A defect in erythropoietin (EPO) production has been advocated as being the main cause of anemia presented at time of diagnosis or during treatment by adults with solid tumors. On the basis of this defect, anemic cancer patients, both adults and children, have been treated with recombinant human EPO (rHuEPO). To further elucidate the pathophysiology of(More)
Osteoclast-like cell (OCL-like) differentiation is increased in long term cultures of bone marrow taken from paralyzed areas of paraplegic patients. Among the neuropeptides recently described in bone, calcitonin gene-related peptide (CGRP) has been shown in animal studies to inhibit bone resorption in vivo and OCL-like differentiation in vitro: its(More)
The metabolic burst (as measured by the spontaneous and stimulated nitroblue tetrazolium tests), the phagocytosis of heat inactivated bakers' yeast and of Staphylococcus aureus, the killing of Staph aureus, and the myeloperoxidase activity of polymorphonuclear neutrophils were studied in 11 patients receiving maintenance haemodialysis. Of these patients,(More)
Patients with a spinal cord section loose a significant amount of bone. After paraplegia, bone loss occurs below the lesional level and is the more dramatic in iliac bones and in the metaphyseal area of long bones. A peak of urinary calcium and hydroxyprolinuria is observed approximately 6 weeks after their lesion. To further understand the mechanisms(More)
Granulocyte colony-stimulating factor (G-CSF) has important direct and priming effects on different functions of normal mature polymorphonuclear leukocytes (PMNL). Previous study has shown an alteration in respiratory burst and bactericidal activities of PMNL harvested from children with cancer treated with chemotherapy. The present study evaluates the(More)
The human normal cerebellar cortex has been investigated using paraffin-embedded sections and a panel of antibodies against GFAP, NSE, NF 70 Kd and 200 Kd triplet proteins. The study has shown that: antiserum to GFAP labelled all and only astroglial elements; antibodies to NSE, NF 70 Kd and 200 Kd stained the perikaryon of all neurons, with two noticeable(More)
In a patient with systemic and nervous system IBS, the CSF cells were investigated by light and electron microscopy. An IBS of the B-cell type was identified in the CSF which proved, at both morphological levels, to be identical to that recorded in IBS in lymphoid tissue with regard to the malignant cell types and the absence of surface specialization. In(More)
In a sporadic case of primary maxillar Burkitt's lymphoma and secondary spinal epidural dissemination, the massive malignancy in the CSF was investigated by light and electron microscopy. At both levels the CSF tumor cells were strikingly similar, with the undifferentiated lymphoblasts that characterize Burkitt's lymphoma in tissue. However, the starry-sky(More)
