[Generational differences in perception of menstruation and attitude to menstruation].

Based upon a model of individual differences in menstrual experiences the study concerns the question of similarities and difference in menstrual experience and attitudes between mothers and their daughters. 60 mothers (mean age 46.5 years) and 60 daughters (mean age 19.9 years) were investigated using a comprehensive questionnaire which included standardized measures such as the German version of the Menstrual Attitude Questionnaire. Comparisons of both groups revealed significant differences in relation to sex education, preparation for menstruation, and the experience of menarche, which were described more positive by the generation of the daughters. Differences in menstrual cycle effects on wellbeing and behavior were less clear. Behavioral changes and restrictions both demonstrated the significance of the mothers influence on their daughters. Inspite of more positive conditions for a "menstruation related socialization" mothers and daughters showed only slight differences in their menstrual attitudes. This result could confirm the importance and persistence of cultural norms.

Effect of interleukin-2 on the ex vivo growth of human myeloma cells.

Short-term cultures containing bone marrow mononuclear cells from multiple myeloma patients secrete monoclonal immunoglobulin- and beta 2-microglobulin into the supernatant, which can be measured quantitatively in an enzyme-linked immunosorbant assay. In this system, the addition of interleukin-2 was shown to induce tumor cell regression in the cultures from 10 out of 14 multiple myeloma patients in a dose-dependent manner. Marker analyses of culture cell populations indicate that OKT3 antibody or interleukin-2 did not directly act on the malignant clone but augmented autologous T lymphocytes, which were responsible for the regression of tumor cells in the cultures.
