Serum copper and zinc concentrations and copper/zinc ratios have been shown to be increased in several types of human malignancies, including human brain tumors. In this study, copper and zinc levels and copper/zinc ratios were determined by atomic absorption analysis in tissue and serum from 29 primary and metastatic brain tumor patients. Metastatic(More)
Total excision is the treatment of choice in preventing the relapse of craniopharyngioma, but for tumors involving an extensive area, it is often associated with increased risks of complications. The efficacy of postoperative radiotherapy has not yet been established. The authors have performed minimal tumor excision followed by intensive injection of(More)
UNLABELLED A rebound phenomenon after infusion of hypertonic solution of mannitol and glycerol on raised intracranial pressure was studied by epidural pressure recordings for 65 patients. The mean age of the patients was 50 years with a range of 29 to 73 years. The diagnoses of above patients were as follows; 29 were cerebral aneurysms, 19 were brain(More)
The relationships between protein extravasation, morphological changes in neurons, and reactive changes in axons were evaluated in rats subjected to right lateral fluid-percussion injury to the brain (4.8-5.6 atm, 20 ms). Serial sections of the brain were immunostained with antibodies to rat immunoglobulin G (IgG) and 68-kDa neurofilament at 1 h to 2 weeks(More)
Serial computed tomography (CT) scanning was performed on 138 patients suffering from severe head injuries (i.e., with scores of 8 or less on Glasgow Coma Scale). Standard practice called for scans to be done upon admission (within hours of the injury) and after 1, 3, and 7 days and 1 month. Subsequent CT scans depended on the patient's condition. Clinical(More)
The relationship between the levels of serum acute phase reactant proteins (alpha 1-acid glycoprotein, alpha 1-antitrypsin, haptoglobin) was investigated in patients with glioblastoma multiforme in relation to their prognosis. Alpha 1-acid glycoprotein was higher in the patients who died within one year after admission than in those with a longer survival(More)
The pyrithiamine-treated rats produced by our method histopathologically exhibited the edematous lesion not only around the third ventricle and at the tegmentum of pons, as expected, but also in the cerebral cortex. These animals were, therefore, used in a biochemical study of the cerebral cortex, in particular, glucose metabolism. The results indicate an(More)
Few morphological studies have been reported on fluid-percussion experimental models using mechanically induced severe brain injury have been reported. This study was initiated to evaluate microscopic and immunohistochemical findings in severe brain injury models using rats. The experimental rats and the methods used were the same as described for a(More)
Trace element such as Cu and Zn have important chemical and biological properties. Recently, tissue Cu and Zn concentrations have been correlated with prognosis in selected malignancies. In addition, depletion of trace metals has suppressive effects on tumor growth in experimental rat models. We measured tissue levels of Cu and Zn and investigated the(More)
