RESUMOObjetivos: Pouco se sabe sobre a atuação dos esteroides androgênicos anabolizantes (EAA) no cé-rebro humano e, por isso, resolvemos estudar a perda neuronal causada pelo uso e abuso de EAA em camundongos. Métodos
Introdução. Os esteroides anabólicos androgênicos (EAAs) são um grupo de compostos naturais e sintéticos formados pelo hormônio testosterona e seus derivados. A finalidade do presente estudo é analisar a densidade de células nervosas do cerebelo de camundongos. Método. Os camundongos machos, foram divididos em 4 grupos: G1: Controle (N=10), G2: Deca Durabolin® (N=10), G3: Durateston® (N=10) e G4: tratado com os dois anabolizantes (N=10), simultaneamente. Os camundongos foram tratados durante dois meses, recebendo as doses dos EAA e submetidos à natação três vezes na semana. Após a eutanásia dos animais, os cerebelos foram retirados, fixados e processados histologicamente. Os cortes foram tirados com 7μm e corados com violeta cresil e analisados por um microscópio acoplado a uma câmera e um software de análise para contagem dos corpos de neurônios. Resultados. Foram observadas diferenças nos resultados entre os animais do grupo controle (8,41) com os grupos que foram tratados com esteroides Deca Durabolin® (5,10≅39%), Durateston® (5,60≅33%) e com o grupo tratado com ambos anabolizantes (5,22≅38%). Conclusões. Desta forma, os resultados obtidos permitem concluir que houve uma diminuição, média dos grupos tratados com EAAs foi de 37%, na densidade de corpos de neurônios no córtex cerebelar.
Introduction: Androgenic anabolizing steroids (AAS) are a group of natural and synthetic compounds deriving from testosterone or one of its sub-products which are more and more used by young people for improving physical performance or for aesthetic reason. Complications, such as arteriosclerosis and acute myocardium infarction (AMI), have been reported in AAS' users, but the records about the ventricular anatomical structure of those users are few. Because of that, this study aimed to verify morphologic and quantitative morphometric possible alterations on mice's left ventricular myocardium submitted to their use. Materials and Methods: Thirty mice were divided into three 10-animals groups (group 1: received Deca-Durabolin ; group 2: received Potenay ; and group 3: received saline solution), each one of them composed by five males and five females, treated once a week and put to swimming thrice a week during one month. Results: Results revealed that there were no significant alterations in the quantity of muscle fibers in the animals treated with AAS but there were significant differences when comparing male-to-female mice and left ventricular area (µm2). It was observed that mice in group 1 (Deca-Durabolin ) presented a lesser left ventricular area when compared to those in group 3 (control) but, when analyzing cardiac muscle fibers morphologically, it was verified that the myocardium was looser and softer in drug-submitted animals, especially those in group 1 (Deca-Durabolin ). Conclusion: There are effective significant differences when a morphologic and quantitative morphometric analysis is done concerning mice's left ventricular myocardium submitted to AAS.

Efeito de doses supra fisiológicas de esteroides anabolizantes androgênicos no cerebelo de camundongos. ABSTRACTIntroduction. The androgenic anabolic steroids (AAS) are a group of natural and synthetic compounds formed by the hormone testosterone and its derivatives. The purpose of this study is analyzing the density of nerve cells in the mouse cerebellum. Method. The male mice strain were divided into 4 groups: G1: Control (N=10), G2: Deca Durabolin® (N=10), G3: Durateston® (N=10) and G4: They were treated with both anabolic (N=10) simultaneously. Those mice were treated for two months and received doses of AAS and were submitted to swimming three times a week. After euthanasia the animals the cerebellums were removed, fixed and processed histologically. The cut samples were taken with 7µm then stained with cresyl violet and after, analyzed by a microscopic coupled to a camera and analysis software to count the neurons bodies. Results. Differences were observed in the results among the control group (8.41) and the groups that were treated with steroid Deca Durabolin® (5.10≅39%), Durateston® (5.60≅33%), and the group treated with both Anabolic (5.22≅38%). Conclusions. Thus, it is possible to observe through the results obtained that there was a decrease, the average from treatment groups AAS was 37%, in the density of neuron bodies in the cerebellar cortex.
