ABSTRACT
Due to emerging drug resistance in pathogenic organisms, most of the second generation antibiotics are not effective in controlling the disease. As a consequence, the dosage and duration of drug intake has increased leading to drug induced toxicity and various side effects. A large number of natural products are being reported to ameliorate the toxicity and oxidative stress caused by antibiotics. Here, we explored the antioxidative potential of honey bee product propolis alone as well as in combination with antibiotics in Staphylococcus aureus infected BALB/c mice. For experimental design, mice were divided in to seven groups and decapitated after experimental period. Kidney was excised, homogenized and then used for different biochemical and histopathological estimations. Results observed after treatment with propolis and antibiotics were compared with those of S. aureus infected group. Results showed increase in lipid peroxidation, decrease in reduced glutathione levels and antioxidant enzymes such as; catalase, superoxide dismutase, glutathione-S-transferase, glutathione peroxidase and glutathione reductase. On the contrary, treatment with propolis, led to reduction in levels of LPO and increase in activities of antioxidant enzymes. Also, histopathology of kidney and all kidney function enzymes were restored to near normal.
ABSTRACT
El objetivo de la investigación fue determinar el nivel de efectividad antimicrobiana in vitro de propóleos altos en compuestos fenólicos de origen costarricense sobre las especies streptococcus sanguinis y streptococcus mutans. Se midió la acción bacteriostática o bactericida del propóleo en una concentración al 50%, 70% y 80%, comparando su efecto contra el digluconato de clorhexidina al 0,12%. El análisis evidenció que el propóleo ejerce una acción bactericida sobre la especie streptococcus sanguinis independientemente de su concentración, y por otra parte sobre la bacteria streptococcus mutans las concentraciones del propóleo al 50% y 70% resultaron en acción bacteriostática. De forma tal se concluye que los tres extractos del propóleo generaron un efecto antimicrobiano sobre las especies S. mutans y S. sanguinis. Se obtuvieron efectos bactericidas de los extractos del propóleo similares al gluconato de clorhexidina al 0,12%, y esto justifica que puede ser empleado como herramienta para la prevención o coadyuvante del tratamiento de la enfermedad periodontal y reducción del riesgo de caries.
The aim of the research was to determine the In Vitro level of antimicrobial effectiveness of Costa Rican propolis high in phenolic compounds on the species Streptococcus Mutans and Streptococcus Sanguinis. It was measured the bacteriostatic and / or bactericidal action of propolis in 50%, 70% and 80% concentration, comparing their effect against chlorhexidine 0.12%. The analysis showed that propolis proved a bactericidal effect on the species Streptococcus Sanguinis regardless of their concentration; on the other hand on the propolis concentrations of 50% and 70% on the bacterium Streptococcus mutans resulted in bacteriostatic action. It is concluded that the three extracts of propolis generated an antimicrobial effect on the species S. mutans and S. Sanguinis. Antibacterial effects from extracts of propolis were similar to chlorhexidine 0.12%, this justifies that can be used as a tool for prevention and / or adjunctive treatment of periodontal disease and reduction of tooth decay risk.
ABSTRACT
Propolis, also known as bee glue, is a substance collected by worker bees and it is used as a material for constructing and maintaining their beehives. It has been used topically and orally by humans for its anti-inflammatory properties. However, the growing use of propolis has been paralleled by reports of allergic contact dermatitis as a reaction to the substance. Contact dermatitis with generalized cutaneous manifestations elicited by propolis ingestion has not been previously reported. Here we report on the first case of systemic contact dermatitis from propolis ingestion in a 36-year-old woman.

The ''in vitro'' antibacterial activity of ethanol extract of propolis (EEIP) from Urmia, Iran was investigated against three prevalent species of fish bacterial pathogens including: Aeromonas hydrophila LMG 3770, Yersinia ruckeri LMG 3279 and Streptococcus iniae LMG 14520. In this study two standard susceptibility testing techniques (Micro-broth dilution method and Agar-well diffusion method) were used to evaluation of the antibacterial activity of EEIP against the mentioned micro-organisms. Also the chemical composition of propolis was determined by the method of Gas chromatography-mass spectrometry (GC-MS). Twenty-six compounds were identified by gas chromatography-mass spectrometry analysis. Results showed Chemical composition of EEIP contained significant amounts of flavonoids, Sesquiterpenes - mainly Eudesmol and Caryophyllene oxide - aromatic acid, and low amounts of aldehydes and triterpens. Furthermore the ethanol extract of propolis inhibited the growth of all examined micro-organisms with the highest antimicrobial activity against Gram-positive bacteria Streptococcus iniae. Ethanol did not influence the antimicrobial effect of EEIP. These antibacterial properties would warrant further studies on the clinical applications of propolis in aquaculture field.
