and destruction of the lung parenchyma, which leads to expiratory airflow limitation. 1-3 There are several reports indicating that endogenous cytokines and eicosanoids stimulate recruitment and activation of neutrophils and promote inflammation. Studies have revealed increased levels of proinflammatory mediators such as interleukin 8 (IL-8), 8-isoprostane, and INTRODUCTION Chronic obstructive pulmonary disease (COPD) is characterized by irreversible airflow limitation, which is usually progressive and is caused by abnormal inflammatory response of the lungs to noxious particles or gases. 1-3 The pathological hallmark of COPD includes neutrophilic inflammation of the peripheral airways

PurposeL1CAM is a cell adhesion molecule suspected to play an important role in carcinogenesis. The objective of the study was to evaluate the level of soluble L1CAM in the sera of patients with endometrial and ovarian carcinomas and verify the feasibility of the sL1CAM as a marker of these carcinomas.Methods35 endometrial and 18 ovarian cancer patients were enrolled in the study. 43 patients with benign gynecological conditions constituted a control group. The sL1CAM serum level was measured with ELISA test in each patient and it was referred to the data from the surgical staging of the cancers.ResultsThe sL1CAM serum level was significantly lower in patients with endometrial cancer than in healthy women and slightly lower in the ovarian cancer group than in the control group. In the endometrial cancer group there was no correlation between sL1CAM concentration and cancer histopathology, stage or grade. sL1CAM concentration positively correlated with ovarian cancer stage and (not significantly) with grade.ConclusionsDespite the increasing data about the possible role of L1CAM as a strong prognostic factor of poor outcome in many cancers, we did not find evidence supporting the use of sL1CAM as a marker of endometrial or ovarian cancers.

Mean (± SD) blood levels of 8-isoprostane in patients with type 1 diabetes mellitus without complications and those with type 1 diabetes with advanced complications were significantly higher compared to the control group (178.17 [135.73] vs. 183.34 [200.41] vs. 47.13 [25.20] pg/ml; p < 0.05). The mean (± SD) concentration of 8-isoprostane in EBC was lower in diabetic patients with type 1 diabetes with advanced complications than in patients with type 1 diabetes without advanced complications and in the control group (8.32 [4.60] vs. 19.13 [22.35] vs. 28.17 [35.11] pg/ml; p < 0.05). Measurement of 8-isoprostanes in the EBC in patients with type 1 diabetes does not appear to be a good diagnostic tool for monitoring the activity of oxidative stress in these patients.
