    Effect of cutaneous leishmaniasis treatment on serum adenosine/ deoxyadenosine deaminase activities
    (Chemical Publishing Co., 2012) Çulha, Gülnaz; Berköz, Mehmet; Yalin, Serap; Gülkan, Burcu
    Adenosine deaminase is an enzyme present in a great number of plants and animals, found from simple intervebrates to human beings. Adenosine deaminase and deoxyadenosine deaminase activities increase substantially during mitogenic and antigenic responses of lymphocytes and conversely lymphocytes blastogenesis. Various diseases characterized by the alteration of cell-mediated immunity can be effected by the serum activity of adenosine deaminase. Cutaneous leishmania is an intracellular parasite that targets and multiplies within phagocytic cells of the innate immune system such as the macrophage, dendritic cell and neutrophil. In this study, we investigated the role of treatment on adenosine deaminase and deoxyadenosine deaminase activities in the cutaneous leishmaniasis patients. For this aim, 25 treated cutaneous leishmaniasis patients, 19 untreated patients and 25 healthy control subjects were enrolled in this study. The clinical diagnosis was parasitologically confirmed Giemsa stain and by culture NNN medium. Adenosine deaminase and deoxyadenosine deaminase activities were measured spectrophotometrically by the method of Giusti. Serum adenosine deaminase and deoxyadenosine deaminase activities were higher in cutaneous leishmaniasis patients than the controls and also, adenosine deaminase and deoxyadenosine deaminase activities decreased in treated patients as compare with non-treated cutaneous leishmaniasis patients. According to these results, it is suggested that evaluation of adenosine deaminase activity in serum of patients with cutaneous leishmaniasis could be considered a useful monitoring tool for their infection status. Therefore, adenosine deaminase can be a predictive and sensitive parameter of leishmaniasis treatment.

    Investigation of Brucella seroprevalence in human and livestocks in Igdır, Turkey
    (Yuzuncu Yil Universitesi Tip Fakultesi, 2016) Bora, Gülhan; Akkoyunlu, Yasemin; Berköz, Mehmet; Açıkgöz, Güneş; Berktaş, Mustafa; Altındağ, Fikret; Bora, Aydoğan
    Brucellosis is a zoonotic disease of worldwide and still remains endemic in some developing countries, especially in Turkey. Milk is the main food product serving as a vector for Brucella. In this study we aimed to investigate the seroprevalence of human and animal brucellosis. The study group consisted of 358 subjects who had high risk occupations of animal breeder and farmer. The test results were interpreted and titers equal or in excess of 1/40 were considered significant. 189 farm animals were incorporated to our research. Among these animals, 104 of them were sheep and goat and 85 of them were cattle. The Brucellosis Milk Ring Test was used to test raw milk samples collected the selected herds in the study area. The seroprevalence of human brucellosis was 6.7%. Seroprevalence of animal brucellosis was found as 22.75% in livestocks. This study is important for being the first study in recent years that demonstrates the Brucella seropositivity rates in Igdır Province. This high seropositivity in our region may depend on the high rates of animal brucellosis; those of which were inadequate under control by veterinary and by vaccination and people who consume the milk by without boiling. © 2016 Yuzuncu Yil Universitesi Tip Fakultesi.
