| The objective of this work was identify the presence of interstitial cells of Cajal, muscle cells, nerves and androgen receptor positive cells in adult human testicle, using immunohistochemical detection for c-kit/CD-117, actin smooth muscle specific (ASMS), neurofilament (N) and androgen receptor (AR), respectively. The samples were obtained from patients (n= 10) with diagnosis of prostate cáncer, with surgery of orchiectomy. Subsequently were processed by histology and for immunohistochemistry using specific antibodies. It showed the presence of cells c-kit/CD-117, with diverse degrees of positivity, distributed mainly in the interstitial peritubular área of the human testicle. The peritubular myoides cells were positive to the presence of the actin... |

| El análisis seminal o espermiograma es uno de los parámetros más usados en la evaluación de la fertilidad masculina. La OMS (WHO, 2010), presentó el 5 Manual para el examen y procesamiento del semen humano, documento que fue analizado durante el primer taller de estandarización del análisis seminal (PLEAS), realizado en Santiago de Chile, mayo del 2010. Posteriormente se aplicaron los nuevos valores indicados como "límite de referencia inferior" (LIR), en el estudio del análisis seminal realizados por varios autores (2003 al 2010). Los resultados obtenidos indican que el 81% de los investigadores latino americanos creen que el nuevo manual estandariza mejor la concentración espermática, un 96% está de acuerdo con la nueva subclasificación en la motilidad... |

| Boron is a chemical element widely used in many industrial activities. Exposure to it affects many organs in mammals, mainly reproductive male organs. This work evaluates boron effect in testis. For this purpose, 12mg Boron/L of drinking water, equivalent to Arica tap water, was given for 42 days to 85 days old CFl male mice (experimental group). Another group (control group) drunk tap water of Santiago (0.6mg Boron/L) was used. Testicular histopathology and morphometric analysis was done. These studies showed that Borum induces alterations such as epithelial vacuolization, blockage of the tubular lumen and atrophy. Morphometrical data showed that Borom induces also enlargement of tubular diameter, epithelial height and tubular lumen. Therefore, it is... |
