has gained interest on a global scale as an essential ingredient of healthy foods and cosmetics. Propolis is also considered to improve human health and to prevent diseases such as inflammation, heart disease, diabetes and even cancer. However, the claimed effects are anticipated to be correlated to it...

Flavonoids have been considered the main biologically active components in propolis. However, a new variety of flavonoid-free propolis was recently found and chemically classified as type 6. Because it showed activity against oral microorganisms, this study evaluated the effects of the crude ethanolic extract of this propolis and its chemical fractions on the activity of purified glucosyltransf...

Propolis and geopropolis are resinous products of bees showing antimicrobial effects. There is no data concerning their action against Pythium insidiosum - the causative agent of pythiosis, a pyogranulomatous disease of the subcutaneous tissue that affects mostly horses, dogs and humans. Fragments of 15 isolates of P. insidiodum were incubated with propolis and geopropolis extracts and evaluate...

Propolis, a honeybee product, has gained popularity as a food and alternative medicine. Its constituents have been shown to exert pharmacological effects, such as anti-microbial, anti-inflammatory and anticancer. Shoot apices of Baccharis dracunculifolia (alecrim plant, Asteraceae) have been pointed out as sources of resin for green propolis. The present work aimed (i) to observe the collecting...

Extracts of propolis samples collected in Brazil and Bulgaria were assayed against four Leishmania species--Leishmania amazonensis, L. braziliensis, L. chagasi from the New World, and L. major from the Old World--associated to different clinical forms of leishmaniasis. The composition of the extracts has been previously characterized by high temperature high resolution gas chromatography couple...
