Propolis is produced by honeybees and has many biological properties, including immunomodulatory, antiinflammatory, anti-oxidant, anti-bacterial, anti-viral and anti-cancer actions. Five ethanol extracts of Brazilian propolis were tested for inhibition of 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced inflammation in mice. The ethanol extract of Brazilian propolis AF-08 markedly inhibited T...

Platelet hyperactivity plays an important role in arterial thrombosis and atherosclerosis. The present study was aimed to investigate the effects of different extracts of propolis and components of flavonoids on platelet aggregation. Platelet-rich plasma was prepared and incubated in vitro with different concentrations of the tested extracts and components of flavonoids. Platelets aggregation w...

Propolis has been used as a medicinal agent to treat infections and promote wound healing for centuries. The aim of the present study was to test the antimicrobial, antioxidant, and cytotoxic activities of a new type of Brazilian propolis, popularly called red propolis, as well as to analyze its chemical composition. The antimicrobial activity against Staphylococcus aureus ATCC 25923 and Staphy...

OBJECTIVE The aim of this study was to evaluate the antibacterial property of glass-ionomer cement (GIC) containing propolis against Streptococcus mutans and its effect on the in vitro S. mutans biofilm formation. METHODS Ethanolic extract of propolis (EEP) was prepared at two concentrations as 25 and 50%. Three different experimental GIC disks were prepared using pure liquid and liquid solut...

Background: Pasteurella multocida continues to pose a danger to prone farm and wild animals all over the world. Chemotherapeutic treatments are progressively losing their effectiveness, last for long time, and cost a lot of money, as well as being toxic to human consumers. Therefore, clearing the way for immunization as a big-wheel alternative against the economic grain. Yet, the vaccines avail...

background and objectives:increased antibiotic resistance as a result of using antimicrobial drugs and also their various adverse effects has caused that in recent years, investigation of medicinal plants beconsidered for discovering new medicinal resources against bacterial infections. this study was performed with the objective of determining the antimicrobial activity of aqueous and ethanoli...

The effects of aqueous and ethanolic leaf extracts of Mentha Longifolia on morphine dependence were examined in mice. Dependence was induced using subcutaneous injections of morphine daily for 3 days. On day 4, the last dose of morphine was injected 2 h perior the intraperitoneal injection of naloxone. The number of episods of jumping during 30 minutes after injection of naloxane was considered...

Pistacia vera L., a member of Anacardiaceae family, has been used for sedation and analgesia in traditional medicine. In this study, the antinociceptive and anti-inflammatory effects as well as acute toxicity of the aqueous and ethanolic extracts of P. vera leaves were investigated in mice. The antinociceptive activity was studied using hot plate and writhing tests. The effect of the extracts a...

the anti-ischemic effect of aqueous and ethanolic extracts of nigella sativa l. seed was studied using a four-vessel occlusion model in rats. the ischemia was evaluated by optical and transmission electron microscopy. after 20 min of forebrain ischemia, agents were administered intraperitoneally after reperfusion. both extracts comprised an alkaloid. in ischemic rats, the aqueous (1 g/kg) and e...

Purpose: Cholinesterase inhibitors are the class of compounds which inhibit cholinesterase enzyme. These are used as drugs for symptomatic treatment of Alzheimer’s disease (AD). The present study, evaluate antibutyrylcholinestease property of ethanolic extract of Shorea robusta de oil cake (DOC). Method: Ellman’s method was used to determine the butyrylcholinesterase (BuChE) enzyme inhibitory a...
