Öğe Assessment of toxoplasma IgG avidity test results in pregnant women(Saudi Med J, 2005) Ozekinci, T; Suay, A; Karasahin, O; Akpolat, N; Mete, M; Atmaca, S[Abstract Not Available]Öğe Comparison of slime production under aerobic and anaerobic conditions(Faculty Press, 1996) Atmaca, S; Elci, S; Gul, KA total of sixteen clinical isolates of coagulase-negative staphylococci were investigated for slime production by the test tube and Congo red agar method. In order to determine the role of oxygen in slime production, Staphylococcus epidermidis culture plate assay was performed under aerobic and anaerobic conditions. Findings revealed that the slime production was less under the anaerobic conditions.Öğe Differential production of slime by Staphylococcus saprophyticus under aerobic and anaerobic conditions(Lippincott Williams & Wilkins, 2000) Atmaca, S; Elci, S; Akpolat, NO[Abstract Not Available]Öğe Distribution of HBV DNA according to age group in the Diyarbakir region (southeast Turkey)(W B Saunders Co Ltd, 2003) Ozekinci, T; Ozerdem, N; Atmaca, S; Elçi, S[Abstract Not Available]Öğe Effect of TSB supplemented with various concentration and combination of glucose and EDDA on slime production in Staphylococcus epidermidis(Mbr Press Inc, 1997) Elci, S; Atmaca, S; Gul, K; Akbayin, HSlime production by S.epidermidis was investigated in TSB and TSB supplemented with glucose, EDDA and combinations of glucose and EDDA in various concentrations. Fourteen clinically relavent strains were assayed and cultivated in these media at different incubation periods. The optical density scores obtained from ELISA autoreader were evaluated statistically. Most of S.epidermis strains were capable of switching to high level slime production when subjected to these media. Particularly, the low slime producer group of S.epidermis was stimulated to high level slime production by these media and increasing incubation period decreased slime production differences among the low, moderate and strong slime producer groups.Öğe Effect of zinc concentration in Mueller-Hinton agar on susceptibility of Pseudomonas aeruginosa to meropenem(Lippincott Williams & Wilkins, 1998) Atmaca, S[Abstract Not Available]Öğe The effects of magnesium, calcium and EDTA on slime production by Staphylococcus epidermidis strains(Springer, 2003) Akpolat, NÖ; Elçi, S; Atmaca, S; Akbayin, H; Gül, KEffect of magnesium, calcium and EDTA on slime production by 15 slime-positive and 13 slime-negative Staphylococcus epidermidis strains isolated from various clinical specimens was determined. The slime production on tryptic soy broth was significantly enhanced after addition of 128 mumol/L Mg2+. Similarly, the addition of Ca2+ caused a significant increase in slime production of all tested strains when concentration of Ca2+ exceeded 64 mumol/L. In contrast, in the presence of EDTA the slime production by all strains was significantly reduced. Hence Ca2+ and Mg2+ increase slime production of S. epidermidis. This finding is important in the context of the pathogenesis of biomedical implant infections caused by S. epidermidis.Öğe Lichen planus and hepatitis c virus infection: an epidemiologic study(Wiley, 2004) Harman, M; Akdeniz, S; Dursun, M; Akpolat, N; Atmaca, SThe reported prevalence of hepatitis C virus (HCV) infection in patients with lichen planus (LP) shows variations from different regions. The aim of this study was to investigate the prevalence of HCV infection in patients with LP, in Diyarbakir region of Turkey. A total of 128 patients with LP and 128 healthy controls were detected for HCV infection, using a third generation enzyme-linked immunosorbent assay. Eight of 128 patients (6.25%) with LP were found to have anti-HCV antibodies, whereas only one patient (0.78%) in control group was found to have anti-HCV antibodies. A statistically significant difference was found between LP and control group (p < 0.001). In conclusion, the coexistence of HCV infection and lichen planus is more than coincidental, and it is appropriate to screen all patients with lichen planus for HCV infection.Öğe Listeria monocytogenes in products of animal origin in turkey(Springer, 2004) Akpolat, NÖ; Elci, S; Atmaca, S; Gül, KA study was carried out on 430 samples of different foodstuffs (soft cheese, raw chicken, minced beef, sausage, fish) and 400 carcase samples (sheep, young and adult cattle) for screening of Listeria monocytogenes. It was found that only one of the samples contained L. monocytogenes at > 10(3) cfu/ml in the initial examination, but another 42 samples contained L monocytogenes following an enrichment process. L. monocytogenes was isolated most frequently from raw chicken samples (18%), but was not isolated from sausage samples. Forty-three isolates were defined as serotypes by using Bacto-Listeria-O-antisera Type 1 (Difco 2300-50-2) and Type 4 (Difco 2301-50-1) except that Type poly was not used. For these reasons, all isolates were classified as type 1 or type 4 and the other was termed untypeable. Twenty-one samples were type 1, 17 were untypeable, and 5 were both serotype 4 and untypeable.Öğe The management of lichen planus with low-molecular-weight heparin (enoxaparin)(Wiley, 2005) Akdeniz, S; Harman, M; Atmaca, S; Yaldiz, MThe aim of this study is to evaluate the efficiency of low-dose, low-molecular-weight heparin (enoxaparin) in the treatment of lichen planus (LP). Twenty-four patients clinically and histopathologically diagnosed as LP with intense pruritus were treated with 3 mg of enoxaparin (Clexane((R))), subcutaneously once a week for 4-14 weeks. Complete remission was observed in 20 of 24 patients (83%) who had widespread cutaneous involvement, but no or minimal effect was observed in four of 24 patients, three of whom had chronic hypertrophic LP. Low-dose enoxaparin was observed to be effective in the treatment of LP without any side-effects. Enoxaparin may be an effective and simple alternative therapy for LP.Öğe The seroprevalence of varicella zoster antibodies in Behcet's and other skin diseases(Springer, 2003) Akdeniz, S; Harman, M; Atmaca, S; Akpolat, NThe purpose of this study was to investigate the association of the varicella zoster virus (VZV) IgG, and IgM antibodies with Behcet's and other skin diseases (group 1: recurrent aphthos stomatitis, fungal infections, psoriasis; group 2: vitiligo, lichen planus). Twenty eight patients with Behcet's disease ( BD), and 117 patients with dermatological disorders other than BD were evaluated for specific VZV IgG and IgM antibodies by using a third generation enzyme-linked immunosorbent assay (ELISA). The Mantel Heizshel chi(2) method was used to adjust the confounding of age and sex of the patients. The serological positivity for VZV IgG and IgM antibodies in BD was not statistically different from other skin diseases. When we considered the age of the patients, chi(2) = 2.64, CI (0.27-1.65), odds ratio (1, 1.25, 2.21) (p = 0.10) and when we considered the sex of the patients, chi(2) = 0.31, CI (0.81-1.28), odds ratio (1, 1.45, 1.41), (p = 0.57).Öğe Tinea capitis in Diyarbakir, Turkey(Blackwell Verlag Gmbh, 2005) Akpolat, NÖ; Akdeniz, S; Elci, S; Atmaca, S; Özekinci, TThe incidence and types of tinea capitis in 234 children aged 1-12 referred to our laboratory with a preliminary diagnosis of tinea capitis infection in the past 5 years were investigated. Tinea capitis was determined in 149 (63.7%) of these patients, of which agents grew in culture in 124 (83.2%). The most frequently isolated agents, in order of frequency, are as follows: Trichophyton violaceum (43.6%), Microsporum canis (37.9%), T. mentagrophytes (8.1%) and T. verrucosum (4.8%).
