    Effects of erdosteine on hemostasis: An experimental study
    (Sage Publications Ltd, 2012) Tutanc, M.; Arica, V.; Motor, S.; Basarslan, F.; Erden, E. S.; Ozturk, O. H.; Zararsiz, I.
    Aim: In this study, the effects of erdosteine (ED) on the platelet function and coagulation were investigated in adult rats. Materials and Method: Twenty-eight male Wistar albino rats were divided into four groups. The control rats in group I (n = 7) were given only 0.5 cc of normal saline daily through oral gavage. Group II (n = 7) rats were administered 3 mg/kg ED through oral gavage for 3 days; while group III (n = 7) rats were given 10 mg/kg ED through oral gavage for 3 days; and group IV (n = 7) rats were administered 30 mg/kg ED through oral gavage for 3 days. Prothrombin time (PT), activated prothromboplastin time (aPTT), international normalized ratio (INR), coagulation factors and complete blood counts were measured from the blood drawn. Results: There were a lot of differences between ED groups and control group, and among ED groups. The found differences were level of PT, aPTT, INR, coagulation factors, and number of platelets. Discussion: We consider that ED which is used as a mucolytic agent in child clinics may affect hemostasis and coagulation in a dose-dependent manner. ED should be used carefully by the patients with coagulation disorders, since there is no information available in the package insert and literature screening regarding the effect of ED.

    Investigation of Bisphenol A as an endocrine disruptor, total thiol, malondialdehyde, and C-reactive protein levels in chronic obstructive pulmonary disease
    (Verduci Publisher, 2014) Erden, E. S.; Motor, S.; Ustun, I.; Demirkose, M.; Yuksel, R.; Okur, R.; Oktar, S.
    OBJECTIVE: Chronic obstructive pulmonary disease (COPD) is a common health problem and it is associated with oxidant/antioxidant imbalance and systemic inflammation. Bisphenol A (BPA) is an endocrine disruptor agent, exerting a wide variety of metabolic effects. Also, BPA is related with oxidative stress, decreased antioxidant enzymes, and inflammation. The aim of this study is to investigate the relationships between COPD and serum BPA, Creactive protein (CRP), malondialdehyde (MDA), and total thiol levels. PATIENTS AND METHODS: This study was enrolled at 83 subjects that they were divided into two groups: control (n = 33), COPD (n = 50). The serum BPA, CRP, MDA, and total thiol levels were analyzed. RESULTS: The CRP and BPA levels were significantly higher in the COPD patients than control subjects. The total thiol levels were significantly lower in COPD cases than the controls. There is no different between groups for MDA. Also, there had a linear relationship between BPA and CRP in correlation analysis. CONCLUSIONS: COPD is associated with high serum BPA, CRP and low total thiol levels in comparison with healthy individuals. It is suggested that BPA might have a role in the etiopathogenesis of COPD.

    Nebulized salbutamol for asthma: Effects on serum potassium and phosphate levels at the 60 min
    (Elsevier Doyma Sl, 2013) Sahan, M.; Yilmaz, M.; Gokel, Y.; Erden, E. S.; Karakus, A.
    Objective: We conducted this prospective study to expand available information in relation to serum phosphate levels in treatment of acute asthma. A beta-adrenergic agonist, salbutamol, was used for this purpose. Material and methods: Twenty-six patients who met the inclusion criteria as; age over 16 years, asthma history, and an acute exacerbation were included. Serum blood urea nitrogen, creatinine, glucose were within normal limits in all the patients. None of the patients were on chronic theophylline therapy. Baseline serum phosphate and potassium levels were measured. Nebulized salbutamol (2.5 mg) was used three times at every hour. After 60 min, serum phosphate and potassium levels were measured. Results: Serum phosphate levels decreased from 3.7 +/- 0.9 mg/dL (baseline) to 3.6 +/- 0.9 mg/dL at 60 min. This decrease was not statistically significant (p=0.373). Serum potassium levels decreased significantly (p < 0.001) from 4.6 +/- 0.7 mmol/L (baseline) to 4.3 +/- 0.7 mmol/L (60 min). Conclusion: Administration of nebulized salbutamol during the emergency treatment of acute exacerbation of asthma is not associated with a statistical decrease in serum phosphate. There was significant hypokalemia. This study indicates that a further study is needed to elucidate the clinical significance of nebulized salbutamol on serum phosphate.
