AIM An in vivo experiment was conducted to investigate the effect of different levels of ethanolic extract of propolis, on growth performance, carcass traits, serum biochemistry, and humoral immune responses of chickens, as compared with the antibiotic flavophospholipol. MATERIALS AND METHODS 312 1-day-old as-hatched broiler chicks (Ross 308) were randomly allotted to 6 treatments with 4 repl...

The pathogenic role of inflammation and oxidative stress in chronic kidney disease (CKD) is well known. Anti-inflammatories and antioxidant drugs has demonstrated significant renoprotection in experimental nephropathies. Moreover, the inclusion of natural antioxidants derived from food and herbal extracts (such as polyphenols, curcumin and lycopene) as an adjuvant therapy for slowing CKD progre...

AIM This study evaluates the disinfection of dentinal tubules using Propolis, Azadirachta indica (alcoholic and aqueous extracts), 2% chlorhexidine gel and calcium hydroxide against Candida albicans biofilm formed on tooth substrate. MATERIALS & METHOD One hundred and five human teeth were infected with Candida albicans for 2 days. Samples were divided into 7 groups. Group I- Propolis, Group ...

Total phenolic contents, antioxidant activity and chemical composition of propolis samples from three localities of Minas Gerais state (southeast Brazil) were determined. Total phenolic contents were determined by the Folin-Ciocalteau method, antioxidant activity was evaluated by DPPH, using BHT as reference, and chemical composition was analyzed by GC/MS. Propolis from Itapecerica and Paula Câ...

We investigated the effects of the two fractions, aqueous (AEP) and ethanolic extracts of propolis (EEP) of the Brazilian propolis on azoxymethane (AOM)-induced aberrant crypt foci (ACF). Male Wistar Hannover (GALAS) rats were administered two weekly subcutaneous injections of AOM (20 mg/kg bw) and fed with diets mixed with AEP (100, 500 and 1,000 ppm) or EEP (500 and 1,000 ppm) for 4 weeks, st...

Propolis is an apiculture product containing beeswax, bee saliva and resins that bees collect from selected plants. Among the various uses of propolis by hive, protection against natural enemies, chiefly microbial origin, stands out, contributing to enhance hive immunity resistance infection. Most known types have phenolic substances as main resin constituents. Several compounds including flavo...

Propolis has been used since ancient times in folk medicine. It is a popular medicine possessing a broad spectrum of biological activities. This material is one of the richest sources of polyphenolic compounds such as flavonoids and phenolic acids. The ethanolic extract of propolis (EEP) evokes antibacterial, antiviral, antifungal and anticancer properties. Due to pharmacological properties it ...

Propolis, a resinous substance that honeybees collect to protect their beehive from enemies, is reported to have various biological activities. In our screening program to search for antiangiogenic compounds from propolis, the ethanol extracts of Okinawan propolis (EEOP) showed significant antiangiogenic activities in a tube formation assay with human umbilical vein endothelial cells (HUVECs) i...

Recently, two chemically different types of Brazilian propolis (type-3 and -12) were shown to have cariostatic properties. This study aimed to evaluate the influence of their isolated fractions on mutans streptococci viability, glucosyltransferases (GTFs) activity and caries development in rats. The ethanolic extracts of propolis (EEPs) were serially fractionated into hexane (H-fr), chloroform,...
