ABSTRACT Ribonuclease activity in thymus and lymph nodes is stimulated by cortisone; insulin increases ribonuclease activity only in the thymus. Growth hormone and theophylline do not cause changes in thymus and lymph nodes ribonuclease levels. Injections of cortisone combined with growth hormone or with theophylline increase the activity more than cortisone alone. Insulin does not enhance the action of cortisone on ribonuclease activity. A synergistic loss in weight of thymus and spleen was found after administration of cortisone in combination with either growth hormone or with theophylline.

The article reveals the measures undertaken by the Soviet state during the “thaw” in the fi eld of reproductive behaviour, the protection of motherhood and childhood. Compilations, manuals and magazines intended for women were the most important regulators of behaviour, determining acceptable norms and rules. Materials from sources of personal origin and oral history make it possible to clearly demonstrate the real feelings of women. The study of women’s everyday and daily life in the aspect related to pregnancy planning, bearing and raising children will allow us to compare the real situation and the course of implementation of tasks in the fi eld of maternal and child health. The demographic surge in the conditions of the economy reviving after the war, the lack of preschool institutions, as well as the low material wealth of most families, forced women to adapt to the situation. In the conditions of combining the roles of mother, wife and female worker, women entrusted themselves with almost overwork, which affected the health and well-being of the family. The procedure for legalising abortion gave women not only the right to decide the issue of motherhood themselves, but also made open the already necessary, but harmful to health, habitual way of birth control. Maternal care in diffi cult material and housing conditions became the concern of women and the older generation, who helped young women to combine the role of a working mother, which the country’s leadership confi dently assigned to women.

Menstruation was known as a natural process of hormonal control in the female reproductive organs. One of menstrual disorders was premenstrual syndrome or syndrome before menstruation or also known as tension before menstruation. Irregular menstrual cycles, decreased levels of progesterone, increased level of estrogen, stress, menarche age, and nutritional status were informed as factors that cause premenstrual syndrome. This study aimed to determine student’s knowledge to premenstrual syndrome. The methodology used was a cross sectional study. The population sample was a student of University Al Azhar Indonesia. The independent variables were selected, namely knowledge, age of menarche, menstrual cycle, exercise, nutrition, productivity, and body mass index (BMI). Based on the test bivariate and multivariate logistic regression found no significant relationship between knowledge with premenstrual syndrome in UAI student that knowledge with p value 0.169; OR 0.473; 95% CI 0.163 to 1.374. Respondents who had knowledge 0.473 times better than others in treatment of premenstrual syndrome.</strong><strong></strong></p><p><strong><em> </em></strong></p><p><strong><em>Keywords</em></strong><em>: Premenstrual Syndrome</em><em>, </em><em>knowlwdge, menstruation, menarche.</em><em></em></p>
