    Kurzfassung: 〈 b 〉 〈 i 〉 Background: 〈 /i 〉 〈 /b 〉 Data on early biochemical and hematological responses to cobalamin therapy in vitamin B 〈 sub 〉 12 〈 /sub 〉 -deficient patients are scarce. Therefore, we investigated whether cobalamin injections would include prompt biochemical and hematological responses in vitamin B 〈 sub 〉 12 〈 /sub 〉 -deficient patients. 〈 b 〉 〈 i 〉 Subjects and Methods: 〈 /i 〉 〈 /b 〉 Seven female patients (mean age: 69.4 years, range: 61-78) with a mean serum cobalamin level of 104 ± 38 pmol/l mean ± SD and 7 male patients (mean age: 67.0 years, range: 53-78) with a mean serum cobalamin level of 84 ± 40 (±SD) participated in the study. They were administered 1 mg i.m. cyanocobalamin per week for 3 weeks. Blood samples were collected before and 1, 3, 7, 14 and 21 days after cobalamin injection. The concentrations of plasma aminothiols and serum methylmalonic acid (MMA) were measured with high-performance liquid chromatography and gas chromatography/mass spectrometry, respectively, and hematological parameters were determined with a hematological analyzer. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 Already 1 day after intramuscular Cobalamin injections, the concentrations of serum vitamin B 〈 sub 〉 12 〈 /sub 〉 and plasma total cysteine were significantly increased while the concentrations of serum folate, plasma total homocysteine and serum MMA were decreased. Mean cell volume was also significantly decreased first after 14 days of therapy. 〈 b 〉 〈 i 〉 Conclusion: 〈 /i 〉 〈 /b 〉 Intramuscular cobalamin administration causes swift and significant changes in plasma aminothiols, whereas the first change in hematological parameters was detected only after 14 days.

    Kurzfassung: 〈 b 〉 〈 i 〉 Objectives: 〈 /i 〉 〈 /b 〉 Cigarette smoke contains free radicals, which cause injury to endothelial cells and oxidize bioactive components in the blood. Neutrophils, a subpopulation of leukocytes, contain the enzyme myeloperoxidase that mediates production of hypochlorous acid during oxidative stress. In this study, we investigated whether smoker industrial workers had significantly higher neutrophil counts than nonsmoker industrial workers. 〈 b 〉 〈 i 〉 Design and Methods: 〈 /i 〉 〈 /b 〉 We collected blood samples from 183 apparently healthy male and 30 female industrial workers. We obtained blood cell counts, measured the concentration of plasma aminothiols and determined the concentration of serum and erythrocyte folate and serum vitamin B 〈 sub 〉 12 〈 /sub 〉 in the samples. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 Smoker industrial workers had significantly higher neutrophil, lymphocyte, monocyte, eosinophil and basophil counts than nonsmoker industrial workers (p 〈 0.0001, p 〈 0.0001, p 〈 0.0001, p 〈 0.0001 and p = 0.01, respectively). Mean corpuscular volume and mean corpuscular hemoglobin in smoker industrial workers were higher than in nonsmoker industrial workers (p = 0.001 and p = 0.03). 〈 b 〉 〈 i 〉 Conclusion: 〈 /i 〉 〈 /b 〉 Our study demonstrates that smoker industrial workers have higher neutrophil counts than nonsmoker industrial workers. Therefore, our observations suggest that smokers may become more easily prone to chronic inflammation than nonsmokers. About 84% of the study participants were male subjects; therefore, our findings may be more representative for men than women.
