1. Mongolian Gerbils as a Model for the Study of Cholesteatoma: Otoendoscopic as a Diagnostic Tool
Abstract Introduction Cholesteatoma is a disease with significant clinical impact but is incompletely understood. The challenge of performing studies with long-term follow-up in humans is a factor that has restricted the advance of knowledge in this field. Thus, the use of animal models is highly pertinent, and the Mongolian gerbil model has emerged as one

2. Desenvolvimento da próstata masculina e feminina do gerbilo da Mongólia submetido à exposição no período embriofetal e pós-natal de etinilestradiol / Development of male and female prostate of the Mongolian gerbil submitted to the exposure embryofetal period and postnatal ethinylestradiol
In males, prostatic morphogenesis is an event controlled by androgens, which act directly via paracrine factors secreted by the mesenchyme. In females, the embryological development of the prostate appears to occur in environment low levels of steroid hormones, but the presence of these hormones in the adult life induces differentiation and secretory activit

3. Aspectos morfofuncionais da prostata feminina do gerbilo durante o cilco estral : estudos estruturais e caracterização do perfil secretor / Morphofunctional aspects of the gerbil female prostate during the estrous cycle : structural analysis and characterization on the secretory profile
The prostate is not an exclusive organ of the male reproduction system, found in females of several rodents species and also in humans. The female prostate has been considered homologue to the male ventral prostate and it is formed by a small cluster of glands and ducts inserted into a fiber muscular stroma. In adult female Mongolian gerbils (Meriones unguic

4. Testicular development of the Mongolian gerbil : postnatal differentiation of germ and Leydig cells / Desenvolvimento testicular no gerbilo da Mongolia : diferenciação pos-natal das celulas germinativas e de Leydig
O gerbilo da Mongólia (Meriones unguiculatus) tem sido utilizado de maneira crescente em estudos sobre o sistema genital masculino. Alguns aspectos da espermatogênese e o ciclo do epitélio seminífero dessa espécie são conhecidos, mas investigações sobre o desenvolvimento pós-natal do testículo e diferenciação das suas principais populações celu

5. 5-alpha reductase and aromatase enzymatic activies inhibition in the Mongolian gerbil prostate / Inibição da atividade das enzimas 5-alfa redutase e aromatase na prostata do gerbilo da Mongolia
Os andrógenos têm papel central na biologia da próstata, mas os estrógenos também podem afetar o crescimento e a diferenciação desta glândula. Em tecidos específicos do corpo, a proporção entre andrógenos e estrógenos pode diferir significativamente daquela encontrada no plasma sanguíneo. As concentrações intracelulares desses esteróides nos

6. Hormonal regulation of the Mongolian gerbil female prostate : alterations caused by senescence and hormonal supplementation (DHEA) / Regulação hormonal da prostata feminina do gerbilo da Mongolia : alterações decorrentes da senescencia e mediante a suplementação hormonal pela deidroepianadrosterona (DHEA)
In contrast to the classic boarding, the prostate is not an exclusive gland of the male organism and it can be found in mammal females, including humans and rodents. The precise comprehension of the post-natal development and possible histopathological processes related to this gland are difficult because of its anatomical paraurethral localization and it re

7. Experimental carcinogenesis in the ventral Mongolian s gerbil prostate / Carcinogenese experimental no lobulo ventral da prostata do geribo da Mongolia
The prostate cancer is the most common tumor that attacks men from the 50 s decade. Among the risk factors that contribute to this disease s increase stand out the aging process, when hormonal unbalances happen frequendy. Developmental studies of prostatic tumors have been complicated because of difficult in obtaining human material, once this question lies

8. Androgen receptors expression in the Mongolian gerbil ventral prostate / Expressão de receptores androgenicos no lobulo ventral da prostata do gerbilo da Mongolia
The normal growth, differentiation and maintenance of the morphofunctional integrity of the prostate gland are dependent on the interaction of constant levels of androgens with their receptors. The need to study the responses to hormones under several conditions and the effect of their blockage is due to the fact that the human prostate is the site of a grea

10. Succinic dehydrogenase activity during palate formation in the Mongolian gerbil.
The palatal shelf epithelium of the Mongolian gerbil was examined for succinic dehydrogenase activity prior to, during and the after palatal fusion (days 18-20 post coitus). Enzyme activity was present during all stages examined, and was noted even in the epithelial pearls of fused palates. The presence of SDH activity in these epithelial pearls lends suppor

11. Platelet aggregation in platelet suspensions from Mongolian gerbils (Meriones unguiculatus).
Blood obtained from Mongolian gerbils (Meriones unguiculatus) by cardiac puncture was used to develop a method for preparing platelet suspensions suitable for biochemical and aggregometric studies. The aggregation responses of gerbil platelet suspensions to 10 microM adenosine diphosphate and to 0.2 U/mL thrombin were immediate and irreversible. In addition,

12. Cecal and fecal bacterial flora of the Mongolian gerbil and the chinchilla.
The Mongolian gerbil is being increasingly used as a laboratory animal and as a pet. Both chinchillas and gerbils are used as animal models for otitis media and other otic research. Previously, only incomplete information was available regarding the indigenous bacterial flora of the lower intestinal tracts of these coprophagic animals. Using the strict anaer
