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)
It was demonstrated previously that mice undergoing an inflammatory reaction induced by subcutaneous (SC) implantation of copper rods, produce humoral factors that initially enhance, but subsequently inhibit, diffusion chamber (DC) granulopoiesis. This provided evidence that granulopoiesis is under the control of both humoral stimulators and inhibitors. In(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 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)
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.
