Altinterim, Basar; Gulec, Azime Kucukgul; Aksu, Onder
In this study, the safety dose of Eucalyptus camaldulensis hydrosol on carp (Cyprinus carpio) was investigated. Powdered eucalyptus leaves were mixed with deionized water and then distilled. The hydrosol was added into aquariums at doses of 0.05, 0.10 and 0.15 ml L-1 Temperature, pH, hardness and dissolved oxygen level of the water were recorded before and after hydrosol adding. The control and test experiments were repeated three times. Data obtained from the safety dose tests of E. camaldulensis hydrosol were evaluated using the Probit Analysis Statistical Method. The 5-h LC50 value (95 % confidence limit) of the safe dose of E. camaldulensis hydrosol was estimated to be 0.93 ml L-1(0.03-0.11). It can be seen that 0.05 ml L-1 doses of eucalyptus hydrosol do not create any kind of mental disorder. In the fish exposed to 0.10 and 0.15 ml L-1 doses, some mental disorders (rolling, numbness) and, at the end of 5 h, mortality in all the trial fish have been determined. The number of dead fish was significantly exposed to E. camaldulensis hydrosol (P<0.05).

Harlioglu, Muzaffer Mustafa; Kutluyer, Fitiz; Gür, Seyfettin
In the present study, the sperm number of wild caught Astacus leptodactylus was counted in the beginning of reproduction season. In addition, the reproductive system, testes, and vasa deferentia were weighed, and gonado-somatic index and testicular index were calculated. Twenty-five adult males of A. leptodactylus were used for the study. Significant linear regressions were found between body length (and weight) and sperm count, reproductive system weight, testes weight and vasa deferentia weight (P < 0.05). The mean sperm number of vas deferens for the size range of 41-56 mm carapace length crayfish was 5.72 +/- 4.54 x 10(9) sperm/distal vas deferens (DVD) section. Sperm number ranged from 4 x 10(8) to 8.5 x 10(9) sperm/DVD section. The results revealed that an increase in body weight causes an increase in sperm number. For example, mean sperm number was 3.87 +/- 2.87 x 10(9) for the weight range of 15-24 g crayfish, 5.01 +/- 2.62 x 10(9) for the weight range of 25-35 g crayfish and 7.37 +/- 2.87 x 10(9) for the weight range of 36-42 g crayfish. In conclusion, this study provides some data on the male reproduction characters and needs to be improved with details about the reproductive performance of males (i.e., sperm number and quality) in order to reach a maximum reproductive efficiency in captivity.

Güleç, Azime Kucukgul; Cengizler, Ibrahim
Tilapia (Oreochromis niloticus Linnaeus, 1758) were infected with Streptococcus iniae (Cat No: ATCC 29178) and the plasma changes in the acute phase protein (APP) members were examined at different time periods. A total of 72 fish with average body weights of 60 g were used. Fish in the infected group (group I) were intraperitoneally injected with S. iniae at 3.3 x 10(5) colony forming unit (CFU) in 0.1 mL level to the fish. The other group (group II) was subjected to handling stress near the infection. The control group was constituted by providing optimum conditions. On days 7, 14, and 21, blood samples were taken from the caudal veins of the fish under the appropriate anesthesia. The samples were examined on the basis of APPs, C-reactive protein (CRP), fibrinogen (FB), serum amyloid A (SAA), and transferrin (TF) and the changes in the plasma values were recorded. The internal and external symptoms seen during the examinations were detected as follows: the color concentration in 1-2 days in the infected groups, irregularity and retardation in the movements of the fish, hyperemic spots on the skin, and bloody effusion in the internal organs. In both of the infected groups, the CRP and SAA plasma values increased on days 7, 14, and 21 (P < 0.05). Remission was observed in the plasma TF levels in the first week; however, aft er the second week the levels reached normal values. Decreases in the FB levels of all of the samples were detected. Based on the data acquired in this study, it was concluded that changes in the plasma levels of the APP members can be used as a significant bioindicator in the pathogenesis of the disease in fish infections.

The compensatory growth response of the European sea bass (Dicentrarchus labrax) that faced cycling starvation and restricted ration was assessed. Juveniles (10.5g) were stocked into 15 tanks at a density of 25 fish per tank. Five different feeding regimes were tested on triplicate groups of fish: CSatiation: control fed for 60days without deprivation, CRestricted: 25% restricted feeding, S-R: 1day starvation then 4days CRestricted feeding, R-F: 1day CRestricted feeding then 4days CSatiation feeding, and, finally, S-F: 1day starvation then 4days CSatiation feeding. The specific growth rate of fish in the CSatiation (2.5 +/- 0.06%day-1), S-F (2.5 +/- 0.11%day-1) and R-F (2.4 +/- 0.18%day-1) were significantly higher than that of CRestricted (2.2 +/- 0.05%day-1) or S-R (2.0 +/- 0.01%day-1). Fish in S-F group were able to achieve catching up with the CSatiation. There was no significant difference in feed conversion rates but R-F and S-F consumed approximately 34% more feed than CSatiation following the first re-feeding day. Although, the highest lipid content was observed in CSatiation (14.4%), S-R (33.3% dry matter) had the highest water content compared with the CSatiation and CRestricted (37.8% and 36.9% dry matter respectively). In conclusion, it may be concluded that sea bass has rapid response to cycling starvation/re-feeding and that a 25% restricted feeding ratio is insufficient to invoke a compensatory growth response in sea bass.

Gürsov, Mujde; Taner, Guler
In this study, paleontological and biostratigraphic characteristics of the Paleogene geologic units outcropping between Kuscu and Macun villages located around Temelli district, Polatli, Ankara. We have examined the patterns of Pelecypoda and Gastropoda samples. Seven measured stratigraphic section from the west of Macun village to east of Kuscu village, which contains the Pelecypoda and Gastropoda patterns, reach total thickness of 52 metres. As a result of field studies, seven species belongs to class of Pelecypoda and one of the new sixteen species belongs to class of Gastropoda have been described. Considering paleogeographic distribution and biostratigraphy of described fauna, it is quite proper to propose that they represent Thanetian age and can be interpreted as belonging to Kirkkavak Formation. Furthermore, the paleoecologic characteristics of the fauna strongly suggests that the shallow and temperate coastal marine facial conditions were prevalent at the region during that time span.

Emiroglu, Oya Nuran; Karatay, Gulnaz
Introduction: Falls in the elderly are a significant problem with consequences that may lead to death. Although many studies have been conducted regarding falls in the elderly, little is known of their own perceptions and experiences of falling. The purpose of this study was to better understand how the elderly living in institutions understand and perceive their experiences of falling. Materials and Method: A qualitative design was used based upon van Manen's phenomenological approach. Interviews were conducted with 22 elderly using a purposive sampling method. Van Manen's data analysis approach was used to analyze the data derived from the interviews. Results: Outcomes of this study showed that there were three main perceptions about falls for the elderly: Participants acknowledged falling as a painful experience and that falls should be expected in old age. Still others understood that life goes on but with new areas of concern which will require their attention and care. Conclusion: The results of this study show that all health care personnel, particularly the nurses who care for the elderly in an institutional environment, need to adopt an individualized and empathetic approach to those in their care. Falls happen often and can be fatal to the elderly. Thus it is very important for all health care professionals working with the elderly to be fully informed and involved in ensuring that their patients practice safe behaviors to guard against falls. Care should also be taken to ensure that their living environment is safe and secure.

The purpose of this study was to test the effects of a multistimulant home-based program on cognitive function among older adults. This study was conducted in northeastern Turkey between March and June 2010. It was planned as an experimental versus control two-group design and carried out on 96 (intervention group = 48, control group = 48) participants. The intervention and control groups were similar regarding sex, education, partner status, and continuous drug use. Data were collected with a Standardized Mini Mental Test, the Geriatric Depression Scale (GDS), and the Beck Anxiety Scale. Each senior received a total of 10 home visits on a once-per-week basis. Results for the intervention group showed that the Mini Mental State Test scores of the participants had statistically increased, and the Beck Anxiety and the GDS scores showed a decrease. The study found an association between the multistimulant home-based intervention program and cognitive function.

The risk of fish pathogen transmission via eggs can be reduced by disinfection in ozonated seawater. The aim of this study was to determine the suitable conditions for ozone disinfection of the eggs of gilthead seabream Sparus aurata, sea bass Dicentrarchus labrax, red porgy Pagrus pagrus, and common dentex Dentex dentex. The eggs were disinfected with a concentration (C) of 0.5 mg of ozone/L of water at four different exposure times (T = 2, 4, 8, and 16 min). The hatching rate was determined in triplicate for each treatment. Bacterial colonies were counted on tryptic soy agar and thiosulfate-citrate-bile salts-sucrose agar. At the end of the experiment, bacterial load and hatching rate were assessed together to determine the optimal ozone treatment values, which were estimated in CT units (i.e., C [= 0.5 mg/L] x T [min]). Optimal values were CT 2-4 (T = 4-8 min; 18 degrees C) for gilthead seabream and red porgy, CT 2 (T = 4 min; 18 degrees C) for common dentex, and CT 4 (T = 8 min; 15 degrees C) for sea bass.

Four cyano complexes, [Ni(N-bishydeten)Ni(CN)(4)](n) (c1), [Cu(N-bishydeten)(2)][Ni(CN)(4)] (c2), [Zn-2(N-bishydeten)(2)Ni(CN)(4)](n) (c3), and [Cd(N-bishydeten)(2)][Ni(CN)(4)] (c4), have been synthesized and characterized by FT-IR, elemental, and thermal analyses. The structures of c2 and c4 were determined by single-crystal X-ray diffraction studies; both structures contain isolated cations and anions. The c2 consists of [Cu(N-bishydeten)(2)](2+) with octahedrally coordinated Cu-II and diamagnetic [Ni(CN)(4)](2-), but c4 consists of [Cd(N-bishydeten)(2)](2+), in which Cd-II is eight coordinate with two tetradentate N-bishydeten and diamagnetic [Ni(CN)(4)](2-). The value of the shape measure S (degrees) indicates that the coordination geometry around Cd-II lies along D-2d [dodecahedron; (dd)], C-2v [bicapped trigonal prism; (btp)], and D-4d [square antiprism; (sap)] but close to D-2d and D-4d. Variable temperature magnetic susceptibility measurements of c1 and c2 show the presence of little antiferromagnetic interaction below 20 K. Thermal analyses reveal that first neutral N-bishydeten and then cyano ligands were liberated from the complexes.

Eleven plant species were collected from the vicinity of lead-battery plant in the city of Gaziantep, Turkey. Lead, cadmium and copper concentrations in the soil and leaves of plants were determined by atomic absorption spectrometry. Lead, Cd and Cu concentrations in the soil samples taken from battery area were found to be in the ranges of 304 similar to 602, 0. 4 similar to 0. 44 and 31 similar to 37 mg . kg(-1), respectively. Significantly increased lead concentration up to 2 750 mg . kg(-1) was found in the leaves of Eleagnus angustifolia L. plant. The lead concentrations in the other plant leaves taken from 50 m around battery factory followed the order Ailanthus altissima > Morus sp. > Juglans regia L. > Ficus carica L. > Cydonia oblonga Miller > Prunus x domestica L. The plants, Populus nigra L., Eleagnus angustifolia L. and Salix sp. were found useful for Cd, and the plant, Eleagnus angustifolia L. for Pb, to be considered as potential biomonitor. Especially, leaves of trees and plants taken from the distance of 50 m from battery plant have relatively higher Pb concentrations. Therefore, people who and animals which live in this area and benefit from these soil and plants have vital risks.

Salmo trutta caspius T., 1954 is a native to Caspian Sea and is an important fish species due to its aquaculture potential, economic value and high marketability. The aims of this study were to determine hatching rate, body and yolk weight at hatching, the growth rate during the yolk absorption and yolk conversion efficiency of S. I. caspius larvae. Studies were further extended to determine the relationships between length, total wet weight, dry yolk body weights of alevins and degree-days. Results revealed that the mean wet weight was 16.78 +/- 2.17 mg (n = 10) at hatching and reached 52.62 +/- 3.55 mg just before the swim-up stage. The mean dry weights of the body and yolk sac were 2.36 +/- 0.28 mg and 10.67 +/- 0.67 mg at hatching and 7.21 +/- 0.71 mg and 2.57 +/- 0.62 mg at swim-up stages, respectively. The mean body dry matter and water content of the larvae were 33.10% and 66.90% at hatching and 15.46% and 84.54% of the total biomass at swim-up stages, respectively. Our results indicated that dry yolk, total larval weights and dry matter of the larvae decreased, while body weight and water content increased with degree-days. The growth of larva, yolk sac absorption and yolk conversion efficiency were calculated as 0.18 mg/day, 0.23 mg/day and 0.60, respectively. The data collected during these studies contribute to the management practices of the stocks of this species.

The concentrations and varieties of benzo[a]pyrene were determined in Turkish foodstuffs including grilled meat and chicken samples by high performance liquid chromatography-mass spectrometry (HPLC-MS). The parameters that are thought to affect the response in the HPLC-MS analysis were optimized. The optimized conditions were found to be 0.75 mL min(-1) for flow rate of mobile phase, 45 mu L for injection volume, 55 degrees C for column temperature and 140 V for fragmentor potential. The optimized method was applied for the determination of benzo[a]pyrene concentrations in grilled meat and chicken foods. The obtained concentrations were found in the range of 2.7-8.3 mu g kg(-1) for the normal grilled meat and chicken samples and 72-138 mu g kg(-1) for over-grilled samples. The results showed that the concentrations of benzo[a]pyrene were significantly dependent on the kind of meat and the cooking time and source. The limits of detection and quantitation were found to be 0.7 and 2.33 mu g L-1, respectively.

Cisplatin (CP) is one of the most effective cancer chemotherapeutic agent used against various solid tumors. This study was designed to investigate the antioxidant effects of Grape Seed Extract (GSE) on CP induced oxidative damage in rabbit kidney. The material of study was consist of 18 male New Zealand rabbit. Animals were divided into 3 groups. The first group was administered a single intraperitoneal (i.p.) close of 0.9% saline. The second group of rabbits was treated with CP (a single i.p. dose of 5 mg kg(-1) body weight); The third group of rabbits was treated with GSE by gavage at the dose of 250 mg kg(-1) body weight for 6 consecutive days before and 6 consecutive days after a single i.p. CP injection. As a result of CP administration, kidney function tests; urea, BUN (Blood Urea Nitrogen) and creatinine levels were increased (p<0.001). It was observed that CP increase malondialdehide (MDA) levels, the most important indicator of oxidative damage and decreased the activity of catalasc (CAT). Administration of CP did not caused statically a change in glutathione (GSH) levels and glutathione peroxidase (GSH-P-x) activity (p>0.05). GSE treatment has high levels of MDA to compared to normal levels (p<0.001) but not an increase in CAT (p<0.05). In CP treatment group, severe acute tubular necrosis was seen. It was determined that in CP+GSE group mild degenerative changes were received instead of acute tubular necrosis. GSE has been found to be partially protective effect against CP induced biochemical and histopathological changes in rabbit kidney.
