A quantitative determination of the relative amount of histones in polyacrylamide gel by silver stain.

On the basis of scanning densitometry of the stained gel, the conditions for the quantitative determination of individual histones by silver was examined and compared with the dye-staining method, in terms of higher sensitivity and faithful quantitation. Fixation with formaldehyde, coupled with simultaneous prestaining with Coomassie brilliant blue (CBB), was found to be most suitable. Prior fixation in acidic alcohol alone failed to stain the histones accurately, but this failure could be partly alleviated by prestaining with CBB. Although the sensitivity for detecting histones by silver staining is lower than that for neutral proteins by about 10-fold, it is at least 10-fold higher than the CBB stain.

[Clinical effects of human lymphoblastoid interferon in patients with hematologic neoplasms].

Sixteen patients with hematologic neoplasms were treated with Human Lymphoblastoid Interferon (HL-BI) derived from Namalwa cell line. They were 6 multiple myeloma, 8 acute leukemia and 2 malignant lymphoma patients. All patients were previously treated with anticancer agents except one case with multiple myeloma. HLBI, 3.0 X 10(6) IU/day, was daily administered by intramuscular injection at least for 4 weeks. Three of 6 multiple myeloma responded to HLBI with a decrease of more than 25% in serum myeloma protein level. A case with pleural effusion due to massive infiltration of myeloma cells treated with intrathoratic administration of HLBI, in whom complete disappearance of pleural effusion was recognized. On the other hand, no patients with acute leukemia and malignant lymphoma responded except one case with acute lymphocytic leukemia, in which bone marrow lymphoblasts decreased transiently. Fever episodes, 13 of 16 cases, were more frequently seen but were manageable. Transient leukocytopenia and thrombocytopenia were also observed in 4 and 7 of 8 cases, respectively. No anaphylactoid reaction was seen. Thus, HLBI was expected useful in the clinical management of multiple myeloma.
