    Visceral leishmaniasis (VL) has now been recorded from 38 provinces of Turkey. Twenty-one VL cases were reported within six years from settlements located in most northeastern Turkey and we therefore aimed to carry out an entomological and seroepidemiological survey in this new focus for clarifying risk factors. Blood samples from 290 children and 165 dogs were collected. Sera samples were investigated for anti- Leishmania antibodies using indirect fluorescent antibody test. Sand fly collection for determining the fauna and seasonal activity was performed in all settlements by CDC light traps between June and September 2006. Although no seropositive child was detected during the survey the overall seroprevalence rate of canine leishmaniasis was found as 7.2%. A total of 4154 sand flies were collected and 10 species of genus Phlebotomus were identified belonging to A. dlerius, Larroussius, Paraphlebotomus and Phlebotomus subgenera. Among them Phlebotomus kandelakii s.l. (55.44%), Phlebotomus balcanicus (12.62%) and Phlebotomus neglectus (4.40%) was detected as probable vector species for this new focus. The poor sanitation, very high population size of sand flies, probably because of very short season, no control measures for sand flies as well as dogs, and presence of microclimate suitable for sand flies were considered as main risk factors in the area. © 2015 Elsevier B.V.

    The effect of Paracetamol exposure on hepatic and renal tissues during statin usage
    (De Gruyter, 2019) Aksun S.; Gökcimen A.; Kahyaoglu F.; Demirci B.
    Objective: Statins and Paracetamol have widespread use in clinic and both drugs possess similar side effects; therefore, we investigated if drug-interaction occurs when the combination of these two drugs is used during therapy. Materials and methods: A total of 32 (12-15 months old) grown-up male rats were divided into four groups: Control group, RSV group (10 mg/kg Rosuvastatin/daily), APAP group (50 mg/kg Paracetamol/5 days/weekly), RSV + APAP (10 mg/kg Rosuvastatin/daily + 50 mg/kg Paracetamol/5 days/weekly). At the end of 8 weeks of chronic treatment, the blood and tissue samples were taken under the Ketamine and Xylasine anesthesia (50 mg/kg and 5 mg/kg, respectively). Results: In the liver, sinusoidal dilatations, pyknotic nuclei and hemorrhagic foci are more frequently seen in the group receiving combination therapy; although serum liver functions among groups were not significantly different. Kidney histopathologic alterations in APAP and RSV + APAP groups were found more distinct than in RSV alone group. Inducible nitric oxide synthase activity was highly increased with combination therapy in liver and kidney tissues. Conclusion: RSV-Paracetamol interaction may occur as an important drug interaction histopathologically even before it is manifested biochemically in the clinic. © 2019 De Gruyter. All rights reserved.
