Anthracycline antibiotics non-covalently incorporated into the block copolymer micelles: in vivo evaluation of anti-cancer activity.

The chemosensitising effects of poly(ethylene oxide)-poly(propylene oxide)-poly-(ethylene oxide) (PEO-PPO-PEO) block copolymers (Pluronic) in multidrug-resistant cancer cells has been described recently (Alakhov VY, Moskaleva EY, Batrakova EV, Kabanov AV 1996, Biocon. Chem., 7, 209).

[The extratumor mechanisms of osteolysis in multiple myeloma and the means for their correction].

In 70 patients with stage III multiple myeloma (MM) the authors studied spontaneous and lipopolysaccharide-induced production of interleukin-1 (IL-1) and interleukin-6 (IL-6) by blood and bone marrow mononuclear cells, concentration of parathyroid hormone and vitamin D3 in the serum. Bone marrow density was measured at photon absorption (Gambro), in patients treated with osteoprotectors bonefos and oxidevit before and after therapy (3.5-6 month course).

[Production of interleukin-1 and interleukin-6 in a culture of mononuclear cells of peripheral blood and bone marrow in multiple myeloma].

Constitutive and lipopolysaccharide (LPS)--induced production of interleukin (IL)-1 and IL-6 have been investigated in peripheral blood (PB) and bone marrow (BM) of patients with multiple myeloma (MM) and PB of health donors. The level of these cytokines has been higher in MM in comparison with norm. Monocytes of PB of patients with MM have been more stimulated by LPS than those of health people.

[The production and characteristics of an interleukin-6-dependent hybridoma].

The interleukin-6-(IL-6)-alpha dependent B-cell heterohybridomas were obtained by the fusion of X65.Ag8.653 cells with spleen cells from August rats immunized with lipopolysaccharide E.
