The article discusses research which examined the morphological development of the digital coronary region in different stages of Holstein cattle fetal life.

Contents The lectin-binding pattern was compared in the normal and pathological uterus of sows during the ovarian cycle. The following biotinylated lectins were used: Con A, DBA, SBA, PNA, RCA-I, UEA-I and WGA. Glycoconjugate labelling showed differences between phases of ovarian cycle and presence of morphologic lesions. Cystic endometrial hyperplasia increased the RCA-I reaction in the apical region of the glandular epithelium. There was higher intensity of labelling of WGA in the glandular epithelium in uteri with endometritis. In addition, increased Con A binding in the glandular epithelium and mild reduction of UEA-I reactivity in the glycocalyx of the glandular epithelium were detected in the cases of endometritis. The results of this study show that morphologic alterations modify the sugar pattern in the porcine uterus. These modifications in glycoconjugates may be one of the reasons for decreased fertility in sows. [ABSTRACT FROM AUTHOR]

This study was carried out to compare the lectin-binding pattern in the normal and pathological oviduct of sows during the ovarian cycle. Lectin-binding patterns showed differences between segments, phases of ovarian cycle and presence of morphologic lesions. In the infundibulum, it was observed that the cysts, in the follicular phase, reducedRicinus communis-I (RCA-I) andUlex europaeus-I (UEA-I) binding. Furthermore, in the pathological oviducts of the luteal-phase group, there is a reduction ofConcanavalia ensiformis(Con-A) reactivity in this segment of the tube having wall cysts, adenomyosis and diverticulus. TheArachis hypogaea(PNA) binding in the infundibulum, during the luteal phase, decreased in the tube having adenomyosis. In animals with wall cysts, the Con-A,Triticum vulgaris(WGA) and RCA-I reactivity was minor in the glycocalyx of the isthmus epithelium during follicular phase. Con-A andDolichos biflorus(DBA) binding pattern was minor in the luteal-phase isthmus of the tube having wall cysts, adenomyosis and diverticulus. In the ampulla, the wall cysts impaired the Con-A reaction only in the basal region of the epithelium, in the follicular phase. Binding with Con-A was decreased in the ampulla of animals in the luteal phase in the tube lesions with cysts and diverticulus. In addition, the diverticulus observed in the ampulla, during the luteal phase, reduced the PNA tubaric binding.The results of this study showed that the morphologic alterations modify the sugar pattern in the oviduct of sows. These modifications in glycoconjugates may be one of the reasons for the failure of fertility in sows. [ABSTRACT FROM AUTHOR]

Canine visceral leishmaniosis (CVL) is an important zoonotic disease, which is endemic in Brazil and several other parts of the world. The disease may affect multiple organs, but lesions in the oral cavity are considered uncommon. Twenty-three cases of oral lesions compatible with CVL were diagnosed from 2015 to 2018 in the Federal District, Brazil. Six cases were confirmed to be CVL based on histopathology, immunohistochemistry and polymerase chain reaction amplification of Leishmania infantum kDNA. Most of the affected dogs were >9 years of age, of mixed breed and were classified as having stage C of the disease. The most important gross findings were ulcerated nodular lesions in the tongue, lip, gingiva and hard palate. Microscopically, there was lymphoplasmacytic to granulomatous inflammation that was diffuse, moderate to severe and associated with ulceration. CVL should be considered in the differential diagnosis of nodular and ulcerative oral lesions in dogs., (Copyright © 2019 Elsevier Ltd. All rights reserved.)
