Figure 2. Analyses of the peripheral blood in patients with glioma WHO grades III (a) and IV (b). The pre- and postoperative C-reactive protein(CRP) values were measured in serum by turbidimetry and were categorized as low (≤5 mg/l) or high (>5 mg/l). In 30 cases, the sera samples from patients were tested for the presence of specific antibodies against four viruses. Specific antibodies against herpes simplex virus -1, -2 (HSV-1, -2 and human enteroviruses (hEV) were detected by complement fixation test (CFT).
