Treatment with sulfinpyrazone of essential mixed cryoglobulinemia.

Platelet production time (PPT), circulating platelet aggregates (CPA ratio) and plasma beta-thromboglobulin (beta TG) were determined in patients with essential mixed cryoglobulinemia (EMC) before and after two months' treatment with sulfinpyrazone. Sulfinpyrazone determined a clinical improvement in 8 of the 16 patients. Basal PPT and CPA ratio were reduced compared with normal values but not significantly; after sulfinpyrazone treatment both PPT and CPA ratio increased to normal levels. High plasma beta TG levels were found before and after treatment. These data suggest that in some cases of EMC there is a picture of in vivo platelet activation, but with the small number of patients it was not possible to evaluate a possible correlation between platelet hyperactivity and the clinical picture.

[Interferon in the treatment of multiple myeloma].

The effect of recombinant interferon-alpha-2C monotherapy was compared with the efficacy of VMCP-polychemotherapy in 42 patients with multiple myeloma in a prospective randomized multicenter trial. IFN-treatment induced remissions (R) in 2 (14%) and partial remissions (PR) in 4 (29%) out of 14 evaluable patients. 7 patients remained stable. Polychemotherapy induced R in 11 (57%) and PR in 6 (32%) of 19 evaluable patients. 2 (11%) patients remained stable. IFN was preferentially active in patients with low tumor burden and patients with IgA paraprotein. The proportion of responders (R + PR) was significantly lower in the IFN-arm (43%) compared to the polychemotherapy group (89%; p less than 0,001).

[Pharmacological and clinical aspects of S-adenosylmethionine (SAMe) in primary degenerative arthropathy (osteoarthrosis)].

After some preliminary remarks of a biochemical and pharmacological nature, the authors have started a clinical study to test the antiinflammatory activity of the S-adenosyl-methionine (SAMe). An open trial, carried out on 90 patients with severe degenerative arthropathies has shown that 30 mg SAMe intravenously twice a day for 14 days have a marked anti-inflammatory effect a rather term and no side-effects. In a "double-crossover" investigation, SAMe was next compared to indomethacin by i.m. administrations to 15 arthropathic patients. The therapeutic responses of the two drugs proved exactly alike, whereas the side-effects following indomethacin administration were not present after SAMe. In 9 patients affected with rheumatoid arthritis administrations of SAMe have proved less effective, although some clinical parameters showed improvements.

Human leukemic intermediate DNA components.

The DNA extracted from human leukemic leucocytes has been fractionated on a methylated albumin kieselguhr (MAK) column. The different fractions obtained have been reannealed to a Cot value of 20 mol times sec/1 to study the distribution of the intermediate DNA on the MAK column. Intermediate DNA contains two components, one (CsCl density after reannealing, 1.703 g/ml) obtained by reannealing high molecular weight DNA, the other (CsCl density after reannealing, 1.707 g/ml) obtained only by reannealing sonicated low molecular weight DNA. High molecular weight intermediate DNA (1.703 component) is eluted early from the MAK column in the fractions corresponding to the main DNA peak, while low molecular weight intermediate DNA (1.707 component) is more widespread on the MAK column, but appears to be enriched in the fractions eluted later. The possibility is discussed that the latter component is interspersed in that part of the genome which is apparently more homogeneous in density in an analytical CsCl gradient, and is absent on the skewed, more heterogeneous, heavy side of the main DNA in CsCl.

Hybridization of mouse leukemia virus c-DNA to mouse repeated DNA sequences.

Experiments of hybridization between mouse leukemia virus synthetic 3H-DNA probe and mouse main band and satellite DNAs indicate that there is not a higher concentration of viral sequences in the satellite DNA. On the contrary, viral sequences appear to be enriched in the fast renaturing intermediate main band DNA.
