  Anesthetic and sedative efficacy of peppermint (Mentha piperita) and lavender (Lavandula angustifolia) essential oils in blue dolphin cichlid (Cyrtocara moorii)

  Can, Erkan; Sümer, Esma

  The use of different essential oils (Eos), which are considered as a good alternative to synthetic materials, is increasing day by day in fish species. Nevertheless, studies on the anesthetic effect of peppermint Eo (Mentha piperita; MPEo) and lavender Eo (Lavandula angustifolia; LAEo) are scarce. In the present study, the effective concentrations of three anesthetic materials (MPEo, LAEo, and MS-222) were previously determined in the concentrations range of 100–400 ppm in Cyrtocara moorii juveniles (4.92 ± 1.03 g and 7.13 ± 1.22 cm) with the criteria of appropriate induction time (AIt) and ready recovery time (RRt) (Trial 1). Afterwards, four different groups were established at three different sedative concentrations (10, 20, and 30 ppm and a control group without anesthetic additive) for transporting (Trial 2). The study concluded that MPEo and LAEo can be used as anesthetic and sedative agents in tropical fish species safely. The use of 100 µL L–1 (183.5 s AIt and 227.8 s RRt) and 300 µL L–1 (109.2 s AIt and 420.0 s RRt) MPEo and LAEo, respectively, was sufficient for deep anesthesia, whereas concentrations in the range of 10 to 30 µL L–1 are recommended for fish transport.

  The protective effects of chrysin and flunixin meglumine against excess copper in male rats

  Seven, Pinar Tatli; Baykalir, Burcu Gül; Seven, Ismail; Ak, Tuba Parlak; Başak, Neşe; Güllüoglu, Hakan

  Thirty-six Sprague Dawley male rats were housed in individual cages and randomly divided into six groups: Control, copper sulfate (Cu; 500 ppm body weight (BW)/day), flunixin meglumine (FM; 2.2 ppm BW/day), chrysin (chrysin; 50 ppm BW/day), copper sulfate + FM (Cu + FM; 500 ppm BW/day of copper sulfate and 2.2 ppm BW/day of FM), and copper sulfate + chrysin (Cu + Chrysin; 500 ppm BW/day of copper sulfate and 50 ppm BW/day of chrysin). Feed intake (FI) in the Cu + Chrysin group significantly increased in comparison with that of the Cu group (P < 0.01). Cu excess significantly increased malondialdehyde, indicating oxidative stress. Chrysin and FM administration significantly decreased malondialdehyde levels and increased the superoxide dismutase and catalase activities in the liver and kidney tissues (P < 0.001). Serum TNF-α levels were significantly lower in the Cu + FM and Cu + Chrysin groups in comparison to the Cu group (P < 0.001). It was seen that FM and chrysin treatments alleviated degeneration, necrosis, and apoptosis in the liver and kidney tissues of the Cu-treated rats. Chrysin appeared to ameliorate the adverse effects on FI and liver and kidney tissues by scavenging where the free radicals are located and increasing the activity of antioxidants.

  Effects of essential oil compounds on survival of Listeria monocytogenes and Escherichia coli O157:H7 in cig kofte

  Dikici, Abdullah; Ilhak, Osman Irfan; Çalicioglu, Mehmet

  This study was undertaken to evaluate the effects of some essential oil compounds for the inactivation of Listeria monocytogenes and Escherichia coli O157:H7 in cig kofte. In experiment 1, a cig kofte batch was inoculated with high levels of E. coli O157: H7 or L. monocytogenes (7.00 log(10) cfu/g) and the batches were divided into 6 groups. Each group was treated with 18 mL/kg of normal saline, cineole, limonene, carvone, linalool, or eugenol. Treatment with carvone, linalool, and eugenol resulted in a significant (P < 0.05) decrease in the numbers of both pathogens. In experiment 2, the cig kofte was inoculated with the same pathogens and each group was treated with 0 (control), 20, 22.5, and 25 mL/kg of eugenol. Increases in concentration did not cause a difference in pathogen reduction. The results showed that eugenol, carvone, and linalool can be used for the inactivation of E. coli O157: H7 and L. monocytogenes in cig kofte or similar foods.

  Determination of acute phase proteins aft er experimental Streptococcus iniae infection in tilapia (Oreochromis niloticus L.)

  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.
