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.

Rauvolfia serpentina (L.) ex. Kurz is an important medicinal plant. Callus induction and regeneration was studied from stem explant of in-vitro grown plant of Rauvolfia serpentina(L.) Benth. ex Kurz (Apocynaceae) on Murashige Skoog (1962) medium supplemented with 1mg/l 2,4-Dichlorophenocy acetic acid (2,4-D) and 1mg/l Kinetin (Kn). Vigorous growth of callus occurs after 4 weeks of culture. Callus was sub-cultured on Murashige and Skoog (MS) medium supplemented with different concentration of 2, 4-D (0.5-3.0 mg/l) and 10% coconut milk. Regeneration of plantlets occurred on MS medium containing 3 mg/1 of 2, 4-D and 10% coconut milk. These plantlets were rooted on MS medium supplemented with 1 mg/l IAA .The regenerated plantlets were able to grow on soil after short period ofacclimatization. Key words: Explant; In-vitro culture; MS medium;  2, 4 Dichlorophenoxy acetic acid; Kinetin; Callus; Tissue culture; Coconut milk. Journal of Natural History Museum Vol. 24, 2009 Page: 82-88

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>
