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.

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>

Plastic Trait

Many behaviors of insects are stimulated, modified, or modulated by hormones. The principal hormones involved are the same as the ones that control moulting, metamorphosis, and other aspects of development, principally ecdysone and juvenile hormone. In addition, a small handful of neurosecretory hormones are involved in the control of specific behaviors. Because behavior is a plastic trait, this chapter begins by outlining the biology and hormonal control of phenotypic plasticity in insects, and how the hormonal control of behavior fits in with other aspects of the control of phenotypic plasticity. The rest of the chapter is organized around the diversity of behaviors that are known to be controlled by or affected by hormones. These include eclosion and moulting behavior, the synthesis and release of pheromones, migration, parental care, dominance, reproductive behavior, and social behavior.
