The authors have investigated the cytokinetic behaviour of 23 cases of non-Hodgkin B cell lymphomas. In all cases diagnosis was established on the basis of histological, cytoimmunological and ...cytochemical data. The study, carried out with the aid of autoradiographic techniques, indicates that the various histological subclasses are characterized by a different metabolic and kinetic behaviour: the aggressiveness of the malignant lymphoma is closely related to the rate of growth of the lymphomatous cell populations, as assessed by the mitotic index and the labelling index with 3H-thymidine. The study of the synthesis and metabolism of RNA provides not only useful information on the energy requirements necessary for the neoplastic growth, but, when employed in association with immunohistochemical techniques for the detection of intracytoplasmic Ig synthesis, it defines more accurately the functional characteristics and the differentiation potentialities of the neoplastic populations in different cases.

Euromeccanica, part of the Smaltochimica Group, has developed a project, called Iride in Design, for the management of colour in ceramic and the rapid prototyping of new ceramic tile designs. This ...technology minimises the experimentation and tests required to achieve the final prototype, with subsequent savings on project planning and production start-up time. IRIDE is a colorimetric system (spectrophotometer-software) which can be used to reformulate, using only 15 to 20 basic ceramic pigments, any colour used for the preparation of ceramic inks. The required amounts can be produced quickly and easily by combining IRIDE with an automatic dosing system for ink preparation (Tintometer). Benefits include time and cost savings, reduced waste, and reduced consumption of pigments. Current standard procedures for creating a new graphic design are outlined, and the advantages of the Iride in Design prototyping project are noted.
The incidence of haematological abnormalities has been evaluated in 1170 patients affected by acute viral hepatitis. Of these patients, 665 were HBsAg+, 427 HBsAg-, 31 with IgM anti-HAV, 26 non A and ...non B hepatitis. 21 patients were not classified due to lack of data relating to markers for HAV or HBV. Anemia, leucopenia, thrombocytopenia and pancytopenia were found with some frequency at the haemochromocytometric examination. It is emphasized that these haematological abnormalities are often of minor relevance whereas the rarer and more serious complications such as persistent bone marrow hypoplasia or pure aplastic anemia can present difficult clinical problems regarding prognosis and therapy: in 4 cases of bone marrow hypoplasia a recovery was obtained in 1 case only, whereas the remaining cases had a fatal outcome after a period varying from 20 days to 15 months from the appearance of pancytopenia. We suggest the advisability of a closer study of the haematological and immunological aspects in patients with viral hepatitis in order to discover those elements which are useful towards a better understanding of the etiopathogenesis of the haematological abnormalities studied above. Such a detailed study would also enable further improvement in existing therapeutic measures.

In this report we review the prospects for Higgs physics at LEP2. The
theoretical aspects and the phenomenology of Higgs particles are discussed
within the Standard Model (SM) and the Minimal ...Supersymmetric Standard Model
(MSSM). The experimental search techniques are described and the discovery
limits for Higgs bosons in the LEP2 energy range are summarized. In addition,
opportunities of detecting Higgs particles in non-minimal extensions of the SM
and the MSSM are investigated.
