Abstract
Increased DNA damage has been suggested to contribute to the pathogenesis of chronic inflammatory diseases, but controlled studies are lacking in ankylosing spondylitis (AS). Therefore, we assessed oxidative stress, oxidative DNA damage, chromosomal DNA damage, cell proliferation and cell death in the peripheral blood lymphocytes of patients with AS as well as the possible role of DNA damage in the development of the disease. In total, 25 newly diagnosed AS patients who had not received anti-inflammatory agents and 25 healthy controls were recruited. Oxidative DNA damage was assessed by plasma 8-hydroxy-2'-deoxyguanosine (8-OHdG) levels, and chromosomal DNA damage was assessed by the cytokinesis-block micronucleus cytome (CBMN-cyt) method. Compared to controls, the micronucleus (MN) frequencies, nucleoplasmic bridge (NPB) frequencies, nuclear bud (NBUD) frequencies, apoptotic cell frequencies, necrotic cell frequencies and plasma 8-OHdG levels were significantly higher in patients with AS (p < 0.001, p < 0.05, p < 0.01, p < 0.001, p < 0.001, and p < 0.001, respectively), and the metaphase cell numbers, binucleated (BN) cell frequencies and nuclear division index (NDI) values were significantly lower in patients with AS (p < 0.01, p < 0.001 and p < 0.001, respectively). Thus, the present findings suggested that oxidative stress, oxidative DNA damage, and chromosomal DNA damage may be involved in the pathogenesis of AS similar to other chronic inflammatory diseases. In addition, the increased plasma 8-OHdG levels, MN frequencies, NPB frequencies and NBUD frequencies in AS patients may reflect an increased cancer risk.

Abstract
In this study, the immunocytogenetic effects of Decapeptyl ® (Triptorelin Pamoate) were assessed in the peripheral blood lymphocytes of females undergoing in vitro fertilization (IVF) treatment. Blood samples were taken from 34 females (23 treated and 11 controls), cultured and examined for sister chromatid exchanges (SCE) and cell replication index (CRI). The SCE frequency increased around ovulation time in the controls, and around the time of human chorionic gonadotropin administration in the IVF group. However, the SCE rate was significantly higher in the latter group. Furthermore, the white blood cells (WBC) count was significantly higher on the day of ovum pick up compared to the day preceding luteinizing hormone (LH) and follicle stimulating hormone (FSH) treatment. Similar observations were recorded with respect to phagocytic activity tested by nitroblue tetrazolium (NBT) assay. The nitric oxide production abilities of macrophages were not significantly changed in the LH, FSH-treated group relative to its control. Finally, the 50% complement hemolytic activity (CH50) assay results indicated that Decapeptyl lacks a significant potential to affect the complement system.

Abstract
Fifty years have elapsed since the discovery of the number of human chromosomes in 1956. Newer techniques have been developed since then, ranging from the initial conventional banding techniques to the currently used molecular array comparative genomic hybridisation. With a combination of these conventional and molecular techniques, cytogenetics has become an indispensable tool for the diagnosis of various genetic disorders, paving the way for possible treatment and management. This paper traces the history and evolution of cytogenetics leading up to the current state of technology.

Abstract
OBJECTIVE Hydatid disease occurs throughout the world and is treated with both surgery and medical administration of albendazole. Some adverse effects of albendazole are known. However, its genotoxic effect on humans has not been reported yet. In this study, we aimed to investigate the genotoxic effect of albendazole on human lymphocytes in vivo. METHODS The study involved 14 children (eight males and six females) who had undergone operations for hepatic hydatid disease. The ages of the patients ranged from 6 to 13 years. Genotoxicity of albendazole was evaluated as the frequency of sister chromatid exchange (SCE) and micronucleated cells in the patient's lymphocytes. Prior to and after albendazole treatment, blood samples were obtained from these patients for SCE and micronucleus (MN) studies. SCE and MN frequencies of the patients were measured separately before and after albendazole treatment. RESULTS All patient SCE values increased significantly after albendazole administration (p<0.001). Similarly, MN frequencies in all the patients increased significantly following albendazole treatment (p<0.001). CONCLUSION This study revealed that both SCE and MN frequencies are higher after albendazole treatment. The results suggest that albendazole may be genotoxic to human lymphocytes in vivo.

Abstract
The combination of genetic susceptibility and environmental factors can induce allergic sensitization and subsequent local inflammation, resulting in atopic dermatitis (AD). Sister chromatid exchange (SCE) is a sensitive method that may reflect an instability in DNA or a deficiency in DNA repair. The aim of the present study was to investigate whether patients with AD have defects in DNA repair and whether SCE frequency can be used as a genetic marker in the pathogenesis of AD. Between September 2004 and July 2005, SCE was analyzed in the peripheral blood lymphocyte chromosomes of 32 patients with AD and 28 control subjects at the Dermatology Unit of Erzurum State Hospital. This study found that the SCE frequency was significantly increased in patients with AD (P < 0.00001). The prevalence of SCE was not correlated with patient age, sex, disease duration or AD disease severity. Our results indicate that increased chromosome instability may play an important role in the etiology of AD.

Abstract
Behcet's disease is a chronic multisystemic disease of unknown pathogenesis characterized by four major symptoms: oral aphthous ulcers, skin lesions, ocular symptoms and genital ulcerations. The disease is spread throughout the world, but it is most frequent in Turkey, Japan, Korea and China. Although HLA-Bw51 has been found to predominate in Behcet's cases, the genetic etiology has not yet been clarified. In this study, we investigated the chromosomal abnormalities and sister chromatid exchange rates in patients with Behcet's diseases. Thirty-eight patients with Behcet's disease (diagnosed for the first time) and 30 healthy subjects (as controls) were included in this study. Although numerical and structural chromosomal abnormalities were not detected in our patients, we found an increased rate of sister chromatid exchange in patients over the control groups (P < 0.01). On the basis of these results, we discuss the genetic etiology of Behcet's disease.

Abstract
Invasive cardiology laboratory workers are occupationally exposed to chronic ionizing radiation. It is known that ionizing radiation has a damaging effect on chromosomes. In present study. we investigated the frequency of sister chromatid exchange (SCE) and chromosomal aberrations in 11 invasive cardiology laboratory workers and 11 healthy controls. After a vacation period, we took blood samples for chromosome analysis in months 0, 4, 8 and 12 (last two month period was the nonradiation time). The SCE frequencies did not change significantly after exposure to ionizing radiation in any worker. Our study has revealed that non-specific structural chromosome aberrations such as gaps, isogaps, acentric chromosomes, chromatids and chromosome breakage could be in the 4th and 8th months after ionizing radiation exposure in the metaphase plaques. All abnormal chromosomal effects had disappeared by the end of the two month non-exposure period in each worker. In conclusion, the results suggest that SCE frequencies are not significantly affected in invasive cardiology laboratory workers who are exposed occupationally to ionizing radiation, although some degree of reversible chromosomal aberrations did appear.

Abstract
Behçet's disease (BD) (OMIM 109650) is an immunogenetically based multisystem disease, characterized by iridocyclitis, arthritis, orogenital ulcerations and pustular skin lesions. Viral and autoimmune etiologies have been suggested and HLA-B5 has been found to predominate in BD. The disease is most seen in Turkey and Japan. Although familial cases have been reported, the mode of inheritance is not clear. To determine the genetic instability in BD, sister chromatid exchange (SCE) analysis has been performed on peripheral lymphocytes in 23 patients and 20 healthy controls. We found significantly higher SCE rates in the patient group (p < 0.0001). Our results may indicate that genetic impairment and genetic instability may play an important part in the etiology of BD.

Abstract
To determine the genotoxic risk associated with diagnostic exposure to low doses of iodine 131 (131I), sister chromatid exchange (SCE) analysis was performed in lymphocytes of 18 non-smoking women who received 370 kBq (10 microCi) intravenous 131I sodium iodide as an adjuvant for scintigraphy for diagnosing thyroid nodularity. SCE frequencies were measured before and after 131I administration. SCE results in the pre-treated phase were regarded as control. Although SCE values 24 h after 131I administration did not show a significant increment (p > 0.05), there was a significant increase 72 h after treatment (p < 0.05). These results indicate that genetic damage might be induced by low dose of 131I.
