Background. N‐acetyl cystein, a mucolytic agent, might make Helicobacter pylori antigens shed more easily to stool, and might therefore contribute to the diagnostic accuracy of the Helicobacter pylori stool antigen test. The aim of this study is to investigate if N‐acetyl cystein contributes to the diagnostic accuracy of the Helicobacter pylori stool antigen test by increasing the sensitivity and specificity of the test.

The primary source of ammonia is the gut. Ammonia can also be generated by the urease activity of Helicobacter pylori in the gastric mucosa. The aim of this study was to investigate the effect of H. pylori eradication on blood and gastric juice ammonia levels and on visual evoked potential (VEP) recordings in cirrhotic patients.

OBJECTIVE To define the light microscopic cytologic changes due to chemotherapy (CT) and/or radiotherapy (RT); to evaluate the differentiation of those changes according to treatment; to find out whether a relation exists between treatment type and its duration and the cytologic findings; and to determine the role of sputum cytology in evaluating efficacy of treatment and follow-up in patients with inoperable lung cancer of various histology. STUDY DESIGN A total of 1,605 periodic sputum samples from 80 cases of lung cancer obtained during treatment and follow-up were prospectively examined cytologically. The relationship of treatment type and duration to qualitative and semiquantitative data and the definability of the response to treatment as well as the relationship of progression-free survival (PFS) and total survival (TS) rates with cytologic data were evaluated. RESULTS The majority of therapy-induced cellular changes were in the nucleus and were directly related to the duration of treatment. An increase in minimally affected tumor cells, tumor cells that lost their pathologic features and necrotic cell debris were good indicators of therapeutic efficacy. Cytologic changes did not reflect PFS and TS rates. CONCLUSION Although light microscopic cytologic changes cannot be attributed objectively to either RT or CT, therapeutic efficacy is shown in follow-up sputum cytology, which can be used in monitoring and planning additional therapy or other therapeutic options in lung cancer patients.
