    ABSTRACT: In this study the effect of hypoxia on thrombocytes was investigated in patients with a chronic obstructive pulmonary disease (COPD). 15 Hypoxic (group 1), 15 nonhypoxic (group 2) patients with COPD and 10 healthy persons (group 3) were included in the study. The differences in haemoglobin, hematocrit and PaCO2 values of group 1 and group 2 were insignificant, but there was a significant difference between group 3 and the other two groups. The differences in blood pH values in the above groups were insignificant, but the differences in FEV1, FVC and PaO2 values were significant. We found that thrombocyte aggregation increased significantly in group 1 and group 2. Also the platelet count decreased and mean platelet volume increased significantly in group 1. As a result, we think that in hypoxic patients with COPD, thrombocyte count decreases, volume and aggregation formation increases and oxygen plus antiaggregation therapy may have positive effects on the survival and life quality of these patients.

    ABSTRACT: From March 1992 to July 1992, 30 uremic patients (15 dialysed, 15 non-dialysed) and 15 non-uremic patients who had dyspeptic complaints were compared in terms of gastric and duodenal diseases. Gastritis and duodenitis graded as I, II and III were not found different in three groups (p > 0.05). Although the incidence of peptic ulcer disease is very high in both groups of uremic patients in comparison with the controls, there was no significant difference between two uremic groups (p > 0.05). Also the prevalence of gastritis determined histologically was not different in dialysed and non-dialysed uremic patients (p > 0.05). The incidence of the histologically proven gastritis was found higher in uremic patients than in non-uremic patients (p < 0.05). But, there were no significant differences among the three groups with regard to the rate of histologically proved duodenitis (p > 0.05). Gastrin levels, urea positivity, the incidence of gastritis and duodenitis and peptic ulcers did not differ in both uremic groups. However, these values were found significantly high in the uremic patients when compared to non-uremics. These findings showed serum gastrin levels, H.-pylori-infection, gastritis and duodenal disease in the uremic patients to be higher than those of the control group. Moreover, no effect of hemodialysis treatment on these results was observed.
