These myelomas are to be distinguished from the more commonly occurring multiple myeloma with simple marrow fibrosis and/or osteosclerosis. Furthermore, \"myelofibrotic\" myelomas are not identical to myelomas coexisting with true chronic idiopathic myelofibrosis, a condition which would appear to be extremely rare and should only be diagnosed if focal megakaryocytic hyperplasia with atypia can be unequivocally demonstrated.

The development of substances which enhance endothelial cell growth and accelerate their proliferation is therefore of great interest in such situations. In the present work naftazone was shown to accelerate human saphenous vein endothelial cell proliferation in vitro at concentrations which did not alter the hemostatic balance, resulting in a cell density at confluence 20% higher than in controls. This compound was able to partially substitute for serum requirements and further displayed additive effects in the presence of fibroblast growth factors. Thus naftazone, an original synthetic molecule distinct from growth factor peptides, is a promising candidate drug for the amelioration of vascular repair.</p>","PeriodicalId":19366,"journal":{"name":"Nouvelle revue francaise d'hematologie","volume":"37 3","pages":"187-92"},"PeriodicalIF":0.0,"publicationDate":"1995-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18573033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Allogeneic PBPCs have rarely been used as the sole measure to induce haematopoietic recovery after myeloablative therapy because of uncertainties regarding the durability of engraftment and the risk of acute and chronic graft-vs-host disease (GVHD). In addition, this technique requires the exposure of normal donors to granulocyte colony stimulating factor (G-CSF) in order to mobilise a sufficient number of PBPCs which can then be collected by leukapheresis. We report here our initial experience with allogeneic transplantation of PBPCs in order to demonstrate the feasibility and safety of harvesting sufficient numbers of PBPCs in healty donors. In addition, the early results presented in this communication show that allogeneic PBPCs can successfully be used to restore haematopoiesis in HLA-identical siblings of the donor without causing devastating graft-vs-host disease.</p>","PeriodicalId":19366,"journal":{"name":"Nouvelle revue francaise d'hematologie","volume":"37 6","pages":"377-9"},"PeriodicalIF":0.0,"publicationDate":"1995-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19873346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
