Biofilms are complex communities of microorganisms attached to surfaces or associated with interfaces. Since biofilm formation is influenced by the type of surface materials, in the current study it was aimed to compare copper, stainless steel, galvanized stainless steel, polyvinyl chloride, polyethylene, polypropylene, ceramic and glass surfaces for biofilm formation rate. In this study, both monthly collected water and biofilm samples were analyzed in terms of total coliforms, faecal coliforms, Pseudomonas , aerobic mesophilic heterotrophic bacteria (at 22 and 37°C) and amoebas. We found that plastic polymers, especially polyethylene and polypropylene, supported the lowest total aerobic mesophilic heterotrophic bacterial numbers. Although the protozoa (amoeba) could found on to all of the surfaces, Pseudomonas species could harbour none of them. It can be concluded that selection of the suitable pipe material could reduce waterborne disease and minimize the possibility of biofilm development associated with the operation of cooling tower systems.

Ten aqueous and one ethanolic extracts from medicinal plants used in Turkey were evaluated for antimicrobial activity. Plant extracts were prepared using distilled water and 50 % ethanol. It was found that three plant extracts from the 9 plants studied had antibacterial activity. These activities were produced by the aqueous extracts of Pistacia, Tilia argentea and Anthemis pungens. All of these plant extracts had antibacterial activity against E.coli. Also, Tilia argentea and Pistacia spp inhibited the growth of Bacillus subtilis. In addition to these bacteria, Klebsiella pneumoniae, Staphylococcus aureus and environmental Aeromonas spp. strains were inhibited by Tilia argentea.

The distribution and functional morphology of neuroendocrine cells (PNECs) were studied in the lung of tadpole and adult Rana ridibunda. The responses of PNECs to different experimental conditions were investigated in adult frog lungs. In tadpole lungs, bombesin- and somatostatin immunoreactive (IR) PNECs were found in the inner-lining epithelium. In adult frogs kept in cold water (+ 4 oC), mostly serotonin- and bombesin-IR cells had stored secretory material as well as serotonin-IR cells with released secretion, while somatostatin-IR cells with limited secretory material were scarce. In the dry aquarium, somatostatin-IR cells of adult frogs were at various secretory stages. In conclusion, the activities of PNECs varied by depending on the amount of pulmonary contribution of lungs into respiration.

The Rezve stream originates from the Istranca Mountains and flows into the Black Sea. The stream borders Turkey and Bulgaria and is under military defense. Beyond that very little is actually known about this stream. It is very hard to study in this area because the region is fraught with geographic irregularities and covered with dense forests. Also there isn't any study about Ostracoda fauna in the Rezve stream. The present paper reports the Ostracoda assemblages of Rezve stream for the first time from Turkey.

Concentrations of Cd, Cu, Co, Cr, Fe, Ni and Zn in the moss ( Hypnum cupressiforme and Scleropodium purum) and topsoil (0-5 cm) samples collected from Istanbul were analysed to estimate heavy metal deposition. The activity concentrations of gamma emitting radionuclides ( 137 Cs, 40 K, 238 U, 232 Th), organic matter contents and pH values of the topsoil samples were also measured. The trace element and radionuclide levels were compared with those found in the samples from other locations of Turkey and different countries.

The valuable contents of the vitamins based on % daily value were obtained with comparison of the recommended intakes for indivuduals in life stage groups according to dietary reference intakes (FAO/DRIs). Concentration profile of the vitamins compared to the values of the life stage groups were also significantly correlated in general. Investigated traits in the fruits of Prunus spinosa subsp. dasyphllum may be significant to explain the chemotaxonomic and evolutional characteristics as additional parameters and its alternative natural product potential as vegetable genetic resources in the genepool of Anatolia.

Total seed oil and fatty acid compositions of two informal groups of Anchusa officinalis L. were studied in order to provide additional information for the delineation of the groups. Major fatty acids were linoleic (C18:2n6), oleic (C18:1n9), α-linolenic (C18:3n3), γ-linolenic (C18:3n6), palmitic (C16:0) and stearidonic acid (C18:4n3) respectively. The lower levels were observed in stearic (C18:0), eicosenoic (C20:1n9) and erucic acids (C22:1n9). Linoleic (24,4 to 25,8%) and oleic acids (23,2 to 25,5%) were detected in the highest levels. α-linolenic (14,5 to 15,1%) and γ-linolenic acid (12,5 to 12,6%) as an unusual fatty acid in plants were also at the high concentrations in both groups. Saturated fatty acids in total were observed at the lower levels generally (1,9-8,9%). Significantly difference for the fatty acid profiles between the groups were found (p<0,05). Differences were also significant for saturated (palmitic and stearic) and unsaturated fatty acids, and for their some ratios (p<0,05). Total percentages of poly-unsaturated (56,27 to 56,41%), mono-unsaturated (26,47 to 31,38%) and saturated fatty acids (10,12 to 11,95%) were quantified closely in both groups. The parameters examined here may be useful as additional biochemical marker set for the discrimination of Anchusa at infraspesific levels. Valuable concentrations for essential poly-unsaturated fatty acids (PUFAs) including linoleic, α-linolenic and γ-linolenic acid as special dietetics and nutraceuticals suggest the alternative source potential of A. officinalis .

Adriamycin (ADR) is an antineoplastic drug, isolated from Streptomyces peucetius var. caesius , and has cytotoxic features. It binds DNA by intercalation and inhibits replication and transcription. Clinically, ADR is used intravenously and intravesically. Ehrlich ascites tumor (EAT) was originated from breast carcinoma in a mouse. It grows in solid and ascitic forms. The aim of our study is to investigate the effectiveness of ADR on mice bearing EAT by comparing its administration routes. 0.01 mg.g -1 ADR was administered mice bearing EAT via intraperitoneal, intravenous and subcutaneous. On day 0 each mouse in the experiment was inoculated with 3x10 5 EAT cells. On the 2 nd , 4 th , 6 th , 8 th days after administration, number of viable cells and mitosis number were counted from each animal by drainage the ascites fluid from the peritoneal cavity of each mouse. Data were evaluated statistically. The most efficient in respect of curing properties was observed in group I in which ADR administered via intraperitoneal.
