Propolis suppresses tumor angiogenesis by inducing apoptosis in tube-forming endothelial cells.
(49/151)
We have reported that propolis suppresses tumor-induced angiogenesis in vivo and in vitro, but antiangiogenic mechanism of propolis at cellular level remains unclear. In this study, we observed that propolis not only inhibited tube formation but also induced apoptosis of endothelial cells. These results suggest that propolis exerts its antiangiogenic effects at least in part through induction of apoptosis. (+info)

Twenty eight female Wistar rats weighing 150-200 g were used in this study and these animals were divided into 4 groups, each comprising 7 rats. The first group served as the control group, and groups 2, 3, and 4 were administered a single dose of 250 mg/kg.bw propolis, a single dose of 125 mg/kg.bw (1/2LD(50)) cypermethrin, and a single dose of 125 mg/kg.bw cypermethrin followed by a single dose of 250 mg/kg.bw propolis 30 min later, per os using a catheter, respectively. Twenty-four hours after propolis administration, blood and tissue (liver, kidney, and brain) samples were collected. Serum glucose, triglyceride, uric acid, cholesterol, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) activities/levels, plasma and tissue malondialdehyde (MDA) levels, and erythrocyte and tissue superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) activities were determined. Compared to group 1, significant increases in plasma and tissue MDA levels and kidney GSH-Px activity, and significant decreases in erythrocyte SOD and CAT, liver SOD and GSH-Px, kidney SOD and brain SOD, CAT and GSH-Px activities were determined in group 3. Compared to group 1, a significant increase in glucose and a significant decrease in triglyceride levels were determined in group 3. Values pertaining to group 4 were demonstrated to be closer to those of group 1. (+info)

Comparison of Thymus vulgaris (Thyme), Achillea millefolium (Yarrow) and propolis hydroalcoholic extracts versus systemic glucantime in the treatment of cutaneous leishmaniasis in balb/c mice.
(56/151)
BACKGROUND & OBJECTIVES: Leishmaniasis is a parasitic disease transmitted by sand flies. Many investigations are performed to find an effective and safe treatment for leishmaniasis. In this study, we evaluated the efficacy of herbal extracts of Thymus vulgaris (Thyme) and Achillea millefolium (Yarrow), propolis hydroalcoholic extract and systemic glucantime against cutaneous leishmaniasis in Balb/c mice. METHODS: A total of 45 mice were randomised into five groups each including nine mice. They were treated with pure ethanol 70 degrees, systemic glucantime, Achillea millefolium hydroalcoholic extract, Thymus vulgaris hydroalcoholic extract and propolis hydroalcoholic extract for six weeks. The statistical tests including student t-test were used for analysis. Data were analyzed by SPSS software, ver 13.00. RESULTS: Mean of ulcer size reduction were -17.66, -22.57, 43.29, 36.09 and 43.77% for the alcohol, glucantime, yarrow, thyme and propolis groups, respectively. The results were suggestive that Thymus vulgaris, Achillea millefolium and propolis hydroalcoholic extracts were significantly more effective in reduction of ulcer size as compared with glucantime (p = 0.006, 0.002 and 0.008, respectively). INTERPRETATION & CONCLUSION: Our results are suggestive that Thymus vulgaris, Achillea millefolium and propolis extracts are effective for treatment of cutaneous leishmaniasis in mice. Regarding these results, we suggest that efficacy of these extracts alone or in combination are evaluated against human cutaneous leishmaniasis as a randomized clinical trial. (+info)
