    1-Benzyl-3-(2-phenethyl)benzimidazolium bromide monohydrate
    (Int Union Crystallography, 2005) Akkurt, M; Karaca, S; Kücükbay, H; Orhan, E; Büyükgüngör, O
    The title compound, C22H20N2+center dot Br-center dot H2O, was synthesized from 1-benzylbenzimidazole and 2-bromoethylbenzene in dimethylformamide. The dihedral angle between the two phenyl rings is 70.6 ( 1)degrees. These phenyl rings make dihedral angles of 52.99 ( 9) and 83.03 ( 8)degrees with the benzimidazole ring system. The crystal structure is stabilized by intermolecular C-H center dot center dot center dot Br and O-H center dot center dot center dot Br hydrogen-bond interactions.

    1-benzyl-3-[2-(1-piperidinio)ethyl]benzimidazolium dichloride monohydrate
    (Int Union Crystallography, 2005) Karaca, S; Akkurt, M; Yilmaz, Ü; Küçükbay, H; Büyükgüngör, O
    The title compound, C21H27N32+.2Cl(-).H2O, was synthesized from 1-benzylbenzimidazole and 2-chloroethylpiperidine hydrochloride in dimethylformamide. In the cation, the benzimidazole ring is connected to the piperidine ring by an ethylene group. The crystal structure is stabilized by O - H ........ Cl, N - H.......Cl, C - H........ O and C - H........ Cl hydrogen-bonding interactions.

    Amyloidosis cutis dyschromica: A case treated with acitretin
    (Wiley, 2005) Ozcan, A; Senol, M; Aydin, NE; Karaca, S
    We report a case of amyloidosis cutis dyschromica with diffuse postinflammatory-type hypo- and hyperpigmentation all over the body. The diagnosis was confirmed with routine light microscopic and immunohistochemical staining methods. The patient was treated with acitretin with a good response.

    A case of Lupus vulgaris with unusual location
    (Japanese Dermatolgical Assoc, 2003) Senol, M; Ozcan, A; Mizrak, B; Turgut, AC; Karaca, S; Kocer, H
    Tuberculosis (TB) is one of the oldest diseases of our planet; today, it still is a serious medicosocial problem in both developing and developed countries. Cutaneous tuberculosis is part of the small percentage of extrapulmonary forms of the disease and has considerable morphological variability. It is often confused with various cutaneous disorders and some other granulomatous processes of the skin. Here, we present a case of long-standing and atypically-located lupus vulgaris in an old man. The patient was successfully treated with triple antituberculous therapy.

    A case of sporotrichosis treated with itraconazole
    (Taylor & Francis Ltd, 2003) Ozcan, A; Senol, M; Karaca, S; Sener, S; Polat, M; Ozerol, IH
    Lymphocutaneous sporotrichosis is caused by Sporothrix schenckii, a dimorphic fungus commonly existing on decaying plants and in the soil. The fungus has a worldwide distribution but is more prevalent in temperate and tropical climates. Infection may result from traumatic inoculation of contaminated material such as soil, hay, moss, plant debris, splinters, thorns and barbs. Inoculation is also possible through some animal scratches and bites. We describe a typical case of lymphocutaneous sporotrichosis, which was confirmed by clinical, histological and microbiological features. The patient was successfully treated with 400 mg daily systemic itraconazole for 4 months.

    A comparative study of superoxide dismutase, catalase, and glutathione peroxidase activities and nitrate levels in vitiligo patients
    (Wiley, 2005) Hazneci, E; Karabulut, AB; Öztürk, Ç; Batçioglu, K; Dogan, G; Karaca, S; Esrefoglu, M
    Background Several groups have shown the involvement of oxidative stress in the pathophysiology of vitiligo. Methods In this study, we examined the erythrocyte and plasma activities of glutathione peroxidase and Cu/Zn superoxide dismutase, plasma nitrite/nitrate levels, and erythrocyte catalase activity in 23 vitiligo patients and 25 controls. Results The results show that erythrocyte superoxide dismutase activity and plasma nitrite/nitrate levels are high in vitiligo patients. Conclusions Our study confirms that oxidative stress is involved in the pathophysiology of vitiligo, as indicated by the high levels of erythrocyte superoxide dismutase activity and plasma nitrite/nitrate.

    Dichlorobis[1-(2-ethoxyethyl)-1H-benzimidazole-?N3]nickel(II)
    (Int Union Crystallography, 2005) Akkurt, M; Karaca, S; Küçükbay, H; Orhan, E; Büyükgüngör, O
    The title compound, [NiCl2(C11H14N2O)(2)], was synthesized from 1-(2-ethoxyethyl)benzimidazole and nickel dichloride in ethanol and is isostructural with its cobalt analogue. It shows a distorted tetrahedral geometry about Ni-II, involving two Cl atoms and two benzimidazole N atoms. The crystal structure is stabilized by C-H...Cl and C-H...O interactions.

    Mercapto-N-phenylformimidoyl-1-ethyl-3-( 2-morpholinoethyl)benzimidazolinium inner salt
    (Int Union Crystallography, 2005) Akkurt, M; Karaca, S; Küçükbay, H; Yilmaz, Ü; Büyükgüngör, O
    In the title compound {alternative name: [1-ethyl-3-(2-morpholinoethyl) benzimidazoliumyl]( phenylimino) methanethiolate}, C22H26N4OS, the morpholine ring has a chair conformation. The dihedral angle between the benzimidazole ring system and the phenyl ring is 0.5 (2)degrees. The crystal structure is stabilized by intermolecular C - H (...) O contacts.
