Öğe EFFICACY OF MASS TRAPPING OF TOMATO LEAFMINER (TUTA ABSOLUTA) WITH DIFFERENT TYPES AND COLOURS OF TRAPS IN OPEN-FIELD TOMATO(Corvinus Univ Budapest, 2019) Polat, B.As a limiting factor on tomato production, tomato leafminer Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) has recently been considered as the main tomato pest. Different control methods should be considered for integrated pest management. This study was carried out to control T. absoluta by using pheromones and traps of five different colours (red, yellow, blue, white, black) and three different types (ferolite, water pan, roll) in combination at trial plots in Dardanos and Dumrek and Ciplak villages in canakkale province, Turkey. A randomized plot experimental design was implemented and traps were controlled and counted twice a week. Ferolite traps were determined to have the most success in capturing adults, followed by water and roll traps. The highest number of adults was captured with the colours black and white regardless of trap type, whereas the lowest number of adults was captured with yellow traps. It was observed upon comparing the capture rates of T. absoluta adults subject to trap type that 49% of the adults were counted in the ferolite traps. Water pans and roll traps followed the ferolite trap with 38% and 13%, respectively. Results indicate that mass trapping is effective in reducing the pest population in open-field tomato cultivars.Öğe Protective effect of an L-type calcium channel blocker, amlodipine, on paracetamol-induced hepatotoxicity in rats(Sage Publications Ltd, 2018) Kaya, H.; Polat, B.; Albayrak, A.; Mercantepe, T.; Buyuk, B.Paracetamol (P), one of the most popular and commonly used analgesic and antipyretic agents, causes hepatotoxicity in overdoses. Amlodipine (AML), an L-type calcium channel blocker, has been shown to have anti-inflammatory activity by reversing the effect of calcium in the inflammation pathogenesis. In this study, the hepatoprotective activity of AML on P-induced hepatotoxicity was evaluated. Thirty male albino Wistar rats were divided into five groups: (1) control, (2) 2 g/kg of P, (3) 2 g/kg of P + 5 mg/kg of AML, (4) 2 g/kg of P + 10 mg/kg of AML, and (5) 10 mg/kg of AML. Some liver enzymes, oxidative parameters, cytokine mRNA expressions, histopathology, and immunohistochemical studies were performed in liver and blood samples. The serum levels of alanine aminotransferase and aspartate aminotransferase and the mRNA expression of tumor necrosis factor-alpha (TNF-alpha) and transforming growth factor-beta in the liver tissues were significantly increased in the group treated with P. The superoxide dismutase and glutathione parameters decreased and malondialdehyde levels increased in the livers of the rats treated with P. All these parameters were increased with both doses of the AML similar to the control group. A histopathological examination of the liver showed that AML administration ameliorated the P-induced inflammatory liver damage. In immunohistochemical staining, the expression of TNF-alpha in the cytoplasm of the hepatocytes was increased in the P group but not in other treatment groups when compared to the control. In conclusion, AML treatment showed significant protective effects against P-induced hepatotoxicity by increasing the activity of antioxidants and reducing inflammatory cytokines.
