    (Medwell Online, 2010) Kaygusuz, Sedat; Osman-Arikan; Azkur, Kursat; Simsek, Hulya; Gazyagci, Serkal; Muluk, Nuray; Ertek, Mustafa
    Tularemia is a zoonotic disease caused by Francisella tularensis which can be transmitted to humans by tick bites contaminated water handling infected materials and inhalation. The different clinical types are ulceroglandular, glandular, oropharyngeal, oculoglandular, typhoidal and pneumonic tularemia. Streptomycin and tetracycline are commonly used to treat this infection. In this study approched other patients after the suspected tularemia patient attended to Kirikkale University, Faculty of Medicine with the servical mass complaint at January 2010. To find the reservoir for tularemia, laboratory research was carried on the mice. suspected to be infected with Francisella tularensis in the town of infection.

    Intralesional Avirulent Bacillus Calmette-Guerin Injection as a Promising Method for the Treatment of Tuberculosis Verrucosa Cutis
    (Karger, 2022) Gunduz, Ozgur; Kocak, Gulsah; Kacmaz, Birgul; Devrim, Tuba; Simsek, Hulya
    Cutaneous involvement is a relatively uncommon manifestation of tuberculosis (TB), particularly outside the endemic regions. Cutaneous TB manifests itself in various clinical forms, depending on the host's immune status and mode of transmission. Nonetheless, the same treatment regimen is recommended for every subtype. Tuberculosis verrucosa cutis (TBVC) is a specific subgroup in which the affected persons are usually healthy adults who are vaccinated or exposed to mycobacteria during their occupational activities. These patients have the ability to launch a strong cellular immune reaction against mycobacteria. In this article, we present an elderly patient with a 4-year history of TBVC who was treated with intralesional injection of avirulent Bacillus Calmette-Guerin (BCG) and report our clinical observation on the inflammatory and healing process of the patient's lesion following the intralesional BCG injection.

    Phosphorus-nitrogen compounds. Part 35. Syntheses, spectroscopic and electrochemical properties, and antituberculosis, antimicrobial and cytotoxic activities of mono-ferrocenyl-spirocyclotetraphosphazenes
    (Royal Soc Chemistry, 2016) Okumus, Aytug; Elmas, Gamze; Cemaloglu, Resit; Aydin, Betul; Binici, Arzu; Simsek, Hulya; Hokelek, Tuncer
    The reactions of octachlorocyclotetraphosphazene, N4P4Cl8, with N-alkyl-N-mono-ferrocenyldiamines, FcCH(2)NH(CH2)(n)NHR1 [n = 2, Fc = ferrocene, R-1 = Me (1); n = 2, R-1 = Et (2) and n = 3, R-1 = Me (3)], led to the formation of monoferrocenyl-spirocyclotetraphosphazenes (4-6). When the reactions were carried out with excess pyrrolidine, morpholine and 1,4-dioxa-8-azaspiro[4,5] decane (DASD), the fully substituted products (4a-6c) were obtained in high yields. The structures of all the phosphazene derivatives were characterized by MS, FTIR, H-1, C-13 and P-31 NMR, HSQC and HMBC techniques. The crystal structures of 4a and 5a were determined by X-ray crystallography. The electrochemically reversible one-electron oxidation of Fc redox centers was observed for cyclotetraphosphazenes. The fully substituted phosphazenes (4a-6c) were evaluated for their antituberculosis activity against reference strain Mycobacterium tuberculosis H37Rv, and compounds 4a-6a and 5c were found to be active. The antibacterial activities of phosphazenes 4a-6c against G(+) and G(-) bacteria and their antifungal activities against yeast strains were carefully scrutinized. The results indicate that compounds 4a-6a, 6b, 4c and 5c are very effective against yeast strains. The anticandidal activities of 6a and 6b make them promising anticandidal agents. The interactions of these compounds with plasmid DNA and their cytotoxic activity against L929 fibroblast and DLD-1 colon cancer cell lines were also investigated.
