    Serum adenosine deaminase, catalase and carbonic anhydrase activities in patients with bladder cancer
    (2012) Pirinççi N.; Geçit I.; Güneş M.; Yüksel M.B.; Kaba M.; Tanik S.; Demir H.; Aslan M.
    OBJECTIVES: The relationship between adenosine deaminase and various cancers has been investigated in several studies. However, serum adenosine deaminase activity and carbonic anhydrase and catalase activities in patients with bladder cancer have not previously been reported. Therefore, the aim of this study was to measure serum adenosine deaminase, carbonic anhydrase and catalase activities in patients with bladder cancer. MATERIALS AND METHODS: Forty patients with bladder cancer and 30 healthy controls were enrolled in the study. Serum adenosine deaminase, carbonic anhydrase and catalase activities were measured spectrophotometrically. RESULTS: Serum adenosine deaminase, carbonic anhydrase and catalase activities were significantly higher in patients with bladder cancer than controls (all significant, p<0.001). CONCLUSIONS: These markers might be a potentially important finding as an additional diagnostic biochemical tool for bladder cancer. © 2012 CLINICS.

    Levels of serum trace elements in renal cell carcinoma case
    (Asian Pacific Organization for Cancer Prevention, 2013) Pirinççi N.; Geçit I.; Güneş M.; Kaba M.; Tanik S.; Yüksel M.B.; Arslan H.; Demir H.
    Trace elements which are essential components of biological structures may also be toxic when present at levels above the amounts required for biological function. In our study, traceelement levels were measured with furnace atomic absorption spectrophotometry in 33 newly diagnosed renal cell carcinoma cases (preoperative) and 32 healthy controls. When compared with the control group, it was found that the levels of cadmium (Cd), lead (Pb) were higher and the levels of zinc (Zn), iron (Fe) and manganese (Mn) were lower in the patient group.These changesmay be important in the formation of renal cell carcinoma, a question which should be exploredwith postoperative comparative studies.
