Cigarette smoke and bleomycin-induced pulmonary oxidative stress in rats.

Bleomycin causes pulmonary fibrosis by increasing free oxygen radicals. Cigarette smoke is a strong oxidant which adversely affects pulmonary tissue. We evaluated the effects of cigarette smoke administered with intratracheal bleomycin on pulmonary tissue.

[Diagnostic efficiency of serum lipid-bound sialic acid level in malignant pleural effusions].

In this study, pleural fluid and serum lipid-bound sialic acid (LBSA) levels of 68 cases with pleural effusion hospitalised at the department of Chest Diseases in the Medical School of Selçuk University, and serum LBSA levels of 30 healthy individuals as control group were studied. Pleural effusions of 32 cases were due to malignancy of which considerably lung cancer. In the other 36 cases the causes were nonmalignant in origin.

[Diagnostic efficiency of pseudocholinesterase level in discrimination of transudates-exudates].

In this study, 80 cases with pleural effusion hospitalized at the departments of Chest Diseases and Internal Medicine in the Medical School of Selcuk University, and 30 healthy people as control group were studied. Regarding to the diagnosis, pleural fluids were classified into two groups as follows; transudates and exudates. Difference between the mean pleural pseudocholinesterase levels of transudates and exudates was statistically significant (p< 0.
