[Pancreatic beta cells and cytokines].

Over the past decade the study of Interleukins and Interferons has advanced from functional descriptions to detailed structural understanding. The ability of these growth factors to act, directly or through immune mechanisms on the pancreatic beta-cell and to affect in vitro and in vivo both its morphology and physiology, indicate that they may play a role in the pathogenesis and prevention of insulin-dependent diabetes mellitus. Also, the relation between these cytokines-constitutive or upon stimulation maybe useful to predict the development of diabetes mellitus.

Results of a randomized study of previously-untreated intermediate and high grade lymphoma using CHOP versus CNOP.

A randomized multicenter phase III study was conducted to compare the efficacy and toxicity of CHOP and CNOP in intermediate and high-grade non-Hodgkin's lymphoma. CHOP consisted of cyclophosphamide 750 mg/m2, vincristine 1.4 mg/m2, doxorubicin 50 mg/m2 on day 1 and prednisone 50 mg/m2 on days 1 to 5.
