Estudaram-se os efeitos da ovarioisterectomia na densidade mineral óssea de cadelas e da reposição de estrógenos após a cirurgia. Foram utilizadas 12 cadelas, sem raça definida, entre dois e seis anos de idade e pesos entre 5 e 15kg. Os animais, submetidos à ovarioisterectomia, foram separados em dois grupos de seis. Um grupo serviu como controle, e o outro recebeu estrógenos naturais conjugados na dose de 0,01...
INTRODUCTION: It is estimated that genitourinary anomalies comprise 20% of all antenatally detected fetal anomalies, and pyelocaliectasia is the most common one. Detection of antenatal dilatation of the urinary tract does not always indicate postnatal urinary tract obstruction or even a significant genitourinary anomaly. Most cases will improve spontaneously, representing a temporary physiologic impedence and d...
The real impact of taxes on the economy can only be assessed when we consider the behavioral responses of economic agents due to these taxes. Two kinds of responses are studied in this thesis: changes in organizational form and location choices. The first part of this study shows how income taxation in Brazil gives incentives to some classes of taxpayers to incorporate in order to reduce their tax burden. Micro...
In the last few years, ovarian ablation with GnRH agonists has been used as first-line adjuvant therapy in pre and perimenopausal breast cancer. These drugs suppress ovarian function in the hypothalamic-pituitary axis and they have adverse effects in other end-organs. A retrospective study was conducted on 35 premenopausal women, with breast cancer, and treated with goserelin, in order to investigate the effect...
Uterine tumors resembling ovarian sex-cord tumors are rare and few cases are published in the literature. The authors describe a recently diagnosed one. The clinical features consisted of: abnormal vaginal bleeding and enlargement of the uterus, which allowed confusion with several types of uterine pathology: benign or malignant one; the diagnosis is exclusively histopathological. These tumors have a benign bio...
Isolates of Plasmodium falciparum from three areas of West Africa were recovered from cryopreservation and their chloroquine-sensitivity were determined in vitro. Of the 90 samples studied, 60 were from Guinea-Bissau (30Resistant/30Sensitive), 15 were from S. Tomé and Príncipe (11Resistant/4Sensitive) and 15 were from Angola (11Resistant/4Sensitive). All the isolates were sensitive to mefloquine. Using the poly...
A padronização de um fitoterápico é etapa imprescindível para garantia da qualidade de medicamentos contendo plantas medicinais. Objetivou-se padronizar Syzygiam cumini (L.) Skeels e para tanto se estabeleceram parametros tais como, avaliação morfoanatômica das folhas, morfológica das flores e dos frutos, avaliação granulométrica da droga rasurada (frutos), determinação da umidade, avaliação dos processos de se...
Os autores propõem procedimentos para estabelecer o controle de qualidade da própolis. Para tanto, foram adaptadas e executadas técnicas farmacopéicas e/ou desenvolvidas técnicas novas. Foram estabelecidos perfis dos teores de flavonóides, de ceras, de substâncias voláteis totais (através da perda por dessecação) e de cinzas totais. Os valores obtidos para as amostras de própolis estudadas, coletadas em um apiá...
