El objetivo del estudio fue evaluar las tesis desarrolladas en la Facultad de Medicina Veterinaria y Zootecnia de la Universidad Peruana Cayetano Heredia (FAVEZ-UPCH) durante el periodo 2012-2017. Para ello se diseñó un estudio observacional, descriptivo, retrospectivo, que utilizó herramientas bibliométricas para sistematizar la información de la base de datos del Banco de Tesis de la FAVEZ-UPCH. Se estudiaron las siguientes variables: año de sustentación, calificación de la tesis, línea de investigación, diseño de estudio, individuos u objeto de estudio, especie o muestra especifica evaluada, área o laboratorio del asesor principal, literatura utilizada, literatura actualizada y tesis transformada en artículos. La información obtenida se resumió mediante estadística descriptiva. Se evaluaron 195 tesis. El mayor número de tesis se sustentó durante el año 2014 (22,6%)....

The histological description of ovarian follicles of the 12, 18 and 24-month-old paiche (Arapaima gigas) from a fish farm in Iquitos in May 2018 was performed using a convenience sampling. Nine, 13 and 4 fish ovaries of 12, 18 and 24 months, respectively were used. A follicular classification was developed based on the follicular characteristics and based on this, the ovarian follicular ratio, follicular diameters, and the percentage of follicular atresia were determined. The following phases are considered: Perinucleolar (PN), Endogenous vitellogenesis I (VE1), Endogenous vitellogenesis II (VE2) and exogenous vitellogenesis (VEX). The highest frequency of PN follicles was presented at the age of 12 months (p<005), with no significant differences in the frequency of VE1 follicles at 18 and 24 months. VE2 and VEX stages were only observed at 24 months of age. No significant difference ...

The aim of this study was to analyse the histological characteristics of the liver of the llama. Twenty adult llamas, males and females, with an average age of two years were studied. Samples were processed using the following techniques: haematoxylin-eosin staining, Masson's trichrome stain, reticulin, orcein, PAS, immunohistochemistry, and transmission electron microscopy. The characteristics of the liver parenchyma and stroma were similar to those found in other mammals. However, interlobular connective tissue similar to that described for the genus Camelus was not observed. The differences in the liver of the species of the Camelus and Lama genuses showed the need to carry out studies of the organs in all species and highlights the importance of not generalizing from other species of the same family.
