Effects of Stingless Bee Propolis on Experimental Asthma
Bee products have been used empirically for centuries, especially for the treatment of respiratory diseases. The present study evaluated the effect of treatment with a propolis hydroalcoholic extract (PHE) produced by Scaptotrigona aff. postica stingless bee in a murine asthma model. BALB/c mice were immunized twice with ovalbumin (OVA) subcutaneously. After 14 days, they were intranasally chal...
متن کاملEffects of stingless bee and honey bee propolis on four species of bacteria.
We examined the antibacterial activities of several types of propolis, including Africanized honey bee green propolis and propolis produced by meliponini bees. The antibacterial activity of green propolis against Micrococcus luteus and Staphylococcus aureus was superior to that of Melipona quadrifasciata and Scaptotrigona sp propolis. Only two samples of propolis (green propolis and Scaptotrigo...

15 صفحه اولStingless Bee Propolis from Indonesia Induces In Vitro Cytotoxicity and Apoptosis in Cancer Cell Lines
Both genetic and environmental factors are known to play a role in causing cancer (Iwasaki and Tsugane, 2011). For the last few decades the standard cancer treatments have involved surgery, radiation and chemotherapy. However, metastatic disease frequently redevelops even after surgery. In addition, the typical systemic treatment regime has often led to intolerable side-effects. Chemotherapeuti...
