1. Morfohistología testicular de Ceratophrys ornata (Bell) (Amphibia, Anura, Ceratophryidae)
This paper describes the morphohistological features of the testes of adult Ceratophrys ornata (Bell, 1843) (n = 5) from a wetland agroecosystem of central Argentina. The testes were processed by routine histological techniques, sectioned at 8 µm. The sheets obtained were stained with hematoxylin-eosin and Masson trichrome. The gonads are paired, yellowish,

2. Ablação endometrial com ácido tricloroacético em ratas: estudo histomorfométrico e histológico / Endometrial ablation using trichloroacetic acid in rat model: histomorphometric and histologic evaluation
INTRODUCTION: Dysfunctional uterine bleeding is one of the most prevalent causes of uterine bleeding and it is related to hormonal variations without organic causes. Endometrial ablation is a therapeutic option but the methods are frequently expensive and dependent of high cost technologies. The objective of the present study is to develop an animal model of

4. AvaliaÃÃo histolÃgica da reaÃÃo tecidual do fio de sutura à base de biopolÃmero de cana-de-aÃÃcar comparado com o adesivo tecidual etil-cianoacrilato e o mononylon 5-0Â: estudo em ratos
Introduction: The suture wires are materials used in the synthesis of surgical wounds or not, and the interaction of the wire with tissues during the cicatricial process, must have among others objectives, the absence of side effects. Objective: analyze by descriptive histologic study the characteristics of the tissue reply between the tissue adhesive ethyl-

5. Estudo clínico, radiográfico, microscópico e terapêutico de ameloblastomas / Clinical, radiographic, histopathologic and therapeutic study of ameloblastomas
Introduction: The ameloblastoma is a locally aggressive odontogenic neoplasm with important clinical implications. This study evaluated the effectiveness of ameloblastoma treatment comparing two therapeutic methods: curettage and curettage followed by cryotherapy. Method: Retrospective review of fifty three patients with ameloblastoma from the Service of Max

6. Non-ablative 1064 nm Nd:Yag in the treatment of facial atrophic acne scars in patients with skin types II-V: histological and clinical analysis / Estudo clínico e histopatológico das cicatrizes de acne em pacientes fototipo II-V após irradiação com o laser Nd:Yag 1064 nm
troduction: Post-acne scarring is a very distressing and difficult problem for both physicians and patients. Atrophic scar revision techniques, although numerous, have been hampered by inadequate clinical responses and prolonged postoperative recovery periods. Nonablative laser treatment has shown significant effect on dermal collagen remodeling with minimal

7. Avaliação da capacidade de limpeza promovida pela instrumentação rotatória associada a uma manobra complementar para o terço apical de canais achatados / Evaluation of the cleaning capacity achieved by rotary instrumentation associated with a complementary maneuver for cleaning of the apical third of flattened canals
The aim of this study was to compare by histological and morphologic analisys the cleaning ability of rotary instrumentation associated to a proposed complemental maneuver for the apical third of flattened root canal. Twenty-four human mandibular incisors, with single root canal and anatomic diameter corresponding to the instrument 20, were distributed in 3

8. Parametros pre, intra e pos-operatorios em mulheres submetidas a histerectomia vaginal na ausencia de prolapso uterino
Introduction: Vaginal hysterectomy represents the best performance procedure to the removal of the uterus, based on many evaluated factors, when compared to abdominal hysterectomy or even laparoscopic hysterectomy. Despite many well known advantages of vaginal hysterectomy, most surgeons among us only indicate it to women with prolapsed uterus, being very fe

9. Physical activity and neuroprotection in adult mice after pilocarpine induced status epilepticus / Atividade fisica e neuroproteção em camundongos adultos após indução de status epilepticus por pilocarpina
Pilocarpine-induced epilepsy in mice is an experimental model of the Temporal Lobe Epilepsy (TLE). Status epilepticus determined by pilocarpine adminstration leads to behavioral and electroencephalographic changes and neuronal damage similar to those observed in TLE. Recently, it has been shown that physical activity exerts neuroprotective effects, such as i

10. "Endotelização in vivo das biopróteses cardíacas porcinas: comparação entre a preservação convencional e a não-aldeídica" / In vivo endothelialization of conventional and non-aldehyde-fixed porcine bioprostheses: comparative study
O revestimento completo das superfícies das biopróteses cardíacas por uma camada protetora de células endoteliais do hospedeiro ainda não foi relatado. As próteses cardíacas de uso corrente são comumente preservadas em glutaraldeído, o qual é citotóxico para as células do hospedeiro evitando a endotelização espontânea. O objetivo deste estudo

11. A New Method for Fixing Biomphalaria glabrata for Histologic Studies, Using Shell Perforation
A new technique for fixation of Biomphalaria glabrata for histologic studies is described. It consists in performing several external holes in the shell, before placing the entire snail into the fixative. It is a very practical and quick procedure that showed excellent results when compared to the usual techniques.

12. Injeções intradermicas de colageno e suas implicações na matriz extracelular
In the present work the extracellular matrix responses to intradermic heterologous collagen injections and the evaluation of the effects of the injected material physically and chemically treated were studied. Mice were injected with type 1 bovine collagen (gel, gel formolized and lyophyllized collagen solutions) and sacrificed at different intervals of time
