ABSTRACT

The aim of this work was to study effects of ketotifen fumarate (KF) on prevention of tissue damage in testes of rats with experimental autoimmune orchitis (EAO) and on the contralateral testis in a model of prolonged testicular cord torsion (TCT). Rats with EAO or TCT were injected intraperitoneally once daily with KF or saline solution (vehicle group). Incidence and severity of testicular damage were evaluated by histopathology using an EAO score or a Johnsen score. Mast cells (MC) were identified by histochemistry and quantified. In EAO model, KF significantly reduced severity of histopathological testicular damage compared to rats in the vehicle group. KF also reduced the number of testicular MC compared to vehicle group. Similarly, in TCT model, multifocal damage of the contralateral testis was observed 30 days after testicular torsion characterized by sloughing of the germinal epithelium, seminiferous tubule atrophy, and interstitial edema. Focal signs of inflammation and fibrosis of seminiferous tubular walls were also observed. In contrast, sections of contralateral testis of rats injected with KF and killed 30 days after surgery showed normal histological features. A significant decrease in the number of MC was observed in rats treated with KF compared to untreated animals. In conclusion, we demonstrated that treatment with KF reduced testicular inflammatory process and MC infiltrates in both EAO and TCT models. The results suggest a promising treatment for infertile male patients with testicular pathologies associated with inflammation and germ cell loss.

ABSTRACT

O objetivo deste artigo é relatar um caso de orquiepididimite associado com infecção por Salmonella enterica subespécie diarizonae em carneiro da raça Santa Inês de quatro anos de idade, vasectomizado. Ao exame clínico reprodutivo, o animal mostrou aumento severo do conteúdo escrotal, sendo o testículo direito maior do que o esquerdo e a cauda do epidídimo direita maior do que a esquerda. A consistência testicular, avaliada em escala de 1 a 5, foi 5 para o testículo direito e 2,5 para o esquerdo; o órgão apresentava-se muito sensível ao toque. Na ultrassonografia foram observadas estruturas anecoicas/hipoecoicas circulares na cauda do epidídimo, sugestivas de abscessos; alguns pontos hiperecogênicos no parênquima testicular, sugerindo lesões de calcificação; e todo o testículo direito rodeado por imagem hipoecoica, indicativa de edema. Uma das estruturas da cauda do epidídimo direita foi puncionada, encontrando-se exsudato purulento, o qual foi enviado para exame microbiológico, sendo isolada e identificada Salmonella enterica subespécie diarizonae. O carneiro foi submetido a orquiepididectomia, e o órgão foi caracterizado macroscopicamente por adesões fibrosas entre as camadas escrotais, coexistência de abscessos epididimários e degeneração testicular. A Salmonella enterica subespécie diarizonae deve ser considerada no diagnóstico diferencial de infecção genital em ovinos.


The objective of this manuscript was to report a case of orchiepididymitis associated with Salmonella enterica subespécie diarizonae infection in a vasectomized 4-year-old Santa Inês ram. In the clinical-reproductive examination, the animal showed a severe enlargement of the scrotal contents, being the right testicle larger than left, and the right epididymal cauda was higher than the left. The testicular consistency, evaluated in a scale from 1 to 5, was 5 to the right and 2.5 to the left, and the organ was very sensitive to the touch. In the ultrasound circular structures anechoic/hypoechoic in the epididymal cauda were observed, and in the parenchyma of testicles some points of hyperechogenic image, suggesting calcification lesions and the entire right testicle was surrounded by hypoechoic image, indicative of edema. One of those structures of the right epididymal cauda was aspirated and a purulent exsudate was found, which was sent to microbiological exam, was isolated and identified Salmonella enterica subespécie diarizonae. The ram was submitted to orchiepididectomy, and the organ was characterized macroscopically by fibrous adhesions between scrotum layers, coexistence of epididymal abscesses and testicular degeneration. The Salmonella enterica subspecie diarizonae must be taken into account in the differential diagnosis of ovine genital infections.

ABSTRACT

A púrpura de Henoch-Schonlein (PHS), também conhecida como púrpura anafilactóide ou púrpura reumática, é a vasculite mais frequente na faixa etária pediátrica. Geralmente, a doença é benigna, com a manifestação clínica característica - púrpura palpável não plaquetopênica, presente em todos os pacientes, e de localização simétrica em membros inferiores e nádegas...

ABSTRACT

Os autores estudaram do ponto de vista micologico, imunoquimico e de sua biologia molecular, duas amostras de Paracoccidioides brasiliensis, uma isolada do solo, no municipio de IBIA (MG) por Silva-Vergara et al (1996,1998) denominada IBIA e outra, BAT, cultivada de um caso humano de paracoccidioidomicose em Ribeirao Preto (SP) por Freitas da Silva (1996). Tais amostras apresentam colonias cotonosa (M) e leveduriforme (L ou Y), sendo patogenicas para cobaios inoculados por via testicular, produzindo orquite granulomatosa e/ou supurativa. Do ponto de vista imunoquimico, atraves de provas de Imunodifusao dupla, Imunoeletroforese e Western Blotting, foi demostrada a presenca da gp43

ABSTRACT

La capacidad antigénica del homogeneizado testicular ha sido utilizada para establecer diferentes modelos de respuesta autoinmune en animales. En este trabajo, se propone desarrollar un modelo de orquitis autoinmune en ratones machos de la cepa A/Sw, utilizando homogeneizado testicular homólogo. Grupos de ratones recibieron vía subcutánea, inyecciones de homogeneizado testicular en diferentes dosis, emulsionado con adjuvante de Freund Completo. Posteriormente se sacrificaron para obtener suero, utilizando un test inmunológico y gónadas para el estudio histológico. Se evalúan los elementos celulares del epitelio germinativo, describiendo las modificaciones del mismo y se determina la presencia de anticuerpos por inmunodifusión. Se propone la utilización de las condiciones descritas, como un modelo de orquitis autoinmune en ratones
