Effects of propolis and pollen supplementations on growth performance and body components of Japanese quails (Coturnix coturnix japonica).

Abstract The present study was carried out to investigate the effects of honey bee propolis and pollen supplementation on growth performance and body components in quail (Coturnix coturnix japonica). Two experiments were conducted. In the first experiment, propolis ethanolic extract (30%, PEE) was supplemented in diets at levels of 0, 5 and 10 ml PEE kg-1 while in the second experiment, pollen was supplemented in diets at four levels (0, 5, 10 and 20 g pollen kg-1). In both experiments, chicks were fed with diet containing 240 g crude protein and 3100 kcal ME per kg diet. During the experimental period, body weight, feed consumption and feed efficiency were determined weekly. At the end of the experiments, 3 female and 3 male quail from each subgroup were killed humanely to determine body components. Experimental results showed that supplementation of PEE and pollen did not significantly affect body weight gain, feed efficiency or body components (P > 0.05). It was concluded that propolis and pollen had no effect at the levels investigated on performance and body components of quail

Natural product propolis: Chemical composition

PubMedID: 15715264The chemical composition of propolis from East Mediterranean (Hatay, Adana and Mersin) was studied in order to determine the major compounds by using GC-MS. In this study, the ethanolic extract of propolis prepared by mixing 1900 mL 70% ethanol and 100 g propolis was used. Chemical analysis of propolis extracts indicated that the propolis samples had high concentrations of the aromatic acids, esters and other derivatives which are responsible for the anti-bacterial, anti-fungal, anti-viral, anti-inflammatory and anti-cancer properties of propolis such as benzyl cinnamate, methyl cinnamate, caffeic acid, cinnamyl cinnamate and cinnamoylglcine besides the most common compounds as fatty acid, terpenoids, esters, alcohols hydrocarbons and aromatic acids. © 2005 Taylor & Francis Ltd

Heavy metals, trace elements and biochemical composition of different honey produce in Turkey

In this work, the biochemical composition, trace elements and heavy metal contents of honey samples, which were collected from different regions and different botanical origin in Turkey were evaluated. The average content of minerals, moisture, acidity, hydroxymethylfurfural, diastase, invert sugar, pH, sucrose, electrical conductivity and heavy metal contents were determined. The biochemical composition of different botanical originated honeys were determined within the limits of Turkish Standard Institution (TSE), CODEX and EU standards. Level of invert sugar in cotton honey and sucrose level in sunflower honey weren't found agree with TSE and EU standards. In addition to bio- chemical compositions, the presence of Al, Ba, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb and Zn were determined agree with ICP AES. The highest value of Cr, Cu, K, Mn, Na and Al, contents were found in pine honeydew honey with a levels of 0.50,2.14,1931,1.46,285,7.49 mg kg"1, respectively. The highest level of Cd, Co, Mg, Ni and Pb (0.32, 0.22,103,0.64,1.29 mg kg -1) were found in cotton honey. The highest level of Ba and Zn were determined in multifloral honey with a level of 1.47 ppm and 3.29 ppm, respectively. K, Na and Mg were the major macro elements in all honey samples. This study showed that the source of nectar and ecological regions have an important effect on the bio- chemical compositions, trace elements and heavy metals contents of honey

The effects of additive feeding and feed additives before wintering on honey bee colony performances, wintering abilities and survival rates at the East Mediterranean region

In this study; the effects of additive feeding with vitamin, fumagillin and pollen supplement on survival rates, wintering abilities, amount of adult bees and brood production were examined at subtropical temperate region before wintering. The wintering ability, survival rates, adult bees and brood areas were positively affected by feeding and feed additives. The lowest values of research components were observed on unfed control groups colonies. © 2006 Asian Network for Scientific Information

Effectiveness of mesalamine and propolis in experimental colitis

PubMedID: 18029336This study was conducted to investigate the effects of propolis and mesalamine on experimental colitis in rats. Distal colitis was induced in rats by intracolonic instillation of 2 mL of 4% acetic acid. The animals were randomly assigned to 5 groups: group 1, control, (n=8); group 2, colitis, received no treatment (n=8); group 3, colitis+mesalamine, 2 mL once a day via an enema (n=8); group 4, colitis+propolis, 600 mg/kg once a day via intragastric lavage (n=8); and group 5, colitis+mesalamine+propolis for 1 wk (n=8). Levels of nitric oxide were statistically significantly different in comparisons between groups 1 and 2, groups 2 and 3, and groups 4 and 5. Malondialdehyde levels were significantly different when group 2 was compared with groups 3, 4, and 5. A significant difference was observed when group 3 was compared with group 4 for myeloperoxidase. Most propolis-treated rats had normal histology; mesalamine-treated and propolis+mesalamine-treated rats had inflammatory cell infiltration at rates of 50% and 33%, respectively. The investigators concluded that propolis and mesalamine are efficient independently and in combination, but that their combined effect was not observed to be additive in experimental colitis. ©2007 Health Communications Inc

Determining predominating histologic component in malignant mixed mullerian tumors: is it worth it?

Malignant mixed mullerian tumors (MMMT) are highly aggressive tumors, usually diagnosed in advanced stage. Cases of MMMT derive from either ovary or uterus. In our study, we investigated the role of carcinomatous and sarcomatous component on response to chemotherapy and disease outcome. We retrospectively analyzed 25 patients with MMMT who were treated in our outpatient clinic from 1998 to 2003. All the paraffin specimens were reevaluated according to the histopathologic features (primary site and percentages of carcinomatous and sarcomatous component) and the effect of predominant histologic type on response to treatment. Primary tumor sites were ovary and endometrium in 36% and 64% of patients, respectively. Ten of 25 patients (40%) were treated with a combination chemotherapy regimen of cisplatin-ifosfamide (PI) and 7 patients (28%) were treated with paclitaxel-carboplatin (PC) protocol. Despite chemotherapy, 17.6% of patients had progressive disease. The remaining 13 patients (54.2%) responded to chemotherapy. Response rates of patients treated with PC (100%) were remarkably higher than the response rates of patients treated with PI (66.6%). Moreover, patients with predominating carcinomatous component had a higher response rate (87.5%) than patients with predominating sarcomatous component (66.6%). MMMT are highly chemoresponsive tumors, irrespective of primary site. One of the best predictors to response is the histologic pattern. Predominating histopathologic feature (carcinoma or sarcoma) should be taken into consideration in predicting the response and planning the chemotherapy regimen

T-cell-rich B-cell lymphoma: a clinicopathologic study of 21 cases and comparison with 43 cases of diffuse large B-cell lymphoma

Clinicopathologic features of 21 patients with T-cell-rich B-cell lymphoma (TCRBCL) were reviewed and compared to 43 patients with diffuse large B-cell lymphoma (DLBCL) to determine if there were distinguishing clinical characteristics and differences in response or survival to CHOP therapy. For the diagnosis of: TCRBCL, the current WHO criteria was used. In all of our cases, the majority of cells are non-neoplastic T cells and 0.05). The frequency of patients with TCRBCL achieving CR was 52.6% whereas that of patients with DLBCL was 79% (P < 0.003). The TCRBCL 3 years event-free survival 48% and overall survival 64% were 63 and 72% for DLBCL, respectively. (C) 2003 Elsevier Ltd. All rights reserved
