1. Silva, José Carlos Gama da, 1943-. Avaliação clinico-laboratorial da administração de esteroides anticoncepcionais em aneis vaginais da silastic.

Degree: 1989, Universidade Estadual de Campinas

Abstract: Patients using three forms of hormonal contracept ion were studied during one ~ear. The methods studied were two models of vaginal rings made of s~lastic(R) containíng 110mg of Levonorgestrel and 60mg of 17 Beta-estradiol, one with 50mm and the other with ~58mm of external diameter. These rings were compared with a combined pill containing 150mcg of Levonorgestrel and 30 mcg of Etinil-estradiol...Note: The complete abstract is available with the full electronic digital thesis or dissertations Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Faúndes, Anibal, 1931- (advisor), Universidade Estadual de Campinas.

2. Viana, Luci Martins. Estudo teorico das relações entre estrutura e atividade biologica : hormonios, esteroides e hidrocarbonetos policiclicos aromaticos.

Degree: 1981, Universidade Estadual de Campinas

Abstract: Using the PCILO rnethod, we studied which conformational factors were involved in the biological action of progesterone, corticosterone, cortisol and contraceptives - norethindrone, d-norgestrel, normethandrone and 17b-hidroxy-17-methylestra-4,15-dien-3-one. It was shown that the steroids in isolated state have generally similar conformations to observed ones in crystal state, indicating resistance to change of the conformation. This may be an indication that the steroids hormones react with receptors practically in the same crystalographic conformation. The biological activity of the studied contraceptives seems to be closely related to the preferred conformation of the side chain of the five-membered ring. Carcinogenic activity of the benzopyrene and pyrene was also studied using the v-technique method. It was predicted that the positions 6 and 1 in these molecules, respectively, are more susceptible to an electrophilic atack. Some properties of AH2 systems belonging to the first and second row of the periodical table, were investigated. Molecular geometry, electronic structure, dipole moment binding energy and others were calculated with the CNDO/2 method and analised by the Mulliken's overlap populations.

3. Corradi, Lara Silvia. Inibição da atividade das enzimas 5-alfa redutase e aromatase na prostata do gerbilo da Mongolia: 5-alpha reductase and aromatase enzymatic activies inhibition in the Mongolian gerbil prostate.

Degree: 2008, Universidade Estadual de Campinas

Abstract: Androgens have substantial role in the biology of the prostate, but estrogens also can affect the growth and differentiation of this gland. In specific tissues of the body, the ratio between androgens and estrogens can differ significantly from that found into plasma. The intracellular concentrations of these steroids in target tissues are mediated by a local hormone metabolism, by specifcs steroid-metabolizing enzymes, as the 5a-redutase (5a -r) and the aromatase (aro). In the prostate, the androgenic action is accented due to the conversion of testosterone in dihydrotestosterone by the activity of the 5a -r, while aro enzyme is an alternative pathway for the aromatization of testosterone into estrogens. These locally syntheses of steroids hormones assume thus, a great importance to the prostate cancer, where abnormal hormone levels can promote development and proliferation of malignancy to this gland. The activated functions of androgens and estrogens may be better understood focusing the maintenance of homeostatic prostatic epithelial-stromal interactions. Studies conducted with inhibitors of these specific enzymes have been carried out in an effort to clarify the real role of steroid-metabolizing enzymes in the maintenance of prostatic physiology, as well as into malignant progression prostatic cancer. After 30 consecutive days of inhibition, simultaneous or not, of the enzymes 5a -r and aro, respectively by Finasterida and Letrozol, the prostate of young, adult and old gerbils revealed that epithelial and estromal compartments were totally modified and reorganized in the attempt to adapt it to the new induced hormonal condition. Immediately after the end of drugs administration, in the early phase of the post-treatments period, the concentrations of testosterone and estrogens had been altered, the epithelial cells had their secretore activity pattern modified and, in the stromal compartment, the extracellular matrix was totally remodeled. The smooth muscle cells and fibroblasts became fenotipically modified. In the late phase of the post-treatments period, it was evident the attempt of the prostate gland in became morphologically and physiologically as a normal gland, however, this was not achieved in any analyzed gerbil. These steroids hormone metabolization blockade seems to be a good tool for the study of the epithelium-stroma interaction both in normal and abnormal prostate gland. Based on this data, it is suggested that the unbalance between androgens and estrogens intraprostatic concentrations provoked by Finasteride and Letrozol, together or not, interfered into the prostatic compartments interactions significantly. The results seem to be indicative of important signals of the new locally hormonal scene within the prostate gland. The recovery of balance hormonal concentrations of the prostate is damaged after the enzymatic blockade what gives, therefore, to this to 5a -r and aro enzymes, a status of crucial key for the normal and abnormal prostate gland.
